The students responded more favorably to the solid state model kits, but 80% of students thought that both the model kits and Studio Viewer provided much or great help. “HOW MUCH did each of the following aspects of the class HELP YOUR LEARNING?” On the end of semester SALG in 2016, I asked students about the solid state model kits and Studio Viewer.
These files can be opened on student devices so that students can individually work with 3D models of extended solid state structures. This activity describes how to generate DAE files (3D interchange file format). However, most students have smartphones and tablets. While students can work with the free demo version of CrystalMaker on a computer, most students don’t bring their computers to class. Since there is no lab directly associated with my class, all of our visualization activities are done in a standard lecture room during one or more 50-minute class periods. I believe that it’s important to guide students as they explore 3D extended structures.
static 3D models (generated by CrystalMaker).My experience is that the more representations students can master, the more likely they are to find one that helps them understand solid state structures. I’m interested in any tool that helps my students visualize solids. Science Skills, Practices, and ResourcesĪlthough I’m a solid state chemist, I still find it difficult to teach the visualization of solid state structures.Structure determination of organic and biorganic molecules.The laboratory service usually gives a full data analysis to obtain the main information: small bioorganic structure (aminoacid and peptides).
The instrument is very flexible and can work on different type of solid materials and sample: detector: point detector, linear detector LYNXEYE XE.sample holder: flat plate, wafer chuck, zero background sample holder, rotating capillary, in-vacuum sample holder.Eulerian cradle: x, y, z, Psi, Phi motion.beam type: divergent beam (Bragg-Bentano geometry), linear parallel beam (Goebel mirror), round parallel beam (polycapillary).source: Cu or Cr X-ray tube with fix anode.The main features of this instrument are: The X-ray Powder Diffraction laboratory is equipped with a Bruker D8 DISCOVER diffractometer. This technique is very versatile because can applied on different field of physics chemistry, biology and material science. Email: he X-ray diffraction is the main technique to study the crystalline matter at different level: from finding the phases in an unknown powder to a fine description of the atomic structure of a material.
