ABSTRACT Materials science skills and knowledge, as an addition to the traditional curricula for physics and chemistry students, can be highly valuable for transition to graduate study or other career paths in materials science. The chemistry and physics departments at Weber State University (WSU) are harnessing an interdisciplinary approach to materials science undergraduate research. These lecture and laboratory courses, and capstone experiences are, by design, complementary and can be taken independently of one another and avoid unnecessary overlap or repetition. Specifically, we have a senior level materials theory course and a separate materials characterization laboratory course in the physics department, and a new lecture/laboratory course in the chemistry department. The chemistry laboratory experience emphasizes synthesis, while the physics lab course is focused on characterization techniques. Interdisciplinary research projects are available for students in both departments at the introductory or senior level. Using perovskite materials for solar cells, WSU is providing a framework of different perspectives in materials: making materials, the micro- and macrostructure of materials, and the interplay between materials to create working electronic devices. Metal-halide perovskites, a cutting-edge technology in the solar industry, allow WSU to showcase that undergraduate research can be relevant and important. The perovskite materials are made in the chemistry department and characterized in the physics department. The students involved directly organize the collaborative exchange of samples and data, working together to design experiments building ownership over the project and its outcomes. We will discuss the suite of options available to WSU students, how we have designed these curricula and research, as well as some results from students who have gone through the programs.

Synthesis and Characterization of Superparamagnetic Iron Oxide Nanoparticles: A Series of Laboratory Experiments
The following laboratory procedure provides students with hands-on experience in nanomaterial chemistry and characterization. This three-day protocol is easy to follow for undergraduates with basic chemistry or materials science backgrounds and is suitable for inclusion in upper-division courses in inorganic chemistry or materials science. Students use air-free chemistry procedures to synthesize and separate iron oxide magnetic nanoparticles and subsequently modify the nanoparticle surface by using a chemical stripping agent. The morphology and chemical composition of the nanoparticles are characterized using electron microscopy and dynamic light scattering measurements. Additionally, magnetic characterization of the particles is performed using an inexpensive open-source (3D-printed) magnetophotometer. Possible modifications to the synthesis procedure, including the incorporation of dopants to modify the magnetic response and alternative characterization techniques, are discussed. The three-day synthesis, purification, and characterization laboratory will prepare students with crucial skills for advanced technology industries such as semiconductor manufacturing, nanomedicine, and green chemistry.

The addition of research-focused experiences to undergraduate chemistry laboratory courses has been shown to bolster student learning, enhance student retention in STEM, and improve student self-identity as scientists. In the area of synthetic organic chemistry, the preparation of libraries of compounds with novel optical and electronic properties can provide a natural motivational goal for research-focused exercises that can be undertaken by individual students or collectively as a class. However, integrating such experiences into a community college teaching laboratory setting can face challenges imposed by the cost of supplies, limited laboratory space, and access to characterization facilities. To address these challenges, we have devised a sequence of inquiry-driven, research-focused laboratory exercises that can be readily integrated into an organic chemistry laboratory course with minimal cost. This sequence consists of a multistep synthesis of perylenediimide dyes that introduces students to advanced synthetic techniques, such as organometallic coupling reactions, column purification, and reactions performed under inert atmosphere. This high-yield, three-part synthesis can be easily varied by individual students or small groups within a class to form a broad library of compounds with potential utility for applications in light harvesting, molecular electronics, catalysis, and medicine. We describe the design of low-cost workstations for chemical synthesis under inert atmosphere and provide auxiliary lesson plans that can be used to expand the scope of a laboratory course beyond synthetic organic chemistry by introducing students to concepts in molecular spectroscopy.more » « less

Abstract Considering the growing interest in magnetic materials for unconventional computing, data storage, and sensor applications, there is active research not only on material synthesis but also characterisation of their properties. In addition to structural and integral magnetic characterisations, imaging of magnetisation patterns, current distributions and magnetic fields at nano- and microscale is of major importance to understand the material responses and qualify them for specific applications. In this roadmap, we aim to cover a broad portfolio of techniques to perform nano- and microscale magnetic imaging using superconducting quantum interference devices, spin centre and Hall effect magnetometries, scanning probe microscopies, x-ray- and electron-based methods as well as magnetooptics and nanoscale magnetic resonance imaging. The roadmap is aimed as a single access point of information for experts in the field as well as the young generation of students outlining prospects of the development of magnetic imaging technologies for the upcoming decade with a focus on physics, materials science, and chemistry of planar, three-dimensional and geometrically curved objects of different material classes including two-dimensional materials, complex oxides, semi-metals, multiferroics, skyrmions, antiferromagnets, frustrated magnets, magnetic molecules/nanoparticles, ionic conductors, superconductors, spintronic and spinorbitronic materials.more » « less

