The magnetic shielding tensors of protons of water in barium chlorate monohydrate are investigated at room temperature by means of solid-state NMR spectroscopy, both for static powders and under magic-angle spinning conditions, using oneand two-dimensional techniques. First-principles DFT calculations based on a periodic planewave pseudopotential formalism for a static periodic system provide s...

The superiority of deformable human fingertips as compared to hard robot gripper fingers for grasping and manipulation has lead to a number of investigations with robot hands employing elastomers or materials such as fluids or powders beneath a membrane at the fingertips. When using such materials, it is important to account for their properties during manipulation. The rigid-body rolling kinem...

A method has been developed to study the properties of composite SMC materials based on high-purity iron powders, lowest carbon content materials, for example, ABC100.30 powder, have higher values magnetic parameters and minimal losses. The structure morphology surface obtained were studied. results influence various insulating coatings obtained, with titanium oxide had better characteristics. ...

We report a novel purification system for 6 His-tagged proteins by magnetic affinity separation. We have developed superparamagnetic Fe3O4@SiO core-shell particles with immobilized surface iminodiacetate groups to chelate with Ni. This Ni magnetic silica nanoparticle has been shown as an efficient carrier, binder and anchor to obtain his-tagged protein directly from total cell lysate. The struc...

We have studied the effect of Fe substitution on structural and magnetic properties of La2/3Ca1/3Mn1-xFexO3 (LCMFO; x=0, 5 and 10%) manganites. The powders were prepared by the solid state reaction method, and the final products were characterized by X-Ray Diffraction (XRD), Mössbauer Spectrometry and Magnetic Measurements. Only one single phase corresponding to the manganite phase was detected...

The viability of dilute magnetic semiconductors in applications is linked to the strength of the magnetic couplings, and room temperature operation is still elusive in standard inorganic systems. Molecular semiconductors are emerging as an alternative due to their long spin-relaxation times and ease of processing, but, with the notable exception of vanadium-tetracyanoethylene, magnetic transiti...
