Spatially Separated Redox Centers in One‐Dimensional Sp2‐Carbon Covalent Organic Frameworks Enable Synergistic Photocatalytic Palladium Recovery and Bisphenol A Mineralization

Advanced Science, EarlyView.
A one‐dimensional sp2‐carbon covalent organic framework with spatially segregated redox centers integrates a dual photosensitizing system and a cationic interface for synergistic photocatalysis. The material achieves exceptional palladium recovery (1749 mg g−1) and bisphenol A mineralization (0.1710 min−1) without sacrificial agents, demonstrating ...

Design, synthesis and biological evaluation of novel aliphatic amido/sulfonamido-quaternary ammonium salts as antitumor agents

, 2013
RhoB, one of the upstream signaling proteins of the phosphatidylinositol-3- kinase (PI3K)/Akt pathway, is frequently mutated in human cancer. Based on a piperazine alkyl derivative that induced apoptosis via up-regulation of RhoB, we synthesized novel ...

A Cationic Supramolecule With Potent Antifungal Activity, Single‐Species Selectivity, and Strong Synergy With Echinocandins

Advanced Science, EarlyView.
We introduce a new membrane‐active antifungal design, Gua‐SMACS‐16, that exhibits high potency and single‐species selectivity for C. tropicalis while sparing other close species in the Candida genus. Moreover, when combining with caspofungin, a clinical antifungal drug inhibiting 1,3‐β‐glucan synthase, they exhibit ultra‐strong synergy across a panel ...

A New Customizable Surfactant LLPS Strategy for Sustainable and Highly Efficient Radioactive Metal Ion Separation

Advanced Science, EarlyView.
A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

Advanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

Synthesis, characterization, and performance of a novel static dissipative additive for refined oils via quaternary ammonium segment modification

Fuel Processing Technology
Refined oils, such as gasoline, diesel, and aviation kerosene, are primarily composed of hydrocarbon compounds. As poor electrical conductors, these oils accumulate static charges through friction during storage, transportation, and handling. When charge

Synergistic Probe Combining Lysosome Anchoring and Tumor Defense System Targeting for Precise Tumor Visualization

Advanced Science, EarlyView.
A new generation of high‐precision fluorescent probes based on the lysosomal characteristics in tumor metabolic reprogramming and overexpressed tumor markers. The probe (CN‐D‐GGT) selectively label cancer cells in co‐culture systems and distinguish tumor lesions from inflamedand normal tissues in vivo, enabling precise tumor imaging.

Evaluation of powdered disinfectants to reduce bacterial contamination of footwear

Journal of Applied Poultry Research
Summary: Footwear is a known route for spreading microorganisms to farms and between poultry houses. While disinfectant foot pans are commonly used, liquid products lose efficacy when organic matter such as feces or litter is present.
