Polypyrrole/montmorillonite (PPy/MMT) particles were synthesized using an oxidative polymerization method. Then the particles were added into polymethyl methacrylate (PMMA) as additives to prepare PPy/MMT/PMMA composite. The structures and properties of the composite were characterized by FT-IR, TGA, X-ray diffraction…
The longitudinal and transversal distribution of the self-balancing component оf elastic stresses in the rolled strip was analyzed as well as the amplitude attenuation coefficient. The results of this analysis are used for a design of new rolled strips flatness control methods.
The effect of both the process-induced defects and the dopant on the time-dependent-dielectric breakdown in Ta2O5 stacks is discussed. The breakdown degradation is analyzed in terms of specific properties of high-k stacks which make their dielectric breakdown mechanism completely different from that of classical SiO2.…
We study the time- and spectrally-resolved exciton dynamics of a few-layer molybdenum disulfide using ultrafast optical pump-probe spectroscopy. We find that the carrier induced broadening significantly influence on the band-edge transmission spectra even with small carrier densities.
Nanocrystalline materials have received much attention as advanced engineering materials with improved physical and mechanical properties. Attention has been directed to the application of nanomaterials as they possess high strength, high hardness and excellent ductility and toughness. A one-step synthesis and consoli…

Since smSERS (single molecule Surface-Enhanced Raman Scattering) was independently reported by S. Nie group and K. Kneipp group in 1997 [1][2], tremendous amount of interest has been shown to this field because Raman spectroscopy can provide molecular fingerprint together with multiplexing capability in bioassay. Rega…
The analysis of polymeric films is presented in article with flying inhibitors of corrosion, feature of packing and preparation for storage molybdenum, the tasks demanding the decision during carrying out a complex of laboratory and natural researches.
In this study Eupatorium adenophorum was evaluated as potential raw materials for Water-Absorbent Composite (WAC) synthesized with acrylic acid (AA) and acrylamide (AM) in aqueous medium. Factors, such as weight ratio of AA/AM to dry powdered Eupatorium adenophorum (DPEA), the amount of initiator and cross-linker, neu…
Exothermic reactions that undergo uncontrolled self-heating as a result of loss of cooling lead to a thermal runaway. Such reactions can present a serious hazard in the petrochemical (e.g. polymerisation processes) and chemical industries. They can reach excessively high rates of temperature increase, either due to pr…
Currently, most of integrated transformers are fabricated without magnetic core. In order to reduce the size and to improve their performances, we were interested in the study of integrated transformers based of thin ferrite films. Interleaved and Face to Face structures were simulated using the Ansoft HFSS simulator…
Abstract: Background: While promising, cationic lipid-mediated gene delivery can still benefit from improvements in lipid design and lipid-DNA (lipoplex) formulation. The putative mechanism of cellular lipoplex uptake is believed to occur by endocytosis, where the key influential factors are lipoplex size and morpholo…

Co-rich Co-Pt films have been electrodeposited on Si (100) substrates with a 30 nm thick Cr buffer and a 10 nm Au conducting layer. Films have been deposited on different days after preparing the electrolyte, at current density of 28 mA/cm2, keeping all other deposition parameters constant. It has been observed from p…

We demonstrate the chemical synthesis of Co doped SnO nanoparticle and subsequently the X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and ultraviolet spectroscopy were employed to characterize the phase, particle size, composition and bandgap of the particles. Well c…
The stimulated emission threshold of SPPs can be reduced by an order of magnitude if the operation range is changed from visible to near-IR and metamaterial substrates are used instead of silver films.
(N, S)-codoped TiO2 nanotubes were fabricated by hydrothermally treating (N, S)-codoped TiO2 nanoparticles in a NaOH solution at 110°C for 20 h. The (N, S)-codoped TiO2 nanoparticles were synthesised by a solvothermal process with precursor solution containing titanium sulphate, thiourea, and dichloroethane. The (N, S…
R. F. sputtered ultrathin silver-silica heterostructures were studied by variable-angle spectroscopic ellipsometry and by its analogue working in total reflection mode. The last one enables an enhanced sensitivity to the interface plasmonic properties.
A novel S-doped Sr3SiO5: Eu2+ phosphor was synthesized employing high temperature solid-state reaction method under reductive atmosphere environment. The crystal structure and photoluminescence properties of the phosphor, and the effect of S2- doping concentration on the photoluminescence intensity of Eu2+ was studied…
