Thursday, 15 August
15:00 – 17:30
Evelyn Sokolowski, Å101136 Room
The demonstrations room has acoustofluidic systems under development. You will see how well these systems perform in the real world. The Acoustofluidic Olympics will take place during the demonstration session where all systems will be open to your full scrutiny.
THE ECHOGRID - THE WORLD'S FASTEST MICROPLASTIC ENRICHMENT DEVICE!
Martim Costa
KTH, SWEDEN
We will demonstrate the EchoGrid, which is an acoustofluidic chip used for upconcentrating microplastics from dilute liquid samples. The chip is based on a surface displacement transducer combined with a PDMS flow chamber, and utilizes silica seed particles for trapping and enriching microplastics at relatively high flow rates. The device has recently been described in this publication: M. Costa et al., Anal. Chem. 2024, 96, 23, 9493 - 9502 (https://doi.org/10.1021/acs.analchem.4c00933).
A FRUGAL, SELF-SUSTAINING ACOUSTOFLUIDICS BIOREACTOR DEMONSTRATOR
Gabriel Dumy
KOLIBRI, FRANCE
This is a much simplified version of our bioreactor that was made for education purposes, but that exhibit how the acoustofluidics methods that are exploited in a conference such as ours can be efficiently implemented with quite few material and devices. For less than 400€, this small bioreactor system generates a complete culture column, that can shift its position in space, in accordance to the temperature and constrains imposed to the system. Real time control is achieved on said position, and the fluid cavity (about 30mL) is projected on a large screen.
NM-PARTICLE TRAPPING IN A PACKED BED
Michael Gerlt
Lund University, SWEDEN
We demonstrate trapping of 270 nm fluorescent particles in a capillary filled with 100 µm polystyrene particles. The setup consists of syringe pumps, the trapping device and a dynolite camera for fluorescence analysis.
3 NODE TYPES IN DIFFERENT CHANNELS ON ONE MICROSCOPE SLIDE
Jeremy Hawkes
Acoustic Machines, UK
Liquids in capillary bridge channels run in parallel on a microscope slide. The channel depths range from 0.15 mm to 1 mm and particles simultaneously move to the nodes in each liquid bridge. Different node patterns form at each channel depth. The nodes are produced by resonances in: 1) the top film, 2) the liquid and 3) the glass. The nodes from each resonant source appear independently and separated by the channel depth because at each depth a resonance from only one origin dominates.
This year the conference is inviting all delegates to bring a tabletop acoustofluidic system to demonstrate.
Deadline to book a table:
Saturday, 1 June 2024.
Demonstrations will be set up and delivered like the posters, in a flea market style. You will also get the opportunity to win a medal in the Acoustofluidic Olympic Games. In the Olympics, we expect to measure and record acoustofluidic feats such as: Fastest moving and highest jumping particle or droplet or lifting the heaviest particle or droplet, the tightest grip, greatest precision placement, highest flow rate etc. You can create a category appropriate for your system. There will also be a prize for the best demonstration, as voted by attendees.
You could bring:
- The system you are currently working on.
- A system which could make a good teaching aid.
- A peculiar acoustic phenomenon.
- An overlooked acoustofluidic phenomena seen in everyday life e.g. vortex rings, Chladni figures, the sound of cavitation from splashing water, standing waves formed when you hold your finger under a slow running tap etc.
If you are able to bring a demonstration please complete the
table reservation form (pdf).
The reservation form should be sent to
info@acoustofluidics.net with a Deadline of Saturday, 1 June 2024.
Please feel free to send any questions regarding the event to Jeremy Hawkes at
JeremyJhawkes@gmail.com
Some rules:
- You will need to complete a risk assessment and your equipment will be PAT tested on arrival (if not already valid).
- Commercial systems are welcome in paid for booth spaces, this is available separately (please contact exhibits@acoustofluidics.net). However companies are welcome to give demonstrations and enter the Olympics. We encourage companies to demonstrate curious novelties rather than their core product during this event.
- We will provide a power socket and access to water.
- It is free to enter a demo (and there is potential to book local student demonstrators for help if required).
