High-Power Energy Storage and Stability of Ti3C2Tx MXene at Extreme Temperatures

This study demonstrates that Ti3C2Tx MXene electrodes exhibit exceptional high-power performance and thermal stability in 5 M H2SO4 across a wide temperature range (−40°C to 100°C), while identifying titanium dissolution as the primary degradation mechanism and validating that reducing electrochemical potential extends electrode lifespan through experimental testing and computational Pourbaix analysis.

Chitin-like Hollow Alumina Nano-adsorbent for Remediation of Arsenate- contaminated Water: Synthesis by Double Reversed-phase Microemulsion Method and Study of Enhanced Arsenate-removal Ability and Mechanism

This study reports the synthesis of chitin-like hollow alumina nanospheres via a double reversed-phase microemulsion method, which demonstrated exceptional arsenate removal efficiency (98.69%) and a high adsorption capacity (37.11 mg/g) through a mechanism governed by Langmuir isotherm and pseudo-second-order kinetics, highlighting their potential for effective water remediation.

Comparative Leaf Metabolomics Reveals Distinct Chemical Profiles and Putative New Metabolite Records in Ailanthus integrifolia subsp. integrifolia and Ailanthus triphysa

This study presents the first comparative leaf metabolomic and histochemical analysis of *Ailanthus integrifolia* subsp. *integrifolia* and *A. triphysa*, revealing substantial interspecific chemical divergence dominated by terpenoids, identifying putative first reports of specific quassinoids, and localizing key metabolites to epidermal and mesophyll tissues to establish a foundational resource for future chemotaxonomic and pharmacological research.
