Atomic Layer Deposition‐Modified Bifunctional Electrocatalysts for Rechargeable Zinc‐Air Batteries: Boosting Activity and Cycle Life

Advanced Energy Materials, EarlyView.
The transition metal oxide is precisely deposited on the catalyst surface via atomic layer deposition (ALD), forming a protective layer with catalytic activity. Electrochemical experiments, theoretical calculations, and in situ X‐ray absorption spectroscopy (XAS) battery testing collectively demonstrate that the modified transition metal oxide ...

Household Financial Stress and Relationships During the COVID‐19 Pandemic: Findings From Australian Survey Data

Australian Journal of Social Issues, EarlyView.
ABSTRACT During the COVID‐19 pandemic, disruptions to finances and relationships were significant. Analysing Australian longitudinal survey data from May 2020 and August 2021, this study examines the Family Stress Model, which posits that financial stress influences relational dynamics within households.

Magnetic‐Field Induced Charge Accumulation in Scalable Magnetoelectric PVDF‐TrFE/Ni Composite Devices

Advanced Physics Research, EarlyView.
This study reports strong magnetoelectric effects in PVDF‐TrFE/Ni bilayer composites. Direct measurements of charge accumulation reveal high induced polarization, corresponding to open circuit voltages of 75 mV. Finite element simulations are in good agreement with experiments and demonstrate device scalability.

GaAs Growth on Ge‐Buffered Discontinuous (111)‐Faceted V‐Groove Silicon Substrates

Advanced Physics Research, EarlyView.
This work demonstrates antiphase boundary (APB)‐free GaAs growth on Ge buffers formed on discontinuous (111) V‐groove Si substrates. By tailoring the Ge buffer morphology to form well‐defined facets, APB formation is suppressed. This approach offers alternative solutions to achieving APB‐free III–V integration on CMOS‐compatible on‐axis silicon without

Corporate Climate Risk and Membership of Emission Trading Schemes

Business Strategy and the Environment, EarlyView.
ABSTRACT Using a sample of 5364 firms from 65 countries, we demonstrate that membership in the scheme increases firm climate risk. Further analysis reveals that the positive impact of membership on climate risk is pronounced among firms in carbon‐intensive industries. Our findings demonstrate that continental differences and legal origin could moderate
