Oxidation of cyclooctene was studied in presence aqueous hydrogen peroxide (30%, v/v) over nano iron oxide. The catalyst prepared by microemulsion method and characterized using various techniques including XRD, TEM and BET techniques for evaluating phase, structure and morphology and surface area. In this study, we investigated the effects of varying the catalyst content, reaction temperature,...

maybe viscosity in drilling fluid is the most important parameter because cutting removal from well are task of viscose fluid. if viscosity of fluid is less than particular value, cutting will settle down in well and drilling operation will be stopped. in this study, synthesis of alumina/polyacrylamide nanocomposite through solution polymerization method was performed. rheological behavior of m...

Curcumin, a poorly water-soluble bioactive compound, was successfully loaded into three different aromatic contents of hydroxypropylmethacrylamide (HPMA)-based polymeric micelles in order to develop water-soluble curcumin nanoformulations (Cur-Nano). The stability study of Cur-Nano was done by keeping the formulations at 4, 30, and 40 °C for 90 days. The physical appearance, curcumin remaining,...

Polymer nano-particles (PNPs) with a near-infrared (NIR) light absorption were prepared by the nano-emulsion method to develop contrast agents for photo-acoustic (PA) imaging. The PNP containing silicon naphthalocyanine showed a high absorption coefficient up to 10(10) M(-1) cm(-1). This is comparable to plasmonic gold nano-particles, which have been studied as PA contrast agents. For the PNP l...

Thin films of nano-particles deposited on substrates are important for new technological applications. Their physical properties depend crucially on particle size and structural inhomogeneity of the deposition. To systematically investigate these dependencies, we apply graph theory and simulations of voltage-driven tunneling conduction. We implement a network model of nano-particle films, based...

The sol-gel method was used to prepare SiO(2) thin films co-doped with In(2)O(3) nano-particles and Eu(3+). The formation of nano-sized In(2)O(3) particles after annealing at 900 °C was confirmed by the x-ray diffraction technique. A novel phase transition from a hexagonal rhombic centered to a body centered cubic structure of In(2)O(3) nano-particles was observed at around 1100 °C. It is found...

This work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. One application of nanotechnology is in improvement of available treatments for various diseases. Deferasirox (ICL670 or Exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. In the present work, deferasirox was prepared in nano size...

A spectral smoothed boundary phase-field model is implemented to study lithium (Li) intercalation in a LixFePO4 nano-particle immersed in a Li(+) rich electrolyte. It takes into account different physical processes on the particle surface, such as heterogeneous nucleation, Li flux and stress-free boundary conditions. We show the nucleation and growth of plate-like Li-rich crystallites along the...

the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...
