Abstract Transient devices represent an emerging type of electronics whose main characteristic is the constituent materials that could fully or partially dissolute disintegrate by chemical physical processes after completing mission, and are considered as new research directions for implantable devices. However, on transient still in its infancy there many challenges to overcome, especially development energy relatively slow. Here, implantable, biodegradable zinc ion battery (TZIB) assembles...

Separation of impurities (CO2 and N2) from CH4 is an important issue for natural gas alternatives (such as coalbed gas, biogas, landfill gas) upgrading. It notably challenging to synthesize high N-doped porous carbon with appropriate structure. In this work, N content (14.48 wt %) micropore size 0.52 1.2 nm specific surface area 862 m2 g−1 has been synthesized potassium hydroxide (KOH) activated waste wool upon the urea modification. Pure component adsorption isotherms CO2, CH4, N2 are...

Abstract Hard carbons are widely studied as anode materials for sodium‐ion batteries (SIBs) due to their high Na‐storage capacity, long cycle life, and low cost. However, the initial coulombic efficiency (ICE) poor performance remain bottleneck concerns that necessitate a comprehensive material engineering solution. Herein, we propose facile strategy synthesize amorphous with pseudo‐graphitic dominated crystalline, expanded interlayer spacing, reduced surface defects via carbonization of...

With the vigorous development of electronics and increasingly prominent problem environmental pollution, it is particularly important to exploit environmentally friendly electronic devices. Transient represent a kind device that once specified functions have completed can completely or partially disappear through physical chemical actions. In this work, we introduce novel guar gum-cellulose aerogel (GCA) membrane based on natural biomaterials successfully use as an electrolyte film fabricate...

The development of functional materials that can detoxify multiple chemical warfare agents (CWAs) at the same time is great significance to cope with uncertainty CWA use in real-world situations. Although many catalysts capable detoxifying CWAs have been reported, there still a lack effective means integrate these catalytic-active on practical fibers/fabrics achieve protection against coexistence variety CWAs. In this work, by combination electrospinning and situ solvothermal reaction,...

Tobacco bio-oil, gases, and char were produced through pyrolysis of tobacco leaves using a fluidized bed pilot plant under varying temperature (350, 400, 450, 500, 550, 600 °C) residence time (5, 10, 17 s) conditions. The optimized condition for the production bio-oil was found to be at 500 °C vapor 5 s, giving yield 43.4%. Colorado Potato Beetle (CPB) Leptinotarsa decemlineata L. (Coleoptera: Chrysomelidae), destructive pest toward potato crops, three microorganisms (Streptomyces scabies,...

Ferroelectric-dielectric superlattices have attracted renewed interest for their ability to frustrate the polar order, leading emergence of exotic textures. The electrostatic depolarization, thought be responsible complex textures in these superlattices, can alleviated by replacing dielectric layer with a metallic one. One would thus expect that close uniform polarization state recovered ferroelectric layer. However, here we show, using density-functional theory calculations, metastable...

The wide band gap semiconductor Ga2O3 has been well studied in terms of the Schottky diodes. Controlling barrier height (SBH) Ga2O3/metal contacts is essential for achieving desirable, high-performance electronic devices. In this article, based on first-principles calculations, we effect inserting a two-dimensional dielectric layer hexagonal boron nitride (h-BN) SBH Ga2O3/metal. Two sets interface models with and without BN interlayer, i.e., Ga2O3/Au, Ga2O3/BN/Au, Ga2O3/Mg, Ga2O3/BN/Mg...

Sulfur adsorption and poisoning of Pt-based catalysts cause an undesired, detrimental effect on performance proton exchange membrane fuel cells. Here, WOx is adopted for the first time to modify such noble metal with aim acquiring excellent sulfur tolerance, due its unique nature hydrophilicity, redox couple in lower valence, as well spillover effect. A series WOx–Pt/C various contents tungsten oxide from 1 50 wt% were synthesized compared conventional Pt/C toward resistance using cyclic...
