Liquid Crystals and Lighting up Gold(III)
Wednesday, 10 Mar 2021 7:30 pm

Liquid crystals are a distinct fourth state of matter and are commonly found around us in several diverse areas including technology (TV screens, computer screens and thermometers), soaps and natural systems such as cell membranes, but few people are aware of this delicate state.

I will introduce what liquid crystals are, where they meet organic light emitting diodes (OLEDs) and how my own work on

When three scientifically-minded Cirencester friends thought of forming a small group to enjoy talks on a range of scientific subjects, little could they have foreseen that twenty-one years later it would be flourishing with over 200 members.  Its name belies the wide area from which members come, stretching from Stroud in the West, northwards to Cheltenham and Malmesbury in the South. 

Each year the society holds a series of ten lectures on a varied selection of topics intended to appeal to a wide variety of interests and levels of scientific background.  Members include not only scientists, doctors and engineers but also many who have a general interest in science and technology.

Our friendly meetings are held at 7.30pm on the second Wednesday of each month, usually at the Royal Agricultural University.  The CSTS has moved to on-line streaming of its talks until face-to-face talks are again feasible.  Our Zoom ID is 912 0723 6181, and an invitation e-mail is sent to members regularly.  If you are not a member but wish to attend a lecture, please contact us at .  A contribution of £3 is requested from non-members, which is waived for students.  All are welcome.

 Students are admitted free. 

Exhibitions have been arranged in the past and visits are made regularly to places of scientific and technological interest, including wildlife reserves and museums. We also offer small educational grants to local schools and colleges for suitable projects, so far this year disbursing approximately £1,500 to three schools in the region.

This website also lists external events of note in its events calendar.


Details of the membership fees and directions to the main venues used by the Society can be found on the Members area of this website.
