The three-way catalytic converter
This extract is concerned primarily with the chemistry that underpins the operation of the three-way catalytic converter that is placed in the exhaust systems of motor vehicles in order to reduce the emissions of primary pollutants: carbon monoxide, oxides of nitrogen and volatile organic compounds, including hydrocarbons. Discussion of the various effects of these pollutants and the consequent introduction and refinement of ‘automotive emission regulations’ has not been included, nor is the
Engaging students, engaging industry and engaging enterprise
This reflective case study and poster relates to a specific event staged by students and examines the phases and critical points within the whole process. It identifies some key learning outcomes for all involved
ICTs: Technology news
To develop as an independent, confident learner you will need to learn the study skills involved in reading articles, taking notes and summarising the information that you have obtained from an article. The unit explores the use of the Web as a resource for keeping up to date, looking in particular at how to assess material available online.
Seeing and Feeling Sound Vibrations
Students examine the existence of sound by listening to and seeing sound waves while conducting a set of simple activities as a class or in pairs at stations. Students describe sound in terms of its pitch, volume and frequency. They use this knowledge to discuss how engineers study sound waves to help people who cannot hear or talk.

Finding information in technology
The internet provides a world of information, but how do you find what you are looking for? This unit will help you discover the meaning of information quality and teach you how to evaluate the material you come across in your study of technology. You will learn how to plan your searches effectively and be able to experiment with some of the key resources in this area.
Introduction to structural integrity
The I-35W bridge collapse in Minneapolis in August 2007, resulting in at least 13 deaths, illustrates the importance of structural integrity. This unit looks at the investigation that followed the collapse of the Silver Bridge over the Ohio River in 1967 which demonstrates how the study of safe design and the assessment of components and structures under load is of increasing importance in engineering design.
Making sense of art history
In this unit you’ll explore art history. Look around you, it’s likely that wherever you are you’ll be able to see some images, it’s also likely that many of these image will be intended to have some sort of effect on you. Here you will be exploring the power of images via a study of contemporary art from the 1980s onwards. Taking the time to look beyond the immediate appearance of an art work to consider what the artist might be trying to say can be immensely rewarding.

Icy bodies: Europa and elsewhere
The new discipline of astrobiology – that is, the science of searching for extraterrestrial life – is not only rapdly growing, but has also captured the public imagination. This unit examines the emergence of icy satellites of distant planets as potential sites of extraterrestrial life. Focussing on the case study of Jupiter's moon Europa, the unit looks at the potential for life there, and speculates on the ethics of searching for life elsewhere in the solar system.
Gene manipulation in plants
Genetic manipulation of crops is an issue of great current interest and controversy. This unit covers some of the basic science that underpins the debate and examines the hotly contested case study of the development of ‘Golden Rice’. By looking at the science 'behind the headlines' you will acquire a clearer idea of both what is possible in GM science and what may be desirable.
The politics of devolution
This unit, which contains material from the current Open University second level Politics course DD203 Power, Equality and Dissent, is pitched at the intermediate level. It should take you about 8 hours to study if you attempt the recommended exercises and make summary notes of its key points. Doing so will allow you to practise the crucial academic skill of summary and précis – extracting the gist of an argument – which will be of particular help if you go on to study in related areas: p

Contributions of Ibn Al-Nafis to the progress of medicine and urology. A study and translations from
This primary-source study of 4 medical works of the 13th century Muslim scholar Ibn Al-Nafis confirmed that his Kitab Al-Mujaz Fi Al-Tibb was authored as an independent book meant to be a handbook for medical students and practitioners not as an epitome of Kitab Al-Qanun of Ibn Sina as thought by recent historians. His huge medical encyclopedia, Al-Shamil, represents a wave of intense scientific activity that spread among the scholars of Cairo and Damascus following the massive destruction of bo
