Caltech engineers focus on the nano to create strong, lightweight materials

The lightweight skeletons of organisms such as sea sponges display a strength that far exceeds that of manmade products constructed from similar materials. Scientists have long suspected that the difference has to do with the hierarchical architecture of the biological materials—the way the silica-based skeletons are built up from different structural elements, some of which …

Self-Assembled Memory 10 terabits per inch – 250 DVDs in Disk the Size of a Quarter

The sawtooth ridges formed by cutting and heating a sapphire crystal serves to guide the self-assembly of nanoscale elements into an ordered pattern over arbitrarily large surfaces. Researchers say the new, easy-to-implement technique may transform the data storage industry. The density achievable with the technology we’ve developed could potentially enable the contents of 250 DVDs …
