“Our recently developed magnetic force microscopy for simultaneous imaging of perpendicular and in-plane magnetic field gradients was applied to polycrystalline La0.7Sr0.3MnO3 granular films with in-plane magnetization. The present method clearly imaged the gradient of the perpendicular and the in-plane magnetic

field from the boundary phase, which behaved as a magnetic double layer with two separate planes of magnetic charges. Especially after magnetizing the film in one direction, the perpendicular and in-plane magnetic field gradients of a magnetic double layer with opposite-sign magnetic charges were clearly observed by this method. Calculated magnetic field gradients are consistent with those of the magnetic force microscopy images. The present method seems to be effective in evaluating the magnetic isolation

between neighboring magnetic grains having the component of in-plane magnetization. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3561151]“
“A novel polymeric flame retardant (FR) with phosphorous-nitrogen pendent groups (PVP-P-DCA) was synthesized by polyvinyl alcohol (PVA), phosphoric acid, and dicyandiamide (DCA). Its structure this website was characterized by FTIR, H-1, C-13, P-31 NMR, elemental analysis and TG. Poly(ethylene terephthalate) (PET)/cotton blends (T/C) was treated via pad-dry-cure process with PVP-P-DCA. The surface of FR-T/C was characterized by FTIR and SEM. The fabric performance was examined by whiteness and tensile property. The fire behavior was performed by limited oxygen index (LOI), vertical burning test, cone calorimetry test. The durability effect, thermal stability, and flame retardancy mechanism of the treated T/C were investigated by TGA, FTIR,

and SEM. The results show that PVP-P-DCA is not only an effective FR but also a good char-forming agent for the T/C. (c) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 122: 342-353, 2011″
“Long-chain alkanoic acids usually form close-packed monolayer films with alkyl chains highly oriented on substrates. Previous studies HDAC 抑制�?review have reported the adsorption of stearic acid on gold, aluminum, copper, silver, and aluminum oxide. However, there are no reports of stearic acid adsorption on magnetic metals. In this work, the characterization of stearic acid adsorbed on Ni(111) surface has been studied experimentally and with first-principles calculation. The results suggest that the stearic acid is chemically adsorbed on the Ni(111) surface via a bidentate interaction with a distance of about 1.8 angstrom. Besides this, we have also obtained results for the charge transfer and magnetic proximity effect. (C) 2011 American Institute of Physics. [doi:10.1063/1.
