The formidable challenge of membrane fouling by high-viscosity oils remains a primary impediment to the sustainable application of separation membranes in treating oil-contaminated wastewater. Consequently, there is an imperative for the development of oil-contaminated wastewater treatment membranes endowed with self-cleansing capabilities. The current review aims to delineate the landscape of self-cleansing membranes tailored for the treatment of oil-contaminated wastewater. Embarking from the foundational theories and benchmarks of self-cleansing, the self-cleansing functionalities were classified into active and passive modalities. We encapsulate the strides made in research, encompassing domains such as super-wettable surfaces, synchronously filtered self-cleansing, and post-filtration high-efficiency self-cleansing, while concurrently identifying extant constraints and prospective trajectories. By meticulously categorizing and dissecting self-cleansing functionalities, the aim of this work is delving into the fundamental tenets of self-cleansing within membranes intended for treating oil-contaminated wastewater, and furnishing guidance for the design and advancement of self-cleansing functionalities in oil-water separation membranes.

The combined metabolism and transcriptome of tail muscles reveal the effects of antimony pulse exposure on swimming behavior of Pelophylax nigromaculatus tadpoles

Science of the Total Environment 2025年 958卷 177929页

Due to the periodic emission of pollutants, the exposure mode of contaminants in water bodies is mostly pulse exposure, and the toxic effects of fluctuating exposure on aquatic animals are not consistent with traditional toxicological experiments of constant exposure. The toxic effects of heavy metal antimony (Sb) on the swimming behavior of Pelophylax nigromaculatus tadpoles after pulse exposure (PESb) and continuous exposure (CESb) for 28 days were explored. The mechanisms were analyzed from the perspectives of tail muscle metabolism and transcriptomics. Compared to the control group, PESb and CESb decreased the average speed of P. nigromaculatus tadpoles by 25.72 % and 18.08 %, respectively. PESb and CESb led to changes in 70 and 24 metabolites of tail muscle, respectively. PESb led to alterations in metabolic pathways related to pyrimidine metabolism, arginine biosynthesis, and glycerophospholipid metabolism. In contrast, CESb altered metabolic pathways such as alanine, aspartate, and glutamate metabolism. Compared to the control, 1225 and 1139 DEGs were identified for PESb and CESb, respectively. These DEGs were mainly associated with functions such as immune response, DNA replication, protein digestion, and absorption. It can be seen that PESb and CESb can alter the metabolism and transcriptome of the tail muscle of P. nigromaculatus tadpoles, leading to differential expression of individual movements. © 2024 Elsevier B.V.

Localized heating coupling with radical oxidation eliminating antibiotic resistance genes (ARGs) in interfacial photothermal Fenton-like disinfection process

Conventional oxidative disinfection processes are inefficient in eliminating intracellular antibiotic resistance genes (iARGs) due to the barrier of the cell membrane and the competitive reaction of cellular constituents within antibiotic-resistant bacteria (ARB), resulting in the widespread prevalence of ARGs in recycled water. This study presented the first application of localized heating coupling with advanced oxidation to destroy the resistant Escherichia coli cells and improved subsequent iARGs (blaTEM-1) degradation in a novel photothermal Fenton-like disinfection process. The Fe-Mn@CNT microfiltration membrane, comprising carbon nanotubes wrapped with Fe and Mn nanoparticles (Fe-Mn@CNT), was employed as a nanomaterial for photothermal conversion and H2O2 activation. The highly efficient absorption of full-spectrum photons by CNTs enabled the Fe-Mn@CNT membrane to concentrate light to generate localized intense heat, resulting in the destruction of ARB nearby, and the subsequent release of iARGs. Interfacial heat favored Fe-Mn-induced H2O2 activation, leading to the production of more ·OH, which in turn promoted the oxidation for ARG degradation and ARB cell damage. The results of the acetylcysteine quenching experiments indicated that interfacial heating and radical oxidation-induced accumulation of intracellular reactive oxygen species contributed to the elimination of about 1-log iARGs through direct attack. The integrity of the cell membrane, the morphology of ARB and the variation of i/e ARG copy numbers were observed to reveal that the introduction of interfacial heating aggravated the cell lysis and accelerated the iARGs release, resulting in the inactivation of 7.27-log ARB and the elimination of 4.64-log iARGs and 2.23-log eARGs. Localized heating coupling with ·OH oxidation achieved a 143 % increase in iARGs removal compared to the conventional Fenton-like oxidation. The interfacial photothermal Fenton-like disinfection process exhibited remarkable
