applications of nanoscience Flashcards
can nanoparticles be used in sun cream?
yes
what are the positives and negatives of using nanoparticles?
Large surface area to volume ratio makes them effective catalysts.
So small they can enter the skin and therefore the bloodstream.
Nanoparticles in sun creams can be absorbed deeper into the skin.
Large surface can make them too reactive and explosive in some situations.
what are some uses of nanoparticles?
Nanoparticles are now being used in the manufacture of scratchproof eyeglasses, crack- resistant paints, anti-graffiti coatings for walls, transparent sunscreens, stain-repellent fabrics, self-cleaning windows and ceramic coatings for solar cells.
why can nanoparticles have new applications?
Nanoparticles and their Applications. … The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive to some other molecules.
why should nanotechnology research continue?
Why is nanotechnology important? Nanotechnology improves existing industrial processes, materials and applications by scaling them down to the nanoscale in order to ultimately fully exploit the unique quantum and surface phenomena that matter exhibits at the nanoscale.
