Objective To develop paclitaxel-loaded polymeric micelles from poly (e-caprolactone)-poly (ethylene glycol)-poly(e-caprolactone) (PCL-PEG-PCL),and to evaluate in vitro cytotoxicity as well as in vivo antitumor activity against EMT-6 tumor breast cell.Methods Paclitaxel-loaded polymeric micelles were prepared by thin-f…
Abstract The photovoltaic performances of dye-sensitized solar cells employing solid polymer electrolytes have been greatly improved by the introduction of a chemically doped (p-type) conjugated polymer junction layer onto a conventional platinum-layered counter electrode. The increased energy conversion efficiency wo…
Joule heat is generated by applying an electric filed to a conductive layer located beneath or above the amorphous silicon film, and is used to raise the temperature of the silicon film to crystallization temperature. An electric field was applied to an indium tin oxide (ITO) conductive layer to induce Joule heating i…
Low band gap organic semiconducting polymers were prepared as p-type donors for organic photovoltaic devices. A novel dibrominated monomer composed of phenothiazine, thiophene, and benzothiadiazole (DPDTBT) was synthesized as a low band gap core block. DPDTBT was copolymerized with three different boronic esters of di…
ZnO-PEG-ZnO complex film was fabricated by forming ZnO thin film on the Polyethyleneglycol (PEG) thin film. ZnO thin films were formed by an electrostatic method and ZnO-PEG complex films were fabricated by adsorbing PEG on the ZnO thin films surface with hydrogen bond. The electrochemical characteristic of the ZnO-PE…
Reaction of a bis-tetrazinyl pyridine pincer ligand, btzp, with a vanadium(III) reagent gives not a simple adduct but dichlorido{3-methyl-6-[6-(6-methyl-1,2,4,5-tetrazin-3-yl-κN(2))pyridin-2-yl-κN]-1,4-dihydro-1,2,4,5-tetrazin-1-yl-κN(1)}oxidovanadium(IV) acetonitrile 2.5-solvate, [V(C11H10N9)Cl2O]·2.5CH3CN, a species…
IrO2 nanodot (ND) growth by plasma enhanced atomic layer deposition as a charge storage layer has been investigated. As-deposited IrO2 NDs showed a high density of 2.38 x 10(12)/cm2 and a small mean diameter of 3.22 nm, and turned into a spherical shape with a large dot-to-dot separation after annealing. The metal-oxi…
Normal 0 false false false EN-US X-NONE X-NONE Abstract The transformation of ( R )-(+)-citronellal to isopulegols and menthols in a one-pot reaction was improved using a zeolite catalyst. The one-pot transformation of ( R )-(+)-citronellal was studied through a Ni/ZnBr 2 /β-zeolite catalyst. The Ni/ZnBr 2 /β-zeolite…
From first-principles calculations we show that there is an intimate relationship between the Se height and the spin configuration of the underlying Fe square in ${M}_{x}$Fe${}_{2\ensuremath{-}y}$Se${}_{2}$, where $M$ denotes an alkali metal. A displacement of the Se atom by an amount as small as 0.2 \AA{} is enough t…
V2O5-coated ZnO 1D nanostructures were prepared by using a two step process: thermal evaporation of a mixture of ZnO and graphite powders (ZnO:C = 1:1) in an oxidative atmosphere and sputter-deposition of V2O5. Scanning electron microscopy revealed that the nanostructures had a rod-like morphology with the thickness d…
We report the synthesis of high quality single crystalline ZnO nanowall networks (NNs) using ammonia solution etching of a ZnO nanowire-nanowall heterojunction (NNH) structure. Synchrotron X-ray diffraction revealed that the full-width-at-half-maximum of the ZnO (0002) peak in the ZnO NN sample was much narrower than…
Compared with other materials, zinc oxide (ZnO) exhibits stability in air, high-electron mobility, transparency and low light sensitivity. We investigated these properties in ZnO thin-film transistors (TFTs) containing a cross-linked poly(vinyl alcohol) (C-PVA) (1:3) buffer layer stacked between the semiconductor and…
Co(II), Ni(II) and Cu(II) complexes have been synthesized with asymmetric aldazines (LI and LII) derived from benzophenone hydrazone and substituted salicylaldehyde. The structure of the complexes has been proposed in the light of elemental analyses, IR, UV-Vis., and magnetic studies. These complexes are soluble in DM…
Most of the existing anticancer drugs are very potent small molecules; their efficacy is constrained by their systemic toxicity, narrow therapeutic window, low drug loading, size control, scale up, cost of formulation but also as a result of drug resistance and limited cellular entry. MWCNTs (Multiwalled Carbon Nanotu…

In this work a detailed study made about the types of operations and understanding the mechanisms of the resistance changing in the device. SnO2 thin fi…
This paper describes our studies on development of methods for preparing colloid solutions of core-shell particles composed of core of materials with imaging ability and shell of silica that is inert to living bodies, and on their imaging properties. The methods for silica-coating are based on hydrolysis and condensat…
Bonding technology and bonding mechanism of metal to ceramic including brazing, diffusion bonding, friction welding and etc were reviewed in this study. Various factors should be considered from a bonding design step to acquire a good bonding joint because of a large difference between metal and ceramic in crystal lat…
Nanoindentater tests were conducted to conducted nanoindentation microhardness of the individual phase of ferrite and martensite of 680MPa dual-phase (DP) steel charged with hydrogen. Hydrogen was charged by electrochemical method with current densities of 150, $200mA/cm^2$ for charging times of 5, 10, 25, 50 hours, r…

We demonstrate improved short-wavelength internal quantum efficiency (IQE) of a-Si/c-Si heterojunction (HJ) solar cells with a surface nanopillar (NP) array via simulation. The gain in IQE is attributed to the light-field modulation caused by the cavity resonance inside the NPs, in which the light energy is effectivel…
