Dissemination of IT for the Promotion of Materials Science (DoITPoMS)

DoITPoMS TLP Library

TLP Library

Teaching and learning packages (TLPs) are self-contained, interactive resources, each focusing on one area of Materials Science.

TLPs containing HTML5 animations/simulations are labelled with the tag . We have found that often the HTML5 animations render better in Microsoft Edge, so if your favourite browser does not work very well with them, please try an alternative.

Additive Manufacturing

This TLP provides an introduction to additive manufacturing methods, their advantages and limitations, and how the properties of printed objects are affected by varying printing parameters.

Atomic Force Microscopy

Provides a brief introduction to atomic force microscopy (AFM), some of the ways it is commonly used and some of the problems faced.

Crystallinity in Polymers

An understanding of polymer crystallinity is important because the mechanical properties of crystalline polymers are different from those of amorphous polymers. Polymer crystals are much stiffer and stronger than amorphous regions of polymer.

Diffraction and Imaging

A brief summary of diffraction and imaging using an optical system.

Elasticity in Biological Materials

This teaching and learning package (TLP) discusses the elasticity of biological materials. Whilst some show Hookean elasticity, the vast majority do not. Non-linear elasticity is considered, in particular J-shaped and S-shaped curves. Viscoelasticity is also discussed, using hair and spiders' silk as examples.

Examination of a Manufactured Article

This TLP provides an introduction to the deconstruction and investigation of the materials and processes used in an everyday item or article.

The Glass Transition in Polymers

This teaching and learning package is based on a lecture demonstrations used within the Department of Materials Science and Metallurgy at the University of Cambridge. The package is aimed at first year undergraduate Materials Science students and focuses on the glass transition in polymers.

Indexing Electron Diffraction Patterns

An introduction to the indexing of diffraction patterns.

Liquid Crystals

This Teaching and Learning Package provides an introduction to liquid crystals, their physical properties and their modern-day applications.

Microstructural Examination

This teaching and learning package (TLP) looks at how what we see in micrographs relates to equilibrium phase diagrams and cooling routes for alloy systems.

Optical Microscopy

An introduction to the use of optical microscopes. It introduces the different types of microscope used to examine specimens and how to set them up correctly. There is also an introduction to specimen preparation.

Introduction To Photoelasticity

This tutorial is based on lab work within the Department of Materials Science and Metallurgy at the University of Cambridge. The tutorial provides an introduction to the topic of photoelasticity and preparation for lab work. Photographs illustrate many features of birefringence in polymers under polarised light.

Polymer Basics

This teaching and learning package is an introduction to the basic concepts of polymer science. It includes molecular structure, synthesis and tests for identification.

The Stiffness of Rubber

This teaching and learning package is based on two experiments which demonstrate the behaviour of rubber under tension. The first displays the unusual behaviour of a rubber strip when heated under tension; the second considers the behaviour of a rubber membrane under tension. In both cases the behaviour is considered theoretically in terms of the molecular structure of rubber and the thermodynamic entropy changes involved.

Transmission Electron Microscopy

Transmission electron microscopy is a very important tool in materials science for investigating the fine-scale structure of materials. This TLP serves as an introduction to the basic concepts and structure of the transmission electron microscope.
