Development and Psychometric Validation of the Chinese Online Disinhibition Scale for Adolescents
PsyCh Journal, Volume 15, Issue 4, August 2026.ABSTRACT Online disinhibition significantly influences adolescents' communication and behaviors in digital environments, yet culturally adapted measurement tools remain limited in China. This study aimed to develop and validate a Chinese version of the Online Disinhibition Scale (ODS‐C) based on Suler's (2004) theoretical framework.

四川大学学报. 自然科学版, 1984 把5/121表成三个单位分数的和,即求方程 5/121=1/x+1/y+1/z的正整数解问题,Blericher得到一组解为(x,y,z)=(25,759,208725)。但是,Bleri-cher不知道三项展开式能否具有一个小于208725的最大分母,这个问题容易解决。看来更有意义的问题是:(1)是否有max(x,y,z)>208725的解。本文得到(1)的全部解共21组,其中max(x,y,z)>208725的解一组。从而解决了以上问题。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

Glycerophosphocholine‐Mediated Dual Regulation for Highly Stable Aqueous Iron‐Ion Batteries
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Iron‐ion batteries (FeIB) offer the advantages of low cost and high capacity, demonstrating potential for large‐scale energy storage. However, severe hydrogen evolution reaction (HER) occurs during cycling, which significantly impacts battery lifespan.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Li–O2 batteries garner widespread attention owing to their remarkable theoretical specific capacity. Nevertheless, the feasible implementation of the system is hindered by sluggish cathode reaction kinetics and poor anode stability. Herein, the carbon dots (CDs) with ‐OH, ‐NH2, and ‐COOH groups are synthesized and employed as electrolyte ...
