The Periodic Table of Videos is a collection of more than 350 videos, and growing every week.
We love making them and are grateful to the audience who watch.
But the project takes time and resources - we can't do it without support.
Several organisations (and of course the University of Nottingham itself) have made the videos possible.
And now we have secured sponsorship from one of THE big names in chemistry - Sigma-Aldrich.
Anyone working in a chemistry lab would know the name Aldrich and its familiar logo on chemical containers.
Their support has secured the future of our videos for a couple more years at least.
Here's the page on which we thanks all our sponsors.
