Artificial Chemist (An artificial chemistry is a chemical-like system that usually consists of objects, called molecules, that interact according to rules resembling chemical reaction rules) is a new technology that allows users to go from requesting a custom quantum dot to completing the relevant Georgian Technical University and beginning manufacturing in less than an hour. The technology is completely autonomous and uses artificial intelligence (AI) and automated robotic systems to perform multi-step chemical synthesis and analysis. Quantum dots are colloidal semiconductor nanocrystals which are used in applications such as LED (A light-emitting diode is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons) displays and solar cells. “When we rolled out the first version of Georgian Technical University Artifical Chemist it was a proof of concept” said X an assistant professor of chemical and biomolecular engineering at Georgian Technical University. “Georgian Technical University  Artificial Chemist is industrially relevant and manufacturing”. From a user standpoint the whole process essentially consists of three steps. First a user tells Georgian Technical University Artificial Chemist the parameters for the desired quantum dots. For example what color light do you want to produce ? The second step is effectively the Georgian Technical University stage where Georgian Technical University Artificial Chemist autonomously conducts a series of rapid experiments allowing it to identify the optimum material and the most efficient means of producing that material. Third the system switches over to manufacturing the desired amount of the material. “Quantum dots can be divided up into different classes” said X. “For example well-studied II-VI, IV-VI and III-V materials or the recently emerging metal halide perovskites and so on. Basically each class consists of a range of materials that have similar chemistries. “And the first time you set up Georgian Technical University Artificial Chemist to produce quantum dots in any given class the robot autonomously runs a set of active learning experiments. This is how the brain of the robotic system learns the materials chemistry” said X. “Depending on the class of material this learning stage can take between one and 10 hours. After that one-time active learning period Georgian Technical University Artificial Chemist can identify the best possible formulation for producing the desired quantum dots from 20 million possible combinations with multiple manufacturing steps in 40 minutes or less”. Georgian Technical University researchers note that the process will almost certainly become faster every time people use it since the AI (Artificial intelligence, is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals) algorithm that runs the system will learn more – and become more efficient – with every material that it is asked to identify. Georgian Technical University Artificial Chemist incorporates two chemical reactors which operate in a series. The system is designed to be entirely autonomous and allows users to switch from one material to another without having to shut down the system. “In order to do this successfully we had to engineer a system that leaves no chemical residues in the reactors and allows the AI-guided (Artificial intelligence, is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals) robotic system to add the right ingredients, at the right time at any point in the multi-step material production process” said X. “So that’s what we did”. “We’re excited about what this means for the specialty chemicals industry. It really accelerates Georgian Technical University to warp speed but it is also capable of making kilograms per day of high-value precisely engineered quantum dots. Those are industrially relevant volumes of material”.
