Hope College is a private, residential liberal arts college located in downtown Holland, Michigan, United States, a few miles from Lake Michigan. It was opened in 1851 as the Pioneer School by Dutch immigrants four years after the community was first settled. The first freshman college class matriculated in 1862, and Hope received its state charter in 1866. Historically associated with the Reformed Church in America, it retains a conservative Christian atmosphere. The school's campus—now 125 acres , adjacent to the downtown commercial district—has been shared with Western Theological Seminary since 1884. The school has about 3,350 undergraduates. John C. Knapp assumed office as 12th President on July 1, 2013. Wikipedia.

The current study investigates whether and how Facebook increases college-age users' subjective well-being by focusing on the number of Facebook friends and self-presentation strategies (positive vs. honest). A structural equation modeling analysis of cross-sectional survey data of college student Facebook users (N=391) revealed that the number of Facebook friends had a positive association with subjective well-being, but this association was not mediated by perceived social support. Additionally, we found that there was a negative curvilinear (inverted U-shape curve) relationship between Facebook friends and perceived social support. As for self-presentation strategies, whereas positive self-presentation had a direct effect on subjective well-being, honest self-presentation had a significant indirect effect on subjective well-being through perceived social support. Our study suggests that the number of Facebook friends and positive self-presentation may enhance users' subjective well-being, but this portion of happiness may not be grounded in perceived social support. On the other hand, honest self-presentation may enhance happiness rooted in social support provided by Facebook friends. Implications of our findings are discussed in light of affirmation of self-worth, time and effort required for building and maintaining friendships, and the important role played by self-disclosure in signaling one's need for social support. © Copyright 2011, Mary Ann Liebert, Inc.

It is a well-known fact that light, stable nuclei, those with which we are most familiar, are made up of roughly equal numbers of protons and neutrons. This project will explore the structure of neutron-rich nuclei that are far from stability and consequently much less familiar. This will provide a vital understanding of the subtleties of the nuclear force in nuclei that can be found in explosive astrophysical environments, such as a supernova. These experiments will help us to understand the different abundances of the observed elements in the universe, in addition to engaging students in the study of these fundamental questions. In addition, the applied nuclear physics efforts at Hope College will use traditional accelerator techniques for the rapid testing of consumer goods and environmental samples containing chemicals of concern. Work on non-destructive characterization of automotive paint samples for forensic applications will continue.
Experiments producing unstable nuclei at the National Superconducting Cyclotron Lab (NSCL) (excited states of helium-9 and oxygen-26) will measure decay neutrons with the Modular Neutron Array, while emitted charged fragments are deflected with a high-field dipole magnet into timing and energy detectors. The properties of the decaying nucleus will be determined with invariant mass spectroscopy. Astrophysics measurements will also be done at the NSCL with the Summing NaI Detector supplemented with an internal beta detector or an internal gas cell constructed at Hope College. The interdisciplinary applied physics portion of the proposed research, done with the Hope accelerator, is principally based on particle induced gamma-ray emission, particle induced x-ray emission, and Rutherford backscattering spectroscopy.

Recognizing the national need for significant improvement in undergraduate STEM education, collaborators from six institutions (Rochester Institute of Technology, St. Marys University, Oral Roberts University, Hope College, Ursinus College, and California Polytechnic University) will explore a new approach to introduce students to authentic research in biochemistry laboratory courses. The project will test the hypotheses that engaging in authentic research will improve students abilities to master key aspects of experimentation (experimental design, data processing and interpretation, and communication of research outcomes) and visualization (use of representations to communicate various aspects of the research process). The project is likely to be transferrable to other institutions, and is an example of a cost-effective way to introduce course-based research into the undergraduate curriculum.
Biochemistry laboratory courses will be redesigned to include modules in which students will integrate computational and wet lab techniques as they characterize proteins whose three dimensional structures are known but to which functions have not been previously ascribed. Because the project is focused on discovery, it is reasonable to expect that some of the students will produce novel results that will contribute to the field of biochemistry. Formative and summative evaluation will address assessment of student learning gains in terms of improved conceptual understanding and visualization of experiments using a validated instrument composed of open-ended and closed-ended questions. Faculty members and teaching assistants will be surveyed and interviewed about their satisfaction with the project, its usability, and the extent to which they see the project as part of their own and their students development. The project team will create and disseminate modules (promol.org) that form the core of a new curriculum for undergraduate biochemistry laboratory courses. The results of the work will be presented at professional meetings, such as the American Society of Biochemistry and Molecular Biology, and submitted to scholarly journals.

