The 24th Leeds-Lyon Symposium was held in London from 4th-6th September 1997, where it was hosted by the Imperial College of Science, Technology and Medicine.

The meeting addressed the topic of "Tribology for Energy Conservation" and attracted a wide range of stimulating papers and speakers. Some 150 delegates from nineteen countries attended and about sixty papers were presented in fifteen sessions. These covered the topics of lubricants, wear, friction reduction, hydrodynamics, elastohydrodynamic lubrication, surface roughness, manufacturing, component life (including condition monitoring), and automotive aspects.

These papers represent the proceedings from the 29th Leeds-Lyon Symposium on Tribology, 'Tribological Research and Design for Engineering Systems' which was held in September 2002. Over 130 delegates from 18 countries attended the symposium, and the extensive discussions generated over 150 written questions and responses, which are documented at the end of this proceedings volume.
There have been many advances in the field of tribology in recent years, with progress being made in the engineering and interaction of surfaces; micro and nano-tribology; elastohydrodynamics; surface films; surface texture; tribochemistry; wear and life prediction; with both experimental and theoretical contributions. These advances were reviewed, and the impact of this understanding on the fundamentals upon total engineering activity in design, manufacture and machine operation were considered.

Scientists and researchers in the field of tribology.

The objective of the 28th Leeds-Lyon Symposium on Tribology was to define current understanding of the science relating to boundary and mixed lubrication and to compare this with the needs of industry in terms of applications.

Major advances have been made in recent years in areas such as contact mechanics, wear, elastohydrodynamic lubrication incorporating surface texture, lubricant interactions with surfaces and the experimental interrogation of surface topography, surface films and lubricant film thickness. However, the needs of industry are equally intense with a seemingly relentless drive towards more compact, efficient and durable tribological systems.

"Boundary and Mixed Lubrication: Science and Applications" publishes peer-reviewed papers presented at the 28th Leeds-Lyon Symposium on Tribology. The Keynote address was presented by Professor Koji Kato, Tohoku University, Sendai, Japan under the title "Wear of Boundary or Mixed Lubrication Regimes," which set the scene for the meeting with a review of recent scientific developments with a clear focus on the potential for technological and industrial development.

This collection of fully peer-reviewed papers were presented at the 26th Leeds-Lyon Tribology Symposium which was held in Leeds, UK, 14-17 September, 1999.
The Leeds-Lyon Symposia on Tribology were launched in 1974, and the large number of references to original work published in the Proceedings over many years confirms the quality of the published papers. It also indicates that the volumes have served their purpose and become a recognised feature of the tribological literature.
This year's title is 'Thinning Films and Tribological Interfaces', and the papers cover practical applications of tribological solutions in a wide range of situations.
The evolution of a full peer review process has been evident for a number of years. An important feature of the Leeds-Lyon Symposia is the presentation of current research findings. This remains an essential feature of the meetings, but for the 26th Symposium authors were invited to submit their papers for review a few weeks in advance of the Symposium. This provided an opportunity to discuss recommendations for modifications with the authors.

A revised and updated edition of Professor Duncan Dowson's classic "History of Tribology" which has been unavailable for a number of years.

The scope of Professor Dowson's survey is broad in time, place, and subject. All the major periods in the history of science and technology are covered, including the much-neglected Middle Ages, the Renaissance and other recognised eras of scientific development. For each period the author puts tribology in its social, environmental, and historical context, to show that the science and technology of tribology developed from the need to solve the practical problems of the day.

Lavishly illustrated with photographs, diagrams and line drawings, this edition contains much new material dealing with recent developments in tribology. This immense historical survey has been written for all those concerned with tribology in the belief that future developments can benefit greatly from lessons learnt from the achievements and problems of the past.
