From smartphones to the operating interfaces of ticket machines and cash dispensers, touchscreens require transparent electrodes in order to recognize finger pressure. The glass surfaces of these devices are coated with a grid of barely visible gold or silver, the walls of which are so thin they’re barely visible. Called nanowalls or nanowires, these new type of transparent electrodes offer great potential as transparent electrodes in display and solar cell applications.
Among the many types of nanomaterials, quantum dots (QDs) are like no other. At dimensions typically below 10 nanometers (nm), these nanocrystalline semiconductors, metals and magnetic materials are 20,000 times smaller than a human hair and resemble the tiny semiconductors used in consumer electronics.
Researchers in the field of nanotechnology have discovered new tools that could change how cancers and brain diseases, such as dementia and Parkinson’s disease are treated in the future.
Among the numerous categories in the evolving field of newly synthesized nanomaterials, carbon nanotubes (CNTs) are perhaps among the most dynamic and undergoing the most rapid pace of development. The past 15 years have witnessed relentless growth in the research, development, and technological understanding of these remarkable materials.
