ABSTRACT
A simple online search finds numerous remarkable nanoscale materials that seem to be on the verge of path-breaking new applications. Illustrative examples include chitosan nanoparticles (which could transport medications to specific disease-targets in the body), nano-cellulose (which can produce exceptionally fine screens for testing purposes and turn ordinary wearing apparel into body armor), carbon nanotubes (which can increase energy storage
efficiency in batteries and could also help desalinize sea water), titanium dioxide (whose anti-biofouling properties could give ship hulls greater longevity and longer service between overhauls), nanoscale mineral zeolites (which can retard evaporation and thereby maintain scarce supplies of fresh water), nanostructured glass and tungsten (which give military ordnance greater armorpiercing capability), and nanoscale zero-valent iron (which can help remediate environmental hazards).
