On the interdiffusion-based quantum cascade laser
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2002)
Design procedure for the active region of current pumped quantum cascade laser is proposed, so to achieve maximal gain. Starting with an arbitrary smooth potential, a family of isospectral Hamiltonians with predefined ...
Hydrogen evolution reaction from EDTA solutions
(4th Conference of the Yugoslav Materials Research Society, 2002)
An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic ...

Synthesis and structure of colloidal bimetallic nanocrystals: the non-alloying system Ag/Co
(American Chemical Society, 2002)
Monodisperse bimetallic Ag/Co composite nanocrystals have been prepared using colloid chemistry methods. Transmission electron microscopy showed well isolated Ag/Co particles centered around 12 nm in diameter. The composition ...
Cu(II) complexes with a pendant octaazamacrocycle and μ-bonded aromatic carboxylates
(Serbian Chemical Society, 2002)
Three new cationic mixed-ligand Cu(II) complexes with N,N′,N″,N‴-tetrakis(2-pyridylmethyl)-1,4,8,11- tetraazacyclotetradecane (tpmc) and bridging aromatic mono- or dicarboxylate ligands were prepared. Elemental analysis, ...
The estimation of solid copper surface tension in copper sulfate solutions
(Journal of the Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range, the deposition current density remains constant regardless of the deposition overpotential used, At the same time, die larger the deposition ...
Aging of the over-voltage protection elements caused by over-voltages
(Microelectronics Reliability, 2002)
The aim of this work is examining the influence of the number of the activation-over-voltage pulses to the aging of over-voltage protection elements. Both non-linear (gas-filled surge arresters (GFSA), varistors, over-voltage ...
