Ordered modulation of electronic structure for efficient alkaline hydrogen oxidation

open access: yesFlexMat, EarlyView.
We developed imc‐RuGa/hp‐hCN catalyst using in situ elastic spatial confinement method. This catalyst exhibits superior performance for the alkaline HOR, maintaining stable operation for 600 h at a 0.05 V versus RHE working voltage in 0.1 M KOH. It achieved 13 times greater mass activity than commercial PtRu/C.

Lifetime of the Gas Evolution Electrode of the Zn–H2 Storage System

open access: yesFuel Cells, EarlyView.
ABSTRACT A novel electrically chargeable galvanic system is presented that efficiently stores energy in the form of zinc and releases hydrogen and electricity upon discharge. In this concept, oxygen is released at the gas electrode during charging, and zinc oxide is reduced to metallic zinc at the counter electrode.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Characterization of long‐term survivors with liver metastases from uveal melanoma diagnosed between 2005 and 2021

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Liver metastasis is an indicator of life expectancy for patients with advanced uveal melanoma (UM). Data on anticipated survival time following the diagnosis of liver metastasis, however, is lacking. The present study analyzed long‐term survival among UM patients who lived three or more years after liver metastases were diagnosed.
