Answer» Lightweighting of cars, trucks, airplanes, boats, and space craft could lead to significant fuel savings. Nano-bioengineering of enzymes is aiming to enable conversion of cellulose from wood chips, corn stalks, unfertilized perennial grasses, etc., into ethanol for fuel. Nanoparticles are used increasingly in catalysis to boost chemical reactions. Nano-engineered materials make superior household products such as environmental sensors, air purifiers, and filters; antibacterial cleansers; and specialized paints and sealing products, such a self-cleaning house paints that resist dirt and marks.

Answer»

Lightweighting of cars, trucks, airplanes, boats, and space craft could lead to significant fuel savings.

Nano-bioengineering of enzymes is aiming to enable conversion of cellulose from wood chips, corn stalks, unfertilized perennial grasses, etc., into ethanol for fuel.

Nanoparticles are used increasingly in catalysis to boost chemical reactions.

Nano-engineered materials make superior household products such as environmental sensors, air purifiers, and filters; antibacterial cleansers; and specialized paints and sealing products, such a self-cleaning house paints that resist dirt and marks.
