A rapid synthesis of 2-substituted 1,2,3-triazole-1-oxide derivative starting from 4-(methyl)isonitrosoacetophenone and its Ni(II) complex: Characterization, DNA binding and cleavage properties
(Elsevier Science Bv, 2017)An efficient route, not including any metal salt as a catalyst, for the synthesis of a new 2-substituted 1,2,3- triazole-1-oxide is reported in this paper. The title compound has been synthesized via reacting 4-(methyl)i ... -
Rarely convergent sequences in topological spaces
(Academic Publication Council, 2020)In this work, by using rare sets, we introduce a new type of convergence in topological spaces, called rare convergence, which is weaker than ordinary convergence. After presenting some examples, we investigate the ... -
Rational (Pade) approximation for estimating the components of the partially-linear regression model
(Taylor & Francis Inc., 2021)This paper proposes a new smoothing technique based on rational function approximation using truncated total least squares (P - TTLS) and compares it with the widely used smoothing spline method, which has become a very ... -

Reflective light modulator based on epsilon-GaSe crystal
(Optical Soc Amer, 2002)We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an epsilon -GaSe crystal and operated at the 1.960-eV line of a He-Ne laser. We demonstrate that the ... -
Refractive and birefringent properties and order parameter of nematic liquid crystal at the direct and reverse nematic <-> isotropic liquid phase transition
(Natl Inst Optoelectronics, 2016)Temperature dependences of the refractive indices, birefringence and molecular polarizability in large temperature interval and especially in the region of the direct nematic mesophase - isotropic liquid (for the heating ... -
Refractive and birefringent properties of 4-alkyl-4 '-oxycyanobiphenyls at direct and reverse phase transitions
(Taylor & Francis Ltd, 2017)Studies of temperature behavior of the mean refractive index, ordinary and extraordinary refractive indices, and birefringence have been carried out for three nematogens. The thermo-morphologic properties of the biphasic ... -
Regimes of current transport mechanisms in CdS/CdTe solar cells
(Iop Publishing Ltd, 2019)Forward bias recombination (current transport) mechanisms have been evaluated for thin film solar cells and correlated to the in-gap trap levels present. Here CdTe/CdS devices were chosen as an archetypal example of a ... -
