Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2009 in the subject Physics - Nuclear Physics, grade: A, , language: English, abstract: Investigations were carried out on etching behaviour of an engineering polymer Kapton-H (4-4'-oxydiphenylene pyromellitimide). Kapton-H samples were subjected to etching in 4N NaOH at 400 °C and at 500 °C temperatures in pristine as well as irradiated form. Irradiation of pristine Kapton-H specimen was done using 75 MeV/nucleon O+ ion beam of fluence 1.875 x a trillion ions/cm2. The specimen was exposed to etchant for a period of 150 minutes. The effect of etching was observed as half layer thickness removed. Thickness measurements were made at etching cycles of 15 minutes each. It was observed that temperature and the irradiation has their effect on etching behaviour of Kapton-H. Study showed that the temperature results in the increased average bulk etch rate. The average bulk etch rate was also observed to increase with the irradiation of the sample.

Download or read book Mechanical Properties and Deformation Behavior of Materials Having Ultra Fine Microstructures written by Michael Anthony Nastasi and published by Springer Science & Business Media. This book was released on 1993 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the emerging class of new materials characterized by ultra-fine microstrucures. The NATO ASI which produced this book was the first international scientific meeting devoted to a discussion of the mechanical properties and deformation behavior of materials having grain sizes down to a few nanometers. Topics covered include superplasticity, tribology, and the supermodulus effect. Review chapters cover a variety of other themes including synthesis, characterization, thermodynamic stability, and general physical properties. Much of the work is concerned with the issue of how far conventional techniques and concepts can be extended toward atomic scale probing. Another key issue concerns the structure of nanocrystalline materials, in particular, what is the structure and composition of the internal boundaries. These ultra-fine microstructures have proved to challenge even the finest probes that the materials science community has today.

Download or read book High performance Polymers written by Guy Rabilloud and published by . This book was released on 1997 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviews the current status of high performance polymers, in particular polyimides, in the electronics industry. Overviews polymers used for optical lithography, semiconductor encapsulation, packaging, flexible circuitry, and conformal coatings, then examines development of new polyimides for their electrical and optical properties, adhesive strength, thermal expansion, and moisture and solvent diffusion. A chapter is devoted to chemistry of negative and positive photosensitive polyimides. Attention is also paid to process parameters used for deposition techniques, cure cycles, and etching methods. Rabilloud is affiliated with the Centre d'etudes des materiaux organiques pour les technologies avancees. Annotation copyrighted by Book News, Inc., Portland, OR.

Download or read book CRC Handbook of Metal Etchants written by Perrin Walker and published by CRC Press. This book was released on 1990-12-11 with total page 1434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents cleaning and etching solutions, their applications, and results on inorganic materials. It is a comprehensive collection of etching and cleaning solutions in a single source. Chemical formulas are presented in one of three standard formats - general, electrolytic or ionized gas formats - to insure inclusion of all necessary operational data as shown in references that accompany each numbered formula. The book describes other applications of specific solutions, including their use on other metals or metallic compounds. Physical properties, association of natural and man-made minerals, and materials are shown in relationship to crystal structure, special processing techniques and solid state devices and assemblies fabricated. This publication also presents a number of organic materials which are widely used in handling and general processing...waxes, plastics, and lacquers for example. It is useful to individuals involved in study, development, and processing of metals and metallic compounds. It is invaluable for readers from the college level to industrial R & D and full-scale device fabrication, testing and sales. Scientific disciplines, work areas and individuals with great interest include: chemistry, physics, metallurgy, geology, solid state, ceramic and glass, research libraries, individuals dealing with chemical processing of inorganic materials, societies and schools.
