LAMPSe is proud to anounce that Francesco Greco and Matthias Gritzner won the third price in the audience vote of the photo competition held at TU Graz called TU Graz SciPix.

The photos show examples of the everyday research at TU Graz.

 

Francesco Greco was participating with a photo made by Matthias Gritzner during his bachelor thesis and shows UV ink contained in microfluidic channels made from hydrophilic and hydrophobic LIG.

Liquid Yin&Yang on laser induced graphene
A Yin&Yang symbol is formed by self-guidance and mixing of fluorescent dyes in water on top of a pattern of Laser Induced Graphene with tunable wettability (superhydrophilic/superhydrophobic).

Here you can see video of the microfluidics created with LIG. Fluorescent dyes are deposited on the LIG tracks and are guided down to the bottom because of the hydrophilic properties. At the bottom they come in contact with each other and form a Yin&Yang symbol. The liquid is confined by the hydrophobic LIG on the outside.

Alexander Dallinger is participating with a scanning electron microscope image showing LIG and silver flakes forming a “glacier”.

The everlasting silver glacier
The glacier is formed by silver flakes on mountains of laser-induced graphene, arising from a plastic sheet after scribing with an infrared laser. The glacier is forcing its way down the valley and is connecting the conductive mountains together.
