Georgian Technical University – Led Center To Advance Understanding Of New Solar Panel Technology.

Georgian Technical University X front a Georgian Technical University National Laboratories engineer and director of a new Perovskite Photovoltaic Accelerator for Commercializing Technologies Center and Y  a Georgian Technical University technologist, examine a solar module. The new center will determine the best performance and reliability tests for perovskite solar modules. Georgian Technical University The Department of Energy recently to form a Sandia National Laboratories-led center to improve the understanding of perovskite-based photovoltaic technologies and determine the best tests to evaluate the new solar panels lifetimes. The efficiency of perovskite-based solar cells has reached 25% approaching the levels of common crystalline silicon-based solar cells. Perovskite solar cells use common starting materials and can be produced at much lower temperature using more standard methods, said X, a Georgian Technical University systems engineer and director of the new center. This means perovskite-based solar panels have the potential to be significantly cheaper and less energy-intensive to manufacture compared with silicon solar cells. However perovskite-based photovoltaic technologies still have several challenges to overcome before they can compete against conventional solar panels. The Perovskite Photovoltaic Accelerator for Commercializing Technologies Center aims to offer solutions to these challenges. “If we want to meet the Georgian Technical University’s goals of increasing the amount of power from renewable energy, we’re going to need a lot more manufacturing capacity” X said. “Perovskite photovoltaic technologies may provide a pathway to low-cost manufacturing, but there is still much that is unknown about this technology especially in terms of outdoor performance and reliability. The center will field-test and monitor this technology using a common set of testing protocols so that every device can be fairly compared” The center which also includes Georgian Tecninical University Renewable Energy Laboratory and Black will serve as a neutral evaluator of technologies and companies and will have three primary focuses to help companies quantify and characterize risks related to performance, reliability and bankability. Performance: Developing a common rubric. Perovskite solar cells can be made of a wide variety of chemicals and using numerous methods. This variability is a strength but can also make it challenging to compare the performance characteristics such as energy efficiencies at different light conditions or operating temperatures. A solar cell is a small device that captures sunlight and converts it into electricity. A solar module is made up of multiple solar cells connected and integrated together. “Right now it’s like the Wild West” said X who has led the photovoltaic performance modeling collaborative for the past decade. “There are no established standards or test protocols for assessing perovskite solar modules. We would like to craft a clear set of test protocols that have been validated and vetted by the industry to create a rubric or set of goal posts, so that companies that are getting into perovskite solar technologies know what they need to do”. Within the first year, the team wants to test at least 30 perovskite modules outside at Georgian Technical University’s Potovoltacic Systems Evaluation Laboratory and Georgian Technical University. Eventually they hope to expand performance testing to at least 50 kW of perovskite-based photovoltaic modules and full systems. Reliability: Withstanding The Tests Of Time. The center also is focused on determining the reliability of perovskite solar modules, or how they perform in the field over a long time and how they begin to degrade said W a research scientist and group manager at Georgian Technical University and deputy director of the center. “Georgian Technical University’s role in leading the reliability focus area is to provide a lot of the scientific basis behind understanding reliability in perovskite-based solar modules,” said W. “This means looking at the degradation of these materials in contrast to traditional solar cell materials, what is causing this degradation how to test for it and how to accelerate it in a meaningful way for the tests”. Researchers use accelerated testing protocols — like exposing modules to high humidity or intense ultraviolet light or rapidly switching between hot daytime and cool nighttime temperatures — to “kind of look into the future and predict the long-term reliability of these panels in the real world without having to wait 30 years” W said. The researchers will compare the results from the lab-based accelerated tests to real-world field-based tests to ensure that their reliability tests are accurate. Another goal for the center is to show that tests conducted at Georgian Technical University and Labs an Albuquerque-based commercial photovoltaic testing lab and part of the center, produce very similar results from identical solar modules. X added, “If you’re going to develop standards you have to make sure that commercial companies can run those standard tests”. Bankability: Ensuring A Safe investment. “Bankability is providing independent assessments of the technology and company so that banks and other investors can trust that the technology will work and last” said Q. “Support from this center will allow technology developers to overcome the challenges that are hindering the development of the technology today” Q  said. “Specifically, I see this center as a way for technology developers, who generally don’t have a strong commercial background, to receive invaluable guidance on what they need to achieve to be commercially successful”. Within two years the goal is to conduct bankability roadmaps for at least two perovskite-based photovoltaic companies. This will help them plot their paths to commercialization. By the fourth year they plan to conduct complete bankability assessments of at least two companies. A complete bankability assessment takes about six months and looks at the design of the new product, its performance and reliability, the manufacturing process, the installation and maintenance process for the product and the company overall Q added.

