Atomic Force Microscopy: Principles, Developments and Applications presents Atomic Force Microscopy (AFM) as one of the most powerful tools for the analysis of morphologies because it creates three-dimensional images at the angstrom and nano scale. This technique has been exhaustively used in the analyses of the dispersion of nanometric components in nanocomposites and in polymeric blends because of the easiness of the sample preparation and lower equipment maintenance costs compared to the electron microscopy. Contributions to different application areas using the AFM are described, emphasizing the analysis of the morphology of composites/nanocomposites and polymeric blends based on elastomeric materials. Following this, the authors examine the basic concept of DEP and its integration with AFM to generate DEP, as well as review DEP-based AFM methods of imaging local electric polarizability with nanoscale spatial resolution. The direct measurement of DEP strength and polarity using a multi-pass AFM technique is described, contributing to the optimization and calibration of DEP integrated nano-devices for the effective control and manipulation of target biomolecules. The combination of in situ AFM-study of model crystals and ex situ-scanning of natural crystals makes it possible to carry out a partial reconstruction of natural crystallogenetics processes. With the use of these methods and microtomography, the authors estimate the concentration of silica in the mother solution at the time of capture of inclusions was estimated for the first time. Next, a study is presented with the goal of evaluating the morphology of surface asphalt films obtained through spin coating and characterized by AFM. The samples were pure asphalt and modified with two types of asphaltenes called continental type and archipelago type. The asphaltene fractions in the micellar system define the morphological stability of the asphalt resulting from a contribution of all the existing forces between the supramolecules of the system. The closing study presents in situ AFM investigations of crystal dissolution. The statistical data shows considerable differences in tangential dissolution rate on the two spirals consisting of nine and four screw dislocations.

Atomic Force Microscopy (Hardcover): Peter Eaton, Paul West Atomic Force Microscopy (Hardcover)
Peter Eaton, Paul West
R4,110 Discovery Miles 41 100 Ships in 12 - 19 working days

Atomic force microscopy is an amazing technique that allies a versatile methodology (that allows measurement of samples in liquid, vacuum or air) to imaging with unprecedented resolution. But it goes one step further than conventional microscopic techniques; it allows us to make measurements of magnetic, electrical or mechanical properties of the widest possible range of samples, with nanometre resolution. This book will demystify AFM for the reader, making it easy to understand, and to use. It is written by authors who together have more than 30 years experience in the design, construction and use of AFMs and will explain why the microscopes are made the way they are, how they should be used, what data they can produce, and what can be done with the data. Illustrative examples from the physical sciences, materials science, life sciences, nanotechnology and industry illustrate the different capabilities of the technique.

BROADWAY HOUSE 68-74 CARTER LANE, E. G. PRINTED IN GREAT BRITUN BY W. JOLLY AND SONS, LTD., ABERDEEN. FOREWORD. THE inspiration of this brochure was the institution of lectures and practical work on Microscopy as part of the class of Medical Physics in the University of Aberdeen. It was felt that a small textbook covering the work of the systematic lectures would be helpful . to the student and might aid him to realize the capabilities, limitations and proper method of use of the instrument. A chapter on the elementary mathematical treat ment of certain problems discussed in the text has been added. It is hoped that the work will prove of value to all students who require a microscope in their studies as well as to those amateur microscopists who wish to understand the fundamental principles on which Microscopy is based.

INDEX, 85 90 PLATES to face pp. 6, 28, 36 AN INTRODUCTION TO THE THEORY AND USE OF THE MICROSCOPE. THE function of the microscope is to reveal detail of the structure of objects too small to be visible to the unaided eye. This end is attained by the use of a series of lenses which make the object appear magnified to the observer. The magnification to be of value must extend to the finest detail of the object and each successive stage of magnification should reveal structure invisible without its aid.So-called c resolution J of detail in an object does not of necessity result from mere optical magnification. Magnification is necessary to attain it, but other factors are involved. It is the aim of this brochure to explain the principles of microscopy and the manipulations by which resolution is obtained. For these purposes it is essential to consider first certain properties of the simple convex lens, and some of the conditions governing the visibility of objects. THE SIMPLE CONVEX LENS...

Rife's World of Electromedicine - The Story, the Corruption and the Promise (Paperback): Barry Lynes Rife's World of Electromedicine - The Story, the Corruption and the Promise (Paperback)

In 1987, Barry Lynes wrote the classic book on Rife history called The Cancer Cure That Worked. Rife's World of Electromedicine is the sequel, published in 2009. What is the difference between the two books? The Cancer Cure That Worked was primarily a biographical account of Royal Raymond Rife's life and work, including detailed, dated records of the events which occurred, and in-depth accounts from the people involved. Rife's World of Electromedicine, on the other hand, is a bird's eye view, short summary of the same time period and events. Instead of a detailed biography, Rife's World is an expository piece that includes brief, targeted chapters addressing each aspect of Rife's era, utilizing piercing, specific, and direct quotes and excerpts from historical documents including magazine and newspaper articles, court transcripts, Rife's own statements, and the eye-witness accounts of those who were present during Rife's lifelong achievements. Written as a short story, Rife's World is affordably priced so that everyone can read about Royal Raymond Rife. The book is a perfect gift for someone who wants to find out more about Rife but doesn't have time to read a longer book. Additionally, the new book explains what 20] years of additional research and document retrieval by a dedicated grass roots group have discovered and unearthed. Some of the previously missing, key factors in the suppressed and censored cure for cancer were lost or even locked away in physicians' closets for decades in order to prevent censors from destroying overwhelming evidence. Now, this evidence is printed for the first time in Rife's World.

Biomedical scientists are the foundation of modern healthcare, from cancer screening to diagnosing HIV, from blood transfusion for surgery to food poisoning and infection control. Without biomedical scientists the diagnosis of disease, the evaluation of the effectiveness of treatment, and research into the causes and cures of disease would not be possible. The Fundamentals of Biomedical Science series has been written to reflect the challenges of practicing biomedical science today. It draws together essential basic science with insights into laboratory practice to show how an understanding of the biology of disease is coupled to the analytical approaches that lead to diagnosis. Assuming only a minimum of prior knowledge, the series reviews the full range of disciplines to which a Biomedical Scientist may be exposed-from microbiology to cytopathology to transfusion science. Histopathology describes the processes and practices that are central to the role of the histopathology biomedical scientist, from presampling to diagnosis to laboratory management. It demonstrates throughout how an understanding of cell and tissue physiology is vital to the successful identification of clinical conditions.

Secondary Electron Energy Spectroscopy In The Scanning Electron Microscope (Hardcover): Anjam Khursheed Secondary Electron Energy Spectroscopy In The Scanning Electron Microscope (Hardcover)
Anjam Khursheed
R3,081 Discovery Miles 30 810 Ships in 10 - 15 working days

This book deals with the subject of secondary energy spectroscopy in the scanning electron microscope (SEM). The SEM is a widely used research instrument for scientific and engineering research and its low energy scattered electrons, known as secondary electrons, are used mainly for the purpose of nanoscale topographic imaging. This book demonstrates the advantages of carrying out precision electron energy spectroscopy of its secondary electrons, in addition to them being used for imaging. The book will demonstrate how secondary electron energy spectroscopy can transform the SEM into a powerful analytical tool that can map valuable material science information to the nanoscale, superimposing it onto the instrument's normal topographic mode imaging. The book demonstrates how the SEM can then be used to quantify/identify materials, acquire bulk density of states information, capture dopant density distributions in semiconductor specimens, and map surface charge distributions.
