About 71 % of the surface of Earth is water, out of which around 2.5 % is freshwater. The majority of the surface of Earth is occupied by seawater which also contains dissolved salt. The salt concentration in seawater makes it toxic to humans because the human body is unable to get rid of the salt that comes from seawater. The demand for fresh water is increasing due to the rise in global population. In this context, desalinated seawater is considered as a viable resource to meet the growing demand for fresh water. Desalination process is highly energy intensive due …

Honors Theses
Upconversion (UC) is the conversion of low energy light to higher energy light. It is utilized for a broad range of applications such as solar energy harvesting, microscopy of cellular biology, and cancer therapy. Specifically, triplet-triplet annihilation UC (TTA-UC) involves two dye species, a sensitizer and an annihilator, which are capable of upconverting noncoherent light such as sunlight. Traditionally, TTA-UC is achieved in solution, rubbers, or glasses, however, this work probes the capabilities of a thermoplastic elastomer (TPE) matrix to examine the effect of phase-separated morphology on the energy transfers necessary for TTA-UC. The system herein consists of poly(styrene-isobutylene-styrene) (SIBstar) …