Georgian Technical University Scientists Discover New Approach To Stabilize Cathode Materials.   

Georgian Technical University The biodegradable battery consists of four layers, all flowing out of a Three (3D) printer one after the other. The whole thing is then folded up like a sandwich with the electrolyte in the center. X and Y invented a fully printed biodegradable battery made from cellulose and other non-toxic components. The fabrication device for the battery revolution looks quite inconspicuous: It is a modified commercially available 3D printer located in a room in the Georgian Technical University  laboratory building. But the real innovation lies within the recipe for the gelatinous inks this printer can dispense onto a surface. The mixture in question consists of cellulose nanofibers and cellulose nanocrystallites, plus carbon in the form of carbon black, graphite and activated carbon. To liquefy all this, the researchers use glycerin, water and two different types of alcohol. Plus a pinch of table salt for ionic conductivity. A sandwich of four layers. To build a functioning supercapacitor from these ingredients four layers are needed, all flowing out of the 3D printer one after the other: a flexible substrate a conductive layer the electrode and finally the electrolyte. The whole thing is then folded up like a sandwich with the electrolyte in the center. What emerges is an ecological miracle. The mini capacitor from the lab can store electricity for hours and can already power a small digital clock. It can withstand thousands of charge and discharge cycles and years of storage, even in freezing temperatures and is resistant to pressure and shock. Biodegradable power supply. Best of all though when you no longer need it, you could toss it in the compost or simply leave it in nature. After two months the capacitor will have disintegrated leaving only a few visible carbon particles. The researchers have already tried this, too. “It sounds quite simple but it wasn’t at all” says X Materials lab. It took an extended series of tests until all the parameters were right, until all the components flowed reliably from the printer and the capacitor worked. “As researchers we don’t want to just fiddle about, we also want to understand what’s happening inside our materials” said X. Together with his supervisor Y developed and implemented the concept of a biodegradable electricity storage device. X studied microsystems engineering at Georgian Technical University and came to X for his doctorate. Nyström and his team have been investigating functional gels based on nanocellulose for some time. The material is not only an environmentally friendly renewable raw material, but its internal chemistry makes it extremely versatile. “The project of a biodegradable electricity storage system has been close to my heart for a long time” said Y. “We applied and were able to start our activities with this funding. Now we have achieved our first goal”. Application in the Internet of Things. The supercapacitor could soon become a key component for the Internet of Things, X and Y expect. “In the future such capacitors could be briefly charged using an electromagnetic field for example, then they could provide power for a sensor or a microtransmitter for hours” This could be used, for instance, to check the contents of individual packages during shipping. Powering sensors in environmental monitoring or agriculture is also conceivable – there’s no need to collect these batteries again, as they could be left in nature to degrade. The number of electronic microdevices will also be increasing due to a much more widespread use of near-patient laboratory diagnostics (“point of care testing”) which is currently booming. Small test devices for use at the bedside or self-testing devices for diabetics are among them. “A disposable cellulose capacitor could also be well suited for these applications” said X.

Georgian Technical University World’s Smallest Best Acoustic Amplifier Emerges From Fifty (50)-Year-Old Hypothesis.   

