Phase equilibria in binary systems containing acetaldehyde

, 1979
The vapour-liquid equilibrium in binary acetaldehyde-diethyl ether, acetaldehyde-ethanol and acetaldehyde-water systems was measured at the pressure of 101.32 kPa.

Guest Transition Metals in Host Keplerate Nanocapsules as Supramolecular Inorganic Functional Mimics of Monooxygenase Enzymes

Angewandte Chemie, EarlyView.
A Keplerate, an inorganic, porous buckyball was used as a host for copper metal cations ligated by histidine surrogates. Prepared by a simple assembly technique, the guest–host complex was used as a primitive biomimetic model of a monooxygenase enzyme complex, where C─H bonds were electrocatalytically hydroxylated by oxygen under reducing conditions ...

Slow-release L-cysteine capsule prevents gastric mucosa exposure to carcinogenic acetaldehyde : results of a randomised single-blinded, cross-over study of Helicobacter-associated atrophic gastritis [PDF]

, 2017
Introduction: Helicobacter-induced atrophic gastritis with a hypochlorhydric milieu is a risk factor for gastric cancer. Microbes colonising acid-free stomach oxidise ethanol to acetaldehyde, a recognised group 1 carcinogen.

Co‐Delivery of Sustained Release Chondroitinase ABC‐37 With Human iPSC‐Derived Neural Progenitors Promotes Transplant Survival and Functional Recovery in a Rodent Model of Stroke

Advanced Science, EarlyView.
A regenerative strategy for stroke combines human stem cell–derived neural progenitor cells with sustained release of a matrix‐modifying, thermostable chondroitinase ABC‐37 enzyme. In a rat model of stroke, co‐delivery enhanced transplanted cell survival and neuronal differentiation, degraded inhibitory extracellular matrix components, and improved ...

Direct Observation of Radical‐Mediated Oxide‐to‐Alloy Transformation in Solution Under Pulsed Laser Irradiation

Angewandte Chemie, EarlyView.
Time‐resolved in situ x‐ray absorption spectroscopy and DFTB‐based molecular dynamics simulations identify direct hydrogen atom transfer from ethanol to lattice oxygen as the elementary step of laser‐driven reduction in NiCo2O4. While this transfer is facile, the subsequent release of lattice oxygen is entropy‐driven and becomes accessible only at ...

Acetaldehyde exposure alters fibrin polymerization, fibrinolysis, and fibrin network structure in vitro

Research and Practice in Thrombosis and Haemostasis
Background: Fibrin(ogen), the primary structural component of blood clots, plays a critical role in thrombosis and hemostasis. Posttranslational modifications to fibrinogen that occur upon exposure to reactive endogenous metabolites or xenobiotics during

c-Fos immunoreactivity in prefrontal, basal ganglia and limbic areas of the rat brain after central and peripheral administration of ethanol and its metabolite acetaldehyde.

Frontiers in Behavioral Neuroscience, 2013
Considerable evidence indicates that the metabolite of ethanol (EtOH), acetaldehyde, is biologically active. Acetaldehyde can be formed from EtOH peripherally mainly by alcohol dehydrogenase, and also centrally by catalase.

Role of acetaldehyde in alcohol addiction : current evidence and future perspectives [PDF]

, 2011
The effects of alcohol have been widely studied during the past century, corroborating the idea that this tiny chemical compound acts throughout most of our neurotransmitter systems since it is capable of inducing addictive behaviour.

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

Advanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...
