Abstract This study conducted an activation experiment on tap water using a self‐designed dielectric barrier discharge plasma field. Aged pepper seeds and seedlings were chosen as the investigation's subjects to assess plasma‐activated (PAW's) effects aged seed germination, seedling growth, their respective qualities. PAW cultivation led notable improvements in seeds' germination potential rate, with increases of 18.0% 28.3%, respectively. Moreover, vitality index exhibited remarkable rise...
Construction of a high-sulphur-loading electrode is an effective approach for achieving high-specific energy density in lithium-sulphur batteries. The polymer binder has important influence on the microstructural and electrochemical behaviours electrodes. In study, three commonly used binders, namely polyvinylidene fluoride (PVDF), polyacrylonitrile (LA133), polyacrylic acid (PAA), were with electrodes, their performance characteristics investigated. water-soluble binders LA133 PAA showed...
A self-consistent and complete numerical model for investigating the fundamental processes in a non-equilibrium thermal plasma system consists of governing equations corresponding physical properties plasmas. In this paper, new kinetic theory transport two-temperature (2-T) plasmas, based on solution Boltzmann equation using modified Chapman–Enskog method, is presented. This work motivated by large discrepancies between theories calculation 2-T plasmas proposed different authors previous...
Skin color enhancement based on favorite skin is proposed to make displayed large screen flat panel TVs agree with human color. A robust detection method in different intensity obtained after analyzing the distribution of HSV space. The region found via a psychological experiment too. Then detected enhanced degrees according distance between it and experimental result 60-inch plasma display (PDP) shows that colors are approached degrees. more natural comprehension vision psychology perceived advance.

The control signals switches generated by FPGA according setting parameters pulses loads sent via optical fiber. There remarkable...
Abstract Objectives To characterize the clinical features and to identify predictors of recurrence histiocytic necrotizing lymphadenitis (HNL) in Chinese children. Study design This study retrospectively analyzed characteristics, laboratory pathological findings, status children diagnosed with HNL at a single center China from January 2018 May 2023. Logistic regression analysis was employed recurrence. Results 181 histopathologically confirmed were enrolled (121 males 60 females). The mean...
ABSTRACT This study investigates the bidirectional effects of plasma‐activated water (PAW) on Botrytis cinerea . At low PAW concentrations, fungal growth was promoted, with spore multiplication reaching 54.46 ± 7.16% (PAW‐10) and mycelial at 4.88 1.83% (PAW‐2). However, higher effect shifted to inhibition, inactivation 41.99 8.58% (PAW‐30) 7.30 1.73% (PAW‐30). Critical thresholds for promotion inhibition were observed PAW‐18 PAW‐5, respectively. H 2 O + in promoted reproduction...
ABSTRACT A half‐bridge circuit formed by series‐connected silicon carbide metal‐oxide‐semiconductor field‐effect transistors (SiC MOSFETs) generates high‐frequency, high‐voltage pulses with a fast rising time, widely used in electro‐optical modulators. Inconsistencies the drive timing, variations device parameters, and parasitic parameters lead to non‐uniform switching behaviour among SiC MOSFETs, causing significant voltage stress disparities potential overvoltage breakdown under severe...
Micro-LEDs are one of the most promising candidates for next-generation displays, yet they inconvenienced by efficiency reduction induced sidewall defects when pursuing further scaled-down device dimensions. We have systematically investigated both size and temporal dependence micro-LEDs. Micro-LED arrays with a mesa ranging from 7 to 100 μm were prepared display purposes. The luminance external quantum (EQE) measured discussed. Surprisingly, micro-LED smaller exhibit higher EQE under ns...
