Ultrasonic Levitation, Trapping and Manipulation and its Practical Applications in Condensed Matter Physics

20 November 2017, 5.00 PM - 20 November 2017, 6.00 PM

Dr Adrian Barnes (Physics, Bristol)

Frank Lecture Theatre H H Wills Physics Laboratory, Tyndall Avenue, Bristol BS8 1TL

The trapping of particles in acoustic standing waves has long been known and is often demonstrated, for example, by the Kundt’s tube apparatus. However, despite this well-known demonstration few practical applications of trapping in acoustic fields have been demonstrated. In this talk I will review recent work we have carried out using simple, practical devices, that can be used for trapping and manipulation from the millimetre to the micron scale. Examples given will include the acoustic trapping of liquids and the formation of glasses in air, particle and cell trapping and manipulation in water and the formation of micron structured gels from chemical coascervate droplets.  

*These colloquia start at 17:00 on Mondays in the Frank lecture theatre.
