Grain growth and strain release processes in the electrodeposited nanocrystalline (nc) Cu specimen with a high purity were investigated by means of differential scanning calorimetry, x-ray diffraction, electrical resistance measurement, high-resolution transmission electron microscopy. It was found that for as-deposited nc Cu, grain started at about 75 °C, which microstrain (111) plane (e111) began to release, while mean (100) (e100) higher temperature (150 °C). With an increment introduced...
Based on MnO2/carbon cloth (CC) composite materials, an Ag-doped MnO2 nanowire, self-assembled, urchin-like structure was synthesized in situ the surface of CC using a simple method, and novel efficient flexible electrode material for supercapacitors developed. The morphology, structure, elemental distribution, pore distribution were analyzed SEM, TEM, XRD, XPS, BET. electrochemical performance tested cyclic voltammetry (CV) galvanostatic charge/discharge (GCD). In three-electrode system,...
Thin film reactions of Cu/Al multilayer films were investigated by differential scanning calorimetry and transmission electron microscopy. Sequential intermetallic compound formation was found in the temperature range from 300 to 620 K. With excess copper present as-deposited trilayer films, observed sequence CuAl2 Cu9Al4, interfacial controlled grain boundary diffusion. The activation energies for Cu9Al4 are 0.78±0.11 0.83±0.2 eV, respectively.
Structural design constitutes one of the crucial approaches for augmenting wave-absorbing capacity electromagnetic wave (EMW) absorbers, and incorporation cavity structures represents a typical methodology therein. In this work, MoS2-coated metal-organic framework (MOF)-derived Hollow-MoS2@CNS@CoS2 composite materials (HCNSs) were prepared by combining tannic acid-protected etching, carbonization, hydrothermal methods. Especially, HCNS700, which possessed both hollow structure layered...
This study investigated the effect of different monomer compositions acrylonitrile (AN) and methyl methacrylate (MMA) on synthesis expansion performance thermally expandable microspheres (TEMs). TEMs with ratios, specifically AN to MMA ratios 100:0, 90:10, 80:20, 70:30, were synthesized via free radical suspension polymerization. The inner morphology, crystallinity, blowing agent encapsulation efficiency, ratio analyzed using scanning electron microscopy (SEM), Fourier-transform infrared...
In this work, pre-oxidized polyacrylonitrile fibers are treated with ultrasonic etching and solution to produce ultra-thin sections. The evolution of the fibers’ microstructure in pre-oxidation process is observed, transformation model proposed. Scanning electron microscopy high-resolution transmission were used observe changes fibers. Fourier transform infrared spectroscopy X-ray diffraction chemical structure crystallization degree process. results revealed that exhibited a smooth surface,...
Amorphous BC2N powders were prepared by mechanical milling with hexagonal boron nitride and graphite as starting materials. A bulk amorphous compound was produced sintering the as-milled in a vacuum of 10−5 Torr at temperature 1470 K. The conductivity measurement for showed that it behaves semiconductor band gap energy 0.11 eV temperatures ranging from room to 560 K semimetal between 740 mechanism formation is discussed.
