Metastable phase VO2 (B) nanorings were synthesized by hydrothermal treatment of inorganic V2O5 sol. It was found that oriented attachment growth and a subsequent rolling mechanism are essential for the formation of VO2 (B) nanorings under hydrothermal conditions.
Tafel polarization method was used to assess the corrosion inhibitive and adsorption behaviours of amino-tris(methylenephosphonic) acid (ATMP) for C38 carbon steel in 1 M HCl solution in the temperature range from 30 to . It was shown that the corrosion inhibition efficiency was found to increase with increase in ATMP…
The solubility of sulfanilamide (SA) in propylene glycol + water cosolvent mixtures was determined at temperatures from 293.15 to 313.15 K. The thermodynamic functions: Gibbs energy, enthalpy, and entropy of solution and mixing were obtained from these solubility data by using the van’t Hoff and Gibbs equations. The s…
Motivated by experimentally-observed biocompatibility enhancement of nanoengineered cubic zirconia (ZrO(2)) coatings to mesenchymal stromal cells, we have carried out computational analysis of the initial immobilization of one known structural fragment of the adhesive protein (fibronectin) on the corresponding surface…
In the present article we describe a facile biosynthetic method for the silver nanoparticles highlighting myconanotechnology and its antimicrobial efficacy. The nanoparticles were characterized using UV-vis spectroscopy, dynamic light scattering (DLS), transmission electron microscopy (TEM), atomic force microscopy (A…
Alzheimer's disease is a progressive neurodegenerative disorder that is characterized by the deposition of beta-amyloid (Abeta) peptide and the formation of neurofibrillary tangles in neurons. The Abeta peptide is a key molecule in the pathogenesis of Alzheimer's disease and an important marker for early diagnosis. Su…
The surface plasmon resonance (SPR) of palladium (Pd) nanocrystals is of potential importance due to their catalytic properties and surface stability. Pd nanocrystals with single-, double-, and triple-cavities were produced using a one-pot aqueous approach, where micelles formed by PVP dictate the cavity formation. Th…
The capacitive behaviors of activated carbon (AC) were investigated in K 4 Fe(CN) 6. It was revealed that the AC electrodes in K 4 Fe(CN) 6 exhibited high capacitance (183, 232 and 272 F·g −1 in a cell voltage window of 0–0.8, 0–1.0 and 0–1.2 V, respectively) due to the contribution of the double layer capacitance fro…
A beaded ZnO nanocluster as a novel stand-alone system has been introduced by interconnecting different numbers of highly stable (ZnO)12 basic units. Geometries, stabilities, electronic properties, and vibrational spectra of the beaded ZnO nanoclusters have been systematically studied by using density functional theor…
The physical properties of the sintered sample of Ga2O3(ZnO)9, a member of the homologous series Ga2O3(ZnO)m and recently found to have new structures, were investigated. The material was found to be a new transparent conducting oxide, and is composed of relatively abundant and inexpensive elements compared to indium.…
With a view to combining the desirable electronic and photochemical properties of hexabenzocoronene (HBC) and the C-C bond forming capabilities of thiophenes, 1-(3-thienyl)-2,3,4,5,6-penta(4-tert-butyl-phenyl)benzene (1) was oxidised using FeCl(3). The resulting products, superaromatic thiophene (2) and its 5,5'-dimer…
Mesoporous-type spherical hollow silica nanoparticles were prepared by using a self-assembled alanine-based amphiphile as a template and then were functionalized with curcumin molecules attached to the internal surface of the nanostructure by covalent bonding. The curcumin-immobilized mesoporous hollow silica nanopart…
A simple and versatile method was proposed for self-assembling magnetic nanoparticles and hydrophobic upconversion nanoparticles on to a mesoporous nanoprobe by the means of an electrostatic interaction and binding scheme. The hybrid nanoprobes showed good magnetic and near-infrared luminescent properties, and could b…
The catalytic effect of tetraphenylporphyrin on the oxygen reduction with ferrocene in 1,2-dichloroethane can be finely tuned by varying the molar ratio of the acid to the catalyst present in the solution. The mechanism involves binding of molecular oxygen to the protonated free porphyrin base, in competition with ion…
We have performed coarse grained molecular dynamics simulations (CGMD) to investigate the interactions of generation 7, 5 and 3 (G7, G5 and G3) charge-neutral polyamidoamine (PAMAM) dendrimers with a DPPC (dipalmitoylphosphatidylcholine) monolayer at the air–water interface (model pulmonary surfactant) during the end-…
Alumina is traditionally considered to be inappropriate as a support for high-performance gold catalysts. Here, a highly active Au/meso-AlO catalyst for liquid-phase alcohol oxidations was synthesized using a home-made mesoporous γ-Al2O3 (meso-AlO) via a cation–anion double hydrolysis (CADH) method.
The atom substitution preference of ternary additions in Ni3M-type GCP (geometrically close-packed) compounds with D0a structure was determined from the direction of single-phase region of the GCP phase on the reported ternary phase diagrams. In Ni3Nb, Co and Cu preferred the substitution for Ni-site, Hf, Ta, Ti, V an…
Hexa-Zn-tungstoarsenate(III) [Zn(Hen)]6[B-α-AsW9O33]2·6H2O (1) consists of two [B-α-AsW9O33]9− subunits incorporating a unique turbine-shaped [Zn(Hen)]618+ cluster, which represents the first hexa-ZnII substituted sandwich-type polyoxometalate.
The complexes [Fe(dm4bt)(3)][FeCl(4)](2) (1) and [Fe(dm4bt)(3)][FeBr(4)](2) (2) were prepared from the reaction of 2,2'-dimethyl-4,4'-bithiazole (dm4bt) with FeCl(3)·6H(2)O and FeBr(3), respectively, in methanol. Both complexes were characterized by IR, UV-Vis and (1)H NMR spectroscopy and their structures were studie…
Thermo-responsive PNIPAAm rich hydrogels with controllable properties have been prepared by introducing small quantities of peptide–PNIPAAm bioconjugates where the peptide self-assembled into a β-sheet rich fibrillar network. This was achieved in a one pot synthesis using a thiol-modified peptide as the chain-transfer…
