Aggregation Characteristics of Conjugated Sophorolipid-(Zn)porphyrin Polymers

George Heidbreder with Kenneth Singer Aggregation Characteristics of Conjugated Sophorolipid-(Zn)porphyrin Polymers Bio-based, self-organizing molecules are of considerable interest for optoelectronic device applications due to their functionality and ability to construct sophisticated microstructures with similar motifs to those found in nature.  Recently, the Singer group has discovered that conjugated sophorolipid-(Zn)porphyrin molecules self-assemble...

Deposition and characterization of ZnSnSb2 for phase transition studies

Kevin Kwock with Kathleen Kash and Gary Chottiner Deposition and characterization of ZnSnSb2 for phase transition studies ZnSnSb2 (zinc tin antimonide) is predicted to have interesting crystal structures, phase transitions, and thermoelectric properties that have not yet been carefully confirmed by experiment. The objective of this study is to produce, characterize...

Characterization of Gas-Liquid Interfaces in Passive Cyclonic Separators

Ru-Ching Chen with Yasuhiro Kamotani (Mechanical and Aerospace Engineering) Characterization of Gas-Liquid Interfaces in Passive Cyclonic Separators Two-phase flows and their separation is an important research topic as many spacecraft require such functionality to remain operational. These systems are not required on earth due to the existence of buoyancy. Cyclonic...

Photorefractive properties of liquid crystal-filled bacterial cellulose mats

Caroline Novak with Kenneth Singer 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...
