Download or read book Analysis of Dynamic Surface Instabilities in Soft Hydrogel Cylinders Subject to Laser driven Shock loading written by Daniel N. Pickard and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft materials subject to both static and dynamic loading are known to exhibit a variety of mechanical instabilities which may lead to intricate surface deformation patterns. In particular, creases and wrinkles have been found to play an important role in the morphogenesis of soft tissues and tumor growth. Soft matter instabilities are also relevant to a number of manufacturing and engineering applications such as the fabrication of microlenses, and the development of soft robots, actuators and ŕexible electronics. Static instabilities in soft matter have been well studied theoretically, and they are known to result from bifurcations of equilibrium due to loss of convexity of the nearly-incompressible elastic strain energy function in the large deformation range. Under dynamic loading, soft solids exhibit many instabilities that are well known in ŕuids, including Rayleigh-Taylor, Faraday and Richtmyer-Meshkov instabilities.

Download or read book Ice Adhesion written by K. L. Mittal and published by John Wiley & Sons. This book was released on 2020-12-15 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book presents ways to mitigate the disastrous effects of snow/ice accumulation and discusses the mechanisms of new coatings deicing technologies. The strategies currently used to combat ice accumulation problems involve chemical, mechanical or electrical approaches. These are expensive and labor intensive, and the use of chemicals raises serious environmental concerns. The availability of truly icephobic surfaces or coatings will be a big boon in preventing the devastating effects of ice accumulation. Currently, there is tremendous interest in harnessing nanotechnology in rendering surfaces icephobic or in devising icephobic surface materials and coatings, and all signals indicate that such interest will continue unabated in the future. As the key issue regarding icephobic materials or coatings is their durability, much effort is being spent in developing surface materials or coatings which can be effective over a long period. With the tremendous activity in this arena, there is strong hope that in the not too distant future, durable surface materials or coatings will come to fruition. This book contains 20 chapters by subject matter experts and is divided into three parts— Part 1: Fundamentals of Ice Formation and Characterization; Part 2: Ice Adhesion and Its Measurement; and Part 3: Methods to Mitigate Ice Adhesion. The topics covered include: factors influencing the formation, adhesion and friction of ice; ice nucleation on solid surfaces; physics of ice nucleation and growth on a surface; condensation frosting; defrosting properties of structured surfaces; relationship between surface free energy and ice adhesion to surfaces; metrology of ice adhesion; test methods for quantifying ice adhesion strength to surfaces; interlaboratory studies of ice adhesion strength; mechanisms of surface icing and deicing technologies; icephobicities of superhydrophobic surfaces; anti-icing using microstructured surfaces; icephobic surfaces: features and challenges; bio-inspired anti-icing surface materials; durability of anti-icing coatings; durability of icephobic coatings; bio-inspired icephobic coatings; protection from ice accretion on aircraft; and numerical modeling and its application to inflight icing.

Download or read book J C Martin on Pulsed Power written by T.H. Martin and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: As indicated in the Foreword to this series on Advances in Pulsed Power Technologies, the pioneering roots of modern pulsed power as related by J.C. "Charlie" Martin and his co-workers of the Atomic Weapons Research Establishment, Aldermaston, Reading UK is an important if not essential record of the experiential history of the major developer of pulsed power advances during the post-World War II period. It finds great utility as an instructive accounting of the trials, tribulations and, finally, an almost chronological walk through their thoughts as they diligently and happily travel the yellow brick road to success. It is recounted in the inimitable style of "Charlie" Martin as only he can relate, with some insightful perspectives by Mike Good man, a constant companion, and collaborator who shares his unique view of "Charlie" and the Aldermaston Group. This collection of selected articles is unique, for in large part, the documentation of their struggle and final triumph have not been formerly published in any archival manner. One reason, we suspect, was the defense-related application and significance of their work, compounded by the constant need for progress which did not allow for the time consuming preparation of formal submission to the literature. This also explains the "urgent" and sometimes terse manner of their writings. Yet the material remains remarkably current because we are dealing, in large measure, with pulsed systems less sensitive to those factors involved in slower pulsed scenarios.

Download or read book Angiogenesis Assays written by Carolyn A. Staton and published by John Wiley & Sons. This book was released on 2007-01-11 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angiogenesis, the development of new blood vessels from the existing vasculature, is essential for physiological growth and over 18,000 research articles have been published describing the role of angiogenesis in over 70 different diseases, including cancer, diabetic retinopathy, rheumatoid arthritis and psoriasis. One of the most important technical challenges in such studies has been finding suitable methods for assessing the effects of regulators of eh angiogenic response. While increasing numbers of angiogenesis assays are being described both in vitro and in vivo, it is often still necessary to use a combination of assays to identify the cellular and molecular events in angiogenesis and the full range of effects of a given test protein. Although the endothelial cell - its migration, proliferation, differentiation and structural rearrangement - is central to the angiogenic process, it is not the only cell type involved. the supporting cells, the extracellular matrix and the circulating blood with its cellular and humoral components also contribute. In this book, experts in the use of a diverse range of assays outline key components of these and give a critical appraisal of their strengths and weaknesses. Examples include assays for the proliferation, migration and differentiation of endothelial cells in vitro, vessel outgrowth from organ cultures, assessment of endothelial and mural cell interactions, and such in vivo assays as the chick chorioallantoic membrane, zebrafish, corneal, chamber and tumour angiogenesis models. These are followed by a critical analysis of the biological end-points currently being used in clinical trials to assess the clinical efficacy of anti-angiogenic drugs, which leads into a discussion of the direction future studies should take. This valuable book is of interest to research scientists currently working on angiogenesis in both the academic community and in the biotechnology and pharmaceutical industries. Relevant disciplines include cell and molecular biology, oncology, cardiovascular research, biotechnology, pharmacology, pathology and physiology.
