Photonic Bandgap Microcapsule

GTPN-COPE researchers have microfluidically prepared microcapsules with of a fluidic photon upconverting core and photonic shell from a triple emulsion as a template. The achievable dimensions and compositional flexibility of the upconverting core and photonic shell suggest a range of opportunities the future design of low-threshold photonic devices.

Soft Matter Incubator (SMI) researcher Prof. Elisabetta Matsumoto is part of a team of researchers that is helping bring hyperbolic space to anyone with a virtual reality (VR) headset. The effort is designed to allow users to experience non-Euclidean spaces in which parallel lines diverge (hyperbolic space) that can be difficult to fully imagine with purely mathematical considerations. The research was recently part of the News in Focus in Nature. Find out more here.

Soft Matter Incubator (SMI) researchers have created water-filled particles known as microgels within robust polymer networks made of natural fibrin. In a remarkably dynamic process, the microgels self-assemble into three-dimensional tunnel-like structures that could allow repair cells to migrate through the polymer network to begin the healing process.

The Soft Matter Lunch & Posters event welcomes researchers working in all areas of soft matter at Georgia Tech to participate and share your latest and greatest discoveries. There will be two concurrent poster sessions on anything squishy. A free lunch will be provided. All participants may present a poster (size limit 30” x 40”). Come network with fellow graduate students, post doctoral fellows and faculty while showcasing your exciting research! Registration is free but required.

Dense packing of spheres in cylinders
Dr. Adil Mughal
Aberystwyth University

We study the optimal packing of hard spheres in an infinitely long cylinder [1-4]. Our simulations have yielded dozens of periodic, mechanically stable, structures as the ratio of the cylinder (D) to sphere (d) diameter is varied. Up to D/d=2.715 the densest structures are composed entirely of spheres which are in contact with the cylinder. The density reaches a maximum at discrete values of D/d when a maximum number of contacts are established. These maximal contact packings are of the classic "phyllotactic" type, familiar in biology. However, between these points we observe another type of packing, termed line-slip.
