Polymer particles, including synthetic polymers such as poly(methyl methacrylate) (PMMA) and poly(styrene-co-divinylbenzene) (P(S-co-DVB)) beads, have been widely used as enzymatic supports and drug carriers. In this sense, it is important to understand the stabilization or degradation of such polymer matrices under specific chemical and enzymatic media. For this reason, the present work aims to evaluate the current status and prospects of treatments of PMMA and P(S-co-DVB) particles intended for biotechnological and biomedical applications under basic, acidic, and enzymatic environments.

Dissolved organic matter (DOM) plays a key role in grassland carbon biogeochemistry and shows sensitivity to global climate change, particularly nitrogen (N) deposition. We investigated the soil DOM molecular composition by UV-Vis and fluorescence spectroscopy, and FT-ICR MS through a N addition experiment (CK, N5, N10, N20, and N40 [0, 5, 10, 20, and 40 g N m-2 year-1, respectively]) in a desert steppe of northwest China. Moderate N inputs (N5-N20) caused a dose-dependent increase in DOM content (9.

A precise modulation of heterogeneous catalysts in structural and surface properties promises the development of more sustainable advanced oxidation water purification technologies. However, the poor catalyst stability due to covering of surface-active sites by oxidation intermediates remains a key bottleneck to their practical applications. Herein we propose a simple defect-induced in-situ single-atom anchoring strategy to overcome this challenge by creating unique asymmetric active-sites on the catalyst surface.

Bacterial biofilms attach to various surfaces and represent an important clinical and public health problem, as they are highly recalcitrant and are often associated with chronic, nonhealing diseases and healthcare-associated infections. Antibacterial agents are often not sufficient for their elimination and have to be combined with mechanical removal. Mechanical forces can be generated by actuating nonspherical (anisotropic) magnetically responsive nanoparticles in a rotating magnetic field.

The increasing discharge of mineral processing wastewater containing recalcitrant benzohydroxamic acid (BHA) poses significant environmental and health risks. This work developed a Pt@HNT/FeO (PHF) bubble-propelled catalyst by encapsulating Pt nanoparticles within halloysite nanotubes (HNT) lumens and anchoring FeO on the exterior surface to degrade BHA. The PHF/HO system achieved 90% BHA degradation efficiency within 90 min, significantly outperforming conventional HNT/FeO (HF)/HO system (38%).
