The hollow polyaniline (PANI) micro/nanospheres are obtained through a simple monomer polymerization in alkaline solution with Triton X-100 Micelles as soft templates. The hollow PANI micro/nanospheres demonstrate rapid and effective removal ability for Chromium (VI) (Cr (VI)) in a wide pH range, and the maximum removal capacity can reach 127.88 mg/g at pH 3. After treated with acid, the used hollow PANI micro/nanospheres have about the similar removal capacity of Cr (VI) from wastewater.

Bacterial outer membrane vesicles (OMVs) have emerged as promising vehicles for anticancer drug delivery due to their inherent tumor tropism, immune-stimulatory properties, and potential for functionalization with therapeutic proteins. Despite their advantages, the high lipopolysaccharide (LPS) endotoxin content in the OMVs raises significant safety and regulatory challenges. In this work, we produce LPS-attenuated and LPS-free OMVs and systematically assess the effects of LPS modification on OMVs' physicochemical characteristics, membrane protein content, immune-stimulatory capacity, tolerability, and anticancer efficacy.

Parasitic structure defect blights sustainability of cobalt-free single crystalline cathodes.

Recent efforts to reduce battery costs and enhance sustainability have focused on eliminating Cobalt (Co) from cathode materials. While Co-free designs have shown notable success in polycrystalline cathodes, their impact on single crystalline (SC) cathodes remains less understood due to the significantly extended lithium diffusion pathways and the higher-temperature synthesis involved. Here, we reveal that removing Co from SC cathodes is structurally and electrochemically unfavorable, exhibiting unusual voltage fade behavior.

Bismuth-based photocatalysts proved to have remarkable photoactivity for antibiotic degradation from water. However, the two significant challenges of bismuth-based photocatalysts are the fast charge recombination rate and higher energy band gap. This study successfully synthesized a novel I-Bi/BiWO/MWCNTs (C-WBI) heterostructure composite photocatalysts with shorter energy band-gap and higher charge production capability through interfacial amidation linkage.

The study of emerging contaminants (ECs) in water resources has garnered significant attention due to their potential risks to human health and the environment. This review examines the contribution from computational approaches, focusing on the application of machine learning (ML) and molecular dynamics (MD) simulations to understand and optimize experimental applications of ECs adsorption on carbon-based nanomaterials. Condensed matter physics plays a crucial role in this research by investigating the fundamental properties of materials at the atomic and molecular levels, enabling the design and engineering of materials optimized for contaminant removal.

Nitrogen-removal promotion is a significant problem when biological nitrogen removal is used to treat ammonium nitrogen (NH-N) wastewater with a low chemical oxygen demand (COD)/NH-N (C/N) ratio. In this work, the biological nitrogen removal capacity of the biological contact oxidation reactor (BCOR) system was enhanced through the enrichment of Acidobacteria. The system was successfully started from Day 1 to Day 50 and stably operated through temperature, pH, and dissolved oxygen (DO) regulation from Day 51 to Day 254.
