Design of Possible Organic Photovoltaic Compounds and Their Initial Computational Assessment
- Albert Ochoa CastilloChemistryUndergraduate Student
College of Natural Resources & Sciences
The excessive use of fossil fuels has surged the need for alternative energy sources, such as solar energy. Here, possible organic photovoltaic (OPV) compounds were designed and their initial computational assessment was done. Density Functional Theory was used to calculate the HOMO-LUMO gap of the 26 compounds designed. Semiconductors such as naphthalene, 1,1’-biphenyl, and ɑ-septithiophene were used as the backbone and the main electron-withdrawing group (EWG) used was thien[3,4-c] [1,2,5]thiadiazole-2-sIV(8CI,9CI), among other thieno-thiadiazole derivatives.
Effect of Channel Size on the Development of Resistance in a Carbon Nanotube Network

College of Natural Resources & Sciences
The burgeoning demand for nanotechnology presents a specific issue in that it requires the production of electronic components at a physical scale that is difficult and costly to achieve. Carbon nanotubes (CNTs) have potential in a wide range of electronics applications (1), but there are many lingering questions about their behavior. This project seeks to use computational modeling to propose a relationship between the number of CNT-on-CNT contacts and the effective resistance of a CNT network as the physical parameters change.
Effects of Visual and Verbal Prompting on the Badminton Overhand Swing
- Nastya YudinovaKinesiology and Recreation AdministrationGraduate Student
College of Professional Studies
The purpose of this study was to evaluate the effectiveness of verbal and visual prompting during balloon badminton on the number of correct overhand badminton swings (OBS), also known as clears, of an 8-year-old female subject with spastic cerebral palsy. Using a 4-week ABAB design, the intervention was found to be effective at improving the rate of correctly performed OBSs by as much as 30% on a weekly average between baseline and intervention phases and by as much as 37.5% overall.

Fungi Decomposition Rates in Relation to Growth Rate and Moisture Tolerance
- Ana SammelMathematicsUndergraduate Student
- Emma VillegasMathematicsUndergraduate Student
- Bridget OppermanMathematicsUndergraduate Student
College of Natural Resources & Sciences
Researchers found that fungi that grow faster tend to be less resistant to changes in temperature and moisture. Exploring the relationship between a fungus’s growth rate and moisture tolerance, our team used a system of differential equations to model the decomposition rates of woody material by different fungi to understand how decomposition would be affected when the species are in competition.
Future Flights
- Jaye ChangEcological RestorationUndergraduate Student
College of Natural Resources & Sciences
In hopes of increasing STEM students in colleges this project is geared towards high schoolers with the idea that since they are quite adept to todays technology they may be interested in drone technology, either flying, programing, or learning how drones help in the scientific community.
Germination and Survival in Knobcone Pine Seedlings in a Common Garden Experiment at Schatz Demonstration Tree Farm

- David GreeneForestry and Wildland ResourcesFaculty
College of Natural Resources & Sciences
This study examines knobcone pine (Pinus attenuata) germination success from stratification to transplanting into a common garden at the Schatz Demonstration Tree Farm. Seeds were sown in containers in the greenhouse after three week of cold stratification and transplanted to garden beds a month later. Of 840 seeds sown, 538 were germinated (64%). 256 seedlings were outplanted and 192 of these survived (75%±15). The seedlings grew to an average height of 7.5 cm ± 2 cm. Our findings are part of a larger study to understand the water requirements for the survival of tree germinants in a Mediterranean climate.

Grieg Piano Sonata in E minor
- Owen ReissMusicUndergraduate Student
College of Arts, Humanities & Social Sciences
Grieg wrote his only piano sonata early in his life, when he was still learning how to be a composer. It is an imperfect work, but very emotional and passionate. I play only the first movement, Allegro moderato.
