Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

Dynamic Polydisulfide Latex via Emulsion Ring‐Opening Polymerization of Cyclodisulfides

open access: yesJournal of Polymer Science, EarlyView.
A polydisulfide latex with a high molar mass was achieved by emulsion polymerization process starting from a dithiol. The mechanism reveals an entropy‐driven ring‐opening polymerization involving disulfide macrocycle intermediates. The polydisulfide particles can be degraded by thiol‐disulfide exchange, and the disulfide fragments can be reengaged in a

Simulated elephant foraging alters tree root exudation rates: Species‐specific responses and implications for belowground carbon dynamics in tropical forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.

Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation

open access: yesSmall, EarlyView.
An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.

Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

open access: yesSmall, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

MOF‐Derived Bi2WO6/MXene Ternary Heterojunction as a Highly Efficient Piezocatalyst for Ultrasound‐Driven Hydrogen Evolution and Oxygen Evolution Reaction

open access: yesSmall, EarlyView.
A Bi‐MOF‐derived Bi‐rich Bi2WO6/Bi3.84W0.16O6.24 ternary heterojunction with Ti2C MXene is developed as a highly efficient piezocatalyst. Ultrasound‐driven charge separation via a dual‐phase oxide and conductive MXene electron highway achieves an H2 evolution rate of 1450.1 µmol g−1h−1 through an unconventional •OH‐mediated pathway, with concurrent ...
