The chemical coupling between moist CO oxidation and gas-phase potassium sulfation (open access)

The chemical coupling between moist CO oxidation and gas-phase potassium sulfation

Article discusses how the chemical coupling between moist CO oxidation and transformation of gaseous potassium salts (KCl or KOH) in the presence and absence of SO2 was investigated experimentally and through chemical kinetic modeling. Analysis of the calculations indicates that sulfation pathways in the model involving KOSO3 contribute to the overprediction, but both the thermodynamic properties and rate constants in the model involve significant uncertainties and more work is required to resolve the discrepancy.

Comparative Proteomics Analysis Reveals Unique Early Signaling Response of Saccharomyces cerevisiae to Oxidants with Different Mechanism of Action (open access)

Comparative Proteomics Analysis Reveals Unique Early Signaling Response of Saccharomyces cerevisiae to Oxidants with Different Mechanism of Action

This article uses a discovery driven comparative proteomics analysis to reveal unique early signaling response of the yeast Saccharomyces cerevisiae on the proteome level to oxidants with a different mechanism of action as early as 3 min after treatment with four oxidants, namely H₂O₂, cumene hydroperoxide (CHP), and menadione and diamide, when protein abundances were compared using label-free quantification relying on a high-resolution mass analyzer (Orbitrap).

Computational study of the gas-phase reactions of sulfuric acid with OH(ΠJ), O(3PJ), Cl(2P) and O(1D2) radicals (open access)

Computational study of the gas-phase reactions of sulfuric acid with OH(ΠJ), O(3PJ), Cl(2P) and O(1D2) radicals

This article is about how rate coefficients for reactions of H2SO4 with OH, O(3P) and Cl radicals over 160–298 K were estimated computationally. The authors propose kOH = 8.5 × 10-14 exp(-50 K/T), kO = 1.1 × 10-12 exp(-5012 K/T) and kCl = 3.1 × 10-9 exp(-3314 K/T) cm3 molecule-1 s−1.

The Crucial Role of Solvation Forces in the Steric Stabilization of Nanoplatelets (open access)

The Crucial Role of Solvation Forces in the Steric Stabilization of Nanoplatelets

Article says that the steric stability of inorganic colloidal particles in an apolar solvent is usually described in terms of the balance between three contributions: the van der Waals attraction, the free energy of mixing, and the ligand compression. The authors demonstrate that for sufficiently large nanoplatelets, solvation forces are proportional to the interacting facet area, and their strength is intrinsically tied to the softness of the ligand shell.

Fatty acid amide hydrolase and 9-lipoxygenase  modulate cotton seedling growth by ethanolamide  oxylipin levels (open access)

Fatty acid amide hydrolase and 9-lipoxygenase modulate cotton seedling growth by ethanolamide oxylipin levels

Article asserts that polyunsaturated N-acylethanolamines (NAEs) can be hydrolyzed by fatty acid amide hydrolase (FAAH) or oxidized by lipoxygenase (LOX). Altogether, the authors conclude that the growth of cotton seedlings involves fine-tuning of 9-NAE-HOD levels via FAAH-mediated hydrolysis and LOX-mediated production, expanding the mechanistic understanding of plant growth modulation by NAE oxylipins to a perennial crop species.

Molecular signatures in the progression of COVID-19 severity

Authors of the article discuss that to uncover genes and pathways involved in the differential clinical manifestations of COVID-19 they developed a novel gene co-expression network-based pipeline that uses gene expression obtained from different SARS-CoV-2 infected human tissues. Their study shines a new light on genes and their networks (modules) that drive the progression of COVID-19 from moderate to extremely severe condition, which could aid development of new therapeutics to combat COVID-19.
