Near-Field Thermal Radiation In Graphene-Based Systems, Hua Lin
Near-Field Thermal Radiation In Graphene-Based Systems, Hua Lin
Honors College
Radiative heat transfer between two media separated by a sub-wavelength distance (the dominant wavelength of thermal radiation at room temperature is around 10 m.) is referred to as near-field radiative heat transfer (NFRHT). Graphene was found to have one of the greatest levels of NFRHT [1]. Additionally, NFRHT of graphene can be modulated externally via application of a bias voltage to the material [1][2], thereby altering its Fermi energy level. As such, graphene is an ideal candidate for several applications such as NFRHT for thermal switching, nano-gap thermophotovoltaic waste heat recovery, and thermal rectification. Modulation ratios as large as 77.7274 …
Life Cycle Analysis And Implications Of 3d Printed Bio-Based Homes, A Preliminary Study, Claire Liedtka
Life Cycle Analysis And Implications Of 3d Printed Bio-Based Homes, A Preliminary Study, Claire Liedtka
Honors College
The purpose of this study is to evaluate the life cycle, embodied energy, and sustainability potential for large scale additive manufacturing of 3D printed homes. Additive manufacturing is the process of selectively depositing materials using a 3D printing process, which optimizes material usage and reduces waste. I performed a preliminary Cradle to Cradle Life Cycle Analysis for constructing 3D printed homes using a bio-based material, poly-lactic acid (PLA) filled with wood flour. For purposes of this study, I consider the Life Cycle Analysis to be the environmental assessment of each stage of a product’s life cycle, from material sourcing, processing, …
Development Of Porous Polymeric Implants For Use In Orthopedic Research And Development Applications, Alexander Caddell
Development Of Porous Polymeric Implants For Use In Orthopedic Research And Development Applications, Alexander Caddell
Honors College
Current orthopedic implants comprised of plastic, ceramic, or metal alloys are susceptible to surface degradation at the implant-implant interface. The resulting microscopic fragments cause tissue irritation that can lead to osteolysis. In addition, existing percutaneous implants, such as pins used to stabilize fractures, are prone to bacterial infections due to the inability of the surrounding soft tissue to adhere to the implant and form a biologic seal. The goal of this Honors Thesis was to develop porous polymeric implants for orthopedic research and development applications that improve upon current designs in an attempt to remedy the issues detailed above.
