Transcription

1 (Revised) Course Code and Title Course Coordinator Details of Course MS731M: Chemical Analysis of Materials Dr. Eileen Fong (Course Coordinator) Dr. Thresen Matthew Rationale for introducing this course This course will cover the subject of chemical analysis of materials. Chemical analysis of materials is wherein the composition and chemical information of various materials and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained. This course will focus specifically on different spectroscopic and spectrometric analytical techniques for chemical analysis of materials It will cover surface chemical analysis to bulk chemical analysis of materials. Aims and objectives At the end of this course the students will be able to Describe the working principles of UV-VIS, IR, XRF, XPS and MS, Analyse data acquired from each of the analytical techniques Recommend suitable techniques for evaluating material properties with clear justifications. Integrate information from multiple datasets to make deductions about material properties Course Syllabus Refer to page 3 to 5 Assessment (Individual Assessment) Assessment Points 7 Mode of Assessments and weighting 3 x Tutorials CA1: MCQs CA2: MCQs CA3: Final Quiz (Written) Research paper critique: peer review 15% 25% 100% 1
