Remotely Controlled Colloids, Interfaces, and Biosystems

Colloids at interfaces: Pinned down.

In 1903 Walter Ramsden found that an air bubble placed in a liquid suspension of microscopic particles “can be seen to pick up the particles ... and to retain them obstinately ...”1 Ramsden had discovered the strong affinity of colloidal particles to fluid interfaces, an affinity that a century later can be harnessed to make microstructured materials such as Pickering emulsions, colloidosomes a...

Colloids at Liquid-liquid Interfaces

Liquid-vapor interfaces of patchy colloids.

We investigate the liquid-vapor interface of a model of patchy colloids. This model consists of hard spheres decorated with short-ranged attractive sites ("patches") of different types on their surfaces. We focus on a one-component fluid with two patches of type A and nine patches of type B (2A9B colloids), which has been found to exhibit reentrant liquid-vapor coexistence curves and very low-d...

Remotely Controlled Automated Horse Jump

With the application of automation, a horse jump can be controlled with the push of a button, or even a remote control. This enables the rider to adjust the jump to suit their needs while still on their horse. The objective of this work is to design and build a wireless remote motor controller which will be applied to a prototype horse jump. The user will be able to control the forward and reve...
