Summary: High aspect-ratio nanopores with nearly cylindrical geometry were fabricated by ion irradiation and etching, with the shape of the nanopores tapering towards the polymer surfaces. Using SAXS, the tapered structure was quantitatively measured, and it was found that the etch rates slightly decrease with increasing fluence. The observed nanopore shape was found to significantly influence the pore transport properties, with water flow rates being affected compared to cylindrical pores.

Summary: The study investigated the surface modification of polyethylene terephthalate track-etched membranes using planar magnetron sputtering of titanium and titanium dioxide thin films to improve hydrophilicity and photocatalytic activity. The deposited thin films showed reduced pore diameter and complex composition. Both Ti and TiO2-Ti sputtering significantly decreased water contact angle, enhancing membrane hydrophilicity and self-cleaning properties. This approach demonstrated effectiveness in improving porous polymeric support properties.

Summary: Nanovoids in polyamide layers significantly influence the roughness structures and water permeance of thin film composite (TFC) reverse osmosis (RO) and nanofiltration (NF) membranes. This study investigates water transport behaviors in a polyamide layer with or without nanovoids through numerical simulations and also develops an analytical model to quantify the competition between substrate-induced unfavorable funnel effect and nanovoid-induced favorable multi-effects. The modeling results demonstrate that even tiny nanovoids can minimize water transport distance and enhance the membrane permeance by 1-2 orders of magnitude.

Summary: We developed a method for preparing pH-responsive tracketched membranes using poly(ethylene terephthalate) (PET) for separating water-oil emulsions. The membranes showed hydrophobicity at pH 7-9, and pH-responsive behavior at pH 2 due to the protonated grafted layer of poly-4-vinylpyridine (P4VP). The membranes with controlled hydrophobic-hydrophilic properties successfully separated direct and reverse oil-water emulsions with a purification degree of 95-100%.

Summary: In this study, high-performance ZIF-8 @polycarbonate nanocomposite membranes with satisfactory structural stability for gas separation were reported. ZIF-8 nanoparticles with cubic morphology and controlled size were synthesized using the wet chemical method. Membranes with different concentrations of ZIF-8 filler were prepared using the solution casting method. The synthesized filler and membranes were characterized using various techniques, and gas separation measurements were taken using pure H2, CO2, and N2 gases. The results showed that the 15 wt% ZIF-8/PC nanocomposite membrane exhibited the highest H2 permeability, with an increment of 316.03%. The H2/CO2 and H2/N2 selectivity also showed significant improvements of 89.43% and 103.64%, respectively. Therefore, the PC/ZIF-8 system seems promising for the development of new H2 selective membranes with high gas permeability and selectivity values.

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.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
