Working with atomic-scale particles known as quantum dots, a Missouri University of Science and Technology biologist hopes to develop a new and better way to deliver and monitor proteins, medicine, DNA and other molecules at the cellular level.
The RUSNANO's Supervisory Council has approved the corporation's participation in a project that would found a high-tech enterprise manufacturing gallium-arsenide substrates, chips, and optical components based on vertically emitting lasers.
A small green beetle may have some interesting lessons to teach scientists about optics and liquid crystals - complex mechanisms the insect uses to create a shell so strikingly beautiful that for centuries it was used in jewelry.
Inspired by the work of 18th Century botanist Karl Linne, who assembled a literal circadian clock composed of flower species that open and close their petals at specific times of day, Japanese scientists recently set about constructing an analogous 'body clock' for mammals.
Singapore precision equipment manufacturer Solves Innovative Technology Pte Ltd, together with A*STAR's Institute of Materials Research and Engineering and Data Storage Institute, has built a machine capable of producing nanometer-size components and in wafer-scale volumes, for a host of applications in consumer electronics such as hard disk media and optical storage media.
The films show atoms being added in a regular pattern at the growing tip of a nanotube, like bricks to a round tower, support the so-called theoretical screw-dislocation-like model of carbon nanotube growth.
