Subsequently, comprehensive studies have been conducted analyze effect various patterns...
For the further development of sodium-ion batteries (SIBs), it is very important to research and develop low-cost high-performance anode materials. Though hard carbon has high theoretical capacity for SIBs, nevertheless, in practical applications, presents low conductivity, poor electrochemical stability, slow kinetics. In this research, a N-doped biomass carbon/reduced graphene oxide (NC/RGO) composite facilely constructed by pyrolyzing cellulose, chitosan, GO. The NC/RGO shows highly...
Raman spectroscopy with the advantages of in situ and simultaneous detection multi-components has been widely used identification quantitative gas. As a type scattering spectroscopy, sensitivity is relatively lower, mainly due to low signal collection efficiency. This paper presents design assembly multi-channel cavity-enhanced system, optimizing structure sample pool reduce loss laser increase excitation intensity signals. Moreover, three channels are collect signals efficiency for...
A two-level model of tunneling magnetoresistance (MR) containing coplay the relative orientation moments between clusters, intrinsic characters and Coulomb blockade effect, is presented. Based on Monte Carlo simulation, spin configurations, MR resistivity as function temperature field were studied, respectively. Simulated results are found to be in good agreement with recent experimental data. The unusual enhancement attributed interaction clusters character clusters. Although effect plays...
Background: Increasing bacterial infections as well a rise in resistance call for the development of novel and safe antimicrobial agents without inducing resistance.Nanoparticles (NPs) present some advantages treating provide an alternative strategy to discover new antibiotics.Here, we report self-assembled fluorescent organic nanoparticles (FONs) with excellent antibacterial efficacy good biocompatibility.Methods: Self-assembly...
Tool condition is crucial for guarantee processing efficiency and surface quality. However, the complex industrial environment, limited computational conditions, less training data present a challenge to accuracy of tool monitoring. This paper introduces lightweight deep learning method that achieves highly accurate end-to-end image segmentation wear, thereby reducing complexity memory consumption. To reduce model parameters, axial Depth-Wise (DW) convolution used, which combines...
Abstract Distributed photovoltaic power generation has become the key development direction of new energy in future, but a large number distributed sources connected to grid will have significant impact on quality and state. In response above-mentioned issues, method accessing capacity supply, taking into account state analysis, is proposed improve system voltage stabilize it, reduce network loss distribution network. The with different access capacities chain investigated by calculating...
Abstract Fossil fuel dependence causes environmental and resource issues, intensified by climate change population growth. Renewable sources like solar, wind, biomass are rising. Biomass contributes 10–14 % of global energy, with gasification offering stable output useful byproducts. However, efficiency concerns challenge its economic viability, prompting the need for predictive models under diverse conditions. This study introduces a novel hybrid modeling approach that integrates Naive...
Work functions of NiPt alloys with different compositions are investigated using first-principles methods based on density-functional theory. Results our calculations reveal that surface alloy composition has a significant effect the work function alloy. However, for given composition, is insensitive to distributions Ni/Pt atoms in and it only slightly affected by disorder. Our suggests atomic modification as promising way tuning metal gate.
Solid-state electrolytes with high ionic conductivity, excellent interfacial stability, and fast charge transport are desired for next-generation high-energy-density lithium–metal batteries. Herein, an in situ three-dimensional (3D) composite polymer electrolyte (CPE) is designed fabricated by a simple solidification of poly(ethylene oxide) (PEO) solution precursor 3D TiO2 backbone on the cathode. The CPE not only shows very stable structure conductivity but also exhibits impressive...
Streptococcus suis ( S. ) is an important food-borne zoonotic pathogen that causes swine streptococcosis, which threatens human health and brings economic loss to the industry. Three-quarters of infections are caused by serotype 2. A retrospective analysis cases in Shenzhen, a megacity China, with high pork consumption, between 2005 2021 was conducted understand its genomic epidemiology, virulence, drug resistance characteristics. The epidemiological investigation showed Shenzhen were mainly...
Work functions of sub- and monolayers Mo on metal Ta various orientations are investigated using first-principles methods based density functional theory. The calculated results reveal that the work function has strongly orientation dependence. However, for a given surface orientation, is insensitive to distributions Ta/Mo atoms in layer. Moreover, it found (100) (111) surfaces increase with increasing composition layer but those (110) decrease. By analysis dipole density, mainly determined...

We theoretically put forward a spin injector, which consists of three-terminal ferromagnetic-metal (FM) nonmagnetic-semiconductor (NS)-superconductor (SC) mesoscopic hybrid system. This device can inject not only the spin-up current but also pure into NS lead. The crossed Andreev reflection plays key role in this device. Such injector may be realized within reach present-day technology.
Varicella (chickenpox) is a highly transmissible childhood disease. Between 2010 and 2015, it displayed two epidemic waves annually among school populations in Shenzhen, China. However, their transmission dynamics remain unclear there no school-based vaccination programme Shenzhen to-date.
