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 ...
A comparison of the magnetism of cobalt-, manganese-, and nickel-ferrite nanoparticles
(Iop Publishing Ltd, 2018)
The microstructure, composition and magnetism of CoFe2O4, MnFe2O4 and NiFe2O4 nanoparticles of comparable sizes (similar to 20 nm) and interparticle spacings (similar to 20 nm) have been characterized from 10 to 400 K. The ...
What do we need for the lithium-air batteries: A promoter or a catalyst?
(Pergamon-Elsevier Science Ltd, 2016)
LaSr-based perovskite materials are frequently studied as catalyst at the cathode of the lithium-air batteries (LAB). In this study, we compared Pb, Ba and Sr in the form of La0.65X0.35MnO3 (X = Pb, Ba, Sr) at the cathode ...
Enhancing the c-TiO2 based perovskite solar cell performance via modification by a serial of boronic acid derivative self-assembled monolayers
(Elsevier, 2017)
Morphological control of MAPbI(3) crystal growth is one of the most important factor to fabricate high efficient perovskite solar cells. Herein, different boronic acid derivative self-assemble monolayers were used for ...
A new method to simulate photovoltaic performance of crystalline silicon photovoltaic modules based on datasheet values
(Pergamon-Elsevier Science Ltd, 2017)
Determination of photovoltaic performance based on single diode model and various methods requires iterative techniques, additional mandatory information and users with a certain level of knowledge. Further, the most of ...
Synthesis, characterization and photoluminescence studies of new Cu(II) complex
(Taylor & Francis Ltd, 2017)
In the current work, a new coordination complex, [Cu(HL)(2)], 1 [H2L = 2-((E)-(2-hydroxypropylimino) methyl)-4-nitrophenol] was successfully synthesized and characterized by IR, UV-vis and photoluminescence spectroscopic ...
Shading effect on the energy rating of two identical PV systems on a building facade
(Pergamon-Elsevier Science Ltd, 2015)
The first BIPV system of Turkey was installed on the facade and two towers of the Staff's Block of Education Faculty building of Mugla Sitki Kocman University in February 2008. The PV systems cover 405 m(2) (60 tilted ...
A different approach to solar cell simulation
(Pergamon-Elsevier Science Ltd, 2015)
Zero barrier height inhomogeneity in the device is generally assumed to conform to Gaussian distribution in the literature. In this study, zero barrier height inhomogeneity has been adopted to obey random distribution. ...
Phase formation characteristics and magnetic properties of bulk Ni2MnGe Heusler alloy
(Elsevier Science Sa, 2015)
We have systemically studied the effects of annealing temperature and alloy composition on the structural and magnetic properties of bulk Ni2MnGe and Ni2.1Mn0.9Ge Heusler alloys. We have observed that both annealing ...
2-and 1-D coordination polymers of Dy(III) and Ho(III) with near infrared and visible luminescence by efficient charge-transfer antenna ligand
(Elsevier Science Bv, 2017)
Two new lanthanide-based coordination complexes, [Dy(2-stp).2(H2O)]n (1) and {[Ho(2-stp).3(H2O)]center dot(H2O)}(n) (2) [2-stp = 2-sulfoterephthalic acid] were synthesized by hydrothermal reaction and characterized by ...
