nanocrystalline zno particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. characterizations were carried out by x-ray diff...

laser-tissue interaction is of great interest due to its significant application in biomedical optics in both diagnostic and treatment purposes. major aspects of the laser-tissue interaction which has to be considered in biomedical studies are the thermal properties of the tissue and the thermal changes caused by the interaction of light and tissue. in this review paper the effects of light on ...

Background: Pineapple juice processing is an art of preservation, and the processing technologies play important role in pineapple juice quality. Therefore, this study aimed to explore the potential impacts of non-thermal processing methods on the physicochemical, bioactive, and microbiological properties of fresh pineapple juice. Methods: Extracted juices were subjected to several non-thermal...

master moulds are used to cast copper anode moulds. these iron moulds are made of grey or nodular cast irons. according to desirable properties of ductile irons, it was expected that ductile cast iron moulds could have performed their nominal life. but in service, these moulds have not performed their nominal life and they have experienced premature failures due to warping and cracking. also gr...

Hu, Jiuning Ph.D., Purdue University, May 2015. Transport studies in graphenebased materials and structures. Major Professor: Yong P. Chen. Graphene, a single atomic layer of graphite, has emerged as one of the most attractive materials in recent years for its many unique and excellent properties, inviting a broad area of fundamental studies and applications. In this thesis, we present some the...

In this study, we analysed the thermal performance, thermal stability and optimum design analyses of a longitudinal, rectangular fin with temperature-dependent, thermal properties and internal heat generation under multi-boiling heat transfer using Haar wavelet collocation method. The effects of the key and controlling parameters on the thermal performance of the fin are investigated. The therm...

The mechanical properties of microscopic particles have been a heated research object for it takes the deformation of micro-beads in the microfluidic environment into account. Sufficient knowledge on mechanical properties of micro-beads would lead to better device design and application for cell mechanics, tissue engineering, etc. The physical properties of alginate beads were examined both in ...

In this research, an in-house code which uses the molecular dynamics method to study the flow of different nanofluids in the copper nanochannel and computes the thermo-physicals properties has been developed. The flow of nanofluids has been studied from hydro-thermally viewpoint and temperature jump at the wall has been applied. Parametric study to consider the effect of different parametric su...

Polypropylene / polystyrene blends containing montmorillonite (MMT) were prepared using a twin screw extruder followed by fiber spinning. The melt intercalation of PP and PS alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (MPP). The crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (PP/PS) nan...
