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

Methodological advances in the analysis, assessment and intervention of industrial landscapes [PDF]

, 2018
We are currently witnessing a gradual extension of the concept of heritage. This idea has evolved to encompass landscapes and is even reaching into an area which, until recently, had not received sufficient attention: industrial heritage. This new notion

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

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.

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

Flavour and Fragrance Journal, EarlyView.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

The Depth‐Specific Effects of Acupuncture for Post‐Stroke Gastroparesis: Protocol for a Randomized Controlled Trial of Deep Versus Superficial Needling

Gut Medicine, EarlyView.
ABSTRACT Background Post‐stroke gastroparesis (GP) is a debilitating complication that severely impairs quality of life. Although abdominal acupuncture is widely used, robust evidence regarding its efficacy, particularly concerning the critical parameter of the needling depth, is still lacking.

Employee Delight: Conceptualization, Antecedents, and Consequences

Human Resource Development Quarterly, EarlyView.
ABSTRACT This article examines the concept of employee delight as a distinct construct within organizational behavior. Based on a systematic literature review, we analyze 10 empirical studies that explicitly address this phenomenon. We propose a multidimensional conceptualization of employee delight as an affective state of highly positive valence and ...
