J. Gardner - Böcker

This book provides provocative information on poetry written in response to the most revolutionary set of events seen in Britain since the 1640s: 'Peterloo', a peaceful protest that became a massacre; 'Cato Street', a government scripted rebellion; and the 'Queen Caroline Controversy', when the estranged wife of George IV tried to claim her crown.

"Sensors and Sensory Systems for an Electronic Nose" reviews the current state of progress in the development of an electronic instrument capable of olfaction. The instrument - the so-called electronic nose - has enormous potential for application in such areas as product flavour control and environmental monitoring. The book discusses the essential elements of an electronic nose, such as chemical sensors, signal processing and pattern recognition techniques.

This book examines both the potential application of electronic nose technology, and the current state of development of chemical sensors for the detection of vapours from explosives, such as those used in landmines. The two fields have developed, somewhat in parallel, over the past decade and so one of the purposes of this workshop, on which the book is based, was to bring together scientists from the two fields in order to challenge the two communities and, mutually, stimulate both fields.It begins with a review of the basic principles of an electronic nose and explores possible ways in which the detection limit of conventional electronic nose technology can be reduced to the level required for the trace levels observed for many explosive materials. Next are reviews of the use of several different types of solid-state chemical sensors: polymer-based sensors, i.e. chemiluminescent, fluorescent and optical, to detect explosive materials; metal oxide semiconducting resistive sensors; and then electrochemical sensors. Next, different pattern recognition techniques are presented to enhance the performance of chemical sensors. Then biological systems are considered as a possible blue-print for chemical sensing. The biology can be employed either to understand the way insects locate odorant sources, or to understand the signal processing neural pathways. Next is a discussion of some of the new types of electronic noses; namely, a fast GC column with a SAW detector and a micromechanical sensor. Finally, the important issues of sampling technologies and the design of the microfluidic systems are considered. In particular, the use of pre-concentrators and solid phase micro extractors to boost the vapour concentration before it is introduced to the chemical sensor or electronic nose.
