Hierarchical porous TiO 2 templated from natural Artemia cyst shells for photocatalysis applications
A novel hierarchical porous TiO 2 is synthesized using a natural Artemia cyst shell as template, showing improved photocatalytic performance.
The role of water co-adsorption on the modification of ZnO nanowires using acetic acid
Density functional theory (DFT) and Car-Parinello molecular dynamic simulations were employed to investigate the interaction of acetic acid with non-polar facets of ultra-thin ZnO nanowires. We consider both a dry and a water environment as well as different molecule coverages for the hydrated system. Our calculations…
Row of Dislocation loops as a Vacancy Source in Ultrahigh-Purity Aluminum Single Crystals with a Low Dislocation Density
The vacancy generation process in ultrahigh-purity aluminum single crystals with a low dislocation density was investigated by synchrotron radiation topography using a white X-ray beam. Some straight lines were observed in the topographs taken after temperature rose to 300℃ from room temperature, and they were confirm…
Cationic quaternization of cellulose with methacryloyloxy ethyl trimethyl ammonium chloride via ATRP method
The synthesis of a cationic cellulose copolymer from cellulose macro-initiator (MCC-BiB) and quaternary compound monomer (METMA) via atom transfer radical polymerization (ATRP) was studied. By using dimethylformamide (DMF), the optimum condition for successful synthesis was at the mole ratio of MCC-BIB:Catalyst:METMA…
Effective hydrodechlorination of 4-chlorophenol catalysed by magnetic palladium/reduced graphene oxide under mild conditions
Magnetic palladium/reduced graphene oxide nanocomposites (Pd/rGO-Fe 3 O 4 ) were prepared by depositing Pd nanoparticles on an rGO-Fe 3 O 4 magnetic support.
Uniaxial pressure induced phase transitions in multiferroic materials BiCoO 3
The crystallographic structure stability, spin state and electronic structure variation in tetragonal multiferroic material BiCoO 3 under uniaxial pressure are investigated by means of first-principles density functional theory calculations.
The Formation of Free Standing NiO Nanostructures on Nickel Foam for Supercapacitors
In this study, free standing NiO nanostructures for supercapacitors were obtained by means of chemically depositing of nickel oxide on Ni foam and then they were annealed at various temperatures. The morphological properties of densely covered Ni foams were studied by scanning electron microscopy. Supercapacitor chara…
Skin-resolved local bond contraction, core electron entrapment, and valence charge polarization of Ag and Cu nanoclusters
Consistency between density functional theory (DFT) calculations and experimental observations confirmed our predictions on the behaviour of local bonds, and the electron binding energy of cuboctahedral and Marks decahedral structures of Ag and Cu nanoclusters. The shorter and stronger bonds between under-coordinated…
Investigations on phosphorous doped hydrogenated amorphous silicon carbide thin films deposited by a filtered cathodic vacuum arc technique for photo detecting applications
This paper reports the growth and properties of phosphorous doped hydrogenated amorphous silicon carbide thin films deposited by a filtered cathodic vacuum arc technique using P doped solid silicon target as a cathode in the presence of acetylene gas.
Enhanced Field Emission of ${\rm TiO}_{2}$ Nanowires With UV Illumination
TiO2nanowires with rutile structures on a SiO2/Si substrate were grown by thermal evaporation. A field-emission property of the low turn-on field was reduced to 3.5 and 2.6 V/μm under UVA in 10 min and UVC in 25 min. The wavelength of UVC was higher than the TiO2band-gap, so the electrons more easily tunneled to the v…
Synthesis and properties of hybrid core–shell poly(alkyltrialkoxysiloxane) latex
We discuss the nucleation mechanism and process of hybrid core–shell poly(alkyltrialkoxysiloxane) latex particles’ formation.
Morphology controlling of calcium carbonate by self-assembled surfactant micelles on PET substrate
In the present work, spherical and hexagonal CaCO 3 were fabricated on different surfactant micelle-modified PET substrates at liquid–liquid interfaces. The results revealed a same nanoparticle-mediate self-organization process in which the surfactants act not only as regulators but also as templates.
Intriguing transmission electron microscopy images observed for perpendicularly oriented cylindrical microdomains of block copolymers
Intriguing images of dislocation structures were observed by the transmission electron microscopy (TEM) technique for hexagonally packed cylindrical microdomains in a block copolymer (polystyrene-block-polyethylenebutylene-block-polystyrene triblock copolymer) film. The polystyrene (PS) cylinders were embedded in the…
Investigation of the crystallization of zeolite A from hydrogels aged under high pressure
Aging of hydrogels under high pressure can result in the formation of zeolites with small particle sizes and narrow particle size distribution.
Zn-phthalocyanine-functionalized nanometal and nanometal–TiO2 hybrids: aggregation behavior and excited-state dynamics
Dithiol-substituted Zn-phthalocyanine derivatives (TAZnPc1, TAZnPc2 and TAZnPc3) were synthesized and functionalized on nanometals (Au and Ag) and nanometal-TiO2 hybrids were harnessed to cover the visible region of the absorption spectrum. Photophysical studies reveal that both H- and J-aggregation were present in th…
Channel Composition Effect on the Bias-Illumination-Stress Stability of Solution-Processed Transparent Oxide Thin-Film Transistors Using Amorphous Aluminum-Indium-Zinc-Oxide Channel Layers
Channel composition effect on the device stabilities of In-Zn-O (IZO) and Al-In-Zn-O (AIZO) thin-film transistors (TFTs) were investigated under negative gate bias illumination stress (NBIS) conditions. The fabricated TFTs with a top-gate bottom-contact structure did not show any marked shifts of threshold voltage (ΔV…
COMPARISON OF TWO-DIMENSIONAL-ONE-DIMENSIONAL COUPLING METHODS FOR TIME-HARMONIC ELASTICITY
The coupling of two-dimensional (2D) and one-dimensional (1D) models in time-harmonic elasticity is considered. The hybrid 2D1D model is justified in the case where some regions in the 2D computational domain behave approximately in a 1D way. This hybrid model, if designed properly, is much more efficient than the sta…
Influence of Semi-Solid Isothermal Heat Treatment on Microstructure and Mechanical Properties of Ductile Cast Iron
In this research, the effect of semi-solid isothermal heat treatment on microstructure, hardness and impact toughness of ductile iron (DI) is studied. Heat-treated air-cooled ductile iron shows spheroid graphite, cementite and fine pearlite matrix structure. At the early stages of heating time (up to 20 min), the DIs…
A strong linear correlation between the surface charge density on Ag nanoparticles and the amount of propylene adsorbed
The partial positive charge density of the surface of Ag nanoparticles was modulated by an electron acceptor, 7,7,8,8-tetracyanoquinodimethane (TCNQ), to improve their reversible interactions with olefins such as propylene, but not with paraffin. The silver binding energy in Ag NPs, representing the surface charge den…
