Giant electric field (E-field) tuning of the magnetic anisotropy, ferromagnetic resonance field, coercive field and anisotropic magnetoresistance PXD101 solubility dmso were demonstrated through strain mediated ME coupling in 10 nm thick Ni80Fe20/PZN-PT

multiferroic heterostructures. E-field dynamic modulation of magnetoresistance was also displayed. These provide great opportunities for electrostatic tunable MR devices. (C) 2011 American Institute of Physics. [doi:10.1063/1.3561771]“
“A novel application, utilizing polyacrylamide-g-carboxymethyl cellulose (CMC-g-PAM) in concentrating dilute solutions of Bovine serum albumin (BSA), was investigated. The grafting reaction parameters were investigated and the hydrogel smartness was verified. FTIR proved that the grafting reaction occurred between the hydroxyl group located in anhydroglucose C(2) position of CMC and the pi-bond of PAM and SEM confirmed a changed morphology to a fibrillar structure. The pH sensitivity was proved; as the grafted polymer attained its maximum swelling at pH 7.2 while the minimum swelling was observed under acidic conditions (pH 1-3). The rate of water uptake in the grafted polymer hydrogel was higher than that

of the homopolymer hydrogel and the swelling behaviors of both hydrogels obeyed second-order kinetics. The tested hydrogel showed a high potency towards concentrating BSA solutions with a concentration factor of 1 to 4.5 times and recovery of 60-90%. The concentration factor increased linearly with increasing both the polymer concentration and the process time and decreased with the increase in the protein concentration. The grafted polymer this website had stable efficiency in the concentration process for Buparlisib cell line 20 cycles. The obtained results have recommended the employment of the prepared CMC-g-PAM hydrogel in the down stream protein concentration process in the industrial scale. (C) 2011 Wiley Periodicals, Inc.

“Single phase ErMexMn1-xO3 (Me = Cu, Fe; 0 <= x <= 0.1) samples were synthesized by the solid state reaction method. The differences between the doping

effects on the Raman spectra and on the structural, magnetic, and thermal properties of the two systems have been systematically investigated. In the ErCuxMn1-xO3 system, lattice parameter a increases with doping, while lattice parameter c decreases. It is more complicated in the ErFexMn1-xO3 system, where lattice parameter a decreases with doping, while lattice parameter c is enhanced after an initial slight decrease. Raman spectra show that the phonon peaks of ErFexMn1-xO3 slightly shift to higher frequencies with doping, while those of ErFexMn1-xO3 apparently shift toward lower frequencies. Heat capacity data indicates that the Neel temperature of ErMnO3 is reduced to 61 K for ErCu0.1Mn0.9O3 by Cu doping, whereas it is slightly enhanced to 79 K for ErFe0.1Mn0.9O3 through Fe doping.
