Polymer electrolyte membrane water electrolysis (PEMWE) is regarded as commercial electrochemical water-splitting technology to produce clean and sustainable hydrogen fuel from renewable energy resources. But current PEMWE system requires the noble metal-based metal, such Pt, Ir or Ru, electrocatalysts, which limits large-scale commercialization of PEMWE. Thus, developing cost-effective highly ...

Vapor deposited Cu/Co multilayers with high quality Co-Cu interfaces exhibit significant giant magnetoresistance. These multilayers are sometimes grown using process environments with significant background partial pressures of oxygen, which can impact the quality of film and its properties. Previously we found that oxygen preferentially stabilizes Co/Cu 111 . First principle density functional...

-The magnetic heat capacity of Gol-,MnxC12.2H20 with competing exchange interactions has been observed. A characteristic broad maximum appears around 4.5 K for x = 0.46 : nearly half of the magnetic entropy remains in the temperature region above 4.5 K. These thermal properties are discussed in comparison with other glassy systems.

We document diversity and its distribution within the hyperdiverse Monomorium nigrius Forel group of Australian monsoonal tropics, an unrecognized global centre ant diversity. The includes a single described species, but several distinct morphotypes each with multiple clearly recognizable taxa are known. Our analysis is based on 401 CO1-sequenced specimens collected from throughout mainland pri...
