- Description:
- The functions of lubricants in moving interfaces are extensive; lubricants minimize friction, transfer heat, clean the rubbing surfaces, extract debris, and diminish wear. Rather than using separate lubricants for each of the functions, it is more desirable to make one lubricant serve multiple purposes, or a muti-functional lubricant. The goals...

- Description:
- Morality has been viewed as a core aspect of the self and even a basic psychological need. Strategies for regulating threats to moral self-views may therefore be distinct from regulating threats to other self-aspects. Consistent with research on the regulation of basic psychological needs, I hypothesized that threats to the...

- Description:
- The continuing increase in atmospheric CO2 to concentrations exceeding 400 ppm has attracted considerable attention from both scientists and policymakers. Industrial fossil fuel consumption generates a significant amount of CO2 emissions, and in particular, energy-intensive molecular separations that require thermal processes, such as distillation, drying, or evaporation, are responsible for...

- Description:
- Lignin is the largest store of renewable aromatic carbon. Due to its refractory nature, however, its chemical potential is not fully realized, rather, most lignin is treated as a waste, burned for low-value energy. Here, we propose a biorefinery where the treatment of wastewater by a microbial electrolysis cell (MEC)...

- Description:
- Directional freeze-casting is a porous materials fabrication technique that is used to create materials with complex, three-dimensional pore structures. Particle suspensions are solidified under a thermal gradient, promoting anisotropic growth of dendrites and incorporation of particles within interdendritic space. A fully-solidified directional freeze-cast structure is composed of dendrites that are...

- This thesis investigates Hugo von Hofmannsthal’s undermining of soteriological poetics in his comedy Der Schwierige (“The Difficult Man”), with a focus on the complex interplay between meta-language (e.g., stage directions) and dramatic dialogue, normative and contingent speech (i.e., ‘ironic speech’). By challenging what I term the “soteriological agenda” of comedy...

MRI Examination of Brain Structure and Function in Breast Cancer Patients Undergoing Hormone Therapy
- Description:
- Breast cancer patients have reported nonspecific neurologic symptoms such as fatigue, depression, and cognitive concerns while undergoing adjuvant therapy. Few neuroimaging studies have examined hormone therapy, an adjuvant therapy, and more research is needed to determine possible neurologic and cognitive effects. Previous estrogen research has found alterations in gray matter...
