Stanford has trial access until December 10, 2016 to Nano. It is only available on-campus (no off-campus access). 

Because this database is expensive, new funds will be needed before it can be licensed.  As a first step, I wanted to make you aware of this resource and get your input about its usefulness.  Please send feedback to graceb@stanford.edu by December 12th.    

"Published by Springer Nature, Nano is a unique source providing highly indexed and structured information related to nanomaterials & devices in over 200,000 curated profiles that provides access to easily searchable nanoscience data, synthesis methods and literature."
