Enhancing Anode‐Free Lithium Metal Batteries: A Lightweight MPTS‐MXene Current Collector for Superior Performance and Energy Density

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces an MPTS‐modified MXene current collector for anode‐free lithium metal batteries (AFLMBs). A key advantage of MPTS‐MXene is its ultralight weight, only 15% as heavy as standard copper per unit volume. Its special layered structure and Si‐O rich surface help lithium deposit smoothly and flat, while forming a protective layer that ...

On the Verge of Exclusion: The Unique Psychological Profile of the Threat of Social Exclusion

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Past research, often using Cyberball—an online ball‐tossing game with two or more preprogrammed players—showed that being socially excluded produces various negative emotions and lower need satisfaction. However, in everyday life, people may experience the threat of social exclusion more frequently than actual exclusion. Across two experiments
