Nanomaterials exhibit unique properties at the nanoscale level compared to their macroscale counterparts. They can be synthesized into various shapes and structures, including nanoflowers, nanotrees, nanobouquets, nanocups, nanorings, nanosunflowers, and nanottedybears. These nanomaterials are characterized using techniques like scanning electron microscopy and x-ray diffraction methods to understand their structure, composition, and properties. Their small size leads to increased surface area and novel optical, magnetic, and electrical behavior with applications in fields such as catalysis, electronics, and optics.
