Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Partitioning of particulate matter and elements of suburban continental aerosols between fine and coarse modes
(Springer Heidelberg, Heidelberg, 2018)
The results presented in this work demonstrate for the first time a distribution of elements in the spectral analysis of aerosols in the suburban continental Balkan Peninsula. Samples were collected in the suburban area ...
Immobilization of Candida antarctica lipase B onto Purolite(A (R)) MN102 and its application in solvent-free and organic media esterification
(Springer, New York, 2017)
The aim of this study was to develop simple and efficient method for immobilization of Candida antarctica lipase B onto hydrophobic anion exchange resin Purolite(A (R)) MN102 and to apply immobilized catalyst for the ...
Gas holdup in a gassed reciprocating plate column with Rashig rings placed in interplate spaces
(Canadian Society for Chemical Engineering, 2002)
The gas holdup is studies in a gassed reciprocating plate column with the addition of the Rashig rings placed in each interplate space. The gas holdup generally increases with increasing the vibration speed, the superficial ...
Contribution to study of processes on the steel cast-sand mould contact surface during casting
(Elsevier Science B.V., 2000)
The testings involved in this paper were part of a comprehensive research project conducted to find out what complex processes were taking place at metal-mould contact surface. These investigations are of particular ...
Synthesis and Characterization of Novel Urethane-Siloxane Copolymers with a High Content of PCL-PDMS-PCL Segments
(Wiley-Blackwell, Malden, 2011)
Novel polyurethane copolymers derived from 4,4'-methylenediphenyl diisocyanate (MDI), 1,4-butanediol (BD) and alpha, omega-dihydroxy-[poly(caprolactone)-poly (dimethylsiloxane)-poly(caprolactone)] (a, x-dihydroxy( ...
Influence of amine activators and reaction parameters on grafting reaction between polystyrene and starch
(Springer, Dordrecht, 2014)
Polystyrene graft corn starch copolymers (PS-g-starch) were synthesized by emulsion polymerization using sodium dodecylsulfate (SDS) as the emulsifier and potassium persulfate (PPS) as the initiator. Influences of temperature ...
Preparation and characterization of pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Wiley-Blackwell, Hoboken, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were prepared in two steps. Chitosan was first ionically crosslinked with itaconic acid, after which a free radical polymerization and ...
Influence of an antimicrobial treatment on the strength properties of polyamide/elastane weft-knitted fabric
(Wiley, Hoboken, 2007)
Polyamide/elastane weft-knitted fabric, as a suitable compression material, was treated with gentamicin sulfate and a natural antimicrobial preparation of the autochthonous essential oil of Picea abies. The antimicrobial ...
Efficient immobilization of lipase from Candida rugosa by entrapment into poly(N-isopropylacrylamide-co-itaconic acid) hydrogels under mild conditions
(Springer, New York, 2012)
Temperature and pH-sensitive hydrogels, based on N-isopropylacrylamide and itaconic acid, with varying comonomer ratios and crosslinking agent content, were prepared by free radical crosslinking copolymerization. The ...
