CdS Nanoclusters: Synthesis, Characterization, Size Dependent Oscillator Strength, Temperature Shift of the Excitonic Transition Energy, and Reversible Absorbance Shift
Tobias Vossmeyer,Lynne Katsikas,Michael Giersig,Ivanka G. Popović,K. Diesner,Abdelkrim Chemseddine,Alexander Eychmueller,Horst Weller +7 more
TL;DR: In this paper, the size-dependent shift of the Is-Is excitonic transition is in agreement with the tight-binding theory and the pseudopotential theory, and as expected by quantum mechanical calculations the oscillator strength of the transition increases proportional to 1 /r3.
Journal ArticleDOI
The thermogravimetric analysis of some polysiloxanes
TL;DR: In this paper, the effect of the presence of hydrido-substituents and/or vinyl end-groups on the thermal and thermo-oxidative stability of polysiloxanes was determined.
Journal ArticleDOI
Improvement of epoxy resin properties by incorporation of TiO2 nanoparticles surface modified with gallic acid esters
Tijana S. Radoman,Jasna V. Džunuzović,Katarina Jeremic,Branimir N. Grgur,Dejan Miličević,Ivanka G. Popović,Enis S. Džunuzović +6 more
TL;DR: In this article, three gallic acid esters, having different hydrophobic part, were used for surface modification of the synthesized TiO 2 nanoparticles: propyl, hexyl and lauryl gallate.
Journal ArticleDOI
The forecasting of municipal waste generation using artificial neural networks and sustainability indicators
TL;DR: It is shown that ANNs can be applied successfully to modeling and forecasting MWG on a national scale, and performs well for countries with highly diversified levels of economic development, industrial structure, productivity and output.
Journal ArticleDOI
Preparation and characterization of pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
Nedeljko Milosavljević,Nikola Milašinović,Ivanka G. Popović,Jovanka M. Filipović,Melina Kalagasidis Krušić +4 more
TL;DR: In this paper, a pH-sensitive hydrogel based on chitosan, itaconic acid and methacrylic acid was synthesized in two steps and the results showed that the gels demonstrate substantial change in buffer absorbency with change of pH, low for acid buffers and the higher for pH values above 6 where the swelling is considerably slow.
