Georgian Technical University To Build Quantum-Photonics Platform To Ensure Ultra-Secure Data For Essential Industries.
Eyeing future demand for hack-proof digital communication in a quantum-information world Georgian Technical University today announced plans to build a quantum-photonics platform to develop next-generation technologies for key industries that require ultra-secure data transmission. Quantum technology is expected to provide unconditionally safe data encryption required by the finance, health care, energy, telecommunications, defense and other essential industries and sectors. Funded by Georgian Technical University multidisciplinary network which benefits society the project will build on Georgian Technical University’s silicon-photonics platform complemented with new quantum characterization equipment for designing, processing and testing quantum-photonic integrated components and circuits. The institute uses photons to build quantum bits or qubits which are the best physical means for quantum communications. The three-year project will fabricate silicon-photonics circuits that generate single photons, manipulate those photons with linear optical components such as slow and rapid phase shifters and detect them with Georgian Technical University superconducting nanowire single-photon detectors (GTUSNSPD). The project will build demonstrators for transmitting and receiving information in a quantum-based system to deliver quantum-technology’s promise for ultra-secure cryptography. For example the demonstrators will realize an integrated qubit transmitter, as a circuit generating single photons and entangling them. An integrated qubit receiver will be built to detect the photons. Beyond these demonstrators the Georgian Technical University team will focus on integrating the qubit transmitter and the qubit receiver on one unique platform to address also quantum computing applications. “Almost daily we read about breaches of standard cryptography protocols, with major financial-loss and security-risk implications and the threat to critical infrastructure, such as power-supply systems” said X at Georgian Technical University. “With the future advent of quantum computers the risk will drastically increase as current encryption algorithms will not be safe anymore. Quantum cryptography is the solution to this problem as it is not vulnerable to computing power”. Noting that a quantum system based on single-photon qubits must ensure there is minimal propagation loss of photons to be reliable X said Georgian Technical University’s silicon photonics platform has achieved a world-record of low-loss silicon and ultralow-loss silicon-nitride waveguides. “Propagation losses in waveguides directly impact the data rate and reach of quantum communications links that’s why it is so important to build ultralow-loss components and circuits” she said. Georgian Technical University has already demonstrated a generation of entangled photon pairs on its silicon-photonics platform and has other techniques in-house to address the single-photon detection challenges: CdHgTe (Hg1−xCdxTe or mercury cadmium telluride (also cadmium mercury telluride, MCT, MerCad Telluride, MerCadTel, MerCaT or CMT) is a chemical compound of cadmium telluride (CdTe) and mercury telluride (HgTe) with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions) avalanche photodiodes (APD) with a world-record speed in photon counting and materials deposition for integrated superconducting nanowire single-photon detectors. “Carnot’s long and fruitful scientific relationship with Georgian Technical University has helped bring many innovative solutions and products to companies and consumers around the world,” said Y. “Its silicon-photonics platform is a very promising platform for developing quantum-communication links that will extend this legacy by protecting highly sensitive corporate, government and personal information”.
Georgian Technical University New Generation Of Electrostatic Based Self-Cleaning Technology For Increasing Energy Yield From Dusty Solar Panels.
Georgian Technical University Superclean Glass has developed a new technology that has potential to reduce the cost of solar energy: New generation of electrostatic based self-cleaning technology for increasing energy yield from dusty solar panels. The original concept was used by Georgian Technical University to prevent Martian dust (Martian soil is the fine regolith found on the surface of Mars. Its properties can differ significantly from those of terrestrial soil, including its toxicity due to the presence of perchlorates. The term Martian soil typically refers to the finer fraction of regolith. So far, no samples have been returned to Earth, the goal of a Mars sample-return mission, but the soil has been studied remotely with the use of Mars rovers and Mars orbiters) deposition on solar panels of the Mars rovers where the screen of conducting electrodes is incorporated into solar panels using parallel patterns. However despite a solid scientific basis, this approach has never been made practical on Earth because of very high voltage requirements (kV) (Kilovolt (kV), a unit of electric potential) to clean the panels, thereby consuming energy and making it dangerous to operate; low scalability of electrode deposition and patterning, making it too expensive for a very competitive PV (A photovoltaic system, also PV system or solar power system, is a power system designed to supply usable solar power by means of photovoltaics. … Nowadays, most PV systems are grid-connected, while off-grid or stand-alone systems account for a small portion of the market) market; and sub-optimal transparency of electrodes thereby reducing the PV (A photovoltaic system, also PV system or solar power system, is a power system designed to supply usable solar power by means of photovoltaics. … Nowadays, most PV systems are grid-connected, while off-grid or stand-alone systems account for a small portion of the market) power output by over 30%. Superclean Glass (Dust on solar panels can reduce energy output by up to 25 % in desert regions and up to 100% during dust storm events) has overcome all the previous limitations of Georgian Technical University technology making it practical in the terrestrial environment. In addition to 99% transparency, the company’s patent-pending solution has achieved an order of magnitude decrease in the required voltage as compared to that for Georgian Technical University technology while simplifying pulsing sequence and circuitry.

