Herein we report the deformation of PDMS-based particles at a liquid-liquid interface at varying degrees of softness. Direct visualization of the particle adsorption to the interface reveals at least five different modes of deformation from the complete spreading of a polymer resin droplet to a non-deforming, rigid pa…
We have prepared 1:1 blend of PMMA /PVAc in chloroform as the common solvent, the blend is doped with the light emitting polymer Poly [2-methoxy-5-(3’,7’-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) at a very low concentrations of 0.1%, 0.2%,0.3%, 0.4% and the films are prepared by solution cast method. Samples…
The effect of spin—orbit coupling on the electron levels of (5, 3), (8, 7), (11, 3), (18, 11), (10, 5), (8, 8), and (13, 0) gold nanotubes of various diameters and chirality was studied in the framework of the relativistic version of the linear augmented cylindrical wave method. Spin-dependent band structures and elec…
Abstract The results of X-ray diffraction, electron microscopy, extended X-ray absorption fine structure (EXAFS) spectroscopy, and X-ray photoelectron spectroscopy studies of nanostructured ZnS : Cu(Mn) coatings obtained by ultrahigh vacuum thermal deposition onto the surface of anodic Al2O3 porous matrices are presen…
The spinel and interacting Cu( <sc>ii</sc> ) species have no activity for N <sub>2</sub> O decomposition, while free Cu( <sc>ii</sc> ) shows activity.
Kinetically constrained models (KCMs) are interacting particle systems on $\mathbb{Z} ^{d}$ with a continuous-time constrained Glauber dynamics, which were introduced by physicists to model the liquid-glass transition. One of the most well-known KCMs is the one-dimensional East model. Its generalization to higher dime…
Hybrid oxidation catalysts and adsorbent materials containing niobium( <sc>v</sc> )–copper( <sc>ii</sc> ) for the decontamination of real wastewater containing organic pollutants are reported herein.
Abstract—A numerical study of mechanical properties of zirconium ceramic–cortical bone tissue biocomposite has been fulfilled using a multiple-scale approach. Evolution of mesoscopic stress distribution in the components of biocomposite during its deformation has been studied with the assumption of damage accumulation…
Supported polymetallic catalysts (5–15% wt% of active phase) for deep oxidation and hydrogenation were successfully prepared by Self-propagating Surface Synthesis (SSS) using metal nitrates as oxidants and urea as a fuel. Commercial granules of γ-Al 2 O 3 ; NaA, NaX, ZSM-5 zeolites; and silica gel were used as support…
The preparation of m Al 2 O 3 – n YSZ-6 and m Al 2 O 3 – n YSZ-5 nanocomposite powders ( m + n =100 wt%, m = 0–60 wt%) by Impregnation Combustion Synthesis (ICS) with urea as a fuel was studied. Maximal combustion temperatures were measured and calculated for different modes of YSZ introduction. In ICS-produced powder…
Some properties of the functions yielding from the temperature field have been employed as a tool to determine the structural zones’ localization in a large static steel ingot. Thus, a numerical simulation was performed to generate the temperature field converged subsequently into the thermal gradient field. As a resu…
An investigation of structural and optical properties of Ni doped ZnO nanoparticles, prepared by modified sol-gel process at different annealing temperature. X-ray diffraction study reveals that there is no secondary phase formation and confirmed about its space group P63mc. Rietveld refinement of X-ray data shows dec…

Rheological behavior of chitosan succinimide in water-glycerol mixed solvent was studied. Partial replacement of water by glycerol leads to an increase in the complex viscosity of the polymer in solution, to the formation of the network of intermolecular linkages and transition of the system to the gel state at a lowe…
Polycrystalline TiSe2 and its Iron intercalated samples have been successfully grown by solid state synthesis method. The electrical transport property of pure sample is semiconducting in the entire temperature range with a clear anomaly depicting the onset of charge density wave (CDW) at 200K. Temperature that corres…
New goals for providing better solutions with the help of nanotechnology have emerged from the electronics industry. Nano-electronics has focused on the structural, optical, magnetic, and photoluminescence properties of nanomaterials for developing optoelectronic devices. These properties play a vital role at the nano…
Superhydrophobic surfaces are practically important for several real-life applications such as self-cleaning, anti-corrosion and drag reducing surfaces, non-wetting cloths, oil–water separation, water-repellent surfaces and microfluidic devices, <italic>etc.</italic>
Electrochemical dimerization of N,N′ -diphenylbenzidine ( DFB ) has been studied in a water/DMF (20/80, v/v) mixture by cyclic voltammetry and controlled potential techniques.

Nanomaterials consist of larger fraction of surface atoms and the fraction of surface atoms increases with the decrease in size. Increase in surface atoms and high surface area provides exceptional properties to nanomaterials. In internal combustion engine the nanoparticles are used as fuel or lubricant additives and…
We have prepared a highly luminescent quantum dot (QDs)-TiO2 nanocomplex film by the dip coating method. Because QDs with 3-mercaptopropionic acid as a ligand adsorb ionized Ti+ cations on the TiO2 particle, the average distance between the QDs can be changed through controlling the porosity in the film. The porosity…
