The encapsulation of noble-metal nanoparticles (NPs) in metal-organic frameworks (MOFs) with carboxylic acid ligands, the most extensive branch MOF family, gives NP/MOF composites that exhibit excellent shape-selective catalytic performance olefin hydrogenation, aqueous reaction reduction 4-nitrophenol, and faster molecular diffusion CO oxidation. strategy using functionalized cavities MOFs as hosts for different metal NPs looks promising development high-performance heterogeneous catalysts....
Highly efficient solar cells (conversion efficiency 11.9%, fill factor 70%) based on the vertically aligned single-crystalline nanostructures are fabricated without any pre-fabricated p-n junctions in a very simple, single-step process of Si nanoarray formation by etching p-type Si(100) wafers low-temperature environment-friendly plasmas argon and hydrogen mixtures. Detailed facts importance to specialist readers published as ”Supporting Information”. Such documents peer-reviewed, but not...
An overview is presented of plasma-etching processes used in the fabrication ULSI (ultralarge-scale integrated) semiconductor circuits, with emphasis on work our facilities. Such circuits contain structures having minimum pattern widths 0.25 µm and less. Challenges plasma etching evolving to such dimensions have come from implementation antireflective coatings thinner, more etch-sensitive photoresists; increased aspect ratios needed meet design requirements; additional hard-mask steps at...
This work reports upon the dilution effect of Ar + H2 on microstructures, optical, and photovoltaic properties hydrogenated nanocrystalline silicon (nc-Si:H) thin films. High crystallinity (up to 82.6%) nc-Si:H films were fabricated from silane diluted by in a low-frequency inductively coupled plasma (LFICP) facility at low temperature 300 °C. The substitution diluent gas leads an increase deposition rate, grain size, crystallinity, decrease optical bandgap. Varying content caused...
The treatment of an Ar + H 2 plasma generated by a low-frequency inductively coupled system at 500 °C introduces n-type region (of average electron concentration ∼10 15 cm −3 ) on Czochralski p-type substrate, forming deep p–n junction. Examination microscope shows that the produces uniform nanocones surface and some defects, such as dislocations platelets, in subsurface. All these observed results are hydrogen-related. conductivity type conversion is due to formation hydrogen-enhanced...
Nanosecond-pulsed laser ablation is often accompanied by adverse thermal effects such as oxidation, debris recast and burr formation. To reduce these effects, in this paper, the authors present underwater milling process using RSA-905 fine-grained aluminium target material for first time. The results show that channels up to 200 μm width, 700 depth bottom roughness around 1 µm Ra could be fabricated with reduced effects. By conducting multi- single-factor experiments, empirical models...
A completely new type of nitrogen-doped polymer nanospheres and the derived porous carbon were produced by taking 2,4-diamino-6-hydroxypyrimidine as precursor. When functioning electrode materials, they demonstrated...
p-type nanocrystalline silicon thin films with a series of thicknesses were deposited on both glass and n-type (100) wafer substrates through low-frequency inductively coupled plasma. No H2 dilution was employed in the growth process. The structural electric properties investigated by XRD, Raman spectra, Hall effect measurement system. XRD patterns show an obvious enhancement peak intensity increasing thickness. crystalline volume fraction ranges from 83% to 87%, depending film carrier...
Abstract To incorporate divalent transition metals into molecular sieve frameworks remains a great challenge in zeolite chemistry. In this study, Zn was successfully incorporated inside the MWW framework, namely Zn‐MWW (Zn−Si), through hydrothermal synthesis. A combined DFT and X‐ray absorption near edge structure (XANES) simulation applied to unravel location of structure, indicating that most plausible position is T5 with two sodium cations close neighboring oxygen neutralize charge...
Corrosion protection coatings need frequent developments to cater different challenges arising from users. In addition a long lasting corrosion protection, aesthetic requirements and multi-functional properties by the same coating system are prominent demands be considered. Productivity is another vital factor considered, as there thriving demand users have more productive systems, such smaller number of layers in system. Thus, attention using technologies an essential step fulfil these...
A phenomenological model is presented to determine the experimental value of spontaneous polarization GaN. The expression at room temperature obtained. electrostrictive coefficient M33 a wurtzite GaN film used evaluate exact can be obtained as long single crystal zinc blende measured. also values in other III-V nitrides, AlN and InN.
The scanning vibrating electrode technique (SVET), electrochemical impedance spectroscopy, and salt spray testing are used to investigate the ability of Zn rich sol-gel coatings provide sacrificial protection carbon steel. Three types (containing either powder, a colored pigment, or both) applied Intact shown act as barrier layers through which electrolyte ingresses over time. Under conditions where substrate is exposed by an artificial coating defect, SVET extent different offer when defect...
Many ways can be used to tune in-plane strains and thus tailor the physical properties of ferroelectric films. Impact effective shear strain on equilibrium phases polarization states single-domain PbTiO3 thin film is investigated by a thermodynamic theory. The modeling results indicate that not only but also orientations components produce profound impacts film, which essentially different from cases S6=0. Different controlled temperature, strains, especially strain.
