Abstract: The disclosure presents an apparatus and method for measuring viscosity of a lubricating oil. The apparatus has a piezo-resistive cantilever sensor for sensing a first oil viscosity parameter. The sensor has a cantilever having a pressure receiving portion for receiving pressure exerted by the lubricating oil as the lubricating oil comes into contact with the pressure receiving portion. The cantilever also has first and second resistive portions in electrical communication with a first lead and a second lead, respectively, which are in electrical communication with an electrical circuit amplification element, for creating an output signal indicative of a change in the resistive characteristics of the first and second resistive portions of the cantilever as the lubricating oil comes into contact with the pressure receiving portion. The output signal can be used for determining oil viscosity.

Abstract: A process is described to prepare a single enantiomer of an amino acid from its opposite enantiomer or from a racemic mixture, using an oxidase biocatalyst and a supported metal catalyst in separate, sequential reactions in water. The process can be operated in batch or continuous mode.

Abstract: A process for producing high yields of enantioselective amino acids and chiral amines by reacting a keto acid or ketone and an amino acid donor in the presence of a transaminase biocatalyst to produce a keto acid by-product and an amino acid or amine product. Further reacting the keto acid by-product with a peroxide to increase the yield of additional amino acid or amine product.
