Wetting properties of hemp fibres modified by plasma treatment
(Taylor & Francis Inc, Philadelphia, 2007)
The influence of dielectric barrier discharge (DBD) on the physico-chemical properties of hemp fibres was studied in this paper. Plasma-modification of hemp fibres was performed at atmospheric pressure. The source of the ...
Synthesis and characterization of bioglass thin films
(Inst Materials Physics, Bucharest, 2007)
We report the successful pulsed laser deposition on medical grade Ti substrates of thin films made of two bioactive glasses in the SiO2 - Na2O- K2O - CaO - MgO - P2O5 system. The films were topographically and chemically ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymer-magnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
Antimicrobial activity of the essential oil and different fractions of Juniperus communis L. and a comparison with some commercial antibiotics / Antimikrobna aktivnost etarskog ulja i različitih frakcija Juniperus communis L. i poređenje sa nekim komercijalnim antibioticima
(Serbian Chemical Society, Belgrade, 2007)
The essential oil of common juniper (Juniperus communis L., from the southern part of Serbia) and its fractions of different composition, as well as commercial antibiotics were used for testing their antimicrobial activity ...
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 of nanosized calcium hydroxyapatite particles by the catalytic decomposition of urea with urease
(Cambridge Univ Press, New York, 2007)
Nanosized calcium hydroxyapatite particles were synthesized by the catalytic decomposition of urea with urease. The influence of the synthesis parameters, i.e., temperature and ratio of the reagents/urease concentrations, ...
Protection of probiotic microorganisms by microencapsulation
(Association of the Chemical Engineers of Serbia, 2007)
Probiotic bacteria are used in the production of fermented dairy foods, pharmaceutical products and health supplements. They play an important role in promoting and maintaining human health. In order, to produce health ...
Photocatalytic degradation of textile dye C.I. reactive orange 16 in TiO2 water suspension by simulated solar light
(Association of the Chemical Engineers of Serbia, 2007)
The photodegradation of C.I. Reactive Orange 16 (RO16), commonly used as a textile dye, was investigated using TiO2 as a catalyst and the sun lamp. The experiments showed that TiO2 and simulated solar light are necessary ...
The influence of thermomechanical treatment and chemical composition on recrystallization of Al-Mg alloys
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behaviour of AlMg3, AlMg4.5Mn and AlMg6Mn alloy plates subjected to different thermomechanical treatments (TMTs), has been studied by means of optical microscopy and hardness measurements. Applied two-stage ...
