Boron nitride (BN) reinforced polymer nanocomposites have attracted a growing research interest in the microelectronic industry for their uniquely thermal conductive but electrical insulating properties.

To overcome the challenges in surface functionalization, in this study, hexagonal boron nitride (h-BN) nanoparticles were noncovalently modified with polydopamine in a solvent-free aqueous Cited by: Aluminum matrix composites reinforced with boron carbide are a kind of materials that are widely used because of high strength, low density, and improved tribological properties.

Metal matrix composites (MMCs) possess significantly improved properties including highspecific strength; specific modulus, damping capacity and good wear resistance compared to unreinforced alloys.

There has been an increasing interest in composites containing low density and low cost reinforcements. Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust.

Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate opes: α- β-rhombohedral, β-tetragonal (and more). composites made from graphite-fiber/epoxy and boron-fiber/aluminum with a few stra-tegically located titanium foil layers were adhesively bonded to form a combined metal and resin matrix fiber composite hybrid.

Laminates were made using various combinations of these composite Size: 1MB.

The MMC driveshaft is made of an aluminum matrix reinforced with boron carbide, allowing the critical speed of the driveshaft to be raised by reducing inertia.

The MMC driveshaft has become a common modification for racers, allowing the top speed to be increased far beyond the safe. The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s 2 2p 1.
