Bioinspired Microreactor for Iodide Adsorption and Photooxidation Recovery

Advanced Science, EarlyView.
A bioinspired micro‐ionic‐reactor based on porous organic polymer (MIR‐POP) integrates rapid iodide capture with in situ photooxidative conversion, achieving record uptake capacity and high uptake efficiencies in simulated mining wastewater and natural brine. This bioinspired microreactor strategy offers a new avenue for sustainable iodine recovery and

Paramagnetic radiation-induced defect centres and their correlation with the optical properties of irradiated advanced ceramic breeder pebbles

Nuclear Materials and Energy
Advanced ceramic breeder (ACB) pebbles, primarily composed of lithium orthosilicate (Li4SiO4) with lithium metatitanate (Li2TiO3) as a second phase, are currently under development and testing as the European Union’s reference material for tritium ...

Targeted H2S Delivery System Attenuates Blood‐Spinal Cord Barrier Disruption after Spinal Cord Injury by Reshaping the Ferritinophagy Pathway

Advanced Science, EarlyView.
The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...

Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

Advanced Science, EarlyView.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...

Characterization of Paramagnetic Species in Seeds by Electron Paramagnetic Resonance (EPR)

RE&PQJ
Paramagnetic species were characterized in the seeds of radish wild, rice, mustard, wheat, oats, sorghum, sunflower, soybean, cotton, beans, maize and barley by Electron Paramagnetic Resonance (EPR). Some iron complexes such as goethite, hematite, magnetite, and ferrihydrite, normally present in the soil, were also investigated by EPR, since their ...

Lewis Pair‐Engineered CuMnOx as Cold‐Adapted Multinanozyme for Cooperative Hydrolytic and Oxidative Degradation of Raw Corn Stalk

Advanced Science, EarlyView.
A Lewis pair site design strategy was established to construct Cu‐doped Mn‐based amorphous nanozymes, where Mn and oxygen vacancies generate cooperative acid‐base pairs. The resulting multinanozyme integrates glycosidase‐, oxidase‐, and cold‐adapted enzyme‐mimicking activities, enabling cooperative depolymerization of cellulose and hemicellulose ...
