Sn–9Zn solder joints containing Ag nano particles were prepared by mechanically mixing Ag nano particles (0.3, 0.5 and 1 wt%) with Sn–9Zn solder paste. In the monolithic Sn–Zn solder joints, scallop-shaped AuZn3 intermetallic compound layers were found at their interfaces. However, after the addition of Ag nano particles, an additional uniform AgZn3 intermetallic compound layer well adhered to ...

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...

In this study, multifunctional theranostic agents for photoacoustic (PA), ultrasound (US), fluorescent imaging, and for therapeutic drug delivery were developed and tested. These agents consisted of a shell made from a biodegradable Poly(lactide-co-glycolic acid) (PLGA) polymer, loaded with perfluorohexane (PFH) liquid and gold nanoparticles (GNPs) in the core, and lipophilic carbocyanines fluo...

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...

Silver nanoparticles offer highly attractive properties for many applications, however concern has been raised over the possible toxicity of this material in environmental systems. While it is thought that the release of Ag(+) can play a crucial role in this toxicity, the mechanism by which the oxidative dissolution of nano-silver occurs is not yet understood. Here we address this through the e...

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...
