Method 4: Use Dry Ice. Primarily used as a cooling agent, dry ice can be used to get out small dents from your car. As long as you're wearing protective gloves, hold down a piece of dry ice on the dent and rub it around until you hear your dent pop back into place.
This effect was maintained for 1 to 2 months. You could say that nano gold, which is far more bioavailable than even a gold colloid, is a blessing for the brain. Also, nano gold is a very powerful anti-inflammatory agent. Gold has long been used in the treatment of rheumatoid arthritis. However, in traditional treatments, gold compounds are used which are toxic and produce a lot of side effects.
Boron nitride has potential use in nanotechnology. Nanotubes of BN can be produced that have a structure similar to that of carbon nanotubes, i.e. graphene (or BN) sheets rolled on themselves, but the properties are very different.oron nitride has been produced in amorphous (a-BN) and crystalline forms. The most stable crystalline form is the hexagonal one, also called h-BN, Î±-BN, or g-BN (graphitic BN). Hexagonal boron nitride (point group = D 6h; space group = P6 3 /mmc) has a layered structure similar to graphite.
