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...

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...

Aluminum zinc oxide transparent conductors for optical cavity enhanced polymer photovoltaics

Emily Griffin with Ken Singer Aluminum zinc oxide transparent conductors for optical cavity enhanced polymer photovoltaics Indium tin oxide is the ubiquitous transparent conductor used in all liquid crystal displays and thin film photovoltaic devices.  Indium, however, is a rare and relatively expensive material, leading to intense research to replace it...
