Nanoengineered Materials - Nanotechnology

What are Nanoengineered Materials?

Nanoengineered materials are materials that have been designed and manipulated at the nanoscale (1 to 100 nanometers) to exhibit specific properties. These materials leverage the unique physical, chemical, and mechanical properties that arise at the nanoscale to create advanced functionalities not possible at larger scales.

How are Nanoengineered Materials Created?

The creation of nanoengineered materials involves various techniques such as bottom-up approaches (like self-assembly and chemical vapor deposition) and top-down approaches (like lithography and etching). Both approaches aim to precisely control the material's structure at the atomic or molecular level.
