Novel Metal-Organic Frameworks: Microwave Crystallization and Structure
(The Materials Research Society Symposium Proceedings Series, 2005)
Recently, a considerable interest has been directed towards the synthesis of hybrid organic-inorganic solids, which exhibit an enhanced structural versatility, original electronic, magnetic and
optical properties. Also, ...
A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve
(4th FEZA CONFERENCE Collège de France PARIS, 2008)
An efficient removal of the organic component from the as-synthesized solid in order to access the
internal free space is an important step in the final preparation of the porous materials. Recently, kinetic studies of ...
Treatment of heavy metals contaminated solid wastes-Stabilization
(4th European Metallurgical Conference, EMC 2007, 2007)
This paper presents investigation of possibility of heavy metals contaminated solid wastes treatment form Bor Site, Serbia. Presented remediation technology is stabilization, which can effectively reduce content of ...
Equilibrium and kinetic studies of heavy metal retention by hydroxyapatite
(Belgrade : Institute of Technical Sciences of SASA, 2005)
Sorption capacities and kinetics of toxic heavy metals sorption by synthetic, wellcharacterized, hydroxyapatite (HAP) was studied using the batch technique. Initial concentration
of Pb2+, Zn2+, Cd2+ and Sr2+ solutions, ...
Analysis of in vivo substitution of bone tissue by HAp/PLLA composite biomaterial with PLLA of different molecular weights using FTIR spectroscopy
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial with PLLA of 50,000 and 430,000 g/mole molecular weight was studied in vivo. The biocomposite with PLLA of both molecular weights was implanted into mice and ...
Bioethanol Production from Corn Meal Hydrolyzates by Immobilized Saccharomyces cerevisiae var. ellipsoideus
(2008 Joint Central European Congress of the 4th Central European Congress on Food, CEFood 2008 and 6th Croatian Congress of Food Technologists, Biotechnologists and Nutritionists, 2008)
Bioethanol can be produced by fermentation of sugars from waste agricultural materials. In this process immobilized yeast offer advantage over free cell suspension with regard to ethanol productivity, fermentation rate and ...
Further results on singular time delayed system stability
(Institute of Electrical and Electronics Engineers Inc., 2005)
This paper gives sufficient conditions for the stability of linear singular continuous delay systems of the form Eẋ(t) -A 0 x(t) + A 1 X(t -τ). These new, delay-independent conditions are derived using approach based on ...
Uticaj promena parametara neutralizacionog postupka sinteze na fizičko-hemijska svojstva hidroksiapatita
(Beograd : Institut tehničkih nauka SANU, 2007)
Primena hidroksiapatita (HAP-a) u raznim oblastima nauke i tehnologije vrlo je raznovrsna a fizičko-hemijska svojstva prahova moraju se prilagoditi specifičnoj nameni. U ovom radu ispitan je uticaj promena parametara ...
Local heat transfer coefficients during refrigerant R-134a evaporation in a vertical plate heat exchanger
(18th International Congress of Chemical and Process Engineering, CHISA 2008, 2008)
The evaporation heat transfer coefficient of refrigerant R-134a in a vertical plate heat exchanger was investigated. The area of the plate was divided into several segments along the vertical axis. For each of the segments, ...
The antibacterial efficiency of polyester fabrics modified by air RF plasma and silver nanoparticles
(University of Gent : Department of Materials, Textiles and Chemical Engineering, 2009)
The aim of this study was to highlight the possibility of using the air RF plasma for fiber surface activation that can facilitate the deposition of silver nanoparticles from colloid onto the polyester fabrics and thus, ...
