Computational studies in the AlPO4-34 system
(Kluwer Academic Publ, Dordrecht, 2001)
The lattice energies of the as-synthesized fluoride-containing chabazite-like aluminophosphate (AlPO4-34F) and of the corresponding metal-substituted materials [MeAPO-34F, Me = Mn(II), Co(II), Ni(II)] have been calculated ...
Structural characteristics of bright copper surfaces
(Journal of Electroanalytical Chemistry, 2001)
In this work, the structures of copper surfaces polished mechanically and polished both mechanically and electrochemically, as well as copper coatings obtained in the presence of basic and top brightening addition agents ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(Kluwer Academic Publ, Dordrecht, 2001)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
Immobilization of invertase on a new type of macroporous glycidyl methacrylate
(Kluwer Academic Publ, Dordrecht, 2001)
Invertase was immobilized via its carbohydrate moiety. The immobilized enzyme has a specific activity of 5500 IU g(-1), with 45% activity yield on immobilization. In a packed bed reactor, 90% 2.5 M sucrose was converted ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Springer-Verlag Berlin, Berlin, 2001)
Two microalloyed steels (Nb/Ti low carbon and V medium carbon) were tested by means of continuous cooling multipass tests on high temperature torsion tester, with aim to investigate the recrystallization kinetics. Multistage ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Serbian Chemical Society, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
A study of HAp/PLLA composite as a substitute for bone powder, using FT-IR spectroscopy
(Elsevier Science Ltd, 2001)
Chemically synthesized hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial was studied in vivo. The biocomposite was implanted into Balb/c Singen mice and after 1 and 3 weeks removed from their organisms and ...
Pressure drop in a countercurrent gas-flowing solids-packed bed contactor
(American Chemical Society, 2001)
The equations for prediction of pressure drop in countercurrent gas-flowing solids-packed bed contactors are proposed. The correlations are based on all available data for various constructions, packing elements, and gas ...
The kinetics of the partial dehydration of gibbsite to activated alumina in a reactor for pneumatic transport
(Serbian Chemical Society, 2001)
The dehidration kinetics of gibbsite to activated alumina was investigated at four different temperatures between 883 K and 943 K in a reactor for pneumatic transport in the dilute two phase flow regime. The first order ...
Delamination detection in woven composite laminates with embedded optical fibers
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
