Summary: Loading ultra-low concentrations of graphene oxide quantum dots (GQDs) into the polyamide (PA) layer of an outer-selective hollow fiber (OSHF) thin-film composite (TFC) membrane can enhance water permeability but may also impact membrane selectivity. Molecular dynamics simulation revealed that GQDs decrease reaction rates during interfacial polymerization (IP), reducing water permeability and acting as barriers to water molecules near the PA layer surface. At high loading, GQDs can aggregate and reduce membrane selectivity by forming non-selective voids at the interface between the PA layer and GQDs.

Summary: In this study, poly(ethylene glycol) diamine (PEG-diamine) was used as a key functional monomer to modify the conventional polyamide thin-film composite (PA-TFC) membrane via interfacial polymerization (IP). PEG-diamine changed the morphology and chemistry of the PA layer, resulting in a more hydrophilic and smoother surface for the modified membranes. The incorporation of PEG-diamine improved the separation performance of the membranes without sacrificing the reverse salt flux, and showed excellent antifouling properties against sodium alginate foulant.

Summary: Thin film composite (TFC) membranes are widely used in reverse osmosis (RO)-based desalination processes due to their ideal separation performance. In this study, porous polyketone membranes prepared via non-solvent induced phase separation (NIPS) were explored as substrates for fabricating high-performance TFC membranes. Investigations on structure control and chemistry regulation showed that different polyketone substrates led to significant differences in thin layer formation during interfacial polymerization (IP), resulting in TFC membranes with varied permeance and performance.

Summary: In this study, prechlorination experiments were conducted in sets of model raw water distribution systems with different doses. The results showed that the elevated dose of chlorine and prolonged hydraulic retention time (HRT) decreased the ratio of intact algal cells and enhanced water stability. The levels of dissolved organic carbon (DOC) and nitrogen (DON) initially increased but then decreased with the elevation of chlorine dose, while UV254 showed a monotonically increasing trend. This study also revealed the effects of prechlorination on extracellular polymeric substances aggregation behavior on pipe walls and microbial community composition.

Summary: Text classification is a fundamental problem in natural language processing. Graph-based models, such as GNN-based and GCN-based models, have recently been applied to this task and achieved excellent performance by modeling context from a global perspective. However, existing graph-based models often construct a corpus-level graph structure, leading to high memory consumption and overlooking local contextual information. To address these issues, this paper proposes a novel GNN-based model called TSW-GNN, which constructs a unique text-level graph for each text using two sliding windows. Extensive experiments on benchmark datasets demonstrate the improvement of TSW-GNN in classification accuracy compared to state-of-the-art models.

Summary: Drainage conditions and consolidation states can affect the deformation behavior of clayey soil under cyclic loading. The lateral deformation in soils under partially drained conditions is similar to those under undrained conditions with the increase of over consolidation ratio. Under undrained conditions, a large axial strain could accumulate with a small amount accumulation in excess pore water pressure, while under partially drained conditions, the resilient modulus of the soil decreases as the volumetric strain increases.

Summary: Understanding the ion transport in concentrated electrolytes is important. This study demonstrates an enhanced ion transport of water-in-salt (WIS) electrolytes in 2D nanochannel membranes. The mechanism involves a stratification process induced by functional groups, where a free anion layer moves between two continuous water-cation layers. Lithium-ion batteries with this confined electrolyte showed improved capacity and coulombic efficiency. This work provides new insights into the ion transport mechanism in nanoconfined concentrated electrolytes and offers strategies for designing high-performance and safe electrolytes for energy and environmental devices.

Summary: Photocatalytic self-Fenton technology is a promising strategy for pollutant removal in wastewater, but the production rate of in situ H2O2 affects its performance. This study proposes a single-layer BiOCl nanoflower induced by biosurfactant to increase oxygen adsorption and reduction rate. The results show that hydrophobic groups on the micelle surface increase O-2 adsorption sites and expand adsorption capacity, leading to enhanced H2O2 production and increased sulfamethoxazole degradation efficiency.

Summary: This study aimed to investigate the clinical features, prognosis, and treatment of advanced-stage non-nasal type extranodal natural killer/T-cell lymphoma (ENKTCL). The results showed that non-nasal type ENKTCLs had higher Ki-67 expression levels compared to nasal type disease. The non-nasal group showed slightly inferior survival outcomes compared to the nasal group, but without statistically significant differences. Eastern Cooperative Oncology Group (ECOG) score >= 2 and lactic dehydrogenase (LDH) elevation were significantly correlated with worse overall survival in the non-nasal group.

Summary: In this study, we investigate the transport of three typical anions under confinement and reveal that dehydration and related ion-pore interactions play a crucial role in anion-selective transport. We show that strongly hydrated ions have hindered transport due to their enhanced ion effective charge, while weakly hydrated ions have greater permeability. Our findings suggest that precisely regulating ion dehydration can enable the development of ideal ion-selective membranes.

Summary: The intelligent regulation of ion flow in biological ion channels is essential to life. Artificial ion channels have been developed to intelligently control ion permeation. However, their gating performance is inferior to that of biological ion channels. Recently, emerging advanced materials have provided promising tools to fabricate responsive sub-nanofluidic channels with efficient gating performance.
