Flocculants are essential for removing pollutants from wastewater, yet conventional organic and inorganic types often lack renewability and pose risks of secondary pollution. In this study, a cationic cellulose nanofiber (CCNF) flocculant was developed from rice straw, offering enhanced flocculation performance, sustainability, and environmental compatibility. The cellulose nanofiber was extracted and cationically modified under mild conditions.

By contrast, oncolytic viruses can always activate intratumoral DCs to initiate virus-specific immunity to eliminate viruses which will in turn reduce the anti-tumor effect of these viruses. To bridge the two approaches, we developed virus-mimicking nanoparticle (V-mimic) through self-assembly of artificial cyclic gadolinium-based GAMP (c·Gd·GAMP, a STING agonist), double-stranded RNA analog (Poly I:C), and indocyanine green (ICG).

However, the immune response of the in-situ tumor vaccines is often undermined by the residual tumor cells and their induced immunosuppressive tumor microenvironment (TME), which is attributed to insufficient photothermal effects stemming from the limited accumulation of photosensitizers. To overcome these limitations, we developed multi-functional nanoparticles (VI@Gd-NPs) that integrate a tumor vasculature-specific disrupting agent (Vadimezan, Phase III clinical drug), a photosensitizer (Indocyanine Green, ICG), and a magnetic resonance imaging contrast agent (Gadolinium, Gd) through chemical self-assembly.

This study aimed to explore the downstream mechanism of METTL3-mediated mA modification in IS. GSE16561 and GSE22255 were downloaded from the Gene Expression Omnibus database for analysis of differentially expressed genes (DEGs), and it was found that METTL3 mRNA was downregulated in IS.

Photocatalytic degradation is a promising method for removing antibiotics from water, but its practical implementation requires improvements in photocatalyst activity and recovery. Here, a novel graphite felt-supported MnS/Polypyrrole composite (MnS/PPy/GF) was constructed to achieve effective adsorption of antibiotics, stable loading of photocatalyst, and rapid separation of spatial charge.

However, in practice, the supplementary addition of limestone is necessary to balance the alkalinity consumption during SAD operation, which increases water hardness and reduces the effective reaction volume. In this study, a coupled sulfur and electrode-driven autotrophic denitrification (SEAD) process was proposed with superior nitrate removal performance, less accumulation of sulfate, and self-balance of acidity-alkalinity capacity by regulating the applied voltage.

Here we show that, by applying a bias potential on the photocatalyst, the photoelectrochemical (PEC) method can address these limitations. We demonstrate that, owing to efficient spatial charge-carriers separation driven by the applied bias, the PEC method enables efficient and durable U extraction.

However, BS such as sodium deoxycholate (NaDC) can't stabilize an oil-in-water (O/W) emulsion alone due to its unusual molecular structure. In this paper we report that these emulsifiers with poor emulsifying ability can be transformed to highly efficient emulsifiers by combining with negatively charged particles (silica or montmorillonite).
