One‐Step, High‐Yield Deconstruction of Kraft Lignin Into a Redox‐Active Small Molecule Using Sonicated Emulsive Water Microdroplets

Small, EarlyView.
This study reports a rapid (∼20 min), uncatalyzed deconstruction of Kraft lignin (∼14.2 kDa) using sonicated emulsive water microdroplets (SEWMs) in the presence of 2.5 M HNO3. The work demonstrates the combined synergistic effect of sonochemical excitation and microdroplet redox chemistry to induce C─C bond cleavage and reductive nitration to ...

Monodisperse Condensed Tannin and Derived Carbon Nanospheres Featuring Well‐Defined Surface‐Structured Metal Species

Small, EarlyView.
Uniform, size‐tunable polyphenol nanospheres are assembled from condensed tannins in water at ambient conditions via controlled supramolecular interactions between tannin and diamines. Their phenolic–amine surfaces template highly dispersed metal species that resist sintering during pyrolysis.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...
