Summary: This study enriched a group of high efficiency urease bacteria (UF1) and loaded it on the surface of scoria to synthesize a novel microbial adsorbent (Scoria@UF1) for adsorbing Pb2+ and Cd2+ ions in contaminated water. The adsorption behavior of Scoria@UF1 for Pb2+ and Cd2+ was consistent with Langmuir isothermal model and showed the pseudo-first-order adsorption kinetics model. Additionally, the study confirmed that the UF1 community mainly consisted of Proteobacteria and Firmicutes, and the addition of Pb2+ and Cd2+ ions decreased the community diversity of UF1.

Summary: Lead (Pb) is a common public hazard in drinking water, often derived from mining, batteries, and dye manufacturing waste. Capacitive deionization (CDI) technology is considered a potential alternative for efficient capture of Pb ions due to its operational convenience, environmental-friendliness, and low cost. In this study, nitrogen-doped carbon nanotube encapsulated Fe7S8 nanoparticles (Fe7S8@NCNT) were prepared for the pseudocapacitive removal of Pb2+ ions, showing excellent pseudocapacitance and enhanced CDI performance compared to other materials. This research suggests that Fe7S8@NCNT could be a promising cathode for removing heavy metal Pb2+ ions from water, with high selectivity and competitive performance in practical applications.

Summary: The application of insulation materials with high-performance heat-blocking properties such as nano-structured insulations like aerogels and graphite polystyrene is essential in buildings and vehicles. This paper presents a comprehensive thermal characterization of fibrous aerogels (slentex, pyrogel) and graphite-expanded polystyrene to compare their thermal insulation capability. The surface analysis of the samples is conducted through microscopic and wetting experiments, and the results of thermal conductivity and specific heat capacity measurements for both individual and sandwich structures are shown. The slentex aerogel has the best thermal conductivity, while the hybrid structures show promising results. The pyrogel aerogel exhibits the highest moisture uptake. The results of infrared absorption tests and differentiated scanning calorimetry confirm the high infrared absorption of graphite polystyrene.

Summary: Heavy metal pollutants are highly toxic and pose great concern in environmental monitoring. Electrochemical detection, hindered by mutual interferences of heavy metal ions, is a main technique with limited sensitivity to Cd2+ ions. This study introduces a metal-free and sustainable nanomaterial, cysteamine covalently functionalized graphene (GSH), which significantly enhances the sensitivity of screen-printed carbon electrode (SPCE) to Cd2+ ions while maintaining sensitivity to other heavy metals. The enhancement is attributed to the grafted thiols on the GSH sheets with strong affinity to Cd2+ ions, based on Pearson's principle. The GSH-modified SPCE also exhibits high reusability and outperforms existing SPCEs modified by non-covalently functionalized graphene derivatives. The GSH-SPCE is successfully validated in tap water.
