Sigma-Aldrich First Official Sponsor of Open Notebook Science Challenge

Thanks to speedy action from Sandy Adam and William Sommer at Sigma-Aldrich we have our first official sponsor for the Open Notebook Science Challenge!

They are willing to donate compounds (aldehydes, carboxylic acids and amines) to schools in most parts of the world for them to do solubility measurements under ONS conditions.

Contact me if interested in more details.
