Single walled carbon nanotubes (SWNTs) have attracted immense research interest because of their remarkable physical and electronic properties. In particular, electronic devices fabricated using individual SWNT have shown outstanding device performance surpassing those of Si. However, for the widespread application of…
Uniaxial phase of the axial quadrupole spin-1 magnet in an external magnetic field is investigated. A case where the system includes single-ion anisotropy and anisotropic biquadratic exchange interaction the most general form, is considered. It is proved, that the molecular field approximation of the relative magnetiz…
Hydrothermal reactions of 5-(pyridin-2-yl-methyl)aminoisophthalic acid(H2paip) with Mn(OAc)2·4H2O and Cu(NO3)2·3H2O produced two 2D complexes, [Mn(paip)]n·nH2O(1) and [Cu(paip)(H2O)]n(2). In complex 1, paip serves as a μ4-bridge, and its two carboxylate groups in μ2,η2-bridging and chelating modes connect Mn(Ⅱ) into 1…
Spice essential oils and their constituents are powerful antimicrobials against\nfoodborne pathogens. However, their low sensory threshold and low aqueous solubility\nmake their application to fresh produce a challenge. Encapsulation within a\nbiocompatible material has the potential to mask sensory attributes and inc…
By measuring energy spectra of the electron emission from a sharp tungsten tip induced by few-cycle laser pulses, the laser-field dependence of the emission mechanism was investigated. In strong laser fields, we confirm the appearance of laser-driven tunneling emission and find that it can be disentangled from the con…
Due to the increased use of the power electronic equipment, harmonics in the power system has increased to a greater extent. These harmonics results a poor power quality causing a major effect on the customers. Shunt active filters (SHAF) are used for the mitigations of the current harmonics and to maintain constant D…
A new three-dimensional(3D) coordination polymer, [Cd(L)2H2O]n·5nH2O 1 with 4-[(3-pyridyl)methylamino]benzoate acid(HL), has been synthesized by slow evaporation solvent at room temperature, and structurally characterized by elemental analysis, IR spectrum, thermal analysis, fluorescence spectrum and single-crystal X-…
The work involves develops attended by a numerical execution of the eXtend Finite Element Method premises a measurement by the fracture process cracked so many cracked plates an application will be processed for the calculation of the stress intensity factor SIF. In the first we give in statically part the distributio…
Three polynuclear clusters, [Cu4L8](ClO4)4·4H2O (1), [Zn3L6(H2O)6](ClO4)6·6H2O (2), and [Mn3L6(CH3OH)6](ClO4)6·4.5H2O (3) (L = 4-(4-hydroxyphenyl)-1,2,4-triazole), obtained by the reactions of M(ClO4)2·6H2O with L have been isolated and structurally characterized. Complex 1 featured a tetranuclear Cu(I) structure. Bot…
Optical characterization of all types of displays is mandatory to quantify the different imperfections and compare the different technologies. Standard characterization is focused on luminance and color measurements of the light emitted by the displays. Viewing angle measurements devoted to the angular characterizatio…

In a planar liquid crystal sample sandwiched between a photosensitive and a reference plate instabilities occurred, when the cell was illuminated from the reference side. The instabilities were induced both by polarized white light source and monochromatic laser beams. Static and dynamic regimes were found; for laser…
The G(E) function method is a spectrometric method for the exposure dose estimation; this paper describes a method based on Monte Carlo method to determine the G(E) function of a 4″ × 4″ × 16″ NaI(Tl) detector. Simulated spectrums of various monoenergetic gamma rays in the region of 40 -3200 keV and the corresponding…
The homologous series of an alkoxyazobenzene-triphenylene system (CnTEsAz) in which six alkoxyazobenzenes are attached to triphenylene via propyleneester linkage were synthesized to study their mesomorphism. DSC and XRD measurements in addition to the optical texture observation clarified these homologues to be mesomo…
Two Cu(II)-complexes, {[Cu2(O2N-ipO)2(H2O)2]·(H2dpa)}n (1) and [Cu3(O2N-ipO)2(btb)]n (2) (O2N-ipO = deprotonated 5-NO2-2-hydroxylisophthalic acid, H2dpa = protonated dipyridin-4-ylamine and btb = 1,3-bis(1,2,4-triazol-l-yl)butane), were synthesized from an in situ generated 5-NO2-2-hydroxylisophthalic acid and charact…
Prerequisite for virtually all nematic field-effects on which liquid crystal displays (LCDs) are based is stable, uniaxial surface alignment with defined bias tilt angle between the long liquid crystal (LC) axes and their display boundaries. Since the invention of the TN-LCD [Citation1] in 1970 until recently this was…
Based on our invention of an energy‐efficient Czochalski crystal growth furnace, a 2D‐axisymmetric numerical simulation model of LiNbO3 crystal growth is developed. The heat transfer, melt and gas flow, radiation and the interface deflection have been examined. Heat losses in the furnace and the insulator, as well as…
Various fabrication methods of photomobile polymer materials containing photochromic moieties have been developed to improve their photoresponsive and mechanical properties. Here, we newly prepared photomobile polymer materials with interpenetrating polymer network (IPN) structures. The IPN films, which are composed o…
Passive and active polarization elements were created by surface and bulk photo-alignment of LCs, reactive LCs, photo-sensitive LCP and photo-curable monomer/LC composites.
