Summary: In this study, two metastable reconstruction states with distinct stacking orders and strain soliton structures were identified in small-angle twisted graphene using conductive atomic force microscopy. The switching mechanism between these two states was found to propagate spontaneously in a domino-like fashion. The fine structure of the bistable states is critical for understanding the unique properties of van der Waals structures with tiny twists.

Summary: Multilayer dielectric (MLD) gratings with high diffraction efficiency and a high laser-induced damage (LID) threshold are crucial for pulse compressors in chirped pulse amplification lasers. However, surface defects introduced in the manufacturing process can decrease the LID resistance of MLD gratings and affect laser output. In this study, a dynamic model is used to investigate the impact of defects, such as nodules, particle contaminants, and cracks, on the LID threshold of a MLD grating design using a 20-fs near-infrared (NIR) laser pulse.

Summary: This study investigates the influence of molecular weight (Mw) on the performance of polyelectrolyte multilayer (PEM) membranes. The results show that Mw has different effects on the performance of different types of PEM membranes, especially for systems with higher polyelectrolyte (PE) mobility. Specifically, low-Mw PEM membranes exhibit the performance of a negatively charged separation layer, while high-Mw PEM membranes exhibit the performance of a positively charged separation layer. Additionally, low-Mw PEM membranes are denser than high-Mw PEM membranes. The pH stability of low-Mw PEM membranes is poorer, which may be attributed to their higher mobility.

Summary: The effects of plasma treatment time on the gas permeation and pervaporation dehydration properties of organosilica membranes were investigated. The study found that increasing plasma modification time resulted in a decrease in pore size, leading to an increased He/N2 permeance ratio. The H2O/EtOH permeance ratio also increased from about 20 to over 1000 as the plasma modification time increased due to changes in pore structure and water adsorption properties.

Summary: The study systematically investigated the influence of charge density and ionic strength on the performance of nanofiltration membranes, revealing that low charge density limits polyelectrolyte adsorption and retention, while high charge density affects membrane surface charge and pure water permeability. Increasing ionic strength is crucial for high charge density polyelectrolytes, but has an opposite effect on membrane properties depending on the type of polyelectrolyte used.

Summary: In this paper, the local electric field (LEF) characteristics of a multilayer silver nanoparticle were studied through simulations. It was found that increasing the layers improved the LEF intensity on the glass support, while only two layers were required on the gold film support to achieve the maximum LEF intensity. Experimental results confirmed the simulation findings. The optimized 2-layer silver nanoparticle@gold film exhibited high SERS sensitivity and signal uniformity, with a detection limit of 1 x 10(-15) M for Rhodamine 6G and a relative standard deviation of 11% for the signal intensity.

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.
