Impact of pH and Composition of Phosphovanadomolybdate Anionic Catholytes on the Performance of Redox Flow Polymer Electrolyte Fuel Cells

Electrochemistry
A H15P3V6Mo18O84 aqueous solution containing phosphovanadomolybdate anions such as [PV3Mo9O40]6− and [PV2Mo10O40]5− were applied to a catholyte of redox flow polymer electrolyte fuel cells (PEFCs).

Reciprocal Sum Expression for Steady-state Kinetics —Enzyme Reactions and Voltammetry—

Electrochemistry, 2022
Steady-state experiments are often conducted to understand complicated cases in chemistry, since the kinetics does not have a time valuable and allows simple modeling of the reactions.

Asgard archaea capable of anaerobic hydrocarbon cycling

Nature Communications, 2019
Large reservoirs of natural gas in the oceanic subsurface sustain complex communities of anaerobic microbes, including archaeal lineages with potential to mediate oxidation of hydrocarbons such as methane and butane. Here we describe a previously unknown

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

FEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Efficient 1,4-addition of α-substituted fluoro(phenylsulfonyl)methane derivatives to α,β-unsaturated compounds

Beilstein Journal of Organic Chemistry, 2008
The 1,4-addition of a monofluoromethyl nucleophile to a variety of α,β-unsaturated compounds has been achieved under mild conditions using either phosphines or potassium carbonate at room temperature.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

FEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

C(sp3)–heteroatom bond formation by iron-catalyzed soft couplings

Communications Chemistry
Carbon–heteroatom bonds are of great importance due to their prevalence in pharmaceuticals, agrochemicals, materials, and natural products. Despite the effective use of metal-catalyzed cross-coupling reactions between sp2-hybridized organohalides and ...
