nanoscience. Flashcards
how many atoms do nanoparticles contain?
only a few hundred.
nanoparticles can combine to form structures called what?
nanostructures.
what can be done to nanoparticles and what does it mean for it?
manipulated.
materials can developed that have new and specific properties.
in nanoparticles where can the atoms be placed to to achieve the required properties or effects?
into exactly the right position so smaller quantities are needed.
example of where nanoparticles are used in and why?
sun cream.
better coverage so more effective protection from sun’s harmful ultraviolet rays.
what are the concerns around the usage of nanoparticle?
they are so small and could they get into and damage human cells or cause problems in the environment.
research into nanoparticles is leading the development of what?
new drug delivery systems.
synthetic skin for burn victims.
computers and technology.
catalysts for fuel cells.
stronger and lighter construction materials.
new cosmetics and deodorants.
fabrics that prevent the growth of bacteria.