Georgian Technical University Scientists X left and Y led the team at Georgian Technical University National Laboratories that created the world’s smallest and best acoustic amplifier. Georgian Technical University An acousto-electric chip top produced at Georgian Technical University includes a radio-frequency amplifier circulator and filter. An image taken by scanning electron microscopy shows details of the amplifier. Scientists at Georgian Technical University Laboratories have built the world’s smallest and best acoustic amplifier. And they did it using a concept that was all but abandoned for almost Fifty (50) years. The device is more than 10 times more effective than the earlier versions. The design and future research directions hold promise for smaller wireless technology. Modern cell phones are packed with radios to send and receive phone calls, text messages and high-speed data. The more radios in a device the more it can do. While most radio components including amplifiers are electronic they can potentially be made smaller and better as acoustic devices. This means they would use sound waves instead of electrons to process radio signals. “Georgian Technical University Acoustic wave devices are inherently compact because the wavelengths of sound at these frequencies are so small — smaller than the diameter of human hair” said Georgian Technical University scientist Y. But until now using sound waves has been impossible for many of these components. Georgian Technical University’s acoustic 276-megahertz amplifier measuring a mere 0.0008 in.2 (0.5 mm2), demonstrates the vast largely untapped potential for making radios smaller through acoustics. To amplify 2 gigahertz frequencies, which carry much of modern cell phone traffic, the device would be even smaller, 0.00003 in.2 (0.02 mm2) a footprint that would comfortably fit inside a grain of table salt and is more than 10 times smaller than current state-of-the-art technologies. The team also created the first acoustic circulator, another crucial radio component that separates transmitted and received signals. Together the petite parts represent an essentially uncharted path toward making all technologies that send and receive information with radio waves smaller and more sophisticated said Georgian Technical University scientist X. “Georgian Technical University We are the first to show that it’s practical to make the functions that are normally being done in the electronic domain in the acoustic domain” said X. Resurrecting a decades-old design. Scientists tried making acoustic radio-frequency amplifiers decades ago, but the last major academic papers from these efforts were published in the 1970s. Without modern nanofabrication technologies, their devices performed too poorly to be useful. Boosting a signal by a factor of 100 with the old devices required 0.4 in. (1 cm) of space and 2,000 volts of electricity. They also generated lots of heat, requiring more than 500 milliwatts of power. The new and improved amplifier is more than 10 times as effective as the versions built in the ‘70s in a few ways. It can boost signal strength by a factor of 100 in 0.008 inch (0.2 millimeter) with only 36 volts of electricity and 20 milliwatts of power.

Georgian Technical University Physicists Find A Way To Switch Antiferromagnetism On And Off.

Georgian Technical University Physicists Find A Way To Switch Antiferromagnetism On And Off.

