Nb-doped TiO2-based nanostructures were novelly prepared by an economical and environmentally friendly hydrothermal method from TiO2 and Nb2O5 powder precursors. The proposed formation mechanism is acceptable for the design of various Nb-doped TiO2-based nanostructures. Furthermore, Nb-doped TiO2 nanostructured bulk m…
The 2,2-bis(hydroxymethyl)propionic acid (BHP)-based generation 1 dendron with two palmitate tails (D1-C16) and the generation 2 dendron with four palmitate tails (D2-C16) were synthesized. The coupling of D1-C16 or D2-C16 with hyperbranched polyethylenimine (PEI) through the amidation reaction resulted in amphiphilic…
Four molecular Pt-carbonyl clusters decorated by Cd-Br fragments, i.e., [Pt(13)(CO)(12){Cd(5)(μ-Br)(5)Br(2)(dmf)(3)}(2)](2-) (1), [Pt(19)(CO)(17){Cd(5)(μ-Br)(5)Br(3)(Me(2)CO)(2)}{Cd(5)(μ-Br)(5)Br(Me(2)CO)(4)}](2-) (2), [H(2)Pt(26)(CO)(20)(CdBr)(12)](8-) (3) and [H(4)Pt(26)(CO)(20)(CdBr)(12)(PtBr)(x)](6-) (4) (x = 0-2)…
The electrochemical conversion of NOx on non-impregnated and BaO-impregnated LSM15-CGO10 (La0.85Sr0.15MnO3–Ce0.9Gd0.1O1.95) porous cell stacks has been investigated, and extensive impedance analysis have been performed to identify the effect of the BaO on the electrode processes. The investigation was conducted in the…
Aqueous dispersions containing TiO2 nanoparticles and hydrophilic poly(2-ethyl-2-oxazoline) allow the preparation of highly transparent nanocomposites containing up to 44 wt% of TiO2. Transmission Electron Microscopy (TEM) images indicate that the nanoparticles are homogeneously distributed in the polymeric matrix wit…
The stability of double emulsions is crucial for their application as delivery systems and microcapsule templates. However, this stability is often challenged by many molecular species present in customized formulations and by the fast dynamics when microfluidic emulsification processes are used. With the help of desi…
One-dimensional ferromagnetic iron dendritic wire array film is prepared by facile electrodeposition. The space hindrance effect caused by neighbouring crystals resists the free growth directions parallel to the substrate, which is considered as a possible growth mechanism of one-dimensional morphology. Dendritic iron…
Round-robin tests were conducted for designing standard procedures for thermal desorption analysis (TDA) of hydrogen. Scatters of diffusive and non-diffusive hydrogen contents measured at various institutions using common materials and experimental procedures were examined. Some factors causing the scatter and their r…
Fluorinated polyhedral oligomeric silsesquioxane (F-POSS) compounds were prepared by employing a facile, corner-capping methodology. Using this modular approach, fluorocarbons with varying degree of fluorine content and architecture were installed on the POSS cage of a partially condensed trisilanol. The melting prope…
Sr 2 TiO 4 :Eu 3+ phosphors using M + (M = Li + , Na + , and K + ) as charge compensators were prepared by the solid‐state reaction. The powders were investigated by powder X‐ray diffraction (XRD) and photoluminescence spectra (PL) to study the phase composition, structure, and luminescent properties. The results show…
The relationships between corrosion inhibition performance of four kinds of Schiff base inhibitors and their molecular electronic properties have been studied by quantum chemistry method at the level of DFT/B3LYP with the 6-31+G (d, p) base sets. The relationships between the corrosion inhibitor efficiency (IE) and th…
Highly crystallized graphite films were prepared from carbonized films derived from commercially available aromatic polyimide films by simple heat treatment at temperatures exceeding 3000 °C. Thermal conductivity κ along the longitudinal direction of each graphite film was measured at room temperature in air by a stea…
Recent developments of nanosize materials of metal and metal oxide particles are intensively pursued because of their prominence in different fields of applications. Among all the transition metal oxides, CuO is a potential candidate for the application of magnetic storage devices, solar energy transfer, sensors, and…
Using biological medium, such as plant extract for the biosynthesis of nanoparticles is an ecofriendly and emerging scientific trend. On this back drop the present study focused on the biosynthesis of silver nanoparticles using Cissus quadrangularis and evaluation of its antimicrobial and anticancer potentials. The bi…
Cu 2 S and CdS nanoparticles due to their unique band character, high extinction coefficients and impact ionization effects are the most promising light absorbers for solar cells. Here Cu 2 S and CdS nanoparticles are prepared by wet chemical method and are characterized using UV-Vis Absorption Spectroscopy and X-ray…
Single-walled carbon nanotubes (SWCNTs) are newly discovered material of crystalline carbon that forms single-carbon layer cylinders with nanometer diameters and varying lengths. Although SWCNTs are potentially suitable for a range of novel applications, their extremely small size, fiber-like shape, large surface area…

Undoped ZnO thin films are prepared by polymer‐assisted deposition (PAD) and treated by postannealing at different temperatures in oxygen or forming gases (95% Ar + 5% H 2 ). All the samples exhibit ferromagnetism at room temperature (RT). SQUID and positron annihilation measurements show that post‐annealing treatment…
