LowCOST‐HSQC Variants for Fast‐Pulsing High ω1‐Resolved 2D Experiments

Magnetic Resonance in Chemistry, Volume 64, Issue 7, Page 655-665, July 2026.
The LowCOST‐HSQC is a sensitivity‐enhanced HSQC version that retains unused proton polarization for subsequent scans in correlations to low natural abundance nuclei like 13C or 15N. Together with fast polarization distribution via isotropic mixing, it allows the acquisition of fast‐pulsing 2D experiments.

Iron Complexes With Proteins, Carbohydrates, and Maillard Products in Dairy Systems: Implication for Fortification, Bioavailability, and Product Functionality

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT The global prevalence of iron (Fe) deficiency anemia (IDA) continues to pose major public health challenges, necessitating the development of effective fortification strategies. Dairy‐based systems are promising vehicles for Fe fortification and delivery due to their widespread consumption and nutritional value, although their complex matrix ...

Enhanced Electrochemical Oxidation of Ethanol Over Nickel Foam Supported Pt–Au Alloy Electrode

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Nickel foam‐supported strategically engineered Pt–Au alloy with a Pt‐enriched surface and Au‐rich bulk promotes strong electronic and bifunctional synergies. This structural design drives highly efficient ethanol electro‐oxidation, proceeding through an acetaldehyde intermediate to produce acetate.

Innovating Electrosynthesis From Metal Electrodeposition to Organic Chemistry: Deep Eutectic Solvents as Efficient and Sustainable Media

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
This review analyzes deep eutectic solvents (DESs) as efficient media for both organic and inorganic electrosynthesis. The improvements in terms of synthetic opportunities and sustainability are discussed, by exploring the multiple roles of DESs as solvents, electrolytes, and promoters, enabling effective and selective electrosynthesis under mild and ...

INFLUENCE OF ETHANOL AND ITS FIRST METHABOLITE ACETALDEHYDE ON THE CENTRAL NERVOUS SYSTEM

Zdravniški Vestnik, 2009
Background Ethanol, a legal drug, is a big social problem in our country. First of all because of addiction development and also due to consequences of the chronic alcoholism. Ethanol effects to almost all organ systems.

Bridging Liquid and Gas Phase Catalysis for Abiotic CO2 Conversion to Prebiotic Organics Over Mesoporous Silica‐Supported Ni–Co Catalysts

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Under simulated hydrothermal vent conditions, Ni⋅Co bimetallic catalysts supported on silica convert CO2 and H2O into key metabolites such as formate, methanol, and ethanol. Water plays a critical role in CO2 adsorption and product selectivity, shaping catalytic performance across both liquid and gas phases.

Enantioselective Synthesis of Lactic Acid From CO2 Using a Novel Pyruvate Decarboxylase in a Scalable Biocatalytic Cascade

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We report a scalable biocatalytic cascade that converts CO2 and acetaldehyde to pyruvate via a newly characterized pyruvate decarboxylase, followed by stereoselective reduction to lactic acid. The system enables fully switchable enantioselectivity using either L‐ or D‐lactate dehydrogenases.

Techno-economic Analysis and Life Cycle Assessment of Renewable Acetaldehyde from Sugarcane Ethanol

Chemical Engineering Transactions
Acetaldehyde has been historically synthesized from ethanol via oxidation. However, since the 1960s, the cost of feedstock and conversion process has gradually driven manufacturers to prefer the liquid-phase oxidation of ethylene.