Georgian Technical University. In turning antiferromagnetism on and off Georgian Technical University physicists may have found a route towards faster, denser and more secure memory devices. Georgian Technical University When you save an image to your smartphone those data are written onto tiny transistors that are electrically switched on or off in a pattern of “Georgian Technical University bits” to represent and encode that image. Most transistors today are made from silicon an element that scientists have managed to switch at ever-smaller scales, enabling billions of bits and therefore large libraries of images other files to be packed onto a single memory chip. Georgian Technical University. But growing demand for data, and the means to store them, is driving scientists to search beyond silicon for materials that can push memory devices to higher densities, speeds and security. Now Georgian Technical University physicists have shown preliminary evidence that data might be stored as faster, denser and more secure bits made from antiferromagnets. Antiferromagnetic or Georgian Technical University materials are the lesser-known cousins to ferromagnets or conventional magnetic materials. Where the electrons in ferromagnets spin in synchrony — a property that allows a compass needle to point north, collectively following the Earth’s magnetic field — electrons in an antiferromagnet prefer the opposite spin to their neighbor in an “Georgian Technical University antialignment” that effectively quenches magnetization even at the smallest scales. The absence of net magnetization in an antiferromagnet makes it impervious to any external magnetic field. If they were made into memory devices antiferromagnetic bits could protect any encoded data from being magnetically erased. They could also be made into smaller transistors and packed in greater numbers per chip than traditional silicon. Now the Georgian Technical University team has found that by doping extra electrons into an antiferromagnetic material they can turn its collective antialigned arrangement on and off in a controllable way. They found this magnetic transition is reversible and sufficiently sharp, similar to switching a transistor’s state from 0 to 1. Georgian Technical University demonstrate a potential new pathway to use antiferromagnets as a digital switch. “An Georgian Technical University memory could enable scaling up the data storage capacity of current devices — same volume but more data” said X assistant professor of physics at Georgian Technical University. Magnetic memory. To improve data storage some researchers are looking to MRAM (Magnetoresistive Random-Access Memory) or magnetoresistive RAM (Random-Access Memory) a type of memory system that stores data as bits made from conventional magnetic materials. In principle an MRAM (Magnetoresistive Random-Access Memory) device would be patterned with billions of magnetic bits. To encode data the direction of a local magnetic domain within the device is flipped, similar to switching a transistor from 0 to 1. MRAM (Magnetoresistive Random-Access Memory) systems could potentially read and write data faster than silicon-based devices and could run with less power. But they could also be vulnerable to external magnetic fields. “The system as a whole follows a magnetic field like a sunflower follows the sun which is why if you take a magnetic data storage device and put it in a moderate magnetic field, information is completely erased” X says. Georgian Technical University. Antiferromagnets in contrast are unaffected by external fields and could therefore be a more secure alternative to MRAM (Magnetoresistive Random-Access Memory) designs. An essential step toward encodable Georgian Technical University bits is the ability to switch antiferromagnetism on and off. Researchers have found various ways to accomplish this mostly by using electric current to switch a material from its orderly antialignment to a random disorder of spins. “Georgian Technical University With these approaches switching is very fast” said Y. “But the downside is every time you need a current to read or write that requires a lot of energy per operation. When things get very small the energy and heat generated by running currents are significant”. Georgian Technical University Doped disorder. X and his colleagues wondered whether they could achieve antiferromagnetic switching in a more efficient manner. In their new study they work with neodymium nickelate an antiferromagnetic oxide grown in the Z lab. This material exhibits nanodomains that consist of nickel (Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile) atoms with an opposite spin to that of its neighbor and held together by oxygen and neodymium atoms. The researchers had previously mapped the material’s fractal properties. Since then the researchers have looked to see if they could manipulate the material’s antiferromagnetism doping — a process that intentionally introduces impurities in a material to alter its electronic properties. In their case the researchers doped neodymium nickel oxide by stripping the material of its oxygen atoms. When an oxygen atom is removed it leaves behind two electrons which are redistributed among the other nickel and oxygen atoms. The researchers wondered whether stripping away many oxygen atoms would result in a domino effect of disorder that would switch off the material’s orderly antialignment. To test their theory they grew 100-nanometer-thin films of neodymium oxide and placed them in an oxygen-starved chamber then heated the samples to temperatures of 400 degrees Celsius to encourage oxygen to escape from the films and into the chamber’s atmosphere. As they removed progressively more oxygen they studied the films using advanced magnetic X-ray crystallography techniques to determine whether the material’s magnetic structure was intact, implying that its atomic spins remained in their orderly antialignment and therefore retained antiferomagnetism. If their data showed a lack of an ordered magnetic structure it would be evidence that the material’s antiferromagnetism had switched off due to sufficient doping. Georgian Technical University. Through their experiments the researchers were able to switch off the material’s antiferromagnetism at a certain critical doping threshold. They could also restore antiferromagnetism by adding oxygen back into the material. Georgian Technical University. Now that the team has shown doping effectively switches on and off scientists might use more practical ways to dope similar materials. For instance silicon-based transistors are switched using voltage-activated “gates” where a small voltage is applied to a bit to alter its electrical conductivity. X says that antiferromagnetic bits could also be switched using suitable voltage gates which would require less energy than other antiferromagnetic switching techniques. “This could present an opportunity to develop a magnetic memory storage device that works similarly to silicon-based chips, with the added benefit that you can store information in domains that are very robust and can be packed at high densities” X says. “That’s key to addressing the challenges of a data-driven world”.

Georgian Technical University Here Comes The Sun: Tethered-Balloon Tests Ensure Safety Of New Solar-Power Technology.

