Comment on "On the origin of multihole oxygen evolution in haematite photoanodes"

, 2023
The Article1 deals with the mechanism of oxygen evolution reaction (OER) on hematite photoanodes. The authors claimed that the OER rate or photocurrent density has a third-order (or power law) dependence on surface hole density.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

MoS2-nanosheet-decorated C-N/Co4S3 nanorod hybrid as a bifunctional electrocatalyst

Electrochemistry Communications, 2019
A MoS2-nanosheet-decorated C-N/Co4S3 (C-N/Co4S3@MoS2) nanorod with multi-defects was synthesized by using a core-shell zeolitic imidazole framework (ZIF-8@ZIF-67) as the precursor.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Nitrogen Loss and Oxygen Evolution Reaction Activity of Perovskite Oxynitrides

, 2019
Perovskite oxynitride photocatalysts were reported by experiment to evolve small amounts of N2, because of the self-oxidation of nitrogen ions by photogenerated holes.

Lattice oxygen evolution in rutile Ru(1−x)Ni(x)O2 electrocatalysts

, 2023
Efficient predictive tools for oxygen evolution reaction (OER) activity assessment are vital for rational design of anodes for green hydrogen production. Reaction mechanism prediction represents an important pre-requisite for such catalyst design.
