Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

open access: yesAdvanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

Born to Fear the Machine? Genetic and Environmental Influences on Negative Attitudes toward AI Agents

open access: yesAdvanced Science, EarlyView.
Why do some people fear or distrust AI agents more than others? This twin study shows that negative attitudes toward AI may partly stem from genetic factors, linking them to traits like victim sensitivity and moral beliefs. These findings show that it is not only nurture but also nature that shapes our views of AI, with implications for future human–AI

Toward Understanding the Stability of Single‐Atom Catalysts in Oxygen Evolution Reactions

open access: yesAdvanced Energy Materials, EarlyView.
Enhancing the stability of single‐atom catalysts for the oxygen evolution reaction hinges on understanding support interactions, local geometry, and structural dynamics. Transitioning to OH‐modified surfaces offers a promising route to cap surface metals and prevent leaching, paving the way for the next generation of stable OER SACs.

Effects of the Operating Point of Photovoltaic Strings on Sizing of DC‐ and AC‐Connected Energy Storage Systems for Power Smoothing

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study is based on measured current–voltage curves of a 23 module photovoltaic (PV) string. The results of the study show that, in practice, following the maximum power point (MPP) closest to the nominal MPP voltage instead of the global MPP has no major effect on sizing of energy storage systems for power smoothing of PV strings. Photovoltaic (PV)