Hydrogels are soft water-rich materials with physical properties that can be easily tuned by modifying their network structure. For instance, increasing or decreasing the cross-linking density has a profound effect on their water absorption capabilities and mechanical strength. These physical changes are showcased in a new experiment for organic chemistry and polymer science teaching laboratories based on the practical green synthesis and characterization of lactose methacrylate derived hydrogels. Lactose, a disaccharide derived from dairy waste byproducts, is functionalized with photoreactive methacrylate groups using methacrylic anhydride. The resulting mixture is subsequently photoirradiated to generate a cross-linked hydrogel. Structure–property relationships are assessed through comparative studies of three hydrogels of varying compositions. Compression tests and swelling studies in different aqueous environments offer a guided-inquiry experience. Students determine a relationship between cross-linking density and the physical properties of the hydrogels. This experiment highlights the valorization of biomass and multiple green chemistry principles including use of renewable feedstocks, atom economy, energy efficiency, waste prevention, and water as a benign solvent. Learning outcomes for an organic chemistry laboratory course include introduction to disaccharide and cross-linked polymer structures, observable physical change dependency with cross-linking density, and laboratory methods for evaluating water absorption capacities. Objectives aligned with a polymer course are incorporating mechanical compression instrumentation, mechanistic understanding of light-induced free radical polymerizations, and an appreciation for the application of hydrogels to commercial products. Overall, the translation of a current literature publication to an inexpensive and versatile experiment engages students in a modern example of sustainable polymer chemistry.more » « less

Production and Characterization of Graphene and Other 2-dimensional Nanomaterials: An AP High School Inquiry Lab (Curriculum Exchange)According to the National Nanotechnology Initiative, nanoscience and nanotechnology areexpected to play key roles in developing solutions to some of our greatest global engineeringchallenges in energy, medicine, security, and scientific discovery. There is high expectation thatdevelopments in nanotechnology will lead to new job creation and become an economic driverwith new direction for research and development coming from nano-enabled products. In light ofthe potential economic and national security implications, it is imperative that we support thedevelopment of the next generation of the high school curriculum as a way to motivate studentstowards pursuing education and careers in nanotechnology. Recent advances in nanomaterialsprocessing, particularly 2-dimensional nanomaterials synthesis, present the opportunity tointegrate nanotechnology curriculum into high schools in safe and relatively inexpensivemanners. The multifunctional characteristics of 2-dimensional nanomaterials make themattractive for printable and flexible electronics, nanostructured thermoelectrics, photovoltaics,batteries, and biological and chemical sensors. Thus, 2-dimensional nanomaterials provide anideal context for high school students to investigate the principles of nanoscience andnanotechnology. In our work, we present an Advanced Placement (AP) Chemistry Inquiry Laboratory (CIL),which is being implemented at Centennial High School in Meridian, Idaho. The CIL is aligned toNational College Board requirements for AP Chemistry courses as well as Next GenerationScience Standards. The laboratory is designed to encompass approximately five hours of time,including teacher preparation time, pre-laboratory activities, materials synthesis andcharacterization, and a field trip to a local industry partner for scanning electron microscopyanalysis of the resultant nanomaterials. Students are organized into small groups under thecontext that they are working to produce and characterize nanomaterials as part of an industryresearch team. To synthesis the 2-dimensional nanomaterials, students use cosolvent exfoliationof layered materials such as graphite, MoS2, WS2, and hBN. The students must then use opticalspectroscopy and electrical characterization techniques to determine if their material is aconductor, semiconductor, or an insulator. The students then use scanning electron microscopyto image the morphology of the 2-dimensional nanoflakes they produced, which exposes thestudents to advanced nanoscale characterization techniques.more » « less
