Micro and nanostructured phases obtained by mechanical alloying - low temperature annealing in AB5-H2 systems [PDF]

, 2015
In this work, the characteristics of a commercial sample of LaNi5 are compared to those of an experimental one obtained by mechanical alloying followed by low temperature annealing.

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

Carbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

Phosphorylation regulates the bound structure of an intrinsically disordered protein: The p53-TAZ2 case [PDF]

, 2016
Disordered regions and Intrinsically Disordered Proteins (IDPs) are involved in critical cellular processes and may acquire a stable three-dimensional structure only upon binding to their partners.

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

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

European Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.
