| Outline and Purpose of the Course | The use of biomaterials is becoming increasingly diverse. Accordingly, it is important to develop a comprehensive and fundamental understanding of the structure, aggregate formation, structural analysis, etc. of biological materials rather than simply following individual events. In this lecture, we learn about analytical methods of molecular structure (nuclear magnetic resonance method, X-ray diffraction method) regarding general biological materials (cellulose, paper, pulp, etc.), and gain knowledge to support structural analysis and processing of biological materials. Cellulose, which is the main component of wood, is explained as a structural analysis example of the biological material. | |||
| Course Goals |
Understand the principles of nuclear magnetic resonance and X-ray diffraction, and their utilization in the analysis method of biomaterials (solid structure). Understand cellulose crystalline polymorphs and solid structures. |

X-ray diffraction method Seventh session: X-ray properties Eighth session: Interaction between X-rays and substances Ninth session: X-ray interventions and regressions (one electronic, one nuclear, scattering from crystals, and structural factors) Tenth session: Bragg and Laue conditions Eleventh session: Crystals (unit lattices, crystal systems, plane indices, point groups, target elements, Bravais lattices) Twelfth session: Reciprocal lattices, reflecting spheres, limiting spheres Thirteenth session: Fiber diagrams, crystal structure analysis III. Solid cellulose structures Fourteenth session: Polymorphism, physical properties Term-end examination/learning achievement evaluation Fifteenth session: Feedback During feedback time, there will be an explanation of answers to the regular examination and replies to questions from students in the classroom. |
