"Synthetic Metals": A Novel Role for Organic Polymers (Nobel Lecture) Copyright((c)) The Nobel Foundation 2001. We thank the Nobel Foundation, Stockholm, for permission to print this lecture.

Since the initial discovery in 1977, that polyacetylene (CH)(x), now commonly known as the prototype conducting polymer, could be p- or n-doped either chemically or electrochemically to the metallic state, the development of the field of conducting polymers has continued to accelerate at an unexpectedly rapid rate and a variety of other conducting polymers and their derivatives have been discovered. Other types of doping are also possible, such as "photo-doping" and "charge-injection doping" in which no counter dopant ion is involved. One exciting challenge is the development of low-cost disposable plastic/paper electronic devices. Conventional inorganic conductors, such as metals, and semiconductors, such as silicon, commonly require multiple etching and lithographic steps in fabricating them for use in electronic devices. The number of processing and etching steps involved limits the minimum price. On the other hand, conducting polymers combine many advantages of plastics, for example, flexibility and processing from solution, with the additional advantage of conductivity in the metallic or semiconducting regimes; however, the lack of simple methods to obtain inexpensive conductive polymer shapes/patterns limit many applications. Herein is described a novel, simple, and cheap method to prepare patterns of conducting polymers by a process which we term, "Line Patterning".

Semiconducting and Metallic Polymers: The Fourth Generation of Polymeric Materials (Nobel Lecture) Copyright(c) The Nobel Foundation 2001. We thank the Nobel Foundation, Stockholm, for permission to print this lecture.

When asked to explain the importance of the discovery of conducting polymers, I offer two basic answers: first they did not (could not?) exist, and second, that they offer a unique combination of properties not available from any other known materials. The first expresses an intellectual challenge; the second expresses a promise for utility in a wide variety of applications.

Jubilee Lecture of the Scottish Paediatric Society. Do we really need community paediatricians? A summary of the lecture given at the Triennial Meeting of the Scottish Paediatric Society.

To summarise, I have supported the development of a specialty of "child development and rehabilitation" as an independent branch of paediatrics separate from neurology; emphasised the importance of expertise in child abuse for all paediatricians and not just those working in "the community"; described the changing role of specialist paediatric doctors in pre-school surveillance and the school health service; and suggested that we may need community paediatricians with a public health orientation. It is important to determine what community paediatricians should do and to ensure that the training they receive is relevant to the tasks required of them.
