Assessment of Accumulation and Potential Health Risk of Cr, Mn, Fe, Cu, and Zn in Fish from North-Eastern Mediterranean Sea
Heavy metal accumulation in aquatic organisms has been an important issue due to environmental pollution resulting from anthropogenic activities. In this study, Cr, Mn, Fe, Cu, and Zn in the selected fish species (Mullus barbatus, Solea solea, and Siganus rivulatus) from three consecutive bays (İskenderun, Mersin, and Antalya from North-Eastern Mediterranean Sea) were considered to provide some...

متن کاملMixed valency in polynuclear Mn/Mn, Mn/Mn and Mn/Mn/Mn clusters: a foundation for high-spin molecules and single-molecule magnets
Mixed-valent Mn/O dinuclear and polynuclear molecular compounds containing Mn are almost without exception trapped valence. Large differences between the strengths of the exchange interactions within MnMn, MnMn and MnMn pairs lead to situations where MnMn interactions, the strongest of the three mentioned and antiferromagnetic in nature, dominate the intramolecular spin alignments in trinuclear...
متن کاملClustering of Mn in (Ga,Mn)As
Clustering of (Ga,Mn)As is studied with the supercell density-functional calculations using the projector augmentedwave method. We find large binding energies for a single substitutional Mn atom to existing dimers and trimers giving rise to trimer and tetramer formation. For larger clusters this binding energy drops. In all cases studied, ferromagnetic alignment is found to be energetically mor...
متن کاملMn interstitial diffusion in (ga,mn)as.
We present a combined theoretical and experimental study of the ferromagnetic semiconductor (Ga,Mn)As which explains the remarkably large changes observed on low-temperature annealing. Careful control of the annealing conditions allows us to obtain samples with ferromagnetic transition temperatures up to 159 K. Ab initio calculations, in situ Auger spectroscopy, and resistivity measurements dur...
