Schematic illustration of reflective and heat insulation coatings for passive cooling.

In this research, a modified ammonium ion selective membrane was developed by surface modification and synthesis of an antimicrobial material using silver nanoparticles (AgNPs) anchored on two-dimensional transition metal carbides (Ti3C2Tx MXene). This material can be used as a carrier to avoid the release of AgNPs. The inorganic antimicrobial agent AgNPs@MXene was adhered to the surface of the ammonium ion-selective membrane by polydopamine, forming an antimicrobial coating. Amended ammonium ion selective electrodes enhance electrode production and usage by improving response times and lowering detection limits, thereby reducing costs and streamlining ammonia nitrogen detection and maintenance expenses.

An-amino functionalized microporous polymer, with abundant micropores (V_mic = 0.359 cm³ g⁻¹) and higher BET-specific surface area of 866 m²/g, shows a promising CO₂ uptake of 1.86 mmol/g at 273 K and 1.23 at 298 K and 1 bar. The polymer with CO₂-philic NH₂ groups can selectively capture CO₂ over N₂ and CH₄.
