Abstract Electrochemical synthesis of NH 3 is a carbon‐free alternative to the traditional Haber–Bosch process. Obtaining from environmental pollutants, such as nitrates or nitrites, more practical route than nitrogen reduction reaction (NRR) due difficult cleavage inert triple bond gas. Here, novel heterogeneous catalyst reported based on iron (Fe) single‐atoms supported 2D MoS 2 (Fe‐MoS ) for nitrate (NO RR). Fe‐MoS exhibits remarkable performance with maximum Faradaic efficiency 98% NO RR...
Poor selectivity is a common problem faced by gas sensors. In particular, the contribution of each cannot be reasonably distributed when binary mixture co-adsorbed. this paper, taking CO2 and N2 as an example, density functional theory used to reveal mechanism selective adsorption transition metal (Fe, Co, Ni, Cu)-decorated InN monolayer. The results show that Ni decoration can improve conductivity monolayer while at same time demonstrating unexpected affinity for binding instead CO2....
The conversion of CO2 into desirable multicarbon products via the electrochemical reduction reaction holds promise to achieve a circular carbon economy. Here, we report strategy in which modify surface bimetallic silver-copper catalyst with aromatic heterocycles such as thiadiazole and triazole derivatives increase hydrocarbon molecules. By combining operando Raman X-ray absorption spectroscopy electrocatalytic measurements analysis products, identified that electron withdrawing nature...
Graphene oxide (GO), as an ultrathin, high-flux, and energy-efficient separation membrane, has shown great potential for CO2 capture. In this study, using molecular dynamics simulations, the of N2 through interlayer gallery GO membranes was studied. The preferential adsorption in channel derived from their strong interaction is responsible selectivity over N2. Furthermore, influences spacing, oxidization degree, length on CO2/N2 were investigated. Our studies unveil underlying mechanism...
The main purpose of this research is to provide a theoretical foundation for the screening drought-resistant soybean varieties and establish an efficient method detect PSII actual photochemical quantum yields efficiently. Three were compared in experiment after 15 d when they planted greenhouse. These then exposed light drought stress (LD) serious (SD) conditions. With five times' measurement, chlorophyll fluorescence soil-plant analysis development considered as basis study. Several...
Abstract The synthesis of a polymer that combines the processability plastics with extreme rigidity cross-linked organic networks is highly attractive for molecular sieving applications. However, are typically insoluble or infusible, preventing them from being processed as plastics. Here, we report solution-processable conjugated microporous thermoset permanent pores ~0.4 nm, prepared by simple heating process. When employed two-dimensional membrane hydrogen separation, exhibits ultrahigh...

The CO2 reduction reaction (CO2RR) using a renewable energy source is promising strategy for its utilization. Such technology, however, requires the development of catalysts with optimized activity and selectivity that can be integrated into device architectures. Flow electrolyzers have recently been proposed facilitating electrochemical CO2RR thanks to their unique ability perform electroreduction at high rates via creation three-phase interface. While some examples flow conversion...
Hookworm is highly endemic to Hainan Province, an island located in the South China Sea. To investigate prevalence and intensity of infection area, village Xiulongkan was surveyed between April July 1998. A cross-sectional study conducted which fecal samples 80% residents (631 individuals) were tested for presence helminth eggs. predominant intestinal Xiulongkan, where it determined that 60% those infected. Necator americanus species hookworm this population. The increased with age, then...
Abstract Membrane separation technology has found widespread application in molecular sieving and water reclamation. Its use organic solvent nanofiltration (OSN) been limited by the modest permeation rates stability of existing membranes. In this study, 2D clay nanolaminated membranes are engineered, derived from stacking exfoliated vermiculite nanosheets, as a potential solution for OSN. The as‐synthesized membrane displayed both solvents due to rapid hydration or solvation nanosheets. To...
