Summary: Membrane fouling is a significant challenge in membrane separations, and hydrophilic membrane surface modification can enhance fouling resistance. This study presents a new hydrophilic membrane coating based on 1,4-benzoquinone and polyetheramines for modifying polysulfone ultrafiltration membranes. The results show that the modified membranes exhibit comparable fouling resistance to polydopamine-modified membranes, indicating the potential of these coatings in mitigating fouling.

Summary: In this study, a novel nanocomposite was developed by functionalizing the synthesized magnetic-graphene oxide with crystalline nanocellulose and zwitterionic polymers to address the challenges of bio-fouling in ultrafiltration membranes. The nanofiller improved the hydrophilicity and roughness of the membranes, resulting in higher water flux, flux recovery ratio, and anti-fouling properties. The hydration layer formed by the zwitterionic groups on the nanocomposite surface reduced the adhesion of biomolecules and microorganisms, providing advanced anti-fouling properties. The nanocomposite membranes also exhibited improved biofouling resistance against Gram-positive/negative bacteria through anti-adhesion or antimicrobial mechanisms.

Summary: In this study, the dewatering performance of commercial polyethersulfone (PES) microfiltration (MF) membranes was evaluated using an integrated experiment and modeling approach. The effects of algae concentration, testing time, feed flow rate, and chemical cleaning on the dewatering performance and fouling-layer morphology were investigated. The fouling behavior was successfully described using the Hermia and gel layer models with a gel concentration of 48 g/L for algae solutions. Furthermore, hydrophilic zwitterions were grafted onto the PES membrane surface, which mitigated fouling.

Summary: Chiral plasmonic nanostructures have attracted attention for their strong optical response and superchiral near-fields. This study demonstrates that chiral cavity plasmon resonances can enhance the chiral optical response of film-coupled chiral Au helicoid nanoparticles. Furthermore, the chiral cavity mode can modulate the emission polarization of a point electric dipole, enabling the emission of circularly polarized photons. These findings provide a promising platform for advanced chiral optical devices.

Summary: Applying pressure is essential in synthesizing high-temperature superconducting hydrides. However, stabilizing the high-pressure phase of hydrides under ambient conditions is challenging. By modulating the charge transfer from metal atoms to hydrogen atoms, it is possible to maintain the dynamical stability of the hydride CaBH5 at pressures as low as 1 GPa. This new mechanism, called charge transfer modulated virtual high-pressure effect, enhances the structural stability and enables the reemergence of the forbidden [BH5](2)- anion, resulting in a strongly coupled superconductor CsBH5 with a transition temperature of 98 K.

Summary: We report an experiment that simulates the charging process of a XXZ Heisenberg Hamiltonian-driven quantum battery using single photons and linear optics. We find that entanglement is not always the most important resource for boosting charging, while coherence plays a significant role. We construct a two-qubit quantum battery and investigate the performance of quantum batteries and their relationship with the amount of entanglement and coherence during charging. Our findings offer insights for designing more efficient quantum devices and advance our understanding of quantum resources.

Summary: This paper presents a formalism for calculating response functions based on the generalized GW (GGW) method, which is applicable to electronic systems with spin-dependent interaction. The formalism automatically ensures the fluctuation-dissipation theorem (FDT) and is theoretically proven to respect the Ward-Takahashi identity (WTI). In contrast, the commonly used random phase approximation (RPA) violates both WTI and FDT within the GGW method, while the Bethe-Salpeter equation (BSE) satisfies WTI but not FDT. The validity of this formalism is demonstrated on the two-dimensional one-band Hubbard model, showing significant improvements over the RPA formula. With a computational cost similar to BSE, our formalism is expected to be applied to realistic materials.

Summary: This study evaluates the performance of a novel AOP ultraviolet/peracetic acid (UV/PAA) and conventional UV/hydrogen peroxide (UV/H2O2) through targeted PPCP analysis, Daphnia survivability and life history, and high-resolution mass spectrometry-based targeted lipidomics analysis. Both AOP treatments significantly decreased the concentrations of pharmaceuticals and personal care products (PPCPs) in wastewater. However, the UV/PAA AOP treatment showed a less significant decrease in toxicity compared to other treatments, resulting in slower growth, changes in lipid composition, and lower population increase in Daphnia.
