Nanotech Frontiers: Nanotech Holds Great Promise, But Also Poses Big Challenges
Every day, researchers take giant strides toward realizing the huge potential of nanotechnology. Their efforts have already resulted in strong, lightweight materials.
"Most of the research is focused on improving material properties or developing new materials," says Hrishikesh Bidwe, a technical analyst at Frost & Sullivan Inc. (San Antonio, TX). For instance, scientists have engineered composite materials that are a hundred times stronger than steel, yet weigh only one-sixth of its mass.
