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 ...
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 ...
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 ...
THERMOTROPIC, REFRACTING AND THERMO-OPTICAL PROPERTIES IN THREE HOMOLOGS OF 4-N-ALKYL-4 '-CYANOBIPHENYLS
(Lithuanian Physical Soc, 2015)
Investigations of temperature behaviour of the mean refractive index n, ordinary n(o) and extraordinary n(e) refractive indices, and birefringence Delta n have been carried out for three homologues of 4-n-alkyl-4'-cyanobiphenyls ...
4,4- bipiridin ve 2-amino-1,4-benzendikarboksilik asit tabanlı yeni bileşiğin sentezlenmesi ve hidrojen bağlı 3D polimerik yapısı
(2018)
Yeni bileşik, [NH2-BDC][4,4-bpy], (NH2-BDC = 2-amino-1,4-benzen dikarboksilik asit, 4,4-bipy = 4,4-bipiridin) sentezlendi ve tek kristal X-ışını kırınım metodu ile karakterize edildi. Kristalin yapısal analizi bileşiğin ...
A new simulation model for inhomogeneous Au/n-GaN structure
(Pleiades Publishing Inc, 2016)
The larger the device area, the more difficult to carry on homogeneity during the fabrication and following treatments. Structural inhomogeneity may indicate themselves in variations in local electronic device parameters. ...
Magnetic and Magnetocaloric Properties of High-Energy Ball-Milled Nanocrystalline CeMn2Ge2 Compound
(Springer, 2016)
CeMn2Ge2 nanopowders have been obtained by high-energy ball milling for 5 and 10 hours from bulk compound to investigate the effect of milling time on magnetic and magnetocaloric properties. CeMn2Ge2 nanopowders have been ...
Peculiarities of thermo-morphologic and thermotropic transformations of heterophase regions: nematic <-> isotropic phase transition in 4-n-Alkyl-4 '-cyanobiphenyl mesogens
(Natl Inst Optoelectronics, 2019)
Important peculiarity of phase transitions in liquid crystalline materials is availability of the heterophase regions, in which low temperature and high temperature phases simultaneously take place. In this work, peculiarities ...
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 ...
High-diffraction-efficiency Fresnel lens based on annealed blue-phase liquid crystal-polymer composite
(Taylor & Francis Ltd, 2019)
We demonstrated a relatively simple and effective method to fabricate a periodically isolated polymer wall of blue-phase liquid crystal Fresnel lens (BPLCFL) by employing a single-masking process of the ultraviolet (UV) ...
