Sulfonated, Disulfide‐Bridged Polymer Networks for Atmospheric Water Harvesting
Small, EarlyView.Atmospheric water harvesting is a promising solution to the water crisis. Here, disulfide‐containing hyper‐crosslinked‐style polymers are prepared by combined Friedel–Crafts alkylation and thiol self‐condensation. Exhibiting exceptional uptake capacities, the polymers demonstrate dynamic bonding behavior.

Analyzing the Catalytic Role of Active Site Residues in the Fe-type Nitrile Hydratase from \u3cem\u3eComamonas testosteroni\u3c/em\u3e Ni1 [PDF]
, 2015 A strictly conserved active site arginine residue (αR157) and two histidine residues (αH80 and αH81) located near the active site of the Fe-type nitrile hydratase from Comamonas testosteroni Ni1 (CtNHase), were mutated. These mutant enzymes were examined

Research advances in the applications of mitochondria‐targeted cyanine dyes in imaging
VIEW, EarlyView.Near‐infrared (NIR) fluorescence imaging, a novel non‐invasive diagnostic tool, plays a crucial role in the imaging and monitoring of solid tumors. At its core are NIR fluorescent dyes, which are widely utilized due to their ability to minimize tissue autofluorescence interference, thereby significantly enhancing the signal‐to‐noise ratio (SNR) and ...

Redox Proteomics and Platelet Activation: Understanding the Redox Proteome to Improve Platelet Quality for Transfusion. [PDF]
, 2017 Blood banks use pathogen inactivation (PI) technologies to increase the safety of platelet concentrates (PCs). The characteristics of PI-treated PCs slightly differ from those of untreated PCs, but the underlying reasons are not well understood.

Linking Superoxide Production and Scavenging in Plant Development
Plant, Cell &Environment, Volume 49, Issue 4, Page 2048-2068, April 2026.ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...
