Lightlike hypersurfaces of a semi-riemannian product manifold and quarter-symmetric nonmetric connections
(Hindawi Publishing Corporation, 2012)
We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical anti-invariant lightlike hypersurfaces. ...
The present status, distribution, demography, and diet of the Dahl’s Jird
(Instituto Internacional de Ecologia, 2022)
Meriones dahli (Shidlovsky, 1962) was previously accepted to be a subspecies of M. meridianus (Pallas, 1773). However, it was later suggested that they are geographically isolated from each other. Although hybridological ...
Novel Non-Metal Cation (NMC) Pentaborate Salts of Some Amino Acids
(Mdpi, 2019)
Non-metal cation (NMC) pentaborate structures, in which some amino acids (valine, leucine, isoleucine, and threonine) were used as cations, were synthesized. The structural characterization of molecules was carried out by ...
Novel mixed ligand coordination compounds of some rare earth metal cations containing acesulfamato/N,N-diethylnicotinamide
(Scientific Technical Research Council Turkey-Tubitak, 2021)
The mixed ligand coordination compounds containing acesulfamato and N,N-diethylnicotinamide biomolecules of some rare earth metal cations (Eu3+, Tb3+, Ho3+, Er3+ and Yb3+) were synthesized, and their structural properties ...
Synthesis of CeO2-based core/shell nanoparticles with high oxygen storage capacity
(Springer International Publishing Ag, 2017)
Ceria plays a key role in various applications including sensing and catalysis owing to its high oxygen storage capacity (OSC). The aim of this work is to prepare novel MO (x) /CeO2 (M: Zr, Ti, Cu) metal oxide systems with ...
Novel mixed ligand complexes of alkaline earth metals with coumarilic acid and nicotinamide
(Turkish Chemical Society, 2021)
Coordination compounds with mixed ligands were synthesized with 2A group (Mg2+, Ca2+, Ba2+, Sr2+) alkaline earth metal cations of coumarilic acid and nicotinamide ligands. Afterward, the structural properties of these new ...
Bazı metal organik kafes yapılı bileşiklerin hidrojen depolama performanslarının incelenmesi
(2013)
Hidrojenin bilinen depolama sistemlerinden farklı olarak depolama ortamlarında kimyasal olarak veya zayıf van der Waals etkileşimleriyle fiziksel olarak tutunabildiği bilinmektedir. Hidrojen, fiziksel adsorpsiyonla karbon ...
Investigation of the effects of Tm 3+ on the structural, microstructural, optical, and magnetic properties of Sr hexaferrites
(Elsevier B.V., 2019)
SrTm x Fe 12?x O 4 (0.00 ? x ? 0.10) hexaferrites (HFs) are produced successfully using a sol–gel approach. The structural, optical, and magnetic properties are investigated. The hexagonal phase is confirmed for all the ...
Magnetic Attributes of NiFe2O4 Nanoparticles: Influence of Dysprosium Ions (Dy3+) Substitution
(Mdpi, 2019)
This paper reports the influence of dysprosium ion (Dy3+) substitution on the structural and magnetic properties of NiDyxFe2-xO4 (0.0 <= x <= 0.1) nanoparticles (NPs) prepared using a hydrothermal method. The structure and ...
Effects of Ce-Dy rare earths co-doping on various features of Ni-Co spinel ferrite microspheres prepared via hydrothermal approach
(Elsevier, 2021)
The effects of Ce-Dy co-doping on the crystal structure, optical, dielectric, magnetic properties, and hyperfine interactions of Ni-Co spinel ferrite microspheres synthesized hydrothermally have been studied. A series of ...
