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 ...
Formation of nanocrystalline transition-metal ferrites inside a silica matrix
(Wiley, Hoboken, 2002)
Nanocrystalline transition-metal ferrites were synthesized inside an amorphous silica matrix by the sol-gel method. The formation of spinel ferrites began above 400degreesC, giving fine particles of about 10 nm at 800degreesC. ...
Influence of plying on singles hemp yarn properties / Uticaj končanja na svojstva pređa od konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2002)
The return to garments that provide the maximum of natural properties became a new trend contributing significantly to environmental protection. In this situation hemp as a historical and controversial fiber gained the new ...
Speciation of water-soluble organic aerosol at Skukuza, South Africa, during SAFARI 2000
(Book of Abstracts / 10th scientfic conference of the international association of meteorology of atmospheric sciences (IAMAS) commission for atmospheric chemistry and global pollution (CACGP), 7th scientific conference of the international global atmospheric chemistry project (IGAC) - Joint International Symposium on Atmospheric Chemistry within the Earth System: From Regional Pollution to Global Climate Change, September 18-25 (2002) Crete, Greece, 2002)
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
Reflection and structural characteristics of semi-bright and mirror bright nickel coatings
(Journal of the Serbian Chemical Society, 2002)
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening, addition agent arc examined. It is shown ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Serbian Chemical Society, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
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 influence of electroless plated chromium on printing properties of aluminum offset printing plate
(Journal of the Serbian Chemical Society, 2002)
A method for the improvement of the printing properties of offset printing forms is presented. Specimens of technical aluminum were electrochemically roughened and treated in different alkaline solutions of chromium chloride ...
