Carboxylic-acid-passivated metal oxide nanocrystals : ligand exchange characteristics of a new binding motif [PDF]
, 2015 Ligand exchange is central in the processing of inorganic nanocrystals (NCs) and requires understanding of surface chemistry. Studying sterically stabilized HfO2 and ZrO2 NCs using H-1 solution NMR and IR spectroscopy as well as elemental analysis, this ...

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 ...

Photocatalytic direct borylation of carboxylic acids
Nature Communications, 2022 Boronic acids are useful reagents in organic synthesis and thus methods to prepare these compounds under mild conditions are desirable. Here, the authors synthesize boronic acids via photocatalytic decarboxylation of benzoic acids followed by borylation;

Electricity-assisted production of caproic acid from grass [PDF]
, 2017 Background: Medium chain carboxylic acids, such as caproic acid, are conventionally produced from food materials. Caproic acid can be produced through fermentation by the reverse beta-oxidation of lactic acid, generated from low value lignocellulosic ...
