Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

Advanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

High‐Tg Polythioesters From Isomerization Ring‐Opening Polymerization of a Renewable Oxanorbornane‐Fused Thionolactone

Angewandte Chemie, EarlyView.
A biobased tricyclic thionolactone undergoes selective isomerization ring‐opening polymerization to yield a high‐molecular‐weight polythioester with an exceptionally high Tg of 171°C, exceeding that of the analogous polyester. The polythioester efficiently depolymerizes through backbiting, while its hydrolysis and methanolysis reveal the critical ...

Effects of Different Kinds of Fruit Juice on Flavor Quality and Hypoglycemic Activity of Black Tea

Foods
At present, the heavy bitter taste, poor flavor quality and low functional activity of summer and autumn tea are the bottleneck problems restricting the low utilization rate of summer and autumn tea resources. The research and development of new products

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

The Study of Antioxidant and Anticarcinogenic Green Tea and Black Tea

Pakistan Journal of Biological Sciences, 2007
Tea is one of the most popular beverages consumed worldwide. The relationship between tea consumption and human cancer incidence is an important concern. The effect of tea extract and ingredients, polyphenol and caffeine on the mutagenicity of Sodium Azide was examined in vitro by using Salmonella typhimurium TA100, TA98 and TA1535 in the presence of ...

Spatiotemporally Controlled Sequential Chemo‐Immunotherapy Activates Pyroptosis for Robust Anti‐Tumor Immunotherapy

Advanced Science, EarlyView.
A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

Molecular Atlas of Key Food Odorants Reveals Mixture‐Level Organization and Enables Generative Aroma Design

Advanced Science, EarlyView.
KFO‐Atlas reveals how real‐world aromas are organized as structured mixtures rather than individual molecules. Building on these principles, KFO‐Gen, a generative AI framework, designs perceptually valid aroma formulations and reconstructs meat‐like aromas exclusively from plant‐derived odorants, providing a foundation for mixture‐level studies and AI ...
