The impacts of technology-led event sustainability consumption values on personal social responsibility and collective psychological outcomes
Full text linkThis study investigates how technology-led event sustainability consumption values (TESCVs) influence attendees’ attitudes toward sustainable music events, personal social responsibility, and collective psychological outcomes. Surveying 450 participants at technologically advanced music events in South Korea, it identifies technology-led accessibility, emotional, epistemic, and social values significantly influencing attitudes toward sustainable events. These positive attitudes correlate with increased social well-being, global identity, and civic engagement through personal social responsibility. Environmental activism partially moderated effects, but collectivism orientation did not significantly affect the outcomes. Findings highlight TESCVs’ role in promoting a sustainable event culture, offering insights for researchers, event organizers, and destination marketers

Operando characterization of the reversible “Zinc oxide – Zincate – Metallic Zinc” transformations in rechargeable Ni-Zn alkaline batteries
Full text linkRechargeable Ni-Zn alkaline batteries are of growing interest due to their intrinsic safety, high energy density, and environmental friendliness. To optimize the performance of the ZnO electrode in these batteries, it is essential to understand complex transformations that occur during charge and discharge of the reaction: . In this study, we employ a series of operando characterization techniques, including X-ray diffraction (XRD), Raman spectroscopy, and online electrochemical mass spectroscopy (OEMS), to investigate the surface dynamics on the ZnO electrode. Our findings reveal the significant impacts of decoupling the chemical and electrochemical processes, resulting in hydrogen gas evolution, diffusion of anions in alkaline electrolyte, and other side reactions. Importantly, by adjusting the current densities during charge and discharge, these effects can be modulated. This study provides valuable insights into the complex surface reactions, which can ultimately contribute to the advancement and commercialization of Ni-Zn batteries
A novel catalyst featuring highly stable cobalt and manganese nitride nanoclusters dispersed on single atom-anchored carbon nanotubes for hydrolytic release of hydrogen from ammonia borane
Full text linkThis study investigated the long-term stability of cobalt (Co) and manganese nitride (Mn4N) nanoclusters in the catalytic hydrolysis of a promising hydrogen (H2) storage material, ammonia borane (H3NBH3; AB), to release H2. It was previously found that Co nanoparticle/Co single-atom catalysts (Co NP/Co SACs) anchored on carbon nanotubes (CNT) exhibited excellent reactivity and stability towards AB hydrolysis and high performance in the H2 evolution reaction in alkaline media. Therefore, the current study synthesised CoMn4N/Co-Mn-Nx-CNT- 200–800, a CoMn-based catalyst with Co and Mn4N nanocluster active sites, and examined its performance in AB hydrolysis. CoMn4N/Co-Mn-Nx-CNT-200–800 generated three equivalents of H2 from AB within 5 min, outperforming the catalytic activity of previously reported Co NPs/Co SACs. Moreover, CoMn4N/Co-Mn-Nx-CNT- 200–800 maintained over 90 % of its initial activity after 50 cycles of AB hydrolysis. This exceptional long-term stability is attributable to CoMn4N/Co-Mn-Nx-CNT-200–800 bearing Co/Mn4N nanoclusters that were strongly adhered onto graphitic layers, thereby preventing metal-atom aggregation and leakage during AB hydrolysis. Thus, CoMn4N/Co-Mn-Nx-CNT-200–800 displayed a maximum effective H2 generation rate of 8372 mLH2⋅gCoMn 1 ⋅min 1. These results highlight the potential of dispersed bimetallic nanocluster catalysts, such as CoMn4N-based catalysts, for practical and sustainable H2 generation via AB hydrolysis. In addition, the insights gained from this study can inform the design of highly active and stable non-precious metal-based catalysts for energy-related applications
