This report on solar neutrino experiments will include a summary of the results of the chlorine detector, and an account of our plans to build a gallium solar neutrino experiment. In addition to discussing the experimental side of the solar neutrino problem I would like to relate our experiences during the last 15 years in working in the Homestake Gold Mine. In the course of our work at Homestake a number of independent groups have asked to use our facilities and, because of the cooperative and helpful attitude of the Mine management, these experimentalists could be easily accommodated. A brief account of these experiences may be useful for the main business of this workshop, building large particle detectors for observing nucleon decay, and the related question of the need for a national underground physics facility.

Synthetic dispersants are commonly used in the stabilization of various colloidal suspensions. However, their non-biodegradable and toxic natures hamper their industrial use. The use of natural polymers as dispersants for various colloidal suspensions has been reported in the past, but the incentive for producing highly efficient natural polymeric dispersants is high. Lignin and xylan are the most abundant and sustainable natural polymers on earth, which are produced as by-products of pulping and cellulosic ethanol industries. These chemicals can be considered as the raw materials for producing value added products such as dispersants. In this dissertation, the anionic modification of kraft lignin and xylan via carboxymethylation, sulfomethylation and oxidation were comprehensively investigated and the applications of the products as dispersants in kaolin and coal suspensions were systematically assessed. The influence of reaction conditions on charge density and solubility of kraft lignin or xylan were systematically investigated. The anionic products obtained were characterized using NMR, FTIR, TGA, molecular weight and elemental analyses. The adsorption of anionic lignin or xylan on kaolin and coal particles and their effect on zeta potential of the suspensions was comprehensively assessed. The relative turbidity and viscosity analyses of colloidal suspensions confirmed the better dispersion performance of the products compared with commercial ones. The impact of dispersant dosage, pH of the suspension and time of mixing on dispersant performance of anionic lignin or xylan in kaolin and coal suspensions was also studied. The dispersion efficiency of suspensions found to increase with anionic lignin or xylan dosage and time of mixing. The dispersion efficiency of anionic lignin or xylan was at maximum under neutral conditions. The influences of molecular weight and charge density on the dispersant performance of anionic lignin in kaolin suspensions were also studied. The results showed that a highly charged ...

Wave energy is an important renewable energy source. Previous studies of wave energy conversion (WEC) have focused on the maximum power take-off (PTO) techniques of a single machine. However, there is a lack of research on the energy and power quality of wave farm systems. Owing to the pulsating nature of ocean waves and popular PTO devices, the generated electrical power suffers from severe fluctuations. Existing solutions require extra energy storage and overrated power converters for wave power integration. In this study, we developed a master-slave wave farm system with rotor inertia energy storage; this system delivers self-smoothed power output to the grid and reduces the number of converters. Two control methods based on the moving average filter (MAF) and energy filter (EF) are proposed to smooth the output power of wave farms. RTDS simulations show that the proposed systems and control methods facilitate simple and smooth grid integration of wave energy. Keywords: Wave farm, Energy storage, Power smoothing, Power quality, Energy quality

Eight Argonne Premium Coal Samples (APCS) were weathered in air and the structural and chemical changes that upon swelling with toluene and pyridine were, examined by an EPR spin probe method developed in this laboratory. Under mild oxidation conditions and swelling with toluene large structural changes were observed for lignite (Beulah-Zap) which suggested the collapse of the coal structure. This did not occur for higher rank coal. Upon oxidation and swelling with toluene and pyridine an increase occurred in the amino substituted spin probe concentration for coals with the carbon percent above 80%. A maximum was found for the creation of 5 {Angstrom} diameter pores upon swelling with pyridine at 85% C.

The Department of Physics, in collaboration with the Department of Chemistry and Biochemistry and the Department of Earth Sciences, is [proposing to create a program in Engineering Technology. The proposed B.S. Engineering Technology degree will target students who want to pursue engineering and are looking for a school that offers a dedicated program. We believe the specializations in Sustainable Energy, Advanced Manufacturing and Semiconductor Materials will appeal to students interested in creating a more sustainable world and address the need for a technologically trained workforce in Upstate New York. Upon graduation of the inaugural class, accreitation for the program will be sought from the Accreditation Board for Engineering and Technology (ABET). ; Monier, Eric Undergraduate Curriculum and Policies

The uptake of energy-efficiency investments in the residential sector is relatively low, despite evidence of short payback periods and numerous co-benefits, including increased home comfort and reduced negative environmental impacts. Common barriers facing homeowners include financial and time constraints, competing priorities, and a lack of adequate information. Home energy audits are an established approach to encourage energy-efficiency investments, with the intention of overcoming the informational barrier by providing personalized energy-efficiency recommendations to homeowners. However, literature suggests that the impacts of these audits are mixed, due to a lack of guidance, procedural information and support from social networks. To fill this gap, the Home Energy Coach program was piloted in Waterloo Region, Ontario, involving government, non-profit, industry and academic stakeholders. Upon receiving an EnerGuide home energy evaluation, homeowners were eligible to participate in free consultation sessions with an Energy Coach to help develop and execute a renovation plan. This thesis documented the coach interactions and renovation progress of 21 program participants through a series of online surveys, with added insight from follow-up interviews with five of these participants. The results indicated that the Energy Coach was helpful in the development of renovation plans of many participants by clarifying the audit recommendations, helping to evaluate options based on each household’s circumstances and guiding participants to additional resources. At the end of the program, 17 out of 18 exit survey respondents had made progress on or completed at least one-energy efficiency measure, with an overall conversion rate of 29 percent from audit recommendation to completed action. The most frequently completed measures were basement/crawl space insulation, draftproofing and window/door replacement, which were also the most frequently recommended measures. This thesis adds to the literature on motivations and ...
