The detailed characterization of nanometer-thin film structures is key to the in-depth understanding and property control such objects. Here we present analysis Co/Cu/Co multilayer grown on covered by thin Ta layers at individual layer thicknesses below 5 nm. prime focus was detect threshold Cu thickness required separate effectively magnetic Co layer. We found that a 4 nm can layers, but 2.8 n...

Real-time size, mass and number particle concentrations, and emission rates in university laboratories producing nanoparticles by scalable flame spray pyrolysis are quantified. Measurements were conducted in four laboratories using various technological set-ups and during production of particles of a range of compositions with differing physical-chemical properties, from NaCl salt, BiPO(4), CaS...

Nowadays, over 300 tons of Au are used in electronic equipment each year with other precious and strategic metals such as Ag, Pt, Pd, Cu, Nb, Ta, etc.. After the use-phase, the electronic devices become electronic waste (e-waste); consequently it is important to consider e-waste as a secondary supply for the recovery of these metals. This paper presents the recovery of Au, Ag, Cu and Nb from PC...
