Summary: In this study, four diethyl alpha-aminophosphonate derivatives were synthesized by reacting (3-aminophenyl)boronic acid pinacol ester with different aromatic aldehydes and diethyl phosphite. The compounds showed high thermal stability and good friction properties for rapeseed oil at low concentrations. Among them, BNP3 exhibited the best friction-reducing and anti-wear performances due to the strong electron withdrawing ability of the nitro group. This suggests potential industrial applications of these derivatives as lubricant additives.

Summary: Management of type 2 diabetes mellitus using DPP IV inhibitors is important, but current inhibitors have side effects. This study investigates the effect of new boronic acid-based thiazole compounds as DPP IV inhibitors. Two boronic acid-based molecules, PC06R58 and PC06R108, show potent DPP IV enzyme inhibition and significantly reduce blood glucose levels in rats. These compounds have satisfactory DPP IV inhibition and show promise as lead compounds in this novel class of DPP IV inhibitors.

Summary: We report anomalous glucose-responsive gelation/solation behavior in 3-aminophenylboronic acid-modified hyaluronic acid. Gelation occurred at glucose concentrations of 5-20 mM, forming crosslinks via glucose that could reversibly bind to the two boronic acid sites. Solation was induced at glucose concentrations of >80 mM.

Summary: In this study, PIL@TiO2 composites with varying concentrations of polymerized ionic liquid were evaluated for their pollutant degradation activity towards benzene and toluene. The results showed that PIL (low)@TiO2 composite exhibited higher activity than PIL (high)@TiO2 composites, with further enhancement achieved by incorporating graphene oxide (GO) to increase efficiency. The novel hybrid photocatalyst (PIL@TiO2/m-GO) demonstrated excellent performance in degrading benzene (97%) and toluene (97%), with an ultimate bandgap of 2.1 eV.

Summary: The study presented an efficient and eco-friendly soil stabilization method using a water-soluble acrylic acid-acrylic amide copolymer and an epoxy system. The combination significantly increased the unconfined compressive strength (UCS) of the stabilized soil, with the lowest apparent density (AD) and highest UCS observed in the soil treated with both the copolymer and epoxy system. The roles of the copolymer and epoxy system in enhancing UCS were attributed to the formation of an interpenetrating polymer network (IPN).

Summary: Currently, various advanced methods are being used in gas sensing and monitoring, including detecting hazardous gas leaks and monitoring ambient air. Commonly used technologies include photoionization detectors, electrochemical sensors, and optical infrared sensors. However, these sensors, which are nonselective or semiselective, can be affected by unwanted analytes. To address this issue, gas separation and discrimination technologies such as gas permeable membranes, metal-organic frameworks, microfluidics, and IR bandpass filters have been developed. Although these technologies have not been extensively utilized in the field for vapor intrusion monitoring, they show promise for further development and application. This review provides an overview and summary of the existing gas separation and discrimination technologies for popular gas sensors used in environmental applications.