A variety of energy storage materials will be essential in years to come as alternative energy sources become an increasing part of the worlds energy portfolio. Stable, high-capacity, efficient, and inexpensive battery materials are needed, but no one type of storage solution will the best for every type of application. The focus of this research program is to study a class of compounds called metal hexacyanoferrates (HCFs), which show promise as battery materials. HCFs consist of more earth-abundant elements, which will decrease the cost for future device implementations, and because of their open crystal structure, they have increased stability over many charge-discharge cycles. With support from the Metals and Metallic Nanostructures program of the Division of Materials Research, Associate Professor of Physics Jennifer Hampton and a team of undergraduate students at Hope College will fabricate HCF thin films using electrochemical methods. They will quantify the effects of both composition and structure on the energy storage properties of the resulting materials. By doing so, they will increase our understanding of these HCF films, opening up a broader range of materials available for use in advanced battery technologies. This interdisciplinary research program will involve undergraduate students with interests in physics, chemistry, and materials engineering. The students will contribute to research at the boundaries between the different disciplines and will receive training in a significant area of new science which will be broadly applicable to a variety of careers in the modern workforce.
Open-framework intercalation compounds such as metal hexacyanoferrates (HCFs) have gained increasing interest as materials for energy storage applications. The goal of this research program is to characterize HCF films made by electrochemically modifying metal thin film substrates. Associate Professor of Physics Jennifer Hampton and a team of undergraduate students at Hope College will fabricate HCF films and characterize their charge storage and charge transport properties. Specifically, by taking advantage of the wide array of deposition and post-processing techniques available with electrochemistry, starting materials with varying metal composition and deliberately controlled microstructure will be produced for the subsequent HCF formation step. By quantifying the effects of both composition and structure on the resulting charge storage properties of the HCF films, the team will advance the fundamental knowledge of charge transport in this class of open-framework intercalation compounds and will assist in the development of advanced battery technologies for specific applications. Additionally, a new laboratory unit on AC electrochemical analysis will be developed for use in an upper-level physics laboratory course at Hope College, strengthening the connections between current research and education in the context of an undergraduate institution. This work is funded by the Metals and Metallic Nanostructures program of the Division of Materials Research.

RUI: Enabling Rational Design of Smart Interfaces Incorporating Metal-Organic Coordinated Assemblies (CHE-1508244)
Mary E. Anderson, Hope College
Metal-organic frameworks (MOFs) are crystalline, porous materials with extremely high surface areas that exhibit great potential for chemical sensing, reaction catalysis, and gas storage. For many of these applications, the incorporation of MOF thin films grown directly on supporting materials is required. To effectively fabricate devices with smart interfaces that harness the properties of these MOF materials, it is crucial to understand the fundamentals of film formation. This research systematically investigates thin film MOF growth and develops design rules for low-energy processing techniques on a variety of technologically-relevant substrates. These design rules, for tailoring film structure and composition, are utilized 1) to tune the optical, electrical, and mechanical properties of the film and 2) to develop fabrication techniques that integrate MOF thin films into cutting-edge technologies for chemical sensing and harvesting solar energy. Undergraduate students are actively engaged in all aspects of the research, providing them with experience in the interdisciplinary areas of materials chemistry, surface science, and modern analytical instrumentation.
With this award the Macromolecular, Supramolecular and Nanchemistry Program of the NSF Chemistry Division supports the research of Dr. Anderson at Hope College to investigate the formation of surface-anchored metal-organic frameworks (SurMOF) for integration directly into device architectures for chemical sensing and photonic applications. Film formation is studied for different systems with incrementally increasing complexity (i.e. HKUST-1, MOF-14, MOF-5, IRMOF-3). Effects of deposition variables such as temperature, time, and deposition methods (i.e. layer-by-layer, co-deposition, seeded deposition) are investigated. Studies are extended to understand deposition on different substrates of technological relevance, such as oxide materials (i.e. SiO2, ITO, Al2O3) and flexible polymeric materials. Rational design rules for growth initiation as well as inhibition are determined. Scanning probe microscopy (SPM) and surface-specific spectroscopies (i.e. ellipsometry, FT-IR) are used to characterize SurMOF film growth to determine the effect of deposition conditions with particular focus on foundational layers forming at the substrate-film interface. Mechanical, electrical, and optical properties of films are evaluated using advanced SPM modes (i.e. quantitative nanomechanical mapping, conductive probe), electrochemistry (i.e. cyclic voltammetry, chronocoulometry), and spectroelectrochemical characterization. By following developed design rules, understanding material properties, and employing membrane-templating techniques, this research integrates SurMOF films as smart interfaces into test-bed structures fabricated for chemical sensing and solar energy harvesting.
