Elastic percolation of swollen polyacrylamide (PAAm)-multiwall carbon nanotubes composite
(Taylor & Francis Ltd, 2012)
Polyacrylamide (PAAm)-multiwalled carbon nanotube (MWNT) composites were prepared via free radical cross-linking copolymerization with different amounts of MWNTs varying in the range between 0.1 and 50 wt%. The mechanical ...
Broadband impedance matching via lossless unsymmetrical lattice networks
(Elsevier GMBH Urban & Fischer Verlag, 2012)
In this paper a broadband impedance matching network (equalizer) design algorithm has been proposed. In the equalizer a lossless unsymmetrical lattice network has been utilized. The branch impedances of the lattice network ...
Social media integration in higher education cross-course google plus integration shown in the example of a master's degree course in management
(Elsevier Science Bv, 2012)
Nearly all web services can be adapted for educational use Although some nistructors do use social media for their courses privacy concerns always throttle the 'need' of instructors for social media. Google Plus seems to ...
PAAm-kappa carrageenan composites: drying and swelling with various kappa carrageenan contents
(Polish Acad Sciences Inst Physics, 2012)
The purpose of this study is to discuss the role of kappa-carrageenan (kappa-car) in the drying and swelling of polyacrylamide (PAAm)-kappa-car composite. The fluorescence intensity of pyranine increased and decreased as ...
Film Formation of Poly (methyl methacrylate) Latex With Pyrene Functional Poly (divinylbenzene) Microspheres Prepared by Click Chemistry
(Wiley-Blackwell, 2011)
This work reports on the application of steady state fluorescence (SSF) technique for studying film formation from poly(methyl methacrylate) (PMMA) latex and poly(divinylbenzene) (PDVB) microsphere composites. Pyrene (P) ...
Studies on Drying and Swelling of PAAm-NIPA Composites in Various Compositions
(Wiley-Blackwell, 2011)
The steady-state fluorescence technique was introduced for studying the drying and swelling of disc-shaped PAAm-NIPA composites. Disc-shaped gels were formed with various acrylamides (AAm) and N-isopropylacrylamides (NIPA) ...
Drying of Polyacrylamide Composite Gels Formed with Various Kappa- Carrageenan Content
(Springer/Plenum Publishers, 2011)
Drying of polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composite gels were monitored by using steady-state fluorescence technique. Disc shaped gels were formed from acrylamide (AAm) and N N'- methylenebisacrylamide(Bis) ...
Derivation of the optical constants of spin coated CeO2-TiO2-ZrO2 thin films prepared by sol-gel route
(Pergamon-Elsevier Science Ltd, 2011)
Ternary thin films of cerium titanium zirconium mixed oxide were prepared by the sol-gel process and deposited by a spin coating technique at different spin speeds (1000-4000 rpm). Ceric ammonium nitrate ce(NO3)(6)(NH4)(2) ...
Reliability-Oriented bioinformatic networks visualization
(Oxford University Press, 2011)
We present our protein-protein interaction (PPI) network visualization system RobinViz (reliability-oriented bioinformatic networks visualization). Clustering the PPI network based on gene ontology (GO) annotations or ...
Do structural breaks in exchange rate volatility matter? Evidence from Asia-Pacific currencies
(Bilgesel Yayincilik San & Tic Ltd, 2011)
Using the U.S. dollar exchange rate return series of three major Asia-Pacific currencies this paper investigates the empirical relevance of structural breaks in exchange rate volatilities. We find significant evidence of ...
