The structural phase transition in RAlO3 (R = La, Pr and Nd) perovskites has been investigated using density functional theory with generalized gradient approximated exchange-correlation. Ambient pressure rhombohedral structure (R3¯c) transforms to a cubic structure (Pm3m) under pressure and the estimated transition p…
We have determined refractive indices of rubrene crystals in the wavelength regions where their emissions were observed. For this purpose, we grew in a vapor phase the rubrene crystals having both horizontal and vertical pairs of parallel crystal facets. The facets functioned as optical resonators that produced interf…
The title compound dichloro tris(triphenyl phosphine oxide)cadmium(II) were grown by slow cooling method from aqueous solution. The title compound was synthesized and purified by repeated crystallization process. Grown crystals were characterized by X-ray diffraction and FTIR analysis. The range of optical transmissio…
In this work the magnetic properties (exchange parameters, magnetic moment of non-stoichiometric Ni–Mn–Ga Heusler alloys with structural disorder by the help of ab initio calculations have been performed. Theoretical composition dependences of the total magnetic moment are in qualitative agreement in qualitative agree…
In this contribution, the orientation adhesion and dendritic crystals of ZnO nanocrystallites were synthesized by the method of ultrasonic spray pyrolysis. The microstructure was characterized by X-ray diffraction (XRD) and Raman Spectroscopy, the morphological analyses were carried out by Scanning Electron Microscopy…
We prepared O/W emulsion composed of a synthetic perfume, n‐dodecane, protoporphyrin IX disodium salt (PpIX‐2Na), sodium dodecyl sulfate, and water and investigated oxidative decomposition of the synthetic perfume in the emulsion and change in the stability of the emulsion by singlet oxygen (1O2) generated by photosen…
The phenomena of appearance of thermo-emf at non-stationary heating in equiatomic titanium nickelide was examined. The peculiarities of kinetics of display of thermokinetic emf, also during thermocycling were determined. The possibility of generation of thermo-emf in amorphous-crystalline ribbon of Ti50Ni25Cu25 during…
High extinction coefficients and easily tunable spectral properties of π- conjugated donor-acceptor dyes are of superior advantage for the design of new metalfree organic sensitizers for applications in dye-sensitized solar cells. Ultrafast transient absorption spectroscopy on the femtosecond and nanosecond time scale…
The structure and conformational properties of star-shaped oligostyrenes containing fullerene C 60 as a branching center and short arms with lengths at the level of the persistent length or a segment of a polystyrene chain are studied by small-angle neutron scattering in deuterotoluene. The gyration radii of linear pr…
Here we show the realization of a stable room temperature electrically driven single-photon source based on a single NV centre in a diode structure. Remarkably the generation of electroluminescence follows a fundamentally different kinetics than photoluminescence. This suggests electroluminescence is generated by elec…
The migration of radionuclides (RN) in the environment is a topic of general interest, for its implications on public health, and it is an issue for the long-term safety studies of deep geological repositories (DGR) for high-level radioactive waste. The role played by colloids on RN migration is also of great concern.…
Thermoelectric materials are able to generate a voltage and current, when subjected to a gradient of temperature. A cost and time efficient production of thermoelectric units is the goal for future miniaturized thermoelectric generators based on thin films up to 200 μm. A comprehensive analysis of chemical and physica…
The existence of an indirect magnetoelectricity in a soft composite material prepared as a mixture of magnetite ferromagnetic nanoparticles (NPs) and the ferroelectric liquid crystal (FLC) Felix 015/100 was verified by using a SQUID-based magnetometer. It was observed that the orientation of nanoparticles is directly…
The Monte Carlo simulations of charged particle transport are used to investigate the effects of exposing ultra-thin layers of insulators (commonly used in integrated circuits) to beams of protons, alpha particles and heavy ions. Materials considered include silicon dioxide, aluminum nitride, alumina, and polycarbonat…
This chapter reviews the literature reported during 2012 on gold and silver coordination and organometallic chemistry with a focus on synthesis and unique structures, photophysical properties, biochemical studies, and homogeneous catalysis. Nanomaterials, surface chemistry, and heterogeneous catalysis are not discusse…
The study explores the convergence of the coupled-wave analysis as applied to some kinds of relief diffraction gratings in the optical and the near infrared range for certain wavelengths. It is shown that the dependence between the transmission and the number of coupled waves in case of TE-wave diffraction by metal na…
In this paper, we demonstrated direct formation of large area Cu(In,Ga)Se2 nanotip arrays (CIGS NTRs) by using one step Ar+ milling process without template. By controlling milling time and incident angles, the length of CIGS NTRs with adjustable tilting orientations can be precisely controlled. Formation criteria of…
Colloidal semiconductor quantum dots (QDs) and their bioconjugates are of great interest for bioanalysis and bioimaging. These brightly luminescent nanoparticles can be utilised as probes to light-...
A number of newly Ln-N bond valence parameters were quantitatively estimated, which allowed us to obtain all Ln-N bond lengths with different coordination numbers in metal organic complexes. Twenty linear correlations among the mean bond valence parameters of Ln-O, Ln-N, Ln-S, Ln-Cl and Ln-C bonds of metal organic com…
The ignition criterion, ignition energy and gain of DT-plasma of ICF-target in the presence of impurities of light atoms such as beryllium, carbon and lithium at their arbitrary concentration are found. It is shown that the most promising type of non-cryogenic solid thermonuclear fuel is DT-hydride of beryllium (BeDT)…
