Molecular weight distribution and functional group profiles of TEMPO-oxidized lyocell fibers
(Elsevier Sci Ltd, Oxford, 2013)
The effects of TEMPO-mediated oxidation, performed with NaClO, a catalytic amount of NaBr, and 2,2',6,6'-tetramethylpiperidine-1-oxy radical (TEMPO), were studied on lyocell fibers by means of GPC using multiple detection ...
Oxidized and Ethylenediamine-Functionalized Multi-Walled Carbon Nanotubes for the Separation of Low Concentration Arsenate from Water
(Taylor & Francis Inc, Philadelphia, 2013)
In this work multiwalled carbon nanotubes (MWCNTs) modified by oxidation (o-MWCNTs) and by aminofunctionalization (e-MWCNTs) were examined as potential adsorbents for arsenate removal from water. Adsorption characteristics ...
Properties and drug release profile of poly(N-isopropylacrylamide) microgels functionalized with maleic anhydride and alginate
(Springer, New York, 2013)
This study highlights the advantages of functionalized poly(N-isopropylacrylamide) (PNIPAAm) microgels over pure PNIPAAm microgels in terms of polymer network properties and drug release profiles. PNIPAAm network was ...
Integrated production of lactic acid and biomass on distillery stillage
(Springer, New York, 2013)
The possibilities of parallel lactic acid and biomass production in batch and fed-batch fermentation on distillery stillage from bioethanol production were studied. The highest lactic acid yield and productivity of 92.3 % ...
Effect of austempering temperature on cavitation behaviour of unalloyed ADI material
(Elsevier Science Inc, New York, 2013)
This paper provides an in-depth study and description of cavitation damage and microstructural changes in two types of unalloyed austempered ductile iron (ADI). ADI materials used were austempered at 300 and 400 degrees C ...
Distillery Stillage as a New Substrate for Lactic Acid Production in Batch and Fed-batch Fermentation
(Aidic Servizi Srl, Milano, 2013)
Lactic acid and biomass production on distillery stillage - a by-product of bioethanol industry - was studied in this paper. Batch and fed-batch fermentation strategies for lactic acid production on distillery stillage ...
Evaluation of periodic processes with two modulated inputs based on nonlinear frequency response analysis. Case study: CSTR with modulation of the inlet concentration and flow-rate
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In our previous work, a new, fast and easy, nonlinear frequency response method for analysing potential improvements of reactor performance by forced periodic operation was presented. This method, which is based on Volterra ...
Polymer bonded magnetic composites based on Nd-Fe-B / Polimerni magnetni kompoziti na bazi Nd-Fe-B
(Inženjersko društvo za koroziju, Beograd, 2013)
Various types and contents of magnetic powder and polymer matrix induce different mechanical, magnetic, electrical and optical properties of final composite material. The strong influence of relatively small amounts of ...
