Bi-functional Oxygen Electrocatalysts Using Mixed-Metal Tungsten-Nitrides in Alkaline Media

Electrochemistry, 2022
Transition metal-tungsten nitrides (CrWN2, MnWN2, FeWN2, Co3W3N, Ni2W3N) could be synthesized and electrocatalytic properties on electrochemical oxygen reduction and evolution reactions were examined.

PdMo bimetallene for oxygen reduction catalysis

Nature, 2019
The efficient interconversion of chemicals and electricity through electrocatalytic processes is central to many renewable-energy initiatives. The sluggish kinetics of the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER)1-4 has long posed one of the biggest challenges in this field, and electrocatalysts based on expensive ...

Carbon for the oxygen reduction reaction: A defect mechanism

, 2015
We demonstrate a new defect mechanism of carbons for the oxygen reduction reaction (ORR). It is predicted by the first principles calculations that a type of 585 defect on graphene (G585) is more effective than N-doping for the ORR, and our experimental ...

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.

Characterization of Zeolitic Imidazolate Framework–derived Polyhedral Carbonaceous Material and its Application to Electrocatalyst for Oxygen Reduction Reaction

International Journal of Electrochemical Science, 2016
A porous carbonaceous material is synthesized by direct carbonization of zeolitic imidazolate framework-67 (ZIF-67). A series of analytical tools such as scanning/transmission electron microscopy, gas chromatography/mass spectroscopy, thermogravimetric ...

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.

Three Toxic Gases Meet in the Mitochondria

Frontiers in Physiology, 2015
The rationale of the study was two-fold : (i) develop a functional synthetic model of the Cytochrome c oxidase (CcO) active site, (ii) use it as a convenient tool to understand or predict the outcome of the reaction of CcO with ligands (physiologically ...