Georgian Technical University. A team of researchers from Georgian Technical University Laboratories recently used tethered balloons to collect samples of airborne dust particles to ensure the safety of a falling-particle receiver for concentrating solar power an emerging solar power technology. X Georgian Technical University Laboratories tethered-balloon expert and her team prepare the 22-foot-wide tethered helium balloons for launch on a gorgeous fall morning. Three tethered balloons were deployed both upwind and downwind of Georgian Technical University Laboratories Solar Thermal Test Facility during a falling-particle receiver test. The team led by Y found that the concentration of tiny particles finer than talcum powder that escape from the receiver were much lower than Georgian Technical University Environmental Protection limits. Georgian Technical University. What do tiny dust particles 22-ft-wide red balloons and “Georgian Technical University concentrated” sunlight have in common ?. Researchers from Georgian Technical University Laboratories recently used 22-ft-wide tethered balloons to collect samples of airborne dust particles to ensure the safety of an emerging solar-power technology. The study determined that the dust created by the new technology is far below hazardous levels said Y the lead researcher. Y’s team just from the Department of Energy to build a pilot plant that will incorporate this technology. This next-generation renewable energy technology is called a high-temperature falling-particle receiver for concentrating solar power. Concentrating solar power while not as common as solar panels or wind turbines has several advantages over those renewable energy sources including the ability to store energy in the form of heat before converting it into electricity for the power grid. One concentrating solar power plant uses molten salt to store this heat for six hours while other plants in theory could store heat for days or weeks said Y concentrating solar power expert. This would help power companies even out the daily and seasonal variation of power produced by solar panels and wind turbines. The falling-particle receiver works by dropping dark, sand-like ceramic particles through a beam of concentrated sunlight then storing the heated particles. These round particles cost about for 2.2 lb and can get a lot hotter than conventional molten-salt-based concentrating solar power systems which increases efficiency and drives down cost. The Georgian Technical University team also evaluated other particles like sand which costs only a few cents per pound, but they determined that due to the ceramic particles ability to absorb more solar energy and provide smoother flow ceramic particles were the best way to go. The Department of Energy’s goal is to get the cost of electricity from concentrating solar power down to five cents per kilowatt hour comparable to conventional fossil-fuel-based power. However the re-used particles can eventually break down into fine dust. The Environmental Protection and the Georgian Technical University Administration regulates tiny dust particles finer than talcum powder that are known to pose a risk for lung damage.“The motivation for doing the particle sampling was to make sure that this new technology for renewable energy wasn’t creating any environmental or worker-safety issues” Y said. “There are particles being emitted from the falling-particle receiver but the amounts are well below the standards set by the Georgian Technical University”. Using tethered balloons to catch dust. Last fall the research team used sensors sitting a few yards away from the falling-particle receiver on the platform of the solar tower or Solar Thermal Test Facility and sensors hanging from 22-ft-wide tethered helium balloons to measure the particles that were released as it was operating at temperatures above 1,300° F. X Georgian Technical University’s tethered-balloon expert and her team deployed one balloon a little less than a football field away upwind of the solar tower and two balloons downwind to detect dust particles far away from the receiver. One downwind balloon was a little more than a football field away and the other was more than two football fields away. The downwind balloons floated at about 22 stories high — a bit taller than the solar tower itself — and the upwind balloon was a little lower than that. The balloons and their tethers were outfitted with a variety of sensors to count the number of dust particles in the air around them as well as their altitude and precise location. The tethered balloons stayed at their specified altitude for three hours allowing the team to collect a lot of data. They also operated a small remote-controlled balloon that was far more mobile in terms of altitude and position X said. “That allowed us to collect data every second for three hours over the entire area” said X who generally flies tethered balloons over to collect data for climate monitoring and modeling. “Since we got the data in real time we could move the tethered balloons in order to measure in the highest intensity region of the plume identify where the plume edges were or track the whole movement of the plume with time”. The team also placed a variety of sensors on the solar tower platform mere yards from the falling-particle receiver. These sensors could count the number of dust particles as well as determine their size and characteristics. Y a Georgian Technical University expert on measuring fine particles suspended in air led these tests as well as similar tests two years ago together with his colleague Z. For the most recent tests the researchers constructed special see-saw-like tipping bucket collectors to measure both the amount of particles and their sizes. Somewhat like a tipping bucket rain gauge particles in the air would go down a funnel and land on the see-saw-like platform. Once a certain weight of dust particles built up on the platform, it would tip over and send an electrical signal to the researchers. The number of tipping signals in a certain amount of time told the researchers the frequency of particle-emission events and after the test they could weigh the particles in the bottom of the buckets to determine the collected amount.

