Investigating the Customer Journey in Second‐Hand Fashion Platforms: Implications for Luxury Brand Management

Journal of Consumer Behaviour, Volume 24, Issue 2, Page 655-672, March 2025.
ABSTRACT Consumers' increasing environmental concerns are prompting a shift in fashion consumption, fueling the remarkable growth of the second‐hand market. Over the last decade, this trend has spurred the emergence of a plethora of online platforms dedicated to the resale of pre‐loved fashion items.

Recent Strategies Toward Durable and Ion‐Tolerant Transition Metal‐Based Electrocatalysts in Seawater Electrolysis

Carbon Energy, EarlyView.
Recent strategies address these challenges through ion‐specific regulation, encompassing chloride‐tolerant and chloride‐regulating anodes together with cathode designs that suppress OH− accumulation and Mg2+/Ca2+ coupling. This ion‐management‐oriented framework provides general guidelines for achieving stable, selective, and scalable seawater ...

Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

Oxygenophilic Cerium Promotes Active Species Generation and Modulates the Interfacial Water Network in Electrocatalytic Water Oxidation

Carbon Energy, EarlyView.
CeO2 dendrites are introduced to modify the NiSx/C3N4 nanorods, constructing hexagonal star‐like forest arrays (CeO2@NiSx/C3N4). The oxophilicity of Ce species generates abundant oxygen vacancies, which subsequently facilitate the in situ evolution of active amorphous NiOOH.

Judging by the Rules? The emergence of evaluation practices

Valuation Studies
How does evaluation work differently, and how do evaluation practices emerge, in different contexts? Drawing on a mixed-methods study of evaluation in figure skating and classical music, I discuss the divergent evaluative cultures in these settings ...

Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of
