Summary: Recent advances in nanotechnology have led to the development of nanofiltration membranes using carbon dots to enhance performance. By incorporating carbon dots with cationic amine groups (PEI-CDs) or anionic sulfonate groups (PS-CDs) into the polyamide selective layer of thin-film nanocomposite (TFN) membranes, charged nanovoids are created to improve water permeation and ion rejection. The TFN-PS-CDs membrane shows outstanding performance with significantly increased water permeability and higher rejection rate compared to pristine membranes. This work provides insights into designing efficient filtration processes using nanovoids in polymeric membranes.

Summary: The production of photocatalytic self-assembled amphiphilic polymers enables selective control over reactions based on the substrate's physical properties. By polymerizing benzothiadiazole-based photocatalysts into hydrophilic or hydrophobic compartments, we achieved stark differences in reactivity for polar substrates but similar performance for hydrophobic substrates. Additionally, the use of secondary swelling solvents led to a significant increase in conversion for a radical carbon-carbon coupling reaction.

Summary: A lattice theory is proposed for block copolymer solutions near the boundary between the micellization and liquid-liquid phase separation regions. A new kinetic process of micellization is suggested, where small concentrated-phase droplets are first formed and then transformed into micelles in the early stage of micellization. Furthermore, a unique ripening process is observed in the late stage of phase separation, where the growing concentrated-phase droplet size is proportional to the square root of the time.

Summary: Ultrafiltration membranes derived from block copolymers with tunable pore structures and intrinsic surface functions are prepared by a simple spray-coating method. The addition of water as a pore-forming agent leads to phase separation during spray coating, resulting in the formation of nanoscale pores in the composite membranes. The membranes exhibit good ultrafiltration performance and intrinsic fouling resistance, making them comparable or better than those prepared by more complicated processes.

Summary: Microphase separation in a binary blend of oppositely charged polymers can be stabilized electrostatically, providing a route to control microstructure. The phase behavior is affected by differences in charge density and dielectric constant of the polymers, and specific ordered phases can be stabilized when the minority component has a higher dielectric constant. This system suggests a possible route to large-unit-cell complex-sphere phases.

Summary: This review article focuses on the molecular structure-phase structure-property relationship of block copolymer electrolytes (BCPEs). By controlling the phase-separated structures, the tradeoff between mechanical strength and ionic conductivity can be decoupled. The conductivity of BCPEs is determined by the molecular structure of block copolymers and the type and concentration of additives, and the manipulation of phase-separated structures helps strengthen their mechanical support and ion transport. The article summarizes the research status and optimization strategies for BCPEs, presents methods to control the phase behavior of BCPEs, and classifies BCPEs into dual-ion conductor and single-ion conductor, analyzing their advantages and disadvantages. A design rationale for high-performance quasi-solid-state BCPEs is proposed, and polymerization methods for the regulation of molecular and phase structure are elaborated.

Summary: Wave splitting, an important application in wavefront modulation, has significant significance in practical engineering and academia. However, the available techniques for wave splitting are scarce aside from conventional metasurfaces governed by the generalized Snell's law. In this study, based on the newly proposed high-order diffraction theory, we design a simply structured elastic metagrating for the splitting of flexural waves in plate-like structures. Theoretical models, numerical simulations, and experiments are conducted to validate the effectiveness of our designs. This study provides a general method for designing wave splitters.

Summary: A method was developed to precisely tailor the pore size of PSf-b-PEG membranes in sub-5 nm via the NIPS process. By mixing selective solvents of Ts and THF in various ratios, the casting solution properties and pore size of the membranes were finely tailored. The PSf-b-PEG membranes showed a nanofibrous structure with high porosity and mechanical strength, and even with a pore size of 2 nm, the pure water permeance was still high, indicating their potential for practical applications.

Summary: This study proposes a novel wastewater treatment scheme that combines chemically enhanced primary treatment (CEPT), partial nitritation and anammox (PN/A), and anaerobic digestion (AD) to achieve energy-neutral wastewater treatment. By adding FeCl3 to the CEPT process, high removal rates of COD and phosphate were achieved, and alkalinity was reduced. Stable accumulation of nitrite was achieved in an aerobic reactor using a novel acid-tolerant ammonium-oxidizing bacteria (AOB), Candidatus Nitrosoglobus. After polishing in an anoxic reactor (anammox), satisfactory effluent quality was obtained. The integrated system demonstrated stable performance and could achieve energy self-sufficiency.

Summary: Anthropogenic global warming affects mobile terrestrial insects by changing their activity levels and distribution patterns. Heat extremes induce physiological responses in insects, causing them to either decrease activity or seek out favorable microhabitats. The availability of these microhabitats is affected by anthropogenic land transformation, which reduces habitat heterogeneity. It is important to understand the combined effects of these global change drivers on insect activity.

Summary: The study found that B. ovatus is an effective catcher of VB12 and can alleviate VB12 deficiency in patients with type 2 diabetes. In addition, it was found that the levels of methylmalonic acid and homocysteine increased, which converted methylmalonic acid into HFD-induced metabolic disorders. The results of the study suggest that metformin increases the intracellular accumulation of VB12 in B. ovatus through upregulation of btuB, enhancing competition and aggravating VB12 deficiency in the host.

Summary: Metagenomic and metatranscriptomic analyses were performed to reveal the microbial ecology of two biofilm systems that achieve high-level nitrogen removal through the coupling of anammox and n-DAMO processes in low-strength domestic sewage and high-strength sidestream wastewater. Different nitrogen loadings resulted in different combinations of anammox bacteria and anaerobic methanotrophs, and heterotrophic populations actively performed partial denitrification or DNRA using organic intermediates from methane breakdown. Additionally, two novel genomes belonging to Ca. Methylomirabilis were recovered, with one showing the capability of nitrate-dependent anaerobic methane oxidation.
