Liquid Crystalline Polymers: Second Edition A Cambridge University Press 978-0-521-58001-4 - Liquid Crystalline Polymers: Second Edition A. M. Donald, A. H. Windle, and S. Hanna Frontmatter More information LIQUID CRYSTALLINE POLYMERS SECOND EDITION The new edition of this authoritative guide on liquid crystalline polymer (LCP) science has been produced in response to the wealth of new material recently generated in the field. It takes the reader through the theoretical underpinnings to real-world applications of LCP technology in a logical, well-integrated manner. A chapter on liquid crystalline biopolymers has been introduced, whilst the in-depth discussion on applications describes not only maturing fields of high strength structural LCPs, but also a detailed analysis of the developing area of functional materials. The in-depth coverage and detailed glossary establish this as an indispensable text for graduate students and researchers in the polymer field, as well as being of interest to those working in chemistry, physics and materials science. A THENE D ONALD became Professor of Experimental Physics at the University of Cambridge in 1998 after many years as a lecturer and then reader. She was elected as Fellow of the Royal Society in 1999.

Donald, A. H. Windle, and S. Hanna Frontmatter More information Preface to first edition Liquid crystalline polymers lead one into the heartland of interdisciplinary science, where it is an art in itself to thrive without becoming a Jack of all trades and master of none. To explore new frontiers requires depth, but in this subject probably more than any other there is need for a breadth of background, and often a breadth not catered for within the traditional divisions of school and college science education. The subject lies where organic chemistry, physical chemistry, physics and materials science meet. A physicist will discover the need to appreciate something of the chemical diversity of the molecular world, and will begin to become familiar with the chemical language of the trade. A chemist, skilled in the synthesis of new liquid crystalline molecules, will become increasingly familiar with the need of materials people for samples in kilogram rather than milligram quantities, and with the demands of the physicist that the samples be ever purer and better characterised.

  • Mothers in Science
    The aim of this book is to illustrate, graphically, that it is perfectly possible to combine a successful and fulfilling career in research science with motherhood, and that there are no rules about how to do this. On each page you will find a timeline showing on one side, the career path of a research group leader in academic science, and on the other side, important events in her family life. Each contributor has also provided a brief text about their research and about how they have combined their career and family commitments. This project was funded by a Rosalind Franklin Award from the Royal Society 1 Foreword It is well known that women are under-represented in careers in These rules are part of a much wider mythology among scientists of science. In academia, considerable attention has been focused on the both genders at the PhD and post-doctoral stages in their careers. paucity of women at lecturer level, and the even more lamentable The myths bubble up from the combination of two aspects of the state of affairs at more senior levels. The academic career path has academic science environment. First, a quick look at the numbers a long apprenticeship. Typically there is an undergraduate degree, immediately shows that there are far fewer lectureship positions followed by a PhD, then some post-doctoral research contracts and than qualified candidates to fill them. Second, the mentors of early research fellowships, and then finally a more stable lectureship or career researchers are academic scientists who have successfully permanent research leader position, with promotion on up the made the transition to lectureships and beyond.

Land Smith 2021 MELS ii Abstract Sina Queyras, in the essay “Lyric Conceptualism: A Manifesto in Progress,” describes the Lyric Conceptualist as a poet capable of recognizing the effects of disparate movements and employing a variety of lyric, conceptual, and language poetry techniques to continue to innovate in poetry without dismissing the work of other schools of poetic thought. Queyras sees the lyric conceptualist as an artistic curator who collects, modifies, selects, synthesizes, and adapts, to create verse that is both conceptual and accessible, using relevant materials and techniques from the past and present. This dissertation responds to Queyras’s idea with a collection of original poems in the lyric conceptualist mode, supported by a critical exegesis of that work.

  • Research Cards Mildred S Dresselhaus
    Age 7-13 years Research cards Mildred S Dresselhaus About Mildred S Dresselhaus, a Polish-Jewish immigrant, was born in the Bronx in 1930 during the Great Depression. Her family, having fled from Poland, worried about the tensions with the Nazi Party in Germany and the rising anti-Jewish attitudes in the region at the time. As a child she read National Geographic magazines and developed a love of science. She was also a talented musician who won free violin lessons which Wikipedia : Public Domain allowed her to meet some more wealthy and advantaged New York families. Her new friends convinced her of the importance of education and helped her get a place at a girls’ private school in New York City. Mildred became an amazing scientist and went on to study physics at university. As well as raising her four children, born between 1959 and 1964, she became a world-famous materials scientist, fondly known as the ‘Queen of Carbon’. She eventually became one of the first female professors at the prestigious Massachusetts Institute of Technology (MIT). Mildred received the Presidential Medal of Freedom in 2014 from President Obama, in recognition of her huge contribution to the world of science. She went to her lab every day until she was taken into hospital two weeks before her death in 2017. Credit - Georgia Litwack Working scientifically Mildred was very interested in the properties new materials from thin pieces of graphite (a form of materials – particularly in how they behaved of carbon) alternated with other materials only one when electricity or heat passed through them.

  • Let's Not Forget Plants Athene Donald, University of Cambridge, UK My
    Let's Not Forget Plants Athene Donald, University of Cambridge, UK My personal trajectory I hated biology at school and gave it up as soon as I could, after a mere two years. It seemed to me – and this is nearly half a century ago – simply to be a question of labelling parts of plants and animals. I wanted to understand things, not merely be able to chant off a list of etymologically obscure words. Biology has certainly moved on a long way from its heyday of classification, although I fear school biology may have moved less far than the more advanced reaches of research. Perhaps if I were a teenager again I would make different choices, but I have never regretted sticking with physics. As an undergraduate in Cambridge I was taught through the wonderful Natural Sciences Tripos. This, unlike most traditional UK science courses, would have offered me the opportunity to pick up some biology as well as carry on with physics because in the first year all students study three experimental sciences. This is, if you like, its USP and had I been tempted I could have studied Biology of Cells, a course designed (as I learned many years later) explicitly to tempt those with no biology background from school who wanted to understand cell machinery. But, given my lack of love for biology, it never crossed my mind to try it out for size. I stuck with the traditional physicist's trio of Physics, Chemistry and (as it was then called) Crystalline State, a topic which would now be termed Materials, as well as Maths.
