The Effect of Thermal Annealing on Phase Separation in Organic Photovoltaic Films
(2015)In our research, we used amplitude modulated atomic force microscopy to study the effect of thermal annealing on the morphology of four recently developed bulk heterojunction photovoltaic films. Each cell was fabricated ... -
Effective Surface Areas and Adsorption Capacity of Graphene with Vacancies
(2023)Graphene has been heavily researched since Geim and Novosolov won the nobel prize in physics for its mechanical exfoliation from graphite. The atomically thin crystal of carbon atoms has been reported to have novel properties ... -
Observing the Sedimentation of TiO2 Nanoparticles in Aqueous Solution Using a Quartz Crystal Microbalance with Dissipation Monitoring
(University of Missouri--Kansas City, 2016)The development of a novel and less expensive approach to the quartz crystal microbalance with dissipation monitoring (QCM-D) is explored. Using a vector network analyzer (VNA) to measure harmonic ranges from the primary ... -
Photosensitivity and Magnetosensitivity of The Drosophila Circadian Clock
(2014)The experiments in this thesis addressed whether magnetic fields can enhance entrainment (phase determination) of the circadian clock by light. The experiments were conducted using a species of small fruit flies, Drosophila ... -
Using current sensing atomic force microscopy to study heterogeneous materials
(University of Missouri--Kansas City, 2012-08-27)Two kinds of heterogeneous materials, block copolymer films and Nafion membranes, are studied by using current sensing atomic force microscopy (CSAFM). In the calculated results, correlation between surface morphology ...
