Abstract: A method for synthesizing cyclic carbonate monomers using carbon dioxide (CO2) is provided. The method also includes combining reagents to synthesize the cyclic carbonate monomer, the reagents including a substrate that is a 1,X-diol, where X is between 2 and 5, a base that is a tertiary amine, a promoter that is a multidentate, bis-tertiary amine base where nitrogens are separated by 2 to 4 carbon atoms, a solvent, and CO2.

Abstract: A reward-based reinforcement learning (RL) computing environment with an RL agent has a goal to discovery new polymers. The RL environment is integrated with a logical optimal action (LOA) framework that includes a logical neural network (LNN). The RL environment and the LOA framework share a user interface that switches between the LOA framework and the RL environment. At the LOA interface, polymer datasets are entered into the LOA framework along with subject matter expert (SME)-defined rules that limit the scope of the information in the datasets. The datasets and the SME-defined rules train the LNN to develop policy rules. Upon training completion, the datasets and the LNN policy rules are input into the RL environment where the RL agent makes reward-based decisions on the information in the datasets that advance the goal. At the RL interface, the SME reviews the RL agent's decisions to eliminate decisions that do not advance the goal.

Abstract: A method of preparing electronically conductive polyaniline that forms a self-supporting dispersion in water is described. The binder-free dispersion was coated on a pair of interdigitated metal electrodes to form a gas sensing layer of a chemical sensor. The chemical sensor utilizes electrochemical impedance spectroscopy (EIS) to detect and characterize a chemical compound in a gaseous state in contact with the sensing layer. Impedance of the sensing layer is measured over a range of alternating current frequencies. The impedance data allows identification and concentration of the chemical compound to be determined when compared to reference impedance data. The analysis of the impedance measurements is adaptable to machine learning.
