Summary: The discrimination and quantitation of ammonia (NH3) exhaled from human beings using oxide chemiresistors has shown great potential for non-invasive and direct diagnosis of helicobacter pylori gastropathy and end-stage renal disease. A humidity-activated sensor employing AlOOH was designed and demonstrated, exhibiting high selectivity and response toward ppb-level of NH3 under 98 % humidity at room temperature. Enhanced adsorption of NH3 at abundant Bronsted acid sites and an effective ammonium ionic transmitting pathway induced by adsorbed moisture were proposed as the reasons behind the humidity-activated gas-sensing mechanism.

Summary: With the increase in agriculture intensity and the use of nitrogen-based fertilizers, nitrate pollution has become a problem in soils and waters. This study aimed to evaluate the sorption capacities of different activated carbons towards nitrate and analyze the effects of various parameters on their sorption capacities. The results showed that certain activated carbons had high sorption capacities and were influenced by contact time, solution pH, and the presence of co-existing anions. The study also identified the importance of feedstock and activation type in the sorption of nitrate and identified four materials with potential for nitrate retention in water-soil systems.

Summary: Batch kinetic experiments combined with XAS were conducted to investigate the sorption behavior of Mn-(II), Co-(II), Ni-(II), Zn-(II), and Cd-(II) with sulfated green rust (GR) in anoxic suspensions at pH 8. The results showed that all five divalent metals coordinated at Fe-(II) sites of the GR sorbent. However, there were differences in the sorption behavior, with Mn-(II) and Cd-(II) showing limited uptake and Co-(II), Ni-(II), and Zn-(II) exhibiting extensive sorption throughout the experimental time frame. This was attributed to differences in affinity and extent of substitution in Fe-(II) sites of the GR lattice controlled by ionic size.

Summary: This study evaluated a customized bead-type activated carbon (BAC) with surface modification options via amination for removing acetaldehyde (CH3CHO) from the atmosphere. Chemical and physical analyses showed that the amine and carboxylic acid groups on the surface of the modified BACs are critical in CH3CHO adsorption. Piperazine/nitric acid impregnation resulted in a superior performance in terms of CH3CHO adsorption, with greater chemical adsorption.

Summary: This study investigated the sorption of aqueous Mn(II) and Co(II) onto hexagonal birnessite under anoxic conditions. The results showed that the co-sorption of Mn(II) and Co(II) led to reduced sorption rates and extent. The presence of Mn(II) affected the transformation of birnessite and the speciation of Co(II). These findings indicate the significant impact of aqueous Mn(II) on the reactivity and solubility of Co(II) in geochemical environments.

Summary: A novel Mn(II) encapsulated mesoporous silica nanoparticles (Mn-MSNs) were developed for efficiently removing antibiotic tetracycline from aqueous solutions. The Mn-MSNs showed a large specific surface area and maximum sorption capacity, with the dominant mechanism for tetracycline sorption being Mn-O complexation. The materials also exhibited good regeneration property over repeated sorption-desorption cycles, making them promising for cost-effective applications in sequestrating tetracycline from wastewater, drinking water, and contaminated solutions.

Summary: The goal of this study was to develop new biocomposite films that can better protect and prolong the shelf life of food. A ZnO: eugenol@yam starch/microcrystalline cellulose (ZnO:Eu@SC) antibacterial active film was constructed, which effectively improved the physicochemical and functional properties of composite films by utilizing the advantages of metal oxides and plant essential oils. The addition of an appropriate amount of nano-ZnO improved the film's compactness, thermostability, moisture sensitivity, mechanical properties, and barrier properties. ZnO:Eu@SC exhibited good controlled release of nano-ZnO and Eu in food simulants, and the antimicrobial activity was significantly enhanced after loading Eu.
