Transition-metal selenides in hydrogen and oxygen electrocatalysis

Metals Advances
Transition-metal selenides (TMSes) are attracting increasing interest as electrocatalysts owing to the covalent nature of the metal–Se bond and the polarizable Se sublattice, which collectively reshape charge distribution and adsorption energetics at ...

Missing-linker metal-organic frameworks for oxygen evolution reaction

Nature Communications, 2019
While water splitting electrocatalysis provides a means to store electrical energy as fuel, the water oxidation catalysts typically show low performances.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

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.

Oxygen desorption – Critical step for the oxygen evolution reaction

Current Opinion in Electrochemistry, 2023
The oxygen evolution reaction (OER) has been widely investigated in computational electrocatalysis. Recent studies suggest that the final oxygen desorption step could be rate-limiting, or even inhibiting, for the classical OER mechanism on the benchmark IrO2 electrocatalyst, and a novel reaction mechanism has been proposed circumventing this bottleneck.

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

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
