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 ...

Metal-organic frameworks are nano-porous adsorbents of relevance to gas separation and catalysis, and separation of oxygen from air is essential to diverse industrial applications. The ferrous salt of 2,5-dihydroxy-terephthalic acid, a metal-organic framework of the MOF74 family, can selectively adsorb oxygen in a manner that defies the classical picture: adsorption sites either do or do not sh...

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...

Lycurgus cup [ 1 ] created by ancient Romans 2000 years ago can appear different colors depending on the direction of light illumination in which it is viewed due to metal nanoparticle optical scattering. It has inspired nanoplasmonics research over the past decade. [ 2–5 ] Here we present a nanoscale Lycurgus cup arrays (nanoLCA) device that has the property of appearing green when light is sh...

The DNA structure is an ideal building block for the construction of functional nano-objects. In this direction, metal coordinating base pairs (ligandosides) are an appealing tool for the future specific functionalization of such nano-objects. We present here a study, in which we combine the metal ion coordinating pyrazole ligandoside with the interstrand crosslinking salen ligandoside system. ...

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...

Noble metal nanoslit structure has attracted an increasing interest in nanoscale photonic devices, and bio applications. However, methods typically used for fabricating nano-sized slit, such as, e-beam direct etching, template-assisted photolithography, and nano-imprint lithography, have low yield and are limited to sub-nano sized slit. In this work, we observed that slit width of Au metal is g...
