A coaxial transmission line was constructed, characterized, and calibrated for the frequency dependent measurement of complex relative permeability (l r) and complex permittivity (e r). The permeability of Ni powder with a grain size of < 1 lm was measured as a function of packing density to verify the system performance. 8–10 nm diameter Co nanoparticles were synthesized, dried to a powder, an...

Solution Precursor Plasma Spray (SPPS) technique is an emergent technique which offers significant performance advantages with various functional coatings like YSZ, ZnFe2O4, LSM, metal-doped ZnO, etc. Apart from the above capabilities, efforts towards development of an innovative hybrid approach through simultaneous deposition of powder and solution resulted in coatings with unique microstructu...

This paper deals with production of hard metal by powder metallurgy and its effect on the environment. Hard is a composite material that consists tungsten carbide as refractory phase cobalt or nickel soft binder phase. It cannot be produced classical casting technology. Owing to excellent properties, such high hardness, wear heat resistance etc., can applied in variety industrial fields. Powder...

the nanocrystallization of co67fe4cr7si8b14 amorphous ribbons which prepared by planar flow melt spinning process (pfms) was investigated. crystallization of the ribbons was studied by differential thermal analysis (dta), x-ray diffraction (xrd) and transmission electron microscopy (tem). the dta result of amorphous ribbon at heating rate of 10˚c/min showedoccurrence of phase transitions in two...

The increasing interest in epidermal patches for wearable monitoring makes it urgent to move toward “greener” and recyclable materials printed electronics. However, combining scalable fabrication, stretchable function, material architecture is challenging achieve. Here, this article introduces a printable biphasic liquid metal (LM)-based composite that combines excellent electrical conductivity...

Multifunctional composite nanoprobes consisting of iron oxide nanoparticles linked to silver and gold nanoparticles, Ag-Magnetite and Au-Magnetite, respectively, were introduced by endocytic uptake into cultured fibroblast cells. The cells containing the non-toxic nanoprobes were shown to be displaceable in an external magnetic field and can be manipulated in microfluidic channels. The distribu...
