About this collection
National Nanotechnology Day is an annual celebration in the US featuring a series of community-led events and activities on or around October 9 to help raise awareness of nanotechnology, how it is currently used in products that enrich our daily lives, and the challenges and opportunities it holds for the future. This date, 10/9, pays homage to the nanometer scale, 10–9 meters. More information is available here: https://www.nano.gov/nationalnanotechnologyday
This year we are celebrating nanotechnology’s achievements over the past 20 years around the theme: "Enabling the Nanotechnology Revolution.” This phrase is inspired by the vision statement for the National Nanotechnology Initiative which is to enable “a future in which the ability to understand and control matter at the nanoscale leads to ongoing revolutions in technology and industry that benefit society."
To celebrate we have put together a series of top articles by US researchers published recently across the Nanoscale journal family. We hope that you enjoy reading them!
