![]() PLAN FOR DESIGN AND IMPLEMENTATIONA project-based assignment, which incorporates 3D design and printing to create physical and digital representations of minerals at the nanoscale and analyze their reactivity on the environment and humans, will be implemented in GEOL280 – Mineralogy. Goal of the proposal is to use 3-D printing to make the molecular mineral structures accessible to everyone. Since some people do not visualize 3-D data on a notebook or a computer screen, 3-D printing produces tangible objects that are obviously intuitive to students and non-scientists. Integrating 3D printing technology into GEOL280 – Mineralogy is an effective way to connect with students of all learning styles and helps students stay engaged. 3D printing is a transformative technology that has been widely covered in the popular press, resulting in broad public awareness. Students may have difficult time mastering concepts of chemistry and mineralogy becauseĪ) it is typically their first formal encounter with 3-D visualization, and b) the crystal structures may appear to be abstract, and thus overwhelming for many students. Applications to the Earth system that will be addressed include fundamental Earth processes ( e.g., sorption, catalysis, redox, dissolution/precipitation reactions observed on the nanoscale) to applications of highest importance to society ( e.g., energy capture, storage and transfer, water quality, nanopollutants, climate change, human health, transport and fate of engineered nanoparticles in the Earth system).ģD data visualization. This project aims to introduce students to mineral reactivity at the nanoscale and help them to address the “big science questions” related to nanoscience: nanomaterials in the Earth system, impacts on biogeochemical processes, characterization of nanomaterials and their chemical properties at the nanoscale, impacts of natural nanomaterials on the environment and human health. Free ions may sorb onto material surfaces, and this creates problems and opportunities with regard to environmental and health hazards. (2018) observed that the formation, release, environmental transformation, transport, fate and impact of natural, incidental, and anthropogenic nanoparticles impact all components of the Earth system. Mineral nanoparticles commonly behave differently as a function of their size within the nanoscale size range. Minerals are relevant from molecular to planetary dimensions and that they operate from the shortest to the longest time scales over the entire Earth system. Natural crystalline phases such as minerals have always been abundant during Earth’s formation and throughout its evolution over the past 4.54 billion years. Nanoscience is a very rapidly growing frontier area of research that provides abundant opportunities in the Earth and Environmental Sciences. RATIONALE Minerals, environment, and human health. I am planning to use the 3D models developed during the course for future in-class demonstrations and instruction, exhibitions, professional lectures, university workshops, conference presentations, and archives. (2) design and print 3D models of minerals using crystallographic data (3) analyze the impact of minerals on the environment and humans (4) present and discuss the result of their projects to peers and general audience. At the end of the course, students will be able to: (1) recognize common minerals at the nanoscale Goal of the project is to integrate 3D technology in GEOL280 –Mineralogy to effectively teach about the nanoworld ( e.g., atom arrangement in common minerals, sorption, catalysis, redox, dissolution/precipitation reactions observed at the nanoscale) and make “what can’t be seen” tangible. Very few curricula, courses, or even chapters in textbooks (mineralogy, geochemistry, environmental chemistry, etc.) focus on the impact that the shape of minerals at the nanoscale can have on the environment and human health. ![]() These variations are most likely due to differences in the mineral shape at the molecular level. ![]() Minerals are more complex than thought in the past because of the discovery that their chemical properties vary as a function of particle size when smaller than a few nanometers.
