Gold nanoparticles on a heavily-doped Si substrate were synthesized through direct electroreduction of bulk AuCl 4 ions. The optical properties of the nanoparticles were determined from ellipsometric analysis. The Lorentz-Drude model was used to represent the effective dielectric function of the gold nanoparticles. A…

Abstract Ge nanocrystals were fabricated in Si3N4 matrix by rf (radio frequency) magnetron sputtering, followed by post-annealing in a conventional tube furnace filled with N2. Ge content was varied between 30-50vol% in Ge-rich silicon nitride (GRN) layer with variation of annealing temperature between 600-900 °C were…
Titanium dioxide particles behave as capillary traps for polystyrene particles when an external DC electric field is directed orthogonal to a planar water/oil interface.
Here we highlight the recent advances in synthesizing some novel nanostructures where polar surfaces and the associated electrostatic interactions appear to play critical roles. Some examples, including ZnO nanospring and nanoring, AlN nanonecklace, and CrSi2 nanoweb, are discussed.
ZrO2 thin films deposited on silicon wafer and glass substrate by dc magnetron sputtering with different deposition time. Film thickness and refractive index of ZrO2 films have been studied by using spectroscopic ellipsometry (SE) and spectrophotometric method (SM). The film thicknesses of both methods were compared w…
Hexagonal YbFeO3 (h-YbFeO3) were prepared by solvothermal and Pechini methods. Although the morphology of h-YbFeO3 synthesized by solvothermal method was hexagonal plate, h-YbFeO3 synthesized by the Pechini method was composed of large aggregates of irregularly-shaped fine particles. Activities of Ru catalysts support…
CdMoO 4 nano-octahedra were grown in situ at room temperature by reverse-microemulsion. Energy evolution from this growth process was monitored using microcalorimetry. The microcalorimetric heat flow (MCHF) curve showed a characteristic endothermic peak for the initial reaction, and double discontinuous exothermic pea…
As CMOS devices continue to shrink, the formation of ultra shallow junction (USJ) in the source/drain extension remains to be a key challenge requiring high dopant activation, shallow dopant profile and abrupt junctions. The next generations of sub nano‐CMOS devices impose a new set of challenges such as elimination o…
The current work is part of the EPSRC MUZIC project, which established the collaboration among several universities to carry out a multidiscipline study on the breakaway oxidation of zirconium alloys. The overall goal of the project is to further understand the mechanisms of the oxidation and breakaway process of zirc…
The present study is aimed at the overall improvement in the efficacy, reduced toxicity and enhancement of therapeutic index of cisplatin. Nanocapsules of cisplatin containing ethylcellulose have been prepared using solvent evaporation technique under ambient conditions. The prepared nanocapsules were used for control…
Grain boundary model in phase-field simulation during microstructure evolution in solid states is discussed based on the way to express grain boundary and its physical background. The effects of different values of simulation parameters on feature of grain boundary in the phase field model are investigated systematica…
ABSTRACT To build up the conservativeness of aged paper herita ges, the strength reinforcement treatment using var-ious cellulose derivative solutions was considered. Hand-made Hanji prepared by traditional paper-making technique was firstly simulated in order to modify the overall of paper properties like aged paper…

In this paper, we investigate the doping effect on conductivity of poly(3,4-ethylene dioxythiophene):poly (styrenesulphonic acid)(PEDOT ∶PSS)and its influence on performance of polymer solar cell. The experiment demonstrates that the conductivity of PEDOT ∶PSS is improved obviously by doping polar solvent dimethyl sul…
Spin-coating of colloids is a versatile method in fabricating films of colloidal particles at a short span of time. Controlling key parameters like the rate of rotation, the initial concentration and the nature of the continuum phase is easy to perform experimentally. However, the effects of these parameters are not f…

Stress corrosion cracking (SCC) of Mg alloys is intergranular (IGSCC) or transgranular (TGSCC). A continuous or nearly continuous second phase, typically along grain boundaries, causes IGSCC by micro-galvanic corrosion of the adjacent Mg matrix. IGSCC is expected in all such alloys, typical of most creep resistant all…
The oxidative chemical polymerizations of para aminophenol was synthesized in acidic medium using potassium dichromate as an oxidant at 00C and its nano compound was synthesized using an anionic surfactant Sodium Dodecyl Sulphate. They were characterized by FT- IR, UV-VIS, 1H-NMR, TGA, SEM and TEM. The formation of be…