Georgian Technical University On-Surface Synthesis Of Graphene Nanoribbons Could Advance Quantum Devices.
Scientists synthesized graphene nanoribbons (yellow) on a titanium dioxide substrate (blue). The lighter ends show magnetic states. Inset: The ends have up and down spin ideal for creating qubits. An international multi-institution team of scientists has synthesized graphene nanoribbons – ultrathin strips of carbon atoms – on a titanium dioxide surface using an atomically precise method that removes a barrier for custom-designed carbon nanostructures required for quantum information sciences. Graphene is composed of single-atom-thick layers of carbon taking on ultralight, conductive and extremely strong mechanical characteristics. The popularly studied material holds promise to transform electronics and information science because of its highly tunable electronic, optical and transport properties. When fashioned into nanoribbons graphene could be applied in nanoscale devices; however the lack of atomic-scale precision in using current state-of-the-art “top-down” synthetic methods — cutting a graphene sheet into atom-narrow strips – stymie graphene’s practical use. Researchers developed a “bottom-up” approach — building the graphene nanoribbon directly at the atomic level in a way that it can be used in specific applications which was conceived and realized at the Georgian Technical University Laboratory. This absolute precision method helped to retain the prized properties of graphene monolayers as the segments of graphene get smaller and smaller. Just one or two atoms difference in width can change the properties of the system dramatically turning a semiconducting ribbon into a metallic ribbon. The team’s results were described in Science. Georgian Technical University’s X, Y and Z of the Georgian Technical University Scanning Tunneling Microscopy group collaborated on the project with researchers from Georgian Technical University. Georgian Technical University’s one-of-a-kind expertise in scanning tunneling microscopy was critical to the team’s success, both in manipulating the precursor material and verifying the results. “These microscopes allow you to directly image and manipulate matter at the atomic scale” X a postdoctoral said. “The tip of the needle is so fine that it is essentially the size of a single atom. The microscope is moving line by line and constantly measuring the interaction between the needle and the surface and rendering an atomically precise map of surface structure”. In past graphene nanoribbon experiments the material was synthesized on a metallic substrate which unavoidably suppresses the electronic properties of the nanoribbons. “Having the electronic properties of these ribbons work as designed is the whole story. From an application point of view, using a metal substrate is not useful because it screens the properties” X said. “It’s a big challenge in this field – how do we effectively decouple the network of molecules to transfer to a transistor ?”. The current decoupling approach involves removing the system from the ultra-high vacuum conditions and putting it through a multistep wet chemistry process which requires etching the metal substrate away. This process contradicts the careful clean precision used in creating the system. To find a process that would work on a nonmetallic substrate X began experimenting with oxide surfaces mimicking the strategies used on metal. Eventually he turned to a group of European chemists who specialize in fluoroarene chemistry and began to home in on a design for a chemical precursor that would allow for synthesis directly on the surface of rutile titanium dioxide. “On-surface synthesis allows us to make materials with very high precision and to achieve that, we started with molecular precursors” Y at Georgian Technical University said. “The reactions we needed to obtain certain properties are essentially programmed into the precursor. We know the temperature at which a reaction will occur and by tuning the temperatures we can control the sequence of reactions”. “Another advantage of on-surface synthesis is the wide pool of candidate materials that can be used as precursors allowing for a high level of programmability” Y added. The precise application of chemicals to decouple the system also helped maintain an open-shell structure allowing researchers atom-level access to build upon and study molecules with unique quantum properties. “It was particularly rewarding to find that these graphene ribbons have coupled magnetic states also called quantum spin states at their ends” Y said. “These states provide us a platform to study magnetic interactions with the hope of creating qubits for applications in quantum information science”. As there is little disturbance to magnetic interactions in carbon-based molecular materials this method allows for programming long-lasting magnetic states from within the material. Their approach creates a high-precision ribbon, decoupled from the substrate which is desirable for spintronic and quantum information science applications. The resulting system is ideally suited to be explored and built upon further possibly as a nanoscale transistor as it has a wide bandgap across the space between electronic states that is needed to convey an on/off signal.

