Download or read book Optical Studies of Micron Scale Flows written by Guido Bolognesi and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microfluidics is a very recent branch of science and technology. The development and the success, it has had in the last 15 years, is mainly due to the concept of lab-on-a-chip. Those miniaturized devices, integrating one or more laboratory functions, have aroused great interest among several research areas as physics, chemistry, biology and bioengineering. When a fluid is confined in a micro or nano scale structure, its behaviour is strongly affected by its interactions with the surrounding surfaces. In this context, the theme of fluid/solid slippage has been widely studied both theoretically and experimentally. Innovative technologies to enhance the surface slippage by specifically designing the solid interfaces have reportedly demonstrated to be an effective way to reduce the fluid/solid friction. To this end, superhydrophobic surfaces have increasingly attracted the interest of the scientific and technological community thanks to the large wall-slippage they present for liquid water. Though their behaviour has been extensively investigated through several theoretical and numerical methods, the experimental approaches are still indispensable to test and understand the properties of these surfaces. However, the lack of a general predicting model is also due to the fact that no one of the several existing experimental techniques has shown up as a very reliable one. Indeed, the reported measurements of slippage still depends on the specific adopted method, thwarting attempts to corroborate the proposed theoretical and numerical schemes. Therefore, it is evident that a more sensitive and effective experimental technique is still missing. This thesis began and developed inside the wider project of setting up an innovative technique to investigate the fluid-solid slippage on superhydrophobic surfaces by means of optical tweezers. Even though this project is still going on, this work reports the steps performed along the long way towards this main goal and it consists of a collection of several researches involving different scientific fields as optics, microscopy, surface science, microhydrodynamics, microfluidics and microfabrication. The researches presented in this work can be separated in two main categories: i) holographic micromanipulation and microscopy, ii) superhydrophobicity.

Available in PDF, EPUB and Kindle. Book excerpt: The Sixth International Conference on Miniaturized Chemical and Biochemical Analysis Systems, known as /JTAS2002, will be fully dedicated to the latest scientific and technological developments in the field of miniaturized devices and systems for realizing not only chemical and biochemical analysis but also synthesis. The first /JTAS meeting was held in Enschede in 1994 with approximately 160 participants, bringing together the scientists with background in analytical and biochemistry with those with Micro Electro Mechanical Systems (MEMS) in one workshop. We are grateful to Piet Bergveld and Albert van den Berg of MESA Research Institute of the University of Twente for their great efforts to arrange this exciting first meeting. The policy of the meeting was succeeded by late Prof. Dr. Michael Widmer in the second meeting, /JTAS'96 held in Basel with 275 participants. The first two meetings were held as informal workshops. From the third workshop, /JTAS'98 (420 participants) held in Banff, the workshop had become a worldwide conference. Participants continued to increase in /JTAS2000 (about 500 participants) held in Enschede and /JTAS2001 (about 700 participants) held in Monterey. The number of submitted papers also dramatically increased in this period from 130 in 1998, 230 in 2000 to nearly 400 in 2001. From 2001, /JTAS became an annual symposium. The steering committee meeting held in Monterey, confrrmed the policy of former /JTAS that quality rather than quantity would be the key-point and that the parallel-session format throughout the 3.

Download or read book Advances in Superconductivity VIII written by Hisao Hayakawa and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of superconductivity with trans1tton temperatures above 77 K, concentrated research activities toward the exploration of practical applica tions of these materials have been carried out. Currently, a remarkable improve ment in superconducting properties has been achieved due to the fine optimization of fabrication processes, and this has attracted industrial interest for future applications. In the case of NdBa Cu 0 materials, a new pinning mecha 2 3 7 nism was found which enhances the critical current under applied magnetic fields. In single crystals of these materials, oxygen control results in an increase in the growth rate. The metalorganic chemical vapor deposition (MOCVD) film quality has been improved by using a new liquid raw material. Simultaneously, real demands from the viewpoint of the market start to be a motivation force, es pecially in electronics application where some products are already being sold. At the same time, interesting physical properlies have been obtained from a new superconducting single crystal which has a layered perovskite structure without copper. In addition, various precision measurement techniques have confirmed the d-wave mechanism and the existence of intrinsicJosephson junctions in single crystals. These new phenomena challenge the existing theoretical models but also open the way for new applications. These significant areas of progress in materials science have led high-Tc super conductivity research into the next phase of activity, while fundamental research continues to be very important. I sincerely hope that this volume will give further impetus to this development.

Download or read book Microrheology with Optical Tweezers written by Manlio Tassieri and published by CRC Press. This book was released on 2016-10-14 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to the pioneering works of Ashkin and coworkers, optical tweezers (OTs) have become an invaluable tool for myriad studies throughout the natural sciences. Their success relies on the fact that they can be considered as exceptionally sensitive transducers that are able to resolve pN forces and nm displacements, with high temporal resolution, down to μs. Hence their application to study a wide range of biological phenomena such as measuring the compliance of bacterial tails, the forces exerted by a single motor protein, and the mechanical properties of human red blood cells and of individual biological molecules. The number of articles related to them totals to a whopping 58,000 (source Google Scholar)! Microrheology is a branch of rheology, but it works at micrometer length scales and with microliter sample volumes. Therefore, microrheology techniques have been revealed to be very useful tools for all those rheological/mechanical studies where rare or precious materials are employed, such as in biological and biomedical studies. The aim of this book is to provide a pedagogical introduction to the physics principles governing both the optical tweezers and their application in the field of microrheology of complex materials. This is achieved by following a linear path that starts from a narrative introduction of the "nature of light," followed by a rigorous description of the fundamental equations governing the propagation of light through matter. Moreover, some of the many possible instrumental configurations are presented, especially those that better adapt to perform microrheology measurements. In order to better appreciate the microrheological methods with optical tweezers explored in this book, informative introductions to the basic concepts of linear rheology, statistical mechanics, and the most popular microrheology techniques are also given. Furthermore, an enlightening prologue to the general applications of optical tweezers different from rheological purposes is provided at the end of the book.
