Abstract Improving the performance of anode is a crucial step for increasing power output marine sediment microbial fuel cells (SMFCs). A multi‐walled carbon nanotube/polyaniline (MWCNTs/PANI) modified was prepared by way electrochemical deposition and its investigated in this paper. Result shows that wettability felt becomes better number bacteria (9.52 × 10 12 m −2 ) on biofilm increased respectively, which 9 times higher than unmodified. The anti‐polarization ability increases...
Surface nitridation is used to eliminate O-polar inversion domains and control the growth of single-domain Zn-polar ZnO film on sapphire (0001) substrate by rf-plasma-assisted molecular-beam epitaxy. It found that temperature crucial for achieving quality AlN buffer layers films with cation polarity, as demonstrated ex situ transmission electron microscopy. Under optimal conditions, a 4×4 surface reconstruction was observed, which confirmed be characteristic structure films, can fingerprint...
Magnetization is produced in samples of O-polar ZnO after implantation krypton ions.
Surface modification of Cu current collectors (CCs) is proven to be an effective method for protecting lithium metal anodes. However, few studies have focused on the quality and efficiency layers. Herein, a novel home-made filtered cathode vacuum arc (FCVA) co-deposition system with high efficiency, good repeatability environmental friendliness proposed realize wide range regulation film composition, structure performance. Through this system, ZnMgTiAl quaternary alloy films, which affinity...
Elastic properties and tensile strength of single-walled carbon nanotubes, which have topological coordinated defects, under hydrostatic pressure been studied by using molecular-dynamics simulations ab initio electronic structure calculations. The Young's moduli in both the axial direction radial are determined different levels pressure. It is found that stiffness nanotubes changes with strain a graded manner. When larger than 0.10, tubes become softened. at failure lowered existence defects.
Different configurations of a single nitrogen atom adsorbed at different sites on the sidewall single-walled carbon nanotubes (SWNT's) are studied through first-principles calculations. It is found that outer surface tube wall reactive to atom, and can be chemically it forming an exohedral complex with binding energy $\ensuremath{\sim}3.86\mathrm{eV}$ for (5,5) SWNT. Although inner less than surface, still endohedral order $\ensuremath{\sim}1.78\mathrm{eV}.$ The local structure SWNT around...
Well-defined cubic AlN ultrathin layers formed by nitridation of Al2O3 (0001) substrate at various temperatures were observed high-resolution transmission electron microscopy. The polarity the strongly depends on pretreatment and temperature. structure plays a key role in selection subsequent ZnO films, both Zn-polar O-polar films could be steadily obtained control layers.
The polymers that served for solar cell arrays are constantly subject to various hazards, such as atomic oxygen (AO), ion irradiation, or electrostatic discharge (ESD) events. To address these issues, we fabricated and sifted CrO0.16/CuNi-coated Kapton with a gradient structure the goal of reaching an equilibrium between AO durability resistance. resulting material exhibits impressively low Ey 6.61 × 10-26 cm3 atom-1, 2.20% which was detected pristine Kapton. Self-evolution CrO0.16 coating...
Oxygen radicals pregrowth treatment and surface nitridation were used to eliminate Zn-polar inversion domains control the growth of single-domain O-polar ZnO film on sapphire (0001) substrate by rf plasma-assisted molecular beam epitaxy. We found that formation oxygen-terminated prior is crucial for achieving anion polarity in subsequent AlN layers, as demonstrated 3×3 reconstruction during ex situ determination. This method, general, can be applied other polar films, such II-VI oxides III-V...
The investigation of cyclic shear response on a geosynthetic–soil interface is important for reinforced soil structures. A stereoscopic geogrid with thickened transverse-rib thickness increases the interaction compared planar geogrid. In this study, three-dimensional printing technology was used to produce geogrids thicknesses 5, 10, 15 and 20 mm. influences different displacement amplitudes (1, 3, 6 10 mm) normal stresses (20, 40 60 kPa) direct tests under static loading at geogrid–sand...
The rotation domain structures in ZnO films grown on sapphire substrates under different pre-treatment conditions have been investigated by situ reflection high-energy electron diffraction and ex x-ray (XRD). It was found that appropriate nitridation treatment, forming a thin AlN film the substrate, domains could be completely suppressed, full width at half maximum of only 180 arcsec observed (0 0 2) XRD rocking curves. mechanisms for elimination are discussed.
Molecular-dynamics simulations were used to investigate the storage capacity of hydrogen in single-walled carbon nanotubes (SWNT's) and strain nanotube under interactions between stored molecules SWNT. The capacities inside SWNT's increase with tube diameters. For a SWNT diameter less than 20 \AA{}, depends strongly on helicity maximal radial is range 11%--18%, armchair that zigzag SWNT's. tensile strengths decrease increasing diameters, approach graphite (20 GPa) for larger-diameter tubes.
The optical emission spectra of the plasma generated by a 1.06-μm Nd:YAG laser irradiation Al target in air was recorded and analyzed spatially resolved manner. Electron temperatures densities were obtained using relative intensities Stark-broadened linewidths Al(I) lines, respectively. dependence electron density temperature on distance from surface irradiance manifested. We also discussed how takes part evolution process confirmed that ignition collisions between energetic electrons...