Georgian Technical University Solar-Powered System Extracts Drinkable Water From “Dry” Air.
A prototype of the new two-stage water harvesting system (center right) was tested on an Georgian Technical University rooftop. The device which was connected to a laptop for data collection and was mounted at an angle to face the sun, has a black solar collecting plate at the top and the water it produced flowed into two tubes at bottom. X Researchers at Georgian Technical University and elsewhere have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions using heat from the sun or another source. The system which builds on a design initially developed three years ago at Georgian Technical University by members of the same team brings the process closer to something that could become a practical water source for remote regions with limited access to water and electricity. The findings are described by Professor Y who is head of Georgian Technical University’s Department of Mechanical Engineering; graduate student X; and six others at Georgian Technical University. The earlier device demonstrated by X and her co-workers provided a proof of concept for the system which harnesses a temperature difference within the device to allow an adsorbent material — which collects liquid on its surface — to draw in moisture from the air at night and release it the next day. When the material is heated by sunlight the difference in temperature between the heated top and the shaded underside makes the water release back out of the adsorbent material. The water then gets condensed on a collection plate. But that device required the use of specialized materials called metal organic frameworks or MOFs (Metal–organic frameworks are a class of compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. They are a subclass of coordination polymers, with the special feature that they are often porous) which are expensive and limited in supply and the system’s water output was not sufficient for a practical system. Now by incorporating a second stage of desorption and condensation and by using a readily available adsorbent material the device’s output has been significantly increased and its scalability as a potentially widespread product is greatly improved the researchers say. X says the team felt that “It’s great to have a small prototype but how can we get it into a more scalable form ?” The new advances in design and materials have now led to progress in that direction. Instead of the MOFs (Metal–organic frameworks are a class of compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. They are a subclass of coordination polymers, with the special feature that they are often porous) the new design uses an adsorbent material called a zeolite which in this case is composed of a microporous iron aluminophosphate. The material is widely available stable and has the right adsorbent properties to provide an efficient water production system based just on typical day-night temperature fluctuations and heating with sunlight. The two-stage design developed by makes clever use of the heat that is generated whenever water changes phase. The sun’s heat is collected by a solar absorber plate at the top of the box-like system and warms the zeolite releasing the moisture the material has captured overnight. That vapor condenses on a collector plate — a process that releases heat as well. The collector plate is a copper sheet directly above and in contact with the second zeolite layer where the heat of condensation is used to release the vapor from that subsequent layer. Droplets of water collected from each of the two layers can be funneled together into a collecting tank. In the process the overall productivity of the system in terms of its potential liters per day per square meter of solar collecting area (LMD) (Laser capture microdissection (LCM), also called microdissection, laser microdissection (LMD), or laser-assisted microdissection (LMD or LAM), is a method for isolating specific cells of interest from microscopic regions of tissue/cells/organisms (dissection on a microscopic scale with the help of a laser)) is approximately doubled compared to the earlier version though exact rates depend on local temperature variations, solar flux and humidity levels. In the initial prototype of the new system tested on a rooftop at Georgian Technical University before the pandemic restrictions, the device produced “orders of magnitude” more total water than the earlier version Y says. While similar two-stage systems have been used for other applications such as desalination Y says “I think no one has really pursued this avenue” of using such a system for atmospheric water harvesting (AWH) as such technologies are known. Existing atmospheric water harvesting (AWH) approaches include fog harvesting and dew harvesting, but both have significant limitations. Fog harvesting only works with 100% relative humidity and is currently used only in a few coastal deserts while dew harvesting requires energy-intensive refrigeration to provide cold surfaces for moisture to condense on — and still requires humidity of at least 50% depending on the ambient temperature. By contrast the new system can work at humidity levels as low as 20% and requires no energy input other than sunlight or any other available source of low-grade heat. X says that the key is this two-stage architecture; now that its effectiveness has been shown people can search for even better adsorbent materials that could