Featured Liquid Crystal Picture Art of the Month
©John Sandford O'Neill
A polymer channel laser-written in a pi-cell liquid crystal device, inspired by developments in microfluidics technology. The device is relaxing to a topologically discontinuous director state and the transition is confined and unable to penetrate through the topologically discontinuous polymer walls. Scale for image: the central channel is 45 µm in width.
I find it visually very attractive with the distribution of different spreading lines and the positioning of shapes of different colours. The connection to the microfluidics technology is of course technologically and scientifically very interesting a new to the field.
