Summary: The KCl-modulated swelling behavior of double thermoresponsive diblock copolymer(DBC) thin films and their subsequent responsive behavior in a D2O atmosphere are investigated using spectral reflectance (SR), in situ time-of-flight neutron reflectometry (ToF-NR), and Fourier-transform infrared (FT-IR) spectroscopy. The addition of KCl to the DBC thin films increases their swelling ratio and D2O content during vapor treatment. The films further swell and reach a maximum thickness before contracting upon subsequent heating. Two separate volume phase transition temperatures (VPTTs) are observed, which correspond to a further swelling plateau and the start of contraction. KCl reduces the VPTTc of the PNIPMAM blocks and forms an enrichment layer in the film during heating.

Summary: Insulin therapy is the most effective way to control blood glucose in diabetic patients, and subcutaneous injection is the most effective administration route. Chitosan poly-acrylic acid nanobubbles were developed as drug carriers for insulin, achieving visually controlled pulsatile release triggered by focused ultrasound. The release of insulin from nanobubbles could be accurately controlled under ultrasound guidance, significantly reducing the injection frequency of insulin.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. 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.
