A graphitic C<sub>3</sub>N<sub>4</sub> bilayer can stabilize polysulfides (PSs) by using a micropore-scale interlayer as promising anchoring material, and improve sulfur utilisation.
The Co@C 2 N monolayer could alleviate the shuttling of high-order polyselenides and promote reaction kinetics for high-performance Li–Se batteries.
Reasonable control of the pore sizes supercapacitor electrode materials ensures desolvation electrolyte ions to significantly improve capacitance.
Carbonaceous materials with pores or bilayer spaces are a kind of potential host material to confine polyselenide diffusion and mitigate the shuttling effect. In present work, theoretical design C2N (bi-C2N) as an efficient for lithium-selenium (Li-Se) batteries was explored by first-principles calculations. AA- AB-stacking could alleviate dissolution high-order polyselenides through synergistic effect physical confinement strong Li-N bonds. Lithium prefer anchor on instead commonly used...
Supercapacitors have a wide range of applications in high-technology fields. The desolvation organic electrolyte cations affects the capacity size and conductivity supercapacitors. However, few relevant studies been published this field. In experiment, adsorption behavior porous carbon was simulated with first-principles calculations using graphene bilayer layer spacing 4-10 Å as hydroxyl-flat pore model. reaction energies quaternary ammonium cations, acetonitrile, cationic complexes were...
The utilization of lithium–sulfur battery is hindered by various challenges, including the “shuttle effect”, limited sulfur utilization, and sluggish conversion kinetics lithium polysulfides (LiPSs). In present work, a theoretical design for viability graphitic carbon nitride (g-C3N4) phosphorus-doping substrates (P-g-C3N4) as promising host materials in Li-S was conducted utilizing first-principles calculations. PDOS shows that when P atom introduced, 2p N affected orbital atom, which...

In recent years, reverberation chamber testing technology has been rapidly developed. This paper focuses on the test principle and differences in electromagnetic compatibility (EMC) methods between anechoic automobile industry. It selects several different samples, performs comparison verification respectively, analyzes feasibility, adequacy, effectiveness of that can be promoted future.
To investigate how phosphorus-doped carbon micropores can significantly enhance the capacitance of electrochemical double-layer capacitors (EDLCs), we performed first-principles calculations on monolayer (MGP) and bilayer graphene (BGP-x, x = 4–8), simulating macropores or mesopores micropores, respectively. In addition, studied stable structure, relative capacitance, reaction characteristics Na+, Li+, their hydrated ion structures {[Na(H2O)n]+, [Li(H2O)n]+, n 1–4} MGP, as well insertion...
The metal foils at micrometer scale are applied in micro-electromechanical systems (MEMS) and devices widely, which the mechanical behaviors of them significantly different from that bulk materials thin films constrained by a substrate. In this paper annealed polycrystalline Cu foil with two thickness ( t =100, 150 μm) was on cantilever beam bending fatigue testing as model material. properties damage total strain control investigated. results showed life grain size d =9.2 larger than =3 μm...
