Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

Angewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.

Entrapped elemental selenium nanoparticles affect physicochemical properties of selenium fed activated sludge

, 2015
Selenite containing wastewaters can be treated in activated sludge systems, where the total selenium is removed from the wastewater by the formation of elemental selenium nanoparticles, which are trapped in the biomass. No studies have been carried out

Mesenchymal Stromal Cell‐Based Cell–Drug Conjugates for the Treatment of Acute Liver Failure

Advanced Science, EarlyView.
Mesenchymal stromal cell (MSC)‐based cell‐drug conjugates are constructed by anchoring rosiglitazone‐loaded nanoparticles onto the MSC surface. Sustained rosiglitazone release enhances MSC proliferation and paracrine activity while promoting anti‐inflammatory macrophage polarization.
