How does the interplay between chirality in liquid crystals and the shape of inkjet printed droplets affect the structures that form within them? We answer this in a paper in @softmatter by @alvacjorr with X.Qiu, @FluidsTom, @waqaskamal16, and @alfonsoacp doi.org/10.1039/d4sm00541d

Topologically frustrated structures in inkjet printed chiral nematic liquid crystal droplets –...

Director field alignment in inkjet printed droplets of chiral nematic liquid crystalline materials is investigated using both experiments and numerical simulations. Experimental investigations are...

The mechanism behind this was identified using advanced numerical simulations in collaboration with Julia Yeomans @OxfordPhysics, showing that randomness in the initial quench of the nematic droplet during the printing process can lead to different outcomes.

This is Alva's first first-author paper, and they cap the paper off with beautiful images of very strongly chiral droplets, which develop a colourful fingerprint texture in both the experiments and simulations! Thanks to @oxengsci, @royalsociety, @EPSRC and John Fell Fund Oxford!

In this work, we explore how the impact of a drop onto a pool is modified by the presence of a floating layer of an immiscible liquid. In these movies we show a drop of water impacting a layer of silicone oil floating on a pool of water: experiments and simulations agree well!
