Data supporting the hierarchically activated deformation mechanisms to form ultra-fine grain microstructure in carbon containing FeMnCoCr twinning induced plasticity high entropy alloy
Supporting data for describing the associated mechanisms in microstructure evolution and grain refinement of a carbon-doped FeMnCoCr TWIP high-entropy alloy (HEA) during thermomechanical processing. Microstructural characterization before and after deformation was performed using scanning electron microscope (SEM) outfitted with EBSD detector and transmission electron microscopy (TEM) were used for microstructure observation and investigation of nanostructure evolution during deformation. Inverse pole figure (IPF) map, grain boundary map and kernel average misorientation map (KAM) were used for systematic analysis of nanostructural evolution and deformed heterostructure consisting of hierarchical mechanical twinning, shear-banding, microbanding and formation of strain-induced boundaries (SIBs).THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

IRON OXIDE NANOPARTICLES IN DRUG DELIVERY SYSTEMS
The geometry and electronic structure of iron oxide Fe 3 O 4 with di-glucose and pentapeptide CREKA complex compound have been studied by the semiempirical molecular mechanics MM + and quantum chemistry Đ Đś3 methods. The geometrical and energy parameters, characterizing the low energy states of the complex, were calculated using the HyperChem 8.03 program. A synthetic macromolecule, aminodextran-coated iron oxide nanoparticles conjugated with CREKA peptide, was then synthesized as a nanocarrier, which was detectable using magnetic resonance imaging. The synthesis process began with a two-step reaction that attached a high density of amino groups to a dextran backbone. The aminodextran-coated iron oxide nanoparticles thus synthesized were characterized using Fourier transform infrared spectroscopy. Also, the morphology of this synthetic macromolecule was studied by scanning electron microscopy
