Under appropriate conditions, a cloud of several hundred atoms can behave like a single atom, virtually developing super-power. Upon excitation with an ultraviolet laser into highly excited states, the atoms start to interact with each other.
A research team has made two advances in multiferroic materials, including the ability to integrate them on a silicon chip, which will allow the development of new electronic memory devices. The researchers have already created prototypes of the devices and are in the process of testing them.
The Penn State Center for Nanoscale Science, a National Science Foundation Materials Research Science and Engineering Center (MRSEC), has been awarded a six-year, $15 million grant to continue its research and education program in the development and application of nanoscale materials.
Silicene is the thinnest form of silicon. It is metallic, has graphene-like mobile carriers and can behave like a semiconductor. The material could lead to even smaller electronics but challenges remain.
Scientists are learning how the properties of water molecules on the surface of metal oxides can be used to better control these minerals and use them to make products such as more efficient semiconductors for organic light emitting diodes and solar cells, safer vehicle glass in fog and frost, and more environmentally friendly chemical sensors for industrial applications.
Scientists have made important steps toward understanding how dynein - a 'molecular motor' - walks along tube-like structures in the cell to move cellular cargo from the outer structures toward the cell body of neurons.
