ZnO nanowire arrays were synthesised for dye-sensitised solar cell applications using the chemical bath deposition technique. To study the effect of the particle size in the seed layer on the growth and resultant photoconversion efficiency, we prepared various seeded FTO substrates by repeating the seed layer sol-gel…
Semiconductor nanocrystals, especially their ordered assemblies, are promising materials for various applications. In this paper, we investigate the photoconductive behavior of sub-micron size, ordered three-dimensional (3D) assemblies of octapod-shaped CdSe/CdS nanocrystals that are contacted by overlay electron-beam…
Lead-free and multiferroic 0.7BiFeO3–0.3BaTiO3 ceramics doped with K (0.5, 1.0, 3.0 and 5.0 mol%) have been successfully prepared by a solid state mechanical milling technique. The single phase perovskite was found at calcination temperature of 900°C for 6 h. The effects of K doping on the crystal structure, microstru…

Spectral dependence of photostructural transformations on the surface and in the interior of thermally evaporated As2S3 thin films is studied under the influence of bandgap, sub-bandgap and super-bandgap light. For the given light intensity (W~15 mW/cm2) the irradiation by bandgap and super-bandgap light leads to part…
We present ballistic and fragmentation data for brittle, granular aluminum spheres following high- velocity impact (0.5-2.0 km/s) on thin steel plates. These spheres, formed from isostatically pressed alu- minum powder, are representative of a wide variety of metallic reactive materials currently being studied. Simple…
Sputter-deposited titanium substrates were anodically treated in sulfuric acid solution both in potentiostatic and potential-sweep modes. The morphology, crystallization, chemical compositions and electrochemical properties of anodic titanium oxide films were detected by AFM, SE, Raman spectra, XPS and EIS. The formed…
Minimizing the formation of inorganic scale deposits in industrial water continues to be a challenge for water treatment systems. In order to meet this challenge a novel biodegradable poly (DL-malic acid-co-citric acid) copolymer, effective in providing calcium carbonate scale inhibition was developed. Synthesis and c…
About the separation methods of the traditional Chinese medicine components, there are common difficulties like time-consuming and compositions exist cross. Highly efficient way of separation is urgently needed in chinese medicines. The experiment adopted a better and specific 2-hydroxy-3-carboxy-N,N,N-trimethyl-propy…
The synthesis of a terpyridine-guanosine ligand and its reaction with copper(II) to yield a new [2 + 2] metallo-rectangle is reported. The metallo-rectangle was characterized by single crystal X-ray diffraction and the structure showed significant intramolecular π-π stacking interactions between the two terpyridine mo…
The effect of intrinsic point defect on the magnetic properties of ZnO nanowire is investigated by the first-principles calculation based on the density functional theory (DFT). The calculated results reveal that the pure ZnO nanowire without intrinsic point defect is nonmagnetic and ZnO nanowire with V(O), Zn(i), O(i…
Since selective oxidation of alloying elements on the surface of steel products influences their surface properties, characterization of the surface oxides which can be considered as non-metallic inclusions is of great importance. In this study, X-ray photoelectron spectroscopy (XPS), X-ray diffractometry (XRD) and X-…
One-dimensional nanostructures of BaO-xTiO2 binary oxides with a high oxygen deficiency and a good dielectric performance are of great interest but seldom studied. In the present study, single-crystalline BaTi4O9 (stoichiometric BaO–4TiO2) nanowires were synthesized using a simple, one-step molten-salt method by co-he…
The purpose of this research is the development of a hybrid volatile organic compounds (VOCs) treatment process, which consists of adsorptive separation and catalytic oxidation. This process greatly reduces energy consumption compared with conventional thermal or catalytic combustion processes. Low concentrations of V…

Bulk and nano Zinc ferrite (ZnFe2O4) were prepared by solid state reaction and co-precipitation methods respectively. Mean size of the bulk and nano Zinc ferrite particles have been deduced to be around 49 and 8 nm respectively based on XRD measurements. Although the Mossbauer spectra corresponding to both the nano an…
The present investigation is a detailed study aiming to understand the origin of the ferromagnetism of the well-characterized Nd-doped ZnO films. Raman scattering shows that the E2 high phonon line of Zn1-x Nd x O (x = 0, 0.05, 0.10, and 0.15) is broadened asymmetrically and shifts to a lower frequency, suggesting mic…
Growth and structure of picene thin films on SiO2 surface were studied from ultrathin film to thick film regimes (nominal film thickness upto 100 nm) by using X-ray diffraction and atomic force microscopy. We found that from initial film growth picene form crystalline grains with a certain multilayer height, in which…
Current treatments for human coronary artery disease necessitate the development of the next generations of vascular bioimplants. Recent reports provide evidence that controlling cell orientation and morphology through topographical patterning might be beneficial for bioimplants and tissue engineering scaffolds. Howev…
We study the effect of donor-acceptor orientation on solvent-dependent three-photon transition probabilities (δ(3PA)) of representative through-space charge-transfer (TSCT) systems, namely, doubly positively charged [2,2]-paracyclophane derivatives. Our cubic response calculations reveal that the value of δ(3PA) may b…