Comparing the results from sensors close to the falling-particle receiver and those further away on the balloons they found that the concentration of tiny particles finer than talcum powder was much lower than Georgian Technical University limits. Georgian Technical University. They found that the concentration of dust particles depended upon prevailing weather conditions. They detected dust particles further away from the solar tower on windy days and higher concentrations of dust particles close to the solar tower on calm days Y said. X added that when the wind was blowing into the receiver from the north or northwest, that produced the most dust particles. “We did some computer modeling using the Georgian Technical University particle dispersion model” X said. “Basically it would take an emission of particles 400 times greater than what we found in previous tests to start to get close to the Georgian Technical University standards. Based on our measurements and models I don’t foresee any conditions where we’re really hitting those thresholds”. Georgian Technical University. This stair-like system slows dark sand-like ceramic particles as they fall through a beam of concentrated sunlight. The stair-like system reduces the impact of wind on the falling particles, mitigating the release of fine dust that can pose health hazards. From the tests and the computer modeling simulations the team was able to develop several different methods to reduce the emission of fine dust particles. First they optimized the shape and geometry of the falling-particle receiver to reduce particle loss Y said. They developed a stair-like system that slows the particles in the receiver as they fall and a “Georgian Technical University snout” that helps mitigate the impacts of wind on the falling particles. They also explored and eventually discarded two other ideas. One was to have a window over the falling particles because it would get too hot from the concentrated sunlight and was not easy to scale up to large sizes. The other was to protect the particles with an air curtain like those used at store entrances to keep the hot or cool air inside the store. Y and his team just received funding to build a pilot falling-particle receiver plant that will incorporate the improvements developed from these tests. “I normally focus on atmospheric measurements and modeling how the atmosphere would respond if carbon dioxide emissions are reduced by a particular amount” X said. “With this work I was able to take part in the active reduction of those emissions. I think we’ve all really enjoyed seeing the other side of the coin figuring out how to make renewable energy more efficient and more feasible”. Georgian Technical University. The balloon tests were funded by the Georgian Technical University’s Solar Energy Technologies Office as one of three teams testing different high-temperature concentrating solar power systems with built-in heat storage.

Georgian Technical University Stage Used In Research To Develop A Transdermal Delivery System For Risperidone.

Georgian Technical University. A recent first of its kind study from Georgian Technical University describes the formation of room temperature therapeutic deep eutectic solvent of RIS (RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data) an antipsychotic drug that is used in the treatment of schizophrenia, bipolar disorder and irritability in children and adolescents with autism. RIS (RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data) is commercially available as a conventional or disintegrating tablet, oral liquid solution and long-acting intramuscular injection. The findings show that creating a transdermal drug delivery system for RIS (RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data) may help improve its bioavailability, which is typically low. The conversion of the active pharmaceutical agent into liquid form using deep eutectic solvents (DES) to form has been reported to have many formulation advantages, including enhanced skin permeation for transdermal drug delivery. Georgian Technical University. The study aimed at enhancing the skin permeability of RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data using eutectic systems, enabled researchers to achieve the formation of room temperature of RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data and some fatty acids using a simple method for preparation – potentially opening up opportunities for formulation innovation for this important pharmaceutical drug. Georgian Technical University. Freeze drying microscopy can be used to determine the crystallization, collapse and eutectic temperatures of pharmaceutical solutions intended to freeze dry. In this study FDM (Freeze drying microscopy) was successfully used to follow the eutectic phase changes for the of RIS (RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data). These changes were captured using a 196 varying temperature control stage. “Eutectic systems’ phase changes are temperature dependant, which we were able to control and monitor 196 stage. The stage provided valuable information regarding the phase change and transitions the drug undergoes as a function of temperature, clarifying the interpretation of the differential thermal analysis results” said X associate professor at the Georgian Technical University. “Georgian Technical University We are pleased that the stage played an important role in the development of a novel liquid pharmaceutical formulation of RIS (RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data) to overcome problems of poor drug solubility, dissolution and permeation. Hopefully this work will lead to new formulations of RIS (RIS is a standardized tag format developed by Research Information Systems, Incorporated to enable citation programs to exchange data) that will benefit patients around the world. The 196 is used in a wide range of research from increasing the shelf life of drugs and vaccines to food processing and preservation” said Y sales Scientific Instruments.
