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 ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies
Advanced Engineering Materials, EarlyView.Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Direct deoxygenative borylation of carboxylic acids
Nature Communications, 2021 Converting a carboxylic acid into a boronic acid, which makes a useful chemical handle from a feedstock chemical, currently relies on decarboxylation and requires metal catalysts and prior functionalization.

Advanced Engineering Materials, EarlyView.The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Inhibitors of Bacterial \u3cem\u3eN\u3c/em\u3e-succinyl-L,L-diaminopimelic Acid Desuccinylase (DapE) and Demonstration of in vitro Antimicrobial Activity [PDF]
, 2009 The dapE-encoded N-succinyl-L,L-diaminopimelic acid desuccinylase (DapE) is a critical bacterial enzyme for the construction of the bacterial cell wall. A screen biased toward compounds containing zinc-binding groups (ZBG’s) including thiols, carboxylic ...

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 ...

Advanced Engineering Materials, EarlyView.This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion
