Surface characterization and properties of keratin fibers treated with low-temperature plasmas
(Polymer Surface Modification: Relevance to Adhesion, Volume 3, 2004)
The relation between shrink-resistance properties and surface changes (wettability, atomic chemical composition and topographical or morphological) induced by low-temperature plasmas (LTPs) has been studied in depth. For ...
The influence of a cryoprotective medium containing glycerol on the lyophilization of lactic acid bacteria / Uticaj krioprotektivnog medijuma sa glicerolom na liofilizaciju bakterija mlečne kiseline
(Serbian Chemical Society, 2001)
The aims of lyophilization (freeze-drying) of lactic acid bacteria are to preserve pure cultures or to prepare starters for the dairy industry. In both cases, the choice of the cryoprotectant is very important. In this ...
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 ...
The alternative methods of preparing wool for printing / Alternativni postupci pripreme vune za štampanje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2002)
The adsorbable organohalogens (AOX) loading of effluent must be set against the high efficiency of chlorination in preparing wool for printing Therefore, there have been a number of research attempts to develop alternative ...
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 ...
Alginate-immobilized lipase by electrostatic extrusion for the purpose of palm oil hydrolysis in lecithin/isooctane system
(Elsevier Sci Ltd, Oxford, 2002)
Lipase from Candida rugosa was immobilized in alginate beads for possible application in non-aqueous or microaqueous reaction systems. An electrostatic droplet generation technique was used for production of small diameter ...
Size and surface effects on the MRI relaxivity of manganese ferrite nanoparticle contrast agents
(Amer Chemical Soc, Washington, 2007)
Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches. First, we applied a ligand exchange in order to form a ...
Primena savremenih postupaka modifikovanja površine tekstilnih vlakana radi postizanja multifunkcionalnih svojstava tekstilnog materijala / Use of modern methods of fibre surface modification to obtain the multifunctional properties of textile materials
(Association of Chemical Engineers of Serbia, 2003)
Savremena obrada tekstilnog materijala ima za cilj postizanje zahtevanog efekta uz ograničavanje modifikovanja samo na površinu vlakna. U poslednje vreme se znatna pažnja poklanja fizičkim postupcima obrade, medu kojima ...
Design, implementation and testing of the controller for the terabit packet switch
(IEEE, New York, 2006)
The sequential greedy scheduling (SGS) is a scalable algorithm that provides non-blocking in high-capacity packet switches. We implemented the SGS scheduler in the FPGA device, and examined its scalability and speed. Then, ...
Synthesis of thermoplastic poly(ester-olefin) elastomers / Sinteza termoplastičnih poli(estar-olefinskih) elastomera
(Association of Chemical Engineers of Serbia, 2004)
A series of thermoplastic poly(ester-olefin) elastomers, based on poly(ethylene-stat-butylene), HO-PEB-OH, as the soft segment and poly (butylene terephthalate), PBT, as the hard segment, were synthesized by a catalyzed ...
