The present invention includes methods of promoting single crystal growth via solid-solid transformation of an appropriate glass, while avoiding the gaseous or liquid phase. In certain embodiments, in the all-solid-state glass-to-crystal transformation of the invention, extraneous nucleation is avoided relative to crystal growth via spatially localized laser heating and optional inclusion of a suitable glass former in the composition. The ability to fabricate patterned single-crystal architecture on a glass surface was demonstrated, providing a new class of micro-structured substrate for low cost epitaxial growth and active planar devices, for example.

Peatlands contain a large belowground carbon (C) stock in the biosphere, and their dynamics have important implications for the global carbon cycle. However, there are still large uncertainties in C stock estimates and poor understanding of C dynamics across timescales. Here I review different approaches and associated uncertainties of C stock estimates in the literature, and on the basis of the literature review my best estimate of C stocks and uncertainty is 500 ± 100 (approximate range) gigatons of C (Gt C) in northern peatlands. The greatest source of uncertainty for all the approaches is the lack or insufficient representation of data, including depth, bulk density and carbon accumulation data, especially from the world's large peatlands. Several ways to improve estimates of peat carbon stocks are also discussed in this paper, including the estimates of C stocks by regions and further utilizations of widely available basal peat ages. Changes in peatland carbon stocks over time, estimated using Sphagnum (peat moss) spore data and down-core peat accumulation records, show different patterns during the Holocene, and I argue that spore-based approach underestimates the abundance of peatlands in their early histories. Considering long-term peat decomposition using peat accumulation data allows estimates of net carbon sequestration rates by peatlands, or net (ecosystem) carbon balance (NECB), which indicates more than half of peat carbon (> 270 Gt C) was sequestrated before 7000 yr ago during the Holocene. Contemporary carbon flux studies at 5 peatland sites show much larger NECB during the last decade (32 ± 7.8 (S.E.) g C m-2 yr–1) than during the last 7000 yr (∼ 11 g C m-2 yr–1), as modeled from peat records across northern peatlands. This discrepancy highlights the urgent need for carbon accumulation data and process understanding, especially at decadal and centennial timescales, that would bridge current knowledge gaps and facilitate comparisons of NECB across all timescales. © 2012 Author(s).

The Natural Hazards Engineering Research Infrastructure (NHERI) will be supported by the National Science Foundation (NSF) as a distributed, multi-user national facility that will provide the natural hazards research community with access to research infrastructure that will include earthquake and wind engineering experimental facilities, cyberinfrastructure, computational modeling and simulation tools, and research data, as well as education and community outreach activities. NHERI will be comprised of separate awards for a Network Coordination Office, Cyberinfrastructure, Computational Modeling and Simulation Center, and Experimental Facilities, including a post-disaster, rapid response research facility. Awards made for NHERI will contribute to NSFs role in the National Earthquake Hazards Reduction Program (NEHRP) and the National Windstorm Impact Reduction Program. NHERI continues NSFs emphasis on earthquake engineering research infrastructure previously supported under the George E. Brown, Jr. Network for Earthquake Engineering Simulation as part of NEHRP, but now broadens that support to include wind engineering research infrastructure. NHERI has the broad goal of supporting research that will improve the resilience and sustainability of civil infrastructure, such as buildings and other structures, underground structures, levees, and critical lifelines, against the natural hazards of earthquakes and windstorms, in order to reduce loss of life, damage, and economic loss. Information about NHERI resources will be available on the DesignSafe-ci.org web portal.

NHERI Experimental Facilities will provide access to their experimental resources, user services, and data management infrastructure for NSF-supported research and education awards. This award will provide a NHERI Experimental Facility at Lehigh University to support research to mitigate the impact of natural hazards, including earthquakes, on structures. This facility will provide experimental resources for accurate, large-scale, multi-directional simulations to investigate the effects of natural hazard events on civil infrastructure systems, with potential soil-foundation effects. The new discoveries and knowledge from these simulations will enable researchers to develop and validate new hazard mitigation solutions and innovative hazard-resistant structural concepts. The research conducted by facility users will contribute to the development of the next generation workforce for natural hazards engineering research, educational activities, and professional practice. The education and community outreach programs, along with the strategic education partnerships of the facility, will target a diverse audience and attract young individuals into science, technology, and engineering, while also reaching out to educate and inform a broader community. This facility will conduct annual workshops for prospective users and will host Research Experiences for Undergraduate students.

