REU Site: Explore It! Building the Next Generation of Sustainable Forest Bioproduct Researchers
The major goal of the project is to create the next generation of sustainable forest bioproduct researchers through providing them with an outstanding and relevant research experience
Explore it! Building the Next Generation of Sustainable Energy Researchers
This award will establish an REU Site at the University of Maine. The program will engage 10 undergraduates each year for three years in a 10-week summer research experience. This REU site will leverage a focus area represented by the newly established University of Maine Forest Bio-products Research Institute (FBRI). Undergraduate students will conduct research advancing their knowledge of sustainable forest bio-products and will gain a detailed understanding of one of the thematic elements of the research effort as well as a broad understanding of all areas, specifically: 1) sustainable and life cycle analysis; 2) solids extraction/modification; 3) process control and sensing; 4) nanocellulose production and utilization; and 5) new project development. In addition to the hands-on research experience, undergraduate students will participate in a seminar series, field trips to gain practical knowledge of various aspects of sustainable forest bio-products, and a series of evening and weekend recreational activities. Participants will develop and utilize new knowledge to address sustainable energy issues impacting society. The REU site program will specifically target recruitment efforts towards women, minorities and students from undergraduate only institutions. Results of the research will be disseminated via campus presentations, and more broadly through journal articles and symposia
REU Site: Explore It! Building the Next Generation of Sustainable Forest Bioproduct Researchers
This three-year REU Site program builds on the substantial research strengths at the University of Maine. The focus on sustainable forest bioproducts is highly topical and of great global importance in the area of sustainable energy alternatives.
Ten US undergraduate participants will conduct research advancing their knowledge of the field in general and one of the thematic elements in detail, specifically:
1) sustainability and life cycle analysis, 2) feedstock extraction/modification, 3) process control and sensing, 4) nanomaterial production and utilization, and 5) new product development. In addition the program includes an international component whereby, six Chilean students on a mutual exchange with six US students will participate in this program.
Ongoing relationships exist between the University of Maine and Chilean faculty in Forest Resources and Engineering disciplines at the University of Chile in Santiago, the University of Bio-Bio in Concepcion, Chile and the University of Concepcion-UDT. The international component will allow students to learn the nuances of technical practices in the forest products industry in Chile, and discuss business, marketing, technology and environmental issues. At the end of the summer, REU student final presentations will be held at the University of Concepcion-UD in the format of a research conference. The entire conference will be streamed to the US so that the U of Maine based research teams can participate. Through participation in this REU Site program students will be better prepared to collaborate with international scholars and will develop a broader international perspective. The REU Site will specifically recruit minorities through extensive use of existing linkages with primarily minority serving institutions. All participants on this award will be non-UMaine students. The involvement of students in exciting research in the area of sustainable energy alternatives enhances the likelihood that they will consider post-graduate study and broaden the base of the Nation\u27s technical manpower. This award is co-funded by the Experimental Program to Stimulate Competitive Research (EHR/EPSCoR
B847: Review of Potential Pasteurization Methods for Apple Cider
The main focus of this paper is to review the pasteurization methods that can be applied to the needs of the apple industry and to recommend further research. In addition to the review of methods, we conducted a sensory evaluation of cider to evaluate the acceptability of various pasteurized samples. This review of potential methods for product treatment will serve as an informative study with recommendations for future processing. Although not an exhaustive survey, conventional methods and the most promising new techniques are discussed.https://digitalcommons.library.umaine.edu/aes_bulletin/1008/thumbnail.jp
TB176: Agrelation: A Computerized Decision-making Tool for Coloraod Potato Beetle Population Management and Environmental Quality Concerns
Many facets of Maine potato production have been simulated with computer models and expert systems. Given the ongoing improvement of computer technology and validation of past efforts, scientists can now combine several agricultural submodels into one holistic and user-friendly computer application. This bulletin reports on the development of one such application—Agrelation—aimed at modeling a portion of Maine potato production and management.https://digitalcommons.library.umaine.edu/aes_techbulletin/1032/thumbnail.jp
TB174: Maine Wild Blueberries Field Winnowing Systems
The objective of this study was to determine if there were differences in berry quality between the two winnowing systems currently used in the Maine wild blueberry industry. The following experiment was performed three times during the 1997 field season.https://digitalcommons.library.umaine.edu/aes_techbulletin/1034/thumbnail.jp

Light-Induced Currents at Domain Walls in Multiferroic BiFeO3.
Multiferroic BiFeO3 (BFO) films with spontaneously formed periodic stripe domains can generate above-gap open circuit voltages under visible light illumination; nevertheless the underlying mechanism behind this intriguing optoelectronic response has not been understood to date. Here, we make contact-free measurements of light-induced currents in epitaxial BFO films via detecting terahertz radiation emanated by these currents, enabling a direct probe of the intrinsic charge separation mechanisms along with quantitative measurements of the current amplitudes and their directions. In the periodic stripe samples, we find that the net photocurrent is dominated by the charge separation across the domain walls, whereas in the monodomain samples the photovoltaic response arises from a bulk shift current associated with the non-centrosymmetry of the crystal. The peak current amplitude driven by the charge separation at the domain walls is found to be 2 orders of magnitude higher than the bulk shift current response, indicating the prominent role of domain walls acting as nanoscale junctions to efficiently separate photogenerated charges in the stripe domain BFO films. These findings show that domain-wall-engineered BFO thin films offer exciting prospects for ferroelectric-based optoelectronics, as well as bias-free strong terahertz emitters
