TL;DR: In this article, the authors have studied nickel classical catalysts supported on Al2O3, SiO2 and Nb2O5 oxides, using simple (SIM) or EDTA-double impregnation (DIM) methods.
Abstract: We have studied nickel classical catalysts supported on Al2O3, SiO2 and Nb2O5 oxides, using simple (SIM) or EDTA-double impregnation (DIM) methods. Non-classical catalysts were obtained by pretreatment of the SIM or DIM nickel precursors in aqueous hydrazine at 353 K. The catalysts were characterized by H2-adsorption, H2-TPR, isopropanol decomposition and FTIR measurements. They have been tested in the gas phase hydrogenation of benzene. The results obtained show that the support surface acidity order was: SiO2

TL;DR: In this article, a series of bulk-size magnetic/insulating nanostructured composite soft magnetic materials with significantly reduced core loss and its manufacturing technology is presented, consisting of a magnetic component, which contains one or more magnetic components, and an insulating component.
Abstract: A series of bulk-size magnetic/insulating nanostructured composite soft magnetic materials with significantly reduced core loss and its manufacturing technology. This insulator coated magnetic nanostructured composite is comprises a magnetic constituent, which contains one or more magnetic components, and an insulating constituent. The magnetic constituent is nanometer scale particles (1-100 nm) coated by a thin-layered insulating phase (continuous phase). While the intergrain interaction between the immediate neighboring magnetic nanoparticles separated by the insulating phase (or coupled nanoparticles) provide the desired soft magnetic properties, the insulating material provides the much demanded high resistivity which significantly reduces the eddy current loss. The resulting material is a high performance magnetic nanostructured composite with reduced core loss.

TL;DR: In this article, a solution reduction process was used to synthesize Ni nanoparticles with different mean diameters of 15-83nm, which can be controlled by varying the concentration of NiCl 2 ·6H 2 O and synthesis temperature.

TL;DR: A precursor tape casting method is one in which chemical precursors are converted into a final chemical phase from green tapes to products as mentioned in this paper, where lower annealing temperatures instead of high temperature sintering allow the formation of grains of about 1 to about 100 nanometers.
Abstract: A precursor tape casting method is one in which chemical precursors are converted into a final chemical phase from green tapes to products. Because chemical precursors are employed rather than the final powder materials, sintering is not required to form the material. Lower annealing temperatures instead of high temperature sintering allow the formation of grains of about 1 to about 100 nanometers in the final material. In addition, when the final material is a magnetic/insulator composite, improved magnetic properties may be obtained.
