School of Physics, Engineering and Technology Winter Webinar Series
Engineering at the nanoscale involves manipulating materials and building devices on an incredibly small scale—usually within 1 to 100 nanometers, which is 1000 times smaller than the diameter of a human hair. At this scale, materials exhibit unique properties not seen in their bulk counterparts, such as altered electrical conductivity, strength, flexibility, and reactivity. High Surface-to-Volume Ratio is one of the reasons to see such different properties. The small size of nanostructures provides a large surface area relative to their volume. This creates a high level of surface energy, which gives us opportunities to build devices with unique properties. Nanoscale engineering has opened the door to creating devices and systems that are not only small but also capable of unprecedented performance in fields like medicine, electronics, energy, and environmental protection. This includes development of very sensitive biosensors to measure small molecules like DNA and virus, building superconductor devices for quantum computing and creation of energy efficient solar cells.
