This dissertation describes the relationship between the surface chemistry of colloidal semiconductor nanocrystals (quantum dots, QDs) and their optoelectronic properties, such as photoluminescence and degree of quantum confinement. We primarily focus our efforts on one particular subset of ligands known to couple strongly to the inorganic core of the QD...
Climate change may be one of the most important puzzles the world has attempted to solve and one of the greatest challenges in this area is to improve our understanding of how atmospheric aerosol particles impact climate processes. We seek to overcome this challenge by focusing on the chemistry and...
Woodstock—the word is shorthand for the spirit of the 1960s counterculture. Yet the assumption that the 1960s dawned a “New Age” neglects contributions made by earlier generations of Woodstock artists in advancing a utopian vision of emancipated art, life, and labor. From 1902 onwards, Woodstock—a small Dutch hamlet in upstate...
The over-a-decade quantitative study of the flexion synergy has provided concrete evidence that the stereotypical movement coupling of shoulder abduction with elbow flexion and wrist/finger flexion (i.e. flexion synergy) significantly affects the ability to perform functional upper extremity movements that are essential for activities of daily living (e.g. reach-to-grasp an...
Using cross-sectional and 90-day discharge follow-up data from child welfare residential treatment, this study investigates gender differences in characteristics, needs, and strengths at entry to residential treatment. Specifically, this analysis examines trauma experiences, trauma-related symptoms, internalizing and externalizing behaviors, and strengths, in relation to length of stay and discharge status...
In the last twenty years, memory entrepreneurs have proliferated memories of Communism from Central and Eastern Europe transnationally across Europe, but for some an invisible Iron Curtain persists. How has the European memory field changed in the last two decades, and more broadly, what determines which mnemonic actors are successful...
The patent system seeks to strike the ideal balance between competition and the rate of innovation – not to maximize innovation unconditionally. Clearly there must be limits on the manner and degree to which patents are used to diminish competition. A critical complication, however, is that this boundary is often...
DNA methylation in repetitive elements (RE) suppresses their mobility and maintains genomic stability, and decreases in it are frequently observed in tumor and/or surrogate tissues. Averaging methylation across RE in the genome is widely used to quantify global methylation. Methylation of RE in humans is considered a surrogate for global...
Most people imagine hacking to be an exceedingly complex crime, requiring an understanding of computing systems that goes far beyond that of average, functionally literate PC users. While there are sophisticated hacking techniques which do fit this description, many forms of hacking require little more than the ability to install...
In February, British Prime Minister David Cameron announced that Britain would vote on the continuation of their membership within the EU. This has led to ministers quickly splitting into factions either in support or opposition to British exit from the EU, now often referred to as “Brexit”. Positions have been...
