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 ...
Microstructure and pitting corrosion resistance of annealed duplex stainless steel
(Elsevier Ltd, 2006)
The transition from metastable to stable pitting was studied in 0.5 M NaCl water solution for two cast duplex stainless steels under different microstructural conditions achieved by annealing in the range from 900 °C to ...
Structure sensitivity of dimethylamine deep oxidation over Pt/Al2O3 catalysts
(Elsevier, 2009)
The deep oxidation of dimethylamine (DMA) was studied over Pt/Al2O3 catalysts with small (1 nm) and large (7.8-15.5 nm) Pt crystallite sizes. The turnover frequency (TOF) was higher for the large than for the small Pt ...
Thermal properties of textile fabrics made of natural and regenerated cellulose fibers
(Elsevier Sci Ltd, Oxford, 2008)
Cotton (cellulose) and viscose (regenerated cellulose) fibers are commonly applied in clothing textile fabrics. Thanks to the unique hemp (lignocellulose) fibre properties and its ecological benefits (biodegradability), ...
Fermentation of wheat and triticale hydrolysates: A comparative study
(Elsevier Sci Ltd, Oxford, 2009)
In bioethanol production four wheat varieties were investigated: NS 40S, Renesansa, Rapsodija and Dragana, as well as four triticale varieties: Oganj, Jutro, Odisej and NST 21/06. The samples were grinded and mixed with ...
