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 ...
Gibbson: Peptide plane as a unique biological nanostructure
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper we describe the properties of peptide plane of amino acids from a biophysical point of view. We use Lagrange's equations to calculate the energy states of peptide plain and to explain its biophysical proper-ties. ...
Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
Classical and quantum information channels in protein chain
(Trans Tech Publications Ltd, Stafa-Zurich, 2006)
Investigation of the properties of peptide plane in protein chain from both classical and quantum approach is presented. We calculated interatomic force constants for peptide plane and hydrogen bonds between peptide planes ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
Comparative Efficacy Analysis of Biomaterials and Soft Lasers in Repair of Bone Defects
(The Journal of Oral Laser Applications, 2007)
Purpose: The efficacy of soft laser application in the treatment of experimentally created bone defects in rat mandibles filled with biocomposite BCP/PLGA (bicalcium phosphate/polylactide–co-glycolide) was analyzed. Materials ...
Uloga sintetičkih biomaterijala u procesu regeneracije resorbovane alveolarne kosti / The role of synthetic biomaterials in resorptive alveolar bone regeneration
(Belgrade : Association of the Chemical Engineers of Serbia, 2007)
Gubitak koštanog tkiva, usled resorpcije viličnih kostiju, ima značajno mesto u stomatologiji. U cilju rešavanja problema deficita koštanog tkiva nastalih resorpcijom alveolarne kosti pristupilo se primeni sintetičkih ...
Encapsulation devices for Vitamin C
(Hauppauge, N. Y.: Nova Science Publishers, Inc., 2009)
Vitamin C, also known as ascorbic acid, is a very important water-soluble vitamin. It is essential for preserving optimal health and it is used by the body for many purposes. Vitamin C promotes collagen biosynthesis, ...
Elektrohemijska sinteza i karakterizacija elektrode od polianilina za potencijalnu upotrebu u elektrohemijskim izvorima energije / Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Engineering Society for Corrosion, Belgrade, Serbia, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 moldm-3 HCl and 0.25 mol dm-3 aniline monomer. ...
Ultrasound modifications of physical properties of BaTiO3 powders
(Society of Physical Chemists of Serbia, 2006)
The starting BaTiO3 powder was prepared by solid state reaction, and then modified by ultrasound into powders with different physical characteristics. The prepared barium titanate powders were characterized by X-ray powder ...
