Nitrate (NO₃-) accumulation in water sources is a serious health and environmental concern. Common methods used to reduce NO₃- accumulation have one or more undesirable traits that limit their efficacy in large-scale decontamination. However, treatment of NO₃- electrochemically is a promising area of study because of the absence of toxic...
Nitrate is a toxic surface and ground water contaminant that poses human-health and ecological hazards. Contamination is anthropogenically sourced to over-amendment of ammonia-based fertilizers, in turn generated by the most carbon intensive chemical process in use today. Electrochemical approaches offer a green alternative to transform harmful waste nitrate into value-added...
Histones, as part of nucleosomes, are responsible for DNA packaging in chromosomes. They also affect DNA expression by a multitude of post-translational modifications, especially prevalent on the amino terminus of histones. Co-activator protein complexes “write”, “read”, or “erase” histone modifications, and in balance determine which sections of DNA are free...
Significant challenges remain before lithium-ion batteries can support the decarbonization of the transportation and power sectors required to avert catastrophic climate change. The energy density of these batteries must be increased, while decreasing the price, and maintaining or increasing their lifespan. To improve the practical energy density of existing materials,...
People are increasingly staring at device screens which emit predominantly blue light. Because LED technology is relatively new, we do not know what effects blue light has on our long-term health. Blue light exposure leads to a dramatic decrease in longevity in Drosophila, thus this study aims to explore possible...
Background. Flourishing is negatively related with depression, but has been proposed as a separate axis and an independent aspect of overall mental health. One factor that has been shown to affect both depression and flourishing is racial discrimination. This study hypothesizes that, in young undergraduate women of color, discrimination experiences...
Industrial waste heat composed of saturated liquid water can be redirected to charge a thermochemical energy storage (TCES) system. This energy can be stored long-term in the inherently energy-dense chemical bonds and used for space heating. Initial reactor scale cycling experiments were conducted in tandem with TCES material improvements. Hydration...
Molybdenum disulfide (MoS2) has potential applications as a low-cost catalyst for the hydrogen evolution reaction (HER). Defects on MoS2, such as edge sites and sulfur vacancies, are known to be the major active sites for HER. Controlling the formation of these defects allows for the enhancement in reactivity of MoS2...
Lanthanide (Ln) based molecular complexes have shown great potential as Lewis acid catalysts for the activation of small molecules. Despite the wealth of structural versatility and high catalytic activity of these complexes, they often lack selectivity and recyclability. This hinders their potential for use in large-scale industrial applications where waste...
The rapid advance of concrete engineering in the
West has made necessary reliable information as to the
strength qualities of the most important marketable, sands
In the eastern states, theory and practice have advanced
hand in hand, by the investigation of the constituent
materials of concrete. In the West, no...
