Release and Formation of Oxidation-Related Aldehydes during Wine Oxidation.
Twenty-four Spanish wines were subjected to five consecutive cycles of air saturation at 25 °C. Free and bound forms of carbonyls were measured in the initial samples and after each saturation.

Rigid Fluorescent Indacenetetraone‐Based Semiconducting Polymers via Knoevenagel Condensation
New donor–acceptor polymers prepared by Knoevenagel condensation of indacenedithiophene‐ and indacenedifuran‐based aldehydes reveal an exceptionally rigid backbone, which is manifested in the remarkably narrow absorption and emission bands in red to near‐infrared region.

Gas-liquid chromatography of 2-chloroethyl esters using a detector specific for halogens
The gas-liquid chromatography of 2-chloroethyl derivatives of short- and long-chain monocarboxylic acids, and of short-chain dicarboxylic acids and aldehydes has been studied with a dual-flame ionization detector that provided simultaneous records of the

Modeling of the formation of short-chain acids in propane flames [PDF]
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Research of Mineral Adsorbents Application for Water-alcohol Solutions Purification in Technology of Alcoholic Beverages [PDF]
The possibility of using natural mineral adsorbents - clinoptilolite and schungite - in the adsorption purification of water-alcohol solutions of different concentrations was studied using the example of impurities of ethanol of acetaldehyde and ethyl ...

Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.
