Valorization of Lignin by Partial Wet Oxidation Using Sustainable Heteropoly Acid Catalysts
Molecules, 2017 The production of carboxylic acids by partial wet oxidation of alkali lignin at elevated temperatures and pressures was studied experimentally. Two different heteropoly acids, phosphotungstic acid (H3PW12O40) and phosphomolybdic acid (H3PMo12O40), were ...

Production of medium-chain carboxylic acids by Megasphaera sp MH with supplemental electron acceptors [PDF]
, 2016 Background: C5-C8 medium-chain carboxylic acids are valuable chemicals as the precursors of various chemicals and transport fuels. However, only a few strict anaerobes have been discovered to produce them and their production is limited to low ...

Influence of ligand shape and steric hindrance on the composition of the nanocrystal ligand shell [PDF]
, 2015 Organic ligands play a key role in the synthesis of colloidal semiconductor nanocrystals or quantum dots. Generally they consist of a functional group and an aliphatic chain, with carboxylic acids, thiols and phosphonic acids as typical examples.

Structures of carboxylic acid reductase reveal domain dynamics underlying catalysis
Nature Chemical Biology, 2017 Carboxylic acid reductase (CAR) catalyzes the ATP- and NADPH-dependent reduction of carboxylic acids to the corresponding aldehydes. The enzyme is related to the non-ribosomal peptide synthetases, consisting of an adenylation domain fused via a peptidyl ...
