Stereodivergent C‐(Hetero)Aryl Glycosylation by Nickel‐Catalyzed Redox‐Neutral Cross‐Coupling of Glycosyl Sulfonyl Hydrazides

Angewandte Chemie, EarlyView.
A nickel‐catalyzed C–C cross‐coupling protocol employing bench‐stable glycosyl sulfonyl hydrazides as practical glycosyl radical precursors is reported. A variety of (hetero)aryl iodides underwent cross‐coupling under redox‐neutral conditions to afford structurally diverse unprotected C‐(hetero)aryl glycosides.

Super-resolution DOA estimation based on sparse spectrum fitting

Dianzi Jishu Yingyong, 2019
The ambient noise at any two different sensors, in practice, may correlate with each other, and the spatial distribution of ambient noise intensity may be directional because of wind and shipping noise sources. A linear harmonic noise model is considered

Metagenomic Association Uncovers Host Genotype‐Structured Rhizobacterial Networks and Novel Taxa That Enhance Soybean Salt Tolerance

Advanced Science, EarlyView.
An STI‐guided metagenomic association framework links soybean salt‐tolerance phenotypes with rhizosphere microbiome composition and network organization in natural saline soils. The approach identifies candidate beneficial taxa, including Thalassospira xiamenensis, and provides an efficient strategy for mining stress‐protective microbes from native ...

Rare‐Earth–Sulfur Surface Modification Enables SiC Ceramics for Low‐Frequency Electromagnetic Wave Absorption in Extreme Environments

Advanced Science, EarlyView.
By altering surface chemical bonds to prolong relaxation time and shift absorption to lower frequencies, SiC/rare earth–sulfur (RE─S, RE = La, Ce, Pr, Sm, Gd, Er) materials achieve excellent low‐frequency electromagnetic wave absorption under extreme conditions, offering a new direction for designing high‐performance SiC‐based absorbers.