The facilitys experimental resources, which include a strong floor, multi-directional reaction wall, static and dynamic actuators, and testing algorithms, will support large-scale, multi-direction, real-time hybrid simulations that combine physical experiments with computer-based simulations for evaluating performance of large-scale components and systems. The types of laboratory simulations and tests enabled by the facility include: (1) hybrid simulation (HS), which combines large-scale physical models with computer-based numerical simulation models; (2) geographically distributed hybrid simulation (DHS), which is a HS with physical models and/or numerical simulation models located at different sites; (3) real-time hybrid earthquake simulation (RTHS), which is a HS conducted at the actual time scale of the physical models; (4) geographically distributed, real-time hybrid earthquake simulation, which combines DHS and RTHS; (5) dynamic testing, which loads large-scale physical models at real-time scales through predefined load histories; and (6) quasi-static testing, which loads large-scale physical models at slow rates through predefined load histories. The facility resources will enable multiple, large-scale simulations and tests to be conducted simultaneously, allowing numerous users to work concurrently without significant interruption. The large-scale hybrid simulations are a unique resource for system-level response data, since they enable the definition of the system to be expanded well beyond the size of typical laboratory physical models. At the same time, due to its large size, the facility can accommodate large-scale physical models, which reduces scaling effects associated with typical, small physical models. A broad array of instrumentation, large-scale data acquisition systems, and advanced sensors will provide the system-level data needed for advancing computational modeling and simulation. The facility will utilize the HS capabilities for earthquake engineering to develop hybrid wind engineering simulation capabilities within the facility. The HS being advanced at the facility has the potential for broader impacts in other fields of science and engineering, where combining physical models and numerical simulation models will enable more holistic definitions of the system in experimental research.

Agency: NSF | Branch: Standard Grant | Program: | Phase: ITEST | Award Amount: 1.20M | Year: 2016

This project will advance efforts of the innovative Technology Experiences for Students and Teachers (ITEST) program to better understand and promote practices that increase students motivations and capacities to pursue careers in fields of science, technology, engineering, or mathematics (STEM) by producing empirical findings and/or research tools that contribute to knowledge about which models and interventions with K-12 students and teachers are most likely to increase capacity in the STEM and STEM-cognate intensive workforce of the future.

This project will develop, implement, and evaluate a series of innovative socio-environmental science investigations (SESI) using a geospatial curriculum approach with STEM-related mentoring that will provide economically disadvantaged students in the 9th grade of the Building 21 school in Allentown, PA with technology-rich geospatial learning experiences to develop STEM-related skills. The project will focus on social issues related to environmental science. This project uses a design partnership among Lehigh University natural science professors, social science professors, education professors, the STEM Valley Mentoring Coalition, Building 21 science and social studies school teachers, the Allentown city government, and PPL Corporation to develop geospatial investigations with Web GIS (Geospatial Information Systems) that will prepare students with skills, and career awareness, to motivate them to pursue appropriate education pathways for STEM-related occupations.

Despite the accelerating growth in geospatial industries and congruence across STEM, few school-based programs integrate geospatial technology within their curriculum, and even fewer incorporate STEM-related mentoring to promote interests and aspirations in related occupations. The project will contribute to educational research infrastructure by producing a series of instruments to measure the development of STEM-related skills in the context of SESI investigations, students perceptions of mentoring experience, STEM career motivation, and STEM interest for use with high school students who are traditionally underrepresented in STEM-related disciplines and careers. The project also promotes a unique community-based partnership with university scientists, social scientists, educators, a science center, and STEM mentors that involve high school students in the research and decision-making process about local environmental problems. The learning activities will provide opportunities for students to collaborate, seek evidence, problem-solve, master technology, develop geospatial thinking and reasoning skills, and practice communication skills that are essential for the STEM workplace. The project will enable researchers to (1) examine how SESI and mentoring increases students interest in STEM and their motivation to pursue STEM-related careers, and (2) analyze how the geospatial curriculum approach when combined with STEM-related mentoring can improve STEM-related skills with students under-represented in STEM.
