Mechanical Applications of nanomaterials

Today we will discuss the mechanical applications of nanomaterials.

1.)    Tougher and Harder Cutting Tools. a) Cutting tools made of nanomaterials, such as tungsten carbide, tatalum carbide, and titanium carbide, are much harder, much more wear-resistant, erosion-resistant, and last longer than their conventional (large grained) counterparts.

b)      For the miniaturization of microelectronics circuits, the industry needs micro drills (drill bits with diameter less than the thickness of an average human hair or 100 um) with enhanced edge retention and far better wear resistance. As nano-crystalline carbides are much stronger, harder, and wear-resistant, they are currently being used in these micro drills. Continue reading “Mechanical Applications of nanomaterials”

Electrical applications of nanomaterials

Last time I have discussed the magnetic and medicinal applications of nanomaterials. Today to extend it further I will discuss the electrical properties of nanomaterials or nanoparticles.

Electrical properties of nanomaterials:

1.)    High Energy Density Batteries. As we all know that conventional and rechargeable batteries are used in almost all applications that require electric power. The energy density or storage capacity of these batteries is quite low requiring frequent recharging. Nanocrystalline materials are good materials for separator plates in batteries because they can hold considerably more energy than conventional ones. Nickel-metal hydride batteries made of nanocrystalline nickel and metal hydrides are envisioned to require far less frequent recharging and to last much longer.
