Electronic Properties Modulation of NiFe-based Nanoalloy by Introducing Cu and P for Faster Oxygen Evolution Reaction Kinetics

, 2023
NiFe-based structures are well known for their high Oxygen Evolution Reaction (OER) activity. But, over time, because of Fe dissolution from these structures, activity and stability decreases gradually.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Tracking the correlation between spintronic structure and oxygen evolution reaction mechanism of cobalt-ruthenium-based electrocatalyst

Nature Communications
Regulating the spintronic structure of electrocatalysts can improve the oxygen evolution reaction performance efficiently. Nonetheless, the effects of tuning the spintronic structure for the oxygen evolution reaction mechanisms have rarely been discussed.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Coffee waste-derived porous carbon for hydrogen and oxygen evolution reaction

Chemical Physics Impact, 2023
Porous carbon was synthesized from coffee waste for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The coffee waste was carbonized at 600 °C for 2 hrs and activated at 500, 600, and 700 °C, respectively. The activated coffee waste
