Abstract: Examples are disclosed that relate to using natural language processing (NLP) to determine a recipe for a chemical synthesis described in a text to create a life cycle inventory (LCI). One example provides a method comprising receiving an input of a text from a publication comprising a description of a chemical product, and analyzing the text using NLP to determine a recipe for the chemical synthesis, the recipe comprising and action and action metadata, the action metadata comprising a reactant. The method further discloses obtaining LCI information for the reactant, determining an energy utilized for the action, and creating an estimate of an environmental impact for the product.

Abstract: The present disclosure is directed to a battery that comprise at least one electrochemical cell that comprises a cathode, an anode or an anode current collector and an electrolyte disposed between the cathode and the anode or the current collector, wherein (a) the anode comprises an isotopically enriched metal; (b) the cathode comprises isotopically enriched metal ions; (c) the electrolyte comprises an isotopically enriched metal salt; (d) a combination of (a) and (b); (e) a combination of (a) and (c); (f) a combination of (b) and (c); or (g) a combination of (a), (b) and (c).

Abstract: An improved gas distribution scheme for a multi-wafer radially injected convergent horizontal epitaxial reactor which includes two outer distribution rings, an outer injection ring, an annular susceptor, and a central exhaust tube. The converging path of the gas stream from the outer injection ring into the central exhaust tube compensates for depletion of the reactant gases along the substrate. The injector ring has a large number of evenly spaced diffuser orifices that allow the gas to expand into the growth chamber in a laminar flow pattern. The design is compact, includes the possibility of water cooling of the quartz during deposition, and allows for a resistive bakeout furnace which can be used to etch and clean the reaction chamber between runs.
