Recycled wool-based nonwoven material as an oil sorbent
(Amer Chemical Soc, Washington, 2003)
The aim of this study was to highlight the possibility of using recycled wool-based nonwoven material as a sorbent in an oil spill cleanup. This material sorbed higher amounts of base oil SN 150 than diesel or crude oil ...
Efficiency of membrane extraction of phenol-4-aminoantipyrine complex with n-alcohols
(Elsevier, Amsterdam, 2004)
In this study, the membrane extraction of phenol-4-aminoantipyrine complex with the series of aliphatic alcohols was investigated by monitoring the efficiency of the process. A commercial polysulphone hollow-fiber membrane ...
Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly(GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the highest ...

In this paper a new analytical model of a silicon Thin Film Transistor (Si TFT) with cylindrical source and drain, is presented. In first part of the text. some basic TFT characteristics and possible applications are ...
Volcano plots along intermetallic hypo-hyper-d-electronic phase diagrams and electrocatalysis for hydrogen electrode reactions
(Journal of New Materials for Electrochemical Systems, 2000)
The nature, causes and consequences of the existence of volcano plots along transition series with resulting theoretical conclusions have been extended on the Brewer hypo-hyper-d-electronic combinations of transition metal ...
Membrane interactions of ternary phospholipid/cholesterol bilayers and encapsulation efficiencies of a RIP II protein
(Elsevier Science Bv, Amsterdam, 2008)
Membrane interactions of liposomes of ternary phospholipid/cholesterol bilayers are investigated. These interactions lead to discoidal deformations and regular aggregations and are strongly enhanced by the presence of ...
Extraction of hyperforin and adhyperforin from St. John's Wort (Hypericum perforatum L.) by supercritical carbon dioxide
(Elsevier, Amsterdam, 2008)
St. John's Wort (Hypericum perforatum L.) was extracted with supercritical carbon dioxide (SC CO2) under 10, 15 and 20 MPa and at 313 and 323 K. The influence Of SC CO2 density (400-800 kg/m(3)) was examined with respect ...
Polyaniline as possible anode materials for the lead acid batteries
(Elsevier Science Bv, Amsterdam, 2008)
Electrochemically formed thin film polyaniline (PANI) anode and lead dioxide (PbO2) cathode, obtained from sulfuric acid solution, for potential applications as electrode materials in PANI vertical bar H2SO4 vertical bar ...
Lipase-catalyzed biodiesel synthesis with different acyl acceptors / Primena novih acil akceptora u procesu enzimski katalizovane sinteze biodizela
(Faculty of Technology, Novi Sad, 2008)
Biodiesel is an alternative fuel for diesel engine that is environmentally acceptable. Conventionally, biodiesel is produced by transesterification of triglycerides and short alcohols in the presence of an acid or an ...
An improved method for thermal stability behavior characterization of silicon carbide/cordierite composite material
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950°C, ...
