Photorefractive properties of liquid crystal-filled bacterial cellulose mats
The photorefractive effect is a phenomenon associated with nonlinear optical materials in which the refractive index of the material varies with the application of light. One demonstration of this effect is dynamic holography. Energy transfer between diffracted beams...

Nicholas Barron with Jaoa Maia and Ed CanerLow Temperature Suspension of Shear Thickening non-Newtonian FluidsThere are a variety of useful applications in industry for shear thickening non-Newtonian fluids. For certain applications, maintaining shear thickening properties for long periods of time at temperatures below -25 Centigrade is desirable. In this...
Rachel Capelouto with Rolfe PetschekOrientation Waves in Colloidal Crystals Crystals are usually thought of as the condensation of density waves. However, in some systems, notably blue phase liquid crystals, and, according to recent results in our group also hard tetrahedra, the formation of a crystal comes from the condensation...
John Dulin with Glenn StarkmanHearing the Shape of the UniverseThe past few years of work on discerning the topology of the universe have focused on methods like cosmic crystallography and circles-in-the-sky searches, as well as examinations of the correlation matrix to uncover manifolds with non-trivial topology. While helping to...
Joseph Flannery with Harsh MathurDirac theory of topological insulator boundariesA topological insulator is a material that behaves as an insulator in its interior but whose surface contains bound conducting states. The bulk of a topological insulator may be described by a massive Dirac model while the gapless surface states follow the massless Dirac...
Methods for the Improvement of High Energy Cosmic Ray Shower SimulationsJohnathan Harper with Corbin CovaultExotic forms of matter such as Quark Gluon Plasma and Dark Matter are difficult to detect. Before attempting to directly observe evidence of them in cosmic ray showers, it is advantageous to first perform simulations...
Stephanie Hougen with Mark GriswoldModeling Magnetic Resonance Fingerprinting Signals in the Presence of ExchangeMagnetic resonance imaging (MRI) has many applications in our current healthcare system. The MRI group at CWRU has recently introduced a new imaging technique, magnetic resonance fingerprinting (MRF), that presents a new quantitative approach to imaging....
Seth Kimble with Robert DeisslerOptimization of Optical Based Malaria DetectionThe detection of malaria present in humans has been shown to be possible by measuring the absorption of laser light as a magnetic field is applied to a blood sample containing the paramagnetic malaria hemozoin. However, current systems rely on...
Sean Kinzler with Michael MartensDesign of a Persistent Switch for 0.35T Magnesium DiBoride Superconducting MagnetsRecent progress in magnet design and persistent joints using for the magnesium diboride, MgB2, superconductor has made clear the increasingly important role of the persistent switch in magnet quench protection. The persistent switch is used...
Vipul Malik with Philip FengImproving the I-V characteristics of Molydinium DiSulfide transistors h-Boron NitrideMolybdenum disulfide (MoS2) transistors have attracted considerable attention. Molybdenum disulfide (MoS2) transistors on boron nitride (BN) substrates in particular show interesting I-V characteristics. Unfortunately these transistor devices currently exhibit undesirable I-V characteristics at low temperatures due to...
