The Crystal Structure of Micro- and Nanopowders of ZnS Studied by EPR of Mn2+ and XRD

The crystal structure of micro- and nanopowders of ZnS doped with different impurities was analyzed by the electron paramagnetic resonance (EPR) of Mn2+ and XRD methods. The powders of ZnS:Cu, ZnS:Mn, ZnS:Co, and ZnS:Eu with the particle sizes of 5-7 μm, 50-200 nm, 7-10 μm, and 5-7 nm, respectively, were studied. Manganese was incorporated in the crystal lattice of all the samples as uncontroll...

EPR and Structural Characterization of Water-Soluble Mn2+-Doped Si Nanoparticles

Water-soluble poly(allylamine) Mn2+-doped Si (SiMn) nanoparticles (NPs) were prepared and show promise for biologically related applications. The nanoparticles show both strong photoluminescence and good magnetic resonance contrast imaging. The morphology and average diameter were obtained through transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM...

Lyman spectrum of holes bound to substitutional 3d transition metal ions in a III-V host: GaAs(Mn2+, Co2+, or Cu2+), GaP(Mn2+), and InP(Mn2+)

Ülkemizdeki Trafik Kazalarının Zamansal Değişimlerinin İncelenmesi

There is an imperative need to understand how, where and when traffic accidents occur in order to develop appropriate accident reduction strategies. An improved understanding of the location, time and reasons for traffic accidents makes a significant contribution to preventing them. Traffic accident occurrences have been extensively studied from different spatial and temporal points of view usi...

EPR spectroscopic analysis of TAR RNA-metal ion interactions.

Metal ion-induced changes in HIV-1 TAR RNA internal dynamics were determined by the changes in EPR spectral width for TAR RNAs containing spin-labeled nucleotides (U23, U25, U38, and U40). This gave a dynamic signature for each of 10 metal ions studied, which fell into one of three distinct groups. While Li(+) and K(+) had little effect on TAR RNA internal dynamics, Na(+) unexpectedly had a dyn...
