Nano particles have a wide range of applications such as electronics, catalysis, chemistry energy and medicine and have thus gained commercial acceptance [1]. Besides improving their functionality, the use of nano technology can result in the production of textiles with completely novel properties or the combination of various functions [2]. Such multifunctional textiles include antistatic text...

Nano-sized TiCx/2009Al composites (with 5, 7, and 9 vol% TiCx) were fabricated via the combustion synthesis of the 2009Al-Ti-CNTs system combined with vacuum hot pressing followed by hot extrusion. In the present study, CNTs were used as the carbon source to synthesize nano-sized TiCx particles. An attempt was made to correlate the effect of ground CNTs by milling and the distribution of synthe...

Chan Nano-sized, nonreacting, noncoarsening Al2O3 particles have been incorporated into eutectic Sn–Zn solder alloys to investigate the microstructure, hardness and shear strength on Au/Ni metallized Cu pads ball grid...

in this study, aluminum (al) matrix reinforced with micro-particles (30 µm) and nano-particles (50 nm) boron carbide (b4c) were used to prepare al-2.5%wt., b4c nano-composite and micro-composite, respectively, using mechanical alloying method. the mixed powders were mechanically milled at 5, 10, 15 and 20 hrs. the xrd results indicated that the crystallite sizes of both the micro-composite and ...

A new family of biodegradable polymer/bioactive glass (BG) composite materials has emerged based on the availability of nano-sized bioactive particles. Such novel biocomposites can have enhanced performance, in terms of mechanical properties and bioactivity, and they can be designed to be used in bone regeneration approaches. In this work, membranes of chitosan (CTS) and chitosan with bioactive...

In this paper we assume determination of pseudo-viscosity coefficients of visco-elastic non-Newtonian fluid flow directly near the cooperating micro-bearing surface. We show the constitutive stress-strain dependencies of nonNewtonian visco-elastic media with regard to the content of addition of nano-particles. The greater content of nano-particles and influences of superficial layer of cooperat...

Herein we report nano-molding proteins for the fabrication of protein PRINT particles of monodisperse size and shape. Lyophilized protein particles are generally highly dispersed in particle size, aggregated, and often made through costly and complicated processes. Attempts to engineer monodisperse, discrete protein particles using wet-milling, spray-freeze-drying, microemulsion, or super criti...

Silver nano-particles have been used for antibacterial purpose and it is also believed to have removal of odorous compounds, oxidation capacity as a metal catalyst. In this study, silver nano-particles in nano sizes (5-30 nm) were prepared on the surface of NaHCO3, the supporting material, using a sputtering method that provided high silver content and minimized conglomerating problems observed...

Nano-sized, nonreacting, noncoarsening ZrO2 particles reinforced Sn–3.0 wt%Ag–0.5 wt%Cu composite solders were prepared by mechanically dispersing ZrO2 nano-particles into Sn–Ag–Cu solder. The interfacial morphology of unreinforced Sn–Ag–Cu solder and solder joints containing ZrO2 nano-particles with Au/Ni metallized Cu pads on ball grid array (BGA) substrates and the distribution of reinforcin...
