Preparation and characterization of iron(III) phosphate-oxalate using 1,2-diaminopropane as the structure-directing agent
(Elsevier, Amsterdam, 2002)
Iron(III) phosphate-oxalate (FePO-DAP) crystallizes from a clear solution containing 1,2-diaminopropane (DAP) and oxalic acid at 120 degreesC under hydrothermal conditions. Doubly protonated DAP is present inside a large ...

Gain optimization in electrically pumped AlGaAs quantum cascade lasers
(Optical Soc Amer, Washington, 2002)
The design of the active region of a current-pumped quantum-cascade laser to achieve maximal gain is proposed. Starting with an arbitrary smooth potential, a family of isospectral Hamiltonians with a predefined energy ...
Comparative reflection and structural analyses of copper and zinc coatings electrodeposited from acid sulfate solutions without and with additives
(Elsevier, 2002)
Reflection and structural analyses of different copper and zinc coatings were performed. The coatings of copper obtained were from acid sulfate solutions in the absence and presence of thiourea. The coatings of zinc were ...
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 ...
Modeling of coating optical fibers with polymer-magnetic powder composite coating
(International Institute for the Science of Sintering, Beograd, 2002)
A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological ...
Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Chevron defect at the intersection of grain boundaries with free surfaces in Au
(American Physical Society, 2002)
We have identified a new defect at the intersection between grain boundaries and surfaces in Au using
atomic resolution transmission electron microscopy. At the junction line of 90
h110i tilt grain boundaries

Gas holdup in a gassed reciprocating plate column with Rashig rings placed in interplate spaces
(Canadian Society for Chemical Engineering, 2002)
The gas holdup is studies in a gassed reciprocating plate column with the addition of the Rashig rings placed in each interplate space. The gas holdup generally increases with increasing the vibration speed, the superficial ...
