The influence of the dielectric on the properties of dielectromagnetic soft magnetic composites. Investigations with silica and silica hybrid sol–gel derived model dielectric

A correlation of magnetic properties with material density for soft magnetic composite cores

“…e.g. (Apoena Castro and Landgraf, 2004, Pang et al, 2007, Sampaia da Silva and de Campos, 2012, Shokrollahi and Janghorban, 2006, Wei Ding et al, 2014. The effect results from an increased Fe content in volume of samples with the higher densities.…”

Ceramic / inorganic-organic nano-hybrid composites for thermally stable insulation of electrical wires. Part I: Composition and synthetic parameters

“…Nano-hybrids of this study are designed from organosilanes with various R groups and x values and tailored for achieving optimal balance between thermal stability and mechanical flexibility. Nano-hybrids derived from MTMS through sol-gel processing are initially investigated as these were previously proved as thermally stable coatings [18,19]. The methyl group attached to silicon through C-Si covalent bonding can withstand a temperature over 400°C, as shown by the thermal analysis results in Figure 2.…”

“…We previously utilised siliconcontaining nano-hybrids with organic moiety of methyl as thermally stable coatings for fabrication of soft magnetic composites (SMC) and found that existence of the organic moiety imparts excellent compacting properties to SMC because of low surface energy of the nano-hybrid coating. The methyl group is removed during the annealing stage of compacted SMC, leaving a highly thermal stable silica insulating coating [18]. This work is to extend the concept for electrical wire insulation with high temperature capability.…”

Novel Optical Device Materials - Molecular-Level Hybridization

“…[11][12][13][14][15][16][17] In optical device materials, organically modified silicate glasses/transparent polymers have been actively pursued to develop novel optical devices, such as lasers, optical switches, optical fibers, waveguides, laser amplifiers, optical displays, and data storage devices. [11][12][13][14][15][16][17] In addition, we can also control the porosity of those organically modified silica, polysilsesquioxanes, by inserting different molecules or sizes of organic spacers as shown the void space in Figure 3 (right); due to the insertion of organic spacers, the porosity of the resulting hybrid glass significantly increased. [18][19][20][21][22][23][24][25][26] The expanded pores allow us to dope semiconductor or metal particles without any significant mechanical cracks.…”
