Information about fees and unit costs

Modern methods of physical analysis are an important tool for the physical scientist. This unit provides an introduction to the physical principles and applications in three fields of analysis: X-ray diffraction, analytical electron microscopy and physical spectroscopy. Each of these topics encompasses a variety of measurement techniques. The methodologies presented have wide application in a number of areas of science and technology including nanotechnology and materials research and development. Lectures are supplemented by laboratory practicals to enable students to gain familiarity and experience with the instrumentation.

Rationale

Modern methods of physical analysis are an important tool for the physical scientist. This unit provides an introduction to the physical principles and applications in three fields of analysis: X-ray diffraction, analytical electron microscopy and physical spectroscopy. Each of these topics encompasses a variety of measurement techniques. The methodologies presented have wide application in a number of areas of science and technology including nanotechnology and materials research and development. Lectures are supplemented by laboratory practicals to enable students to gain familiarity and experience with the instrumentation.

Aims

In this unit you will be introduced to a range of techniques used in analysing the physical structure and properties of matter.

Objectives

On completion of this unit you should be able to:

1. Describe and discuss the techniques and applications of X-ray diffraction, electron microscopy and physical spectroscopy.
2. Demonstrate a detailed understanding of the practicalities of these techniques.

Generic attributes:

On completion of this unit you will have developed a range of generic attributes including:

  • Ability to retrieve and evaluate information

  • Ability to think critically and creatively

  • Value truth, accuracy and honesty

  • Ability to work both independently and collaboratively

  • Written and oral communication

  • Technological literacy
  • Content

    In this unit you will be introduced to the theory and practice of important analysis techniques relevant to the materials sciences. Topics covered include:

  • X-ray analysis techniques: Production and properties of X-rays; crystalline nature of materials, lattice planes, crystal systems; X-ray scattering and diffraction; diffractometers and experimental methods.


  • Electron microscopy: Electron-specimen interactions; electron beam instrumentation - transmission and scanning electron microscopes; electron imaging and contrast mechanisms; energy-dispersive X-ray spectrometry - theory and instrumentation; electron diffraction.


  • Spectroscopy: Structure of multi-electron atoms, Hartree theory, periodic table; LS-coupling and jj-coupling, Lande Interval rule, Zeeman and Stark effects; line broadening; molecules, bonding, rotational, vibrational and electronic spectra, Rayleigh and Raman scattering; spectral analysis; spectra from stars, comets, planets, and other space objects and their analysis.
  • Approaches to Teaching and Learning

    In this unit you will attend lectures and practicals to explain and demonstrate the content as described above, supplemented by some written assignments. In addition there will be a number of laboratory sessions during the semester which are intended to provide you with practical experience in the operation of the instrumentation, and in the recording and presentation of data. Together these approaches will lead to an understanding of the scope and limitations involved in the application of the physical analysis techniques presented in this unit.

    Assessment

    You will be required to undertake the following mix of formative and summative assessment. Each assessment instrument will address the stated objectives of the unit.Formative assessment:

    There are ample opportunities during the practical sessions to interact with the staff and receive feedback and advice on the lecture topics, practical reports and assignment questions.
