Synthesis and characterization of biodegradable aliphatic copolyesters with poly(tetramethylene oxide) soft segments
(Wiley, Hoboken, 2007)
A series of aliphatic poly(ether-ester)s based on flexible poly(tetramethylene oxide) (PTMO) and hard poly (butylene succinate) (PBS) segments were synthesized by the catalyzed two-step transesterification reaction of ...
Synthesis and characterization of biodegradable poly(butylene succinate-co-butylene adipate)s
(Elsevier Sci Ltd, Oxford, 2001)
A series of high molecular weight polyesters, poly(butylene succinate-co-butylene adipate)s was prepared from dimethyl succinate, dimethyl adipate and 1,4-butanediol by catalyzed transesterification in the melt. The ...
The study of coloration and antibacterial efficiency of corona activated dyed polyamide and polyester fabrics loaded with Ag nanoparticles
(Korean Fiber Soc, Seoul, 2009)
The aim of this study was to examine the influence of dyeing on antibacterial efficiency of corona activated polyamide and polyester fabrics loaded with colloidal Ag nanoparticles as well as the influence of the presence ...
Stress analysis in hydroxyapatite/poly-L-lactide composite biomaterials
(Elsevier, Amsterdam, 2001)
A three-dimensional (3D) finite element (FE) analysis of the stress concentration factor (SCF) in biocomposite model cell has been performed. The model composite consisted of a hydroxyapatite hard particle (HAp) embedded ...
Influence of the semiconductor doping level on the carrier surface density in an AlGaN/GaN MODFET channel
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
In this paper the influence of doping level in AlGaN and GaN on the carriers surface density in a channel of modulation doped field effect transistors (MODFETs) has been investigated. The carriers concentration profile in ...
Interface shape and distribution of solute during Vertical Bridgman growth of Al-Cu alloy
(Elsevier, Amsterdam, 2002)
Results presented in this paper contribute to investigation of the influence of solidification rate (R) and the initial concentration of solute (C-o) on the interface shape and the distribution of the solute. Solidification ...
Bulk etching rate of LR115 detectors
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The thickness of the layer of LR115 detector removed during etching was measured with a very precise instrument. Dependence of the bulk etch rate on temperature of the etching solution was investigated. It has been found ...
The study of iron chlorination from bauxite for its enrichment
(Munksgaard Int Publ Ltd, Copenhagen, 2001)
The possibility of enriching bauxite by removing iron in low-temperature chlorination by gaseous chlorine in the presence of carbon as a reducer from coke and carbon monoxide, is investigated. Thermodynamic analysis points ...
Optical fibers with composite magnetic coating for magnetic field sensing
(Elsevier Science Bv, Amsterdam, 2004)
