Abstract: A chemoenzymatic approach for the synthesis of α-.-heterocyclic ethyl- and phenylacetamides, levetiracetam analogs, is described. Eight nitrile substrates were prepared through the .-alkylation of heterocycles (2-pyrrolidinone, 2-piperidinone, 2-oxopiperazine

Abstract: Lactic acid is an attractive raw material in synthesizing many products. A new method for quantifying glycerol, lactic acid, and the by-products (pyruvaldehyde) obtained in this reaction was developed using high-performance liquid chromatography (HPLC) with a

Abstract: This work investigates the physicochemical properties of a biochar obtained from sugarcane bagasse by torrefaction at four different temperatures (260, 270, 280, and 290 °C), without chemical or physical activation. The biochar was characterized by thermograv

Abstract: Gibbs’ free energy of formation is considered a good guidance in order to describe or predict the phases formation within the standard state; however, many materials are produced out of their equilibrium conditions, and consequently, metastable phases are for
