Bidisperse Magnetic Particles Coated with Gelatin and ...
The magnetorheology and dispersion stability of bidisperse magnetic particles (BMP)-based magnetorheological (MR) fluids were improved by applying a novel functional coating composed of gelatin and graphite oxide (GO) to the surfaces of the micron-sized carbonyl iron (CI) and nanoparticles Fe3O4. Gelatin acted as a grafting agent to reduce the aggregation and sedimentation of CI particles …
Carbon encapsulated nanoscale iron/iron-carbide/graphite ...
Synergetic microwave absorption in carbon globules embedded with nanoscale iron/iron-carbide graphite (FeC) particles via dielectric, magnetic and Ohmic losses is emphasized in this work. The electromagnetic interference (EMI) shielding properties of the FeC nanoparticles dispersed …
Graphite - Sympatec
The final particle size of the graphite required for further processing or direct application is achieved using various grinding processes The size, shape and size distribution of the particles is ultimately determined by the functional properties of the graphite and the quality of the final products. Traditional screening analysis and microscopy are often still used to analyse the particle size and particle …
Kontaktwerkstoffe - DODUCO - Produkte & Lösungen
Because of the graphite particles dispersed in the silver matrix, Ag/C contact parts cannot be welded or brazed directly to substrates. Therefore a graphite-free bottom layer is necessary for attachment. This …
