Summary: Membrane separation is an effective method for treating oily wastewater. This study improved the efficiency of oil-in-water emulsion separation by using alkali treatment to promote the deposition of Fe (III) on PVDF membranes. A hydrophilic coating was also produced on the membrane surface, enhancing permeability and antifouling properties. The modified membrane showed excellent pure water flux and oil rejection, as well as underwater anti-oil adhesion and antifouling properties. This environmentally friendly PVDF membrane modification strategy has great potential for oil-in-water emulsion separation.

Summary: Developing flexible electromagnetic interference (EMI SE) shielding materials is crucial for protecting humans from harmful radiation. We designed and fabricated a flexible multilayer structure of PVDF/GNP-PVDF composite film, which exhibited high EMI SE performance (averaging 69.7 dB in X-band), excellent flexibility, and stability (98.85% retention after bending 1000 cycles at 60 degrees). The theoretical study indicates that the multiple reflection and absorption of electromagnetic waves between layers contribute to the high EMI SE performance of the PVDF/GNP-PVDF multilayer film.

Summary: This study focuses on the development of hybrid ultrafiltration membranes using Poly(vinylidene fluoride) (PVDF) with zeolitic imidazolate framework-8 (ZIF-8) nanocrystals. The study investigates the surface morphology and distribution of ZIF-8 in the PVDF matrix, as well as its antibacterial activity and chemical functionality. The addition of ZIF-8 enhances the hydrophilicity and porosity of the membranes, resulting in increased pure water permeability and improved rejection and permeate flux for bovine serum albumin (BSA) and humic acid (HA). The PVDF hybrid membrane with 2 wt% of ZIF-8 demonstrates excellent permeability, antifouling, and antibiofouling abilities, making it a promising choice for water treatment applications.

Summary: In this study, two amphiphilic di-block copolymers were synthesized and characterized, and their critical micelle concentrations (CMC) in toluene were determined. It was found that the CMC of the synthesized copolymers decreased with increasing temperature and PMMA chain length. Thermal analysis also showed that the degradation temperature of the copolymers slightly increased with increasing PMMA chain length, possibly due to the hindered diffusion of thermal energy across the entangled chains of PMMA.

Summary: The study shows that Chinese theaters exhibit revenue fluctuations due to variations in seating capacity and number of auditoria, with larger seating capacity and higher capacity utilization rates playing a significant role in revenue gains, while price differences have minimal impact. Additionally, many Chinese theaters have significant deviations in the number of auditoria and seats per auditorium, likely explained by the long-term, irreversible, and risky nature of theater design choices.

Summary: Lead halide hybrid perovskites have been extensively studied as light-harvesting materials due to their unique optoelectrical characteristics and easy deposition method. However, toxicity and stability issues have hindered their further development. In this study, stable lead-free Cs2AgBiBr6 single crystals with excellent photoelectric properties were prepared. Symmetric Au electrodes resulted in photodetectors with broad spectral response, high responsivity, external quantum efficiency, and detectivity. Interestingly, asymmetric electrodes (Au and Ag) led to the development of the first self-driven photodetector based on the lead-free perovskite single crystals, showing good photoresponse properties at 0 V bias. Both devices demonstrated short response times at the microsecond scale and good stability without encapsulation, indicating great potential for optoelectronic device applications.
