In order to produce tiny electronic memories or sensors in future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists have now demonstrated that this is possible at room temperature.
With the help of these quantum dots, researchers can use super-resolution technology to break the optical diffraction limit and fill the gap between the electron microscope (about 1 nm) and the ordinary visible optical microscope (200-250 nm).
Scientists have created a new type of conducting polymer containing both linear and ring elements. The new polymers have very different electronic properties than scientists would expect if the polymers simply added the contributions from each linear and ring-shaped component.
Researchers have shown how the structure of the MOF, and its interactions with the guest molecules, can produce a signal. With this understanding, researchers can design MOFs to be sensor materials for many important applications. These findings could lead to simpler ways to detect chemicals, including explosives.
Sending tiny droplets to a tumor and having them vaporized using focused ultrasound: it could be a new way of tracing a tumor or deliver drugs locally.
