Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

Complex evolution and epidemiology of Dobrava-Belgrade hantavirus: definition of genotypes and their characteristics. [PDF]

, 2013
Dobrava-Belgrade virus (DOBV) is a human pathogen that has evolved in, and is hosted by, mice of several species of the genus Apodemus. We propose a subdivision of the species Dobrava-Belgrade virus into four related genotypes – Dobrava, Kurkino ...

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

A Space-Time Study of Hemorrhagic Fever with Renal Syndrome (HFRS) and Its Climatic Associations in Heilongjiang Province, China

Frontiers in Applied Mathematics and Statistics, 2017
Background: Hemorrhagic fever with renal syndrome (HFRS) is highly endemic in China, especially in Heilongjiang province (90% of all reported HFRS cases worldwide occur in China).

Developing a Suitable Anion Exchange Layer Structure for Pure–Water Fed Bipolar Membrane CO2 Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...

Caring for forests between attitude and platitude. Social relationships with nature in industrial forestry in Äänekoski, Finland

People and Nature, EarlyView.
Abstract Forests play a pivotal role in sustainability transitions. This article explores how people's relationships with forests, particularly how they care for or take care of them, shape and reflect broader tendencies and tensions in forest utilization and governance.

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.
