This study shows that the atmospheric cold plasma jet is capable of curing fungus-infected plant leaves and controlling spread infection as an attractive tool for disease management. The healing effect was significantly dependent on size black spots infected with fungal cells leaf age. diameter <2 mm can completely recover from state. plasma-generated species passing through microns-sized stomas in a weaken function oil vacuoles cell membrane cells, resulting plasma-induced inactivation.
Nonthermal plasma has been widely considered as an effective method for bacterial inactivation in food safety. In this paper, the preservation of fresh beef was investigated using plasma-activated water (PAW) with different treatment time intervals ranging from 6 to 192 h. The effects PAW on were evaluated microbial counts surface and its quality attributes. bactericidal efficiency found be strongly dependent storage time. Results show that 24-h could achieve a reduction around 3.1 log...
Recently, plasma-activated water (PAW) has received extensive attention in food safety field due to its advantages of eco-friendly and high sterilization efficiency. In this paper, the effects PAW on microbe loads quality fresh-cut kiwifruit (FCK) were studied, preservation mechanism FCK was explored. A 1 mL sterile as control sample separately sprayed stored at 4 °C for 8 days. Compared sample, microbial population reduced by approximately 1.8 log CFU/g after treatment. The activities...
ABSTRACT Atmospheric-pressure N 2 , He, air, and O microplasma arrays have been used to inactivate Escherichia coli cells suspended in aqueous solution. Measurements show that the efficiency of inactivation E. is strongly dependent on feed gases used, plasma treatment time, discharge power. Compared atmospheric-pressure He arrays, air may be utilized more efficiently kill The efficiencies water can well described by using chemical reaction rate model, where reactive oxygen species play a...
Plant diseases resulting from plant pathogens are profoundly affecting crops worldwide. In this study, the tomato pathogen Cladosporium fulvum ( C. ) have been inactivated by using atmospheric‐pressure plasma jet (APPJ). The results show that inactivation efficiencies of dependent on density and treatment time. APPJ with a relatively high can completely kill resistant within time 60 s. Due to generating electrostatic force, outer membrane is disrupted cytoplasm released surrounding medium....
Abstract We report a plasma‐assisted CO 2 hydrogenation to CH 3 OH over Fe O /γ‐Al catalysts, achieving 12% conversion and 58% selectivity at temperature of nearly 80°C atm pressure. investigated the effect various supports loadings Fe‐based as well optimized reaction conditions. characterized catalysts by X‐ray powder diffraction (XRD), hydrogen programmed reduction (H ‐TPR), desorption (CO /CO‐TPD), high‐resolution transmission electron microscopy (HRTEM), scanning (STEM), x‐ray...
Leymus chinensis, a major component of the plant community in eastern Eurasian grasslands with wide distribution, provides stability to grassland ecosystems and supports animal husbandry. This study aimed bridge gap between molecular breeding industrial application L. chinensis by conducting comprehensive simple sequence repeat (SSR) analysis. A total 973,129 SSRs were identified whole genome, which was used design 20 polymorphic pairs SSR primers further assess 105 accessions. On average,...
It remains a challenge to generate the uniform and large-area cold plasma at atmospheric pressure. In this paper, we report method reliable homogeneous brush-shaped plume running The brush (110 mm in length 10 width) is mainly composed of well-aligned hollow optical fibers. Current-voltage measurements indicate that consists glowlike pulsed discharge with their pulsewidths several microseconds. generation He/O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML"...

He about 1% O 2 was found entirely kill resistant treatment time min. Measurements optical emission...
At temperatures above 350 degrees C, significant amounts of NOx formed from N2 and O2 have been observed in Cu-ZSM-5 catalyst-pellet filled dielectric barrier discharges, indicating the necessity using low-temperature performance all plasma-catalytic processes for removal air pollutants.
We report on the generation and confinement of atmospheric-pressure microplasmas inside 100-to-2000-μm-inner-diameter (i.d.) hollow-core fibers (HCFs) filled with helium gas. The microplasma propagation these 10-cm-long HCFs results from anode-driven pulse discharges their durations 30 ns–15 μs. current density generated at an i.d. 100 μm is about four magnitudes higher than glow-like one 2000 μm. Analysis shows that high can be explained by mechanism small values low surface recombination rate.
