This module is not approved as a discovery module

Objectives

This module introduces advanced features of the structures and physical properties of inorganic and metal/organic solids. It builds on structural chemistry introduced at Levels 1 and 2. The synthesis of extended solids, their band structures, and the conductivity, magnetic and luminescence properties they can show, are also discussed.

Applications of these phenomena to nanotechnology are presented.

Learning outcomes
Students will:
- Be able to recognise, describe and draw common inorganic structure types, and understand their thermodynamics (lectures 1-4, tutorial 1)
- Be familiar with common synthesis methods of inorganic solids
- Be aware of analytical methods available to characterise inorganic solids
- Understand the electronic structures of extended solids, and how these give rise to (super)conductivity and bulk magnetism (lectures 6-16, tutorial 2)
- Appreciate current methods for fabricating materials on the micro and nano scale, and the unique properties that can result (lectures 17-21, examples class).

Coursework problem-solving will develop writing and numeracy skills, and will require some on-line independent study.

Syllabus

Structures of Inorganic Solids (FCM)
- Close packing and close-packed structures. Thermodynamics of solid lattices (lattice energies, Madelung constants)
- Structures of ionic compounds. Simple ionic salt structures, interstitial sites and radius ratios. Polymorphism.
- More complicated structure types. Spinels, perovskites, rutile etc.
- Structure prediction - Pauling's Rules

Synthesis and Characterisation(FCM)
- Synthesis of solid state materials, including thermal and microwave pyrolysis, chemie douce, chemical vapour deposition, hydrothermal synthesis
- Methods for studying inorganic structures. Diffraction techniques, X-ray and electron spectroscopy including EXAFS and XPS, electron microscopy, atomic probe microscopies, other spectroscopic techniques.

Defects in Solids (FCM)
- Vacancies and structure defects (redox-induced and interstitial sites).
- Detection of defects
- Migration of ions through solids. Ionic and superionic conductivity

Physical Properties of Inorganic Solids (MAH)
- Band structures of metals and other materials. Conductors, semiconductors and insulators. Surface corrosion of metals
- Conductivity and superconductivity. Ion vs. electron conductors. Doped molecule-based conductors (dithiolenes, polymeric SN and polyacetylene as examples).
- Designs and types of batteries, fuel cells and nano devices.
Copper oxide superconductors, and giant magnetoresistance in manganese oxide materials. Mechanisms of both phenomena.
- Luminescence in extended solids.
- Magnetism. Diamagnetism vs. paramagnetism, and how we measure it. How spins interact in dimers and selected larger molecules.
Magnetism in polymeric materials. Band structures of states in 1-D, 2-D and 3-D materials. Bulk ordering phenomena.
- Functional molecule-based materials. Single molecule magnets, spin-crossover switches.

Films and Particles of Inorganic Materials (DZ)
- Introduction to nanoscience and technology and the unique optical/ electronic properties. Principles of scanning probe microscopy (AFM, STM and SICM) based surgace patterning and characterisation techniques for nanomaterials.
- Quantum dots, metal nanoparticles and metal clusters. Syntheses, characterisation and size dependant electronic (badn-gap) structures, and their unique size-dependant fluorescence and absorption properties.
- Nanoparticle surface engineering and bioconjugation techniques. Development of multifunctional nano- bioconjugation for biomedical applications, such as ultra-sensitive biosensing, disease diagnosis, targeted bioimaging and cancer therapeutics.

Private study

Tutorials and the examination may ask you to apply principles learnt during the module to compounds not directly covered in lectures. Further reading from recommended texts, and/or the WWW, is therefore strongly encouraged.

The above list assumes 3 hours of reading per lecture. The critical literature review in the second tutorial will require additional reading from the primary chemical literature, available in the Edward Boyle library or on-line.

Opportunities for Formative Feedback

Two (assessed) tutorials will be held with inorganic chemistry staff, in weeks 5 and 8 of semester 2. These will monitor progress in MJH and MAH's parts of the module, respectively.

Support for DZ's material in the last part of the module will be provided through an examples class in the final week of the semester.
