Solar-driven interfacial evaporation system is attracting intensive attention for harvesting clean water in the utilization of solar energy. To improve solar-driven performance better application, structuring a absorber with high solar-thermal conversion efficiency critical. Semiconductor materials stable and economic properties are good candidates as absorbers. Semiconductors narrow band gap have been proved to offer broad absorption spectrum applications photoelectricity photocatalysis....
The outbreak of coronavirus disease 2019 (COVID-19) has led to substantial infections and mortality around the world. Fast screening diagnosis are thus crucial for quick isolation clinical intervention. In this work, we showed that attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FT-IR) can be a primary diagnostic tool COVID-19 as supplement in-use techniques. It requires only small volume (∼3 μL) serum sample shorter detection time (several minutes). distinct...
Abstract This work proposes a coupled kinetic model to capture the spatiotemporal evolution behaviors of reactive species generated by grating-like dielectric barrier discharge (DBD) operated in flowing humid air. The incorporates zero-dimensional (0D) for filament and 0D or two-dimensional (2D) fluid afterglow region. is experimentally validated ozone measurements under different airflow rates power levels. With pseudo-1D plug flow approximation, spatial distribution obtained agrees well...
Hydrogen generation by electrocatalysis water splitting is considered as one of the most promising techniques to address energy crisis and environmental pollution. Highly efficient, low-cost, stable catalysts are crucial speed sluggish kinetics hydrogen evolution reaction (HER). Molybdenum disulfide has been be a substitute Pt-based materials, but its inherently low conductivity, finite active edge sites due thermodynamically basal plane, self-stacking agglomeration properties still impede...
The electrical breakdown of SF6 in the presence floating metal particles is facilitated by two key factors: role and nonlinear behavior high-pressure SF6. However, microscopic transient processes remain unclear, motivating this paper. Using 2D fluid models, we investigate streamer induced a linear particle under negative applied voltage. First, We identify characteristic double-end inception combined gap. Then, propose equivalent pulse (EPS) mechanism to explain particle's role. Two...
Abstract In this work, a surface-dielectric-barrier-discharge (SDBD) based flexible plasma film (FPF) was established and tested for in-situ surface disinfection. The discharge product mode (i.e., O3 NOx mode) controlled by the applied voltage verified in situ gas quantification. For disinfection, shows significantly higher bactericidal efficiency than mode, FPF achieves ~3.5 logs >6 of bacterial reduction with 3 5 minutes exposure respectively. underlying mechanism is investigated....
In the context of global climate change, wind power has received considerable attention as a significant clean energy source. Nevertheless, problem turbine blade downtime due to icing, which occurs in fall and winter seasons under conditions high humidity low temperature, remains an urgent that must be addressed. addressing this challenge, novel method pulsed liquid discharge shock wave de-icing been proposed, offering distinct advantages such reduced consumption expedited response times....
Compared with traditional methods, plasma sterilization has advantages of high efficiency, easy operation, and environmental protection. This may be more suitable for air sewage in specific spaces, such as hospitals, laboratories, pharmaceutical factories. However, the mechanisms are still relatively unknown, especially bactericidal activities. Knowledge processes provides guidance practical applications. For example, action mainly occurs during reaction period, treatment time can set based...
Abstract Plasma–liquid interactions play an important role in plasma‐mediated bacterial inactivation. Attenuated total reflectance Fourier‐transform infrared (FT‐IR) spectroscopy is employed to probe the molecular changes occurring Escherichia coli suspension during direct plasma treatment and subsequent after‐charge storage. The recorded spectra are correlated germicidal effect. Successive protein secondary structures DNA conformation observed. It found that spectral range around 1,345 cm...
COVID-19 is still pandemic in the world although it has lasted for more than two years, situ real-time disinfection of curved surfaces public places extremely urgent. A flexible plasma film based on surface dielectric barrier discharge proposed this study. In effect and influence curvature performance are studied. The results showed that could inactivate a variety pathogens. Specifically, 10 min treatment log reduction 3.10, 3.42, 3.03 Escherichia coli, Staphylococcus aureus, vesicular...
A novel Hydrodynamic Cavitation-Assisted Oxygen Plasma (HCAOP) process, which employs a venturi tube and oxygen injection, has been developed for enhancing the production utilization of hydroxyl radicals (·OH) in degradation organic pollutants. This study systematically investigated fluid characteristics discharge properties gas-liquid two-phase body tube.

An experiment was conducted to investigate the effect of dietary zinc (Zn) level on growth performance, Zn concentration, metalloenzyme activity, transporter 2 (ZnT2) mRNA abundance, metallothionein (MT) abundance and MT concentration in either serum or tissues, so as evaluate optimal broiler chicks fed a corn–soybean meal diet from 22 42 days age. At age, 288 birds were assigned randomly by bodyweight one eight treatments six replicate cages each with per cage, Zn-unsupplemented basal...
Conventional preformed particle gels suffer from insufficient salt tolerance and weak mechanical properties after water absorption, which reduce the shutoff effect in mature oilfields. In this paper, a nanocomposite gel (NCPG) is synthesized by copolymerization of acrylamide (AM) 2-acrylamido-2-methylpropane sulfonic acid (AMPS) using laponite RD (LPT) as physical cross-linker N,N-methylene-bisacrylamide (MBA) chemical via situ free radical polymerization. Compared with NCPG without LPT,...
