Extreme Dynamics Of Nanomaterials Under High-Rate Mechanical Stimuli, Wanting Xie
Extreme Dynamics Of Nanomaterials Under High-Rate Mechanical Stimuli, Wanting Xie
Doctoral Dissertations
Nanomaterials demonstrate novel mechanical properties attributed to the extremely large interfacial area. At quasi-static rates, the interfacial interactions are crucial in mechanical behaviors, however, materials under extreme mechanical stimuli are rarely studied at nanoscale. With an advanced laser-induced projectile impact test, we perform supersonic impact of micro-projectiles on polymer films, multilayer graphene, carbon- based nanocomposites membranes as well as individual micro-fibers, to study the interface interactions in the high-rate regime, and develop a simplified model to characterize the ballistic performance of materials.
A Model For Sustaining New Technology Based On Government Incentives, Girish Upreti
A Model For Sustaining New Technology Based On Government Incentives, Girish Upreti
Doctoral Dissertations
The diffusion of new technology that provides environmental benefits may require government incentives for a duration of time, especially when the technology is expensive. The Center of Systems Research and Education (CASRE) model is developed that analyzes the impact of incentives in sustaining new technologies to allow their social acceptance. The CASRE model includes both demand and supply variables associated with incentive policy to sustain new technology. The key to market dissemination and sustainability is the Investment Tax Credit (ITC) levels provided by the government. The level of ITC is based on the current cost to the customer and the …
