the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

Since meshfree particle methods have advantages on simulating the problems involving extremely large deformations, fractures etc., they become attractive options to be used in the hierarchical multiscale modeling to approximate a large number of atoms. We propose a nanoscale meshfree particle method with the implementation of the quasicontinuum technique in this paper. The intrinsic properties ...

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...

Porous bone tissue engineering scaffolds were fabricated using both nano hydroxyapatite (nano HA) powder (20 nm average particle size) and micro HA powder (10 microm average particle size), resulting in sintered scaffolds of 59 vol% porosity and 8.6 +/- 1.9 microm average grain size and 72 vol% porosity and 588 +/- 55nm average grain size, respectively. Scanning electron microscopy was used to ...

The electrostatic hazards of nitramine explosives (RDX, HMX) were assessed in this paper. The resistivities of different particle-size RDX and HMX were tested by a device designed and manufactured according to the standard ISO/ IEC 80079-20-2:2016. This work shows that the resistivities of uncompacted RDX and HMX increase as the particle size decreases. Charging characteristics test experiments...

We report a technique to realize reconfigurable colloidal crystals by using the controlled motion of particle defects above an externally modulated magnetic substrate. The transport of particles is induced by applying a uniform rotating magnetic field to a ferrite garnet film characterized by a periodic lattice of magnetic bubbles. For filling factor larger than one colloid per bubble domain, t...

The objective of present work was development of felodipine nano emulsion formulations using sesame oil as sole lipid phase by high pressure homogenization technique. A combination of non-ionic surfactants was used based on HLB (Hydrophilic lipophilic balance) values. The resultant nano emulsions were characterized for particle size, zeta potential. The particle size for the optimized nano emul...

To study the anomalous heat effect of Nibased binary-metal-nano-powder samples by gas-phase hydrogen isotope absorption/desorption, three kinds of samples CNZ, CNZ-II and NZ were tested for the temperature range 300-573 K. The highest excess heat power, ca. 2W/g-Ni was obtained with CNZ at 573 K. Peculiar H(D)-isotopic effect and sudden heat sink by abrupt H(D)-desorption were observed. The hea...

This paper uses the molecular dynamics method to investigate the influence of chemical bonds on the mechanical behaviour of nanotube–polyethylene composites subjected to nano-particle impacts. In the analysis, carbon nanotubes (CNTs) were incorporated into the polyethylene (PE) matrix in two ways, with and without radical centres, so that the resulting nano-composites had two corresponding prop...

The acicular Mn-Zn ferrite fine particles composed of 65.6 mol% Fe, 21.9 mol% Mn and 12.5 mol% Zn were made. These Mn-Zn femte particles were etched in IN-HC1 solution for 3hrs.. The fine particle was made up of several crystallites whose long axis were 0.2-1.0ptt1, and arranged to (31 1) direction. These fine particles were pressed with applying magnetic field. The oriented Mn-Zn ferrites were...
