Properties of Nanomaterials - Introduction to Nanotechnology

Explore the fascinating world of nanomaterials in this comprehensive 1-hour 13-minute presentation from the NACK Introduction to Nanotechnology Educators Workshop. Delve into the unique properties of materials at the nanoscale, including structural color, nanoparticles in medicine, and quantum dots. Examine the four forces of nature and their impact on nanomaterials, with a focus on intermolecular forces and gravity. Investigate superhydrophobicity, the lotus effect, and surface area to volume ratios in various applications. Learn about motion at the nanoscale, Reynolds numbers, and viscosity. Conclude with an exploration of quantum effects, tunneling, and their implications for computing and fabrication techniques in nanotechnology.