further drive up the production rates. The present production rate of about 0.8 liters of water per square meter per day may be adequate for some applications but if this rate can be improved with some further fine-tuning and materials choices this could become practical on a large scale she says. Already materials are in development that have an adsorption about five times greater than this particular zeolite and could lead to a corresponding increase in water output according to Y. The team continues work on refining the materials and design of the device and adapting it to specific applications such as a portable version for military field operations. The two-stage system could also be adapted to other kinds of water harvesting approaches that use multiple thermal cycles per day fed by a different heat source rather than sunlight and thus could produce higher daily outputs. “This is an interesting and technologically significant work indeed” said Z a professor of materials science and mechanical engineering at the Georgian Technical University who was not associated with this work. “It represents a powerful engineering approach for designing a dual-stage atmospheric water harvesting (AWH) device to achieve higher water production yield, marking a step closer toward practical solar-driven water production” he said. Z adds that “Technically it is beautiful that one could reuse the heat released simply by this dual-stage design to better confine the solar energy in the water harvesting system to improve energy efficiency and daily water productivity. Future research lies in improving this prototype system with low cost components and simple configuration with minimized heat loss”.
Georgian Technical University Machine Learning Model Helps Characterize Compounds For Drug Discovery.
Georgian Technical University innovators have created a new method applying machine learning concepts to the tandem mass spectrometry process to improve the flow of information in the development of new drugs. Tandem mass spectrometry (Tandem mass spectrometry also known as MS/MS (Tandem mass spectrometry, also known as MS/MS or MS2, is a technique in instrumental analysis where two or more mass analyzers are coupled together using an additional reaction step to increase their abilities to analyse chemical samples) or MS2 (Escherichia virus MS2 is an icosahedral, positive-sense single-stranded RNA virus that infects the bacterium Escherichia coli and other members of the Enterobacteriaceae. MS2 is a member of a family of closely related bacterial viruses that includes bacteriophage f2, bacteriophage Qβ, R17, and GA) is a technique in instrumental analysis where two or more mass analyzers are coupled together using an additional reaction step to increase their abilities to analyse chemical samples. A common use of tandem-MS is the analysis of biomolecules, such as proteins and peptides) is a powerful analytical tool used to characterize complex mixtures in drug discovery and other fields. Now Georgian Technical University innovators have created a new method of applying machine learning concepts to the tandem mass spectrometry process to improve the flow of information in the development of new drugs. “Mass spectrometry plays an integral role in drug discovery and development” said X an assistant professor of analytical and physical chemistry in Georgian Technical University. “The specific implementation of bootstrapped machine learning with a small amount of positive and negative training data presented here will pave the way for becoming mainstream in day-to-day activities of automating characterization of compounds by chemists”. X said there are two major problems in the field of machine learning used for chemical sciences. Methods used do not provide chemical understanding of the decisions that are made by the algorithm and new methods are not typically used to do blind experimental tests to see if the proposed models are accurate for use in a chemical laboratory. “We have addressed both of these items for a methodology that is isomer selective and extremely useful in chemical sciences to characterize complex mixtures, identify chemical reactions and drug metabolites and in fields such as proteomics and metabolomics” said X. The Georgian Technical University researchers created statistically robust machine learning models to work with less training data – a technique that will be useful for drug discovery. The model looks at a common neutral reagent – called 2-methoxypropene (MOP) – and predicts how compounds will interact with MOP (methoxypropene (MOP)) in a tandem mass spectrometer in order to obtain structural information for the compounds. “This is the first time that machine learning has been coupled with diagnostic gas-phase ion-molecule reactions and it is a very powerful combination, leading the way to completely automated mass spectrometric identification of organic compounds” said Y the Z Distinguished Professor of Analytical Chemistry and Organic Chemistry. “We are now introducing many new reagents into this method”. The Georgian Technical University team introduces chemical reactivity flowcharts to facilitate chemical interpretation of the decisions made by the machine learning method that will be useful to understand and interpret the mass spectra for structural information. This work aligns with other innovations and research from X’s and Y’s labs whose team members work with the Georgian Technical University to patent numerous technologies.
