Solvent and structural effects on the spectral shifts of 5-(substituted phenylazo)-3-cyano-6-hydroxy-1-(2-hydroxyethyl)-4-methyl-2-pyridones
(Elsevier Science Bv, Amsterdam, 2014)
Spectral properties, solvatochromism and azo-hydrazone tautomerism of ten 5-(substituted phenylazo)3-cyano-6-hydroxy-1-(2-hydroxyethyl)-4-methyl-2-pyridones in twenty-two solvents are investigated. For quantitative evaluation ...
A new class of emulsion systems - Fast inverted o/w emulsions: Formulation approach, physical stability and colloidal structure
(Elsevier Science BV, Amsterdam, 2014)
The fast inverted oil-in-water (o/w) emulsions named SWOP (SWitch Oil Phase) emulsions have been investigated with particular reference to physicochemical characteristics. Emulsions (oil-in-water (o/w) and water-in-oil ...
Synthesis, characterization and drug release properties of thermosensitive poly(N-isopropylacrylamide) microgels
(Springer, Dordrecht, 2012)
This study was aimed at optimizing the structure and properties of poly(N-isopropylacrylamide) (PNIPAAm) microgels prepared by inverse suspension polymerization. The influence of the oil-to-water phase ratio, the concentration ...
Nonlinear frequency response analysis of nonisothermal adsorption controlled by macropore diffusion
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this work, a nonlinear frequency response (NFR) approach is used for a theoretical study of nonisothermal adsorption controlled by macropore diffusion (NMD). Based on the nonlinear mathematical model on the particle ...
Spectroscopic characterization of YAG and Nd:YAG single crystals
(IOP Publishing Ltd, Bristol, 2014)
In this paper, we used the Czochralski method to obtain good quality yttrium aluminium garnet (YAG, Y3Al5O12) and yttrium aluminium garnet doped with neodymium (Nd: YAG) crystals. The investigations were based on the growth ...
Removal of Pb2+ Ions from Water by Poly(Acrylamide-co-Sodium Methacrylate) Hydrogels
(Springer, Dordrecht, 2012)
The application of poly(acrylamide-co-sodium methacrylate) (AAm/SMA) hydrogel for the removal of Pb2+ ions from aqueous solutions has been investigated using batch adsorption technique. The extent of adsorption was ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier Science Sa, Lausanne, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
Surrounding gate long channel nanowire MOSFET modelling-extended analysis
(IOP Publishing Ltd, Bristol, 2014)
Based on the approximate solution of Poisson's equation in the case of a p-doped silicon body, an improved current-voltage characteristic model of long-channel cylindrical surrounding-gate Si nanowire MOSFET is proposed. ...
In vitro cell response to Co-containing 1393 bioactive glass
(Elsevier Science Bv, Amsterdam, 2015)
Cobalt ions are known to stimulate angiogenesis via inducing hypoxic conditions and hence are interesting agents to be used in conjunction with bioactive glasses (BGs) in bone tissue engineering approaches. In this work ...
Diagnostic spectroscopic and computer-aided evaluation of malignancy from UV/VIS spectra of clear pleural effusions
(Elsevier, Amsterdam, 2014)
The automated, computer-aided method for differentiation and classification of malignant (M) from benign (B) cases, by analyzing the UV/VIS spectra of pleural effusions is described. It was shown that by two independent ...
