All materials have voids in them, at some scale. Sometimes the voids are ignored, sometimes they are taken into account, and other times they are the focal point of the research. Voids in Materials: From Unavoidable Defects to Designed Cellular Materials takes due notice of all these occurrences, whether designed or unavoidable defects. We define, categorize, and characterize the voids (or empty spaces in materials) and we analyze the effects they have on material properties. This second edition is an updated and expanded central reference for voids in materials and covers all types of voids, intrinsic and intentional, and stochastic and nonstochastic, and the processes and conditions that are needed to create them and is a valuable resource to students in the areas of mechanical engineering, chemical engineering, materials science and engineering, physics, and chemistry, as well as scientists, researchers, and engineers in industry. - the effect of voids in materials; from low volume fraction defects and free volume in polymer networks to high void volume fraction foams and aerogels - how and why voids are introduced into materials across the length scales - biomaterial design used in vivo for soft, hard, and nerve tissue scaffolds - metallic and geopolymeric foams - additive manufacturing technologies used to tailor regularity (R) in the cell structure - stochastic, nonstochastic, and Voronoi foams - the latest techniques for characterizing voids - new chapters, covering the Kirkendall effect to create hollow and porous structures, and nanometer scale voids: nanotubes, zeolites, organic frameworks, and nanoporous noble metals

The first most pertinent question I faced before I could start narrating my story was, what title would sum up the essence of my journey? I thought the title should be apt and inspiring enough for me to stay focused on basic nuances that formed my core belief. A lot of churning spread over few weeks helped and I zeroed in on Karmath Jeevan. To me it means a world and is the most apt description of my life. Simply put, Karmath Jeevan means an action-oriented life; a life dedicated to sincere hard work as a dharma (duty) without undue anxiety for the results. I consider I lived in practice by this principle though not as an articulated thought. The house-hold environment during my childhood days and formative years led me to follow the elders especially my mother, my brother-in-law and two sisters whose daily routines, though apparently ordinary and simple, greatly impacted my mind and my thought process. The visits to temples along with them and listening to discourses of holy men/women influenced me. I learnt; one should focus on the task ahead, act sincerely with honesty of purpose and be satisfied. That was said to be a clear path to leading a meaningful, satisfying and fulfilling life.
Best friends Azim Khan and Karan Nehru never considered politics a career choice, but then fate decreed otherwise. Forced by circumstances to rethink their professions, the two friends find themselves willy-nilly contesting elections. Slowly but surely, Azim makes western Uttar Pradesh his electoral fiefdom and begins his journey to becoming the leader of Muslim India; Karan establishes himself as the overlord of eastern Uttar Pradesh and the adjoining states. Together they make their way to the top, never compromising their friendship, until, finally, as cabinet ministers in a shaky coalition government under the prime ministership of the wily former-Congressman Y.K. Naidu, their widely differing ideologies and temperaments, abetted by the malevolence of their colleagues, and the sheer scale of unfolding events, all combine to uphold the conventional wisdom that there are no friends in politics.
This book is first of its kind ever written for NEET UG, AIIMS & JIPMER. This is a medicine that has cured many patients i.e. its trial has been done in the form of notes and its beneficiaries are across India serving the humanity in the form of doctor. This book is very well designed during PMT preparation days of the respective authors. This book has been updated according to recent exam pattern changes.
A balanced mechanics-materials approach and coverage of the latest developments in biomaterials and electronic materials, the new edition of this popular text is the most thorough and modern book available for upper-level undergraduate courses on the mechanical behavior of materials. To ensure that the student gains a thorough understanding the authors present the fundamental mechanisms that operate at micro- and nano-meter level across a wide-range of materials, in a way that is mathematically simple and requires no extensive knowledge of materials. This integrated approach provides a conceptual presentation that shows how the microstructure of a material controls its mechanical behavior, and this is reinforced through extensive use of micrographs and illustrations. New worked examples and exercises help the student test their understanding. Further resources for this title, including lecture slides of select illustrations and solutions for exercises, are available online at www.cambridge.org/97800521866758.
In the last few years, a significant increase in applications of MMCs has taken place, particularly in the areas of automotive, aerospace, electronics, and recreation. These include continuous fiber reinforced MMCs for cables in power transmission, high temperature superconducting wires, particulate MMCs in civilian aircraft and automotive applications, and high volume fraction, high thermal conductivity substrates for electronic packaging. Nevertheless, as with any novel material systems, there is a lack of fundamental understanding on the part of practicing engineers and designers. This book would seek to address these issues, in a thorough and cohesive manner, as well as to provide students and scientists with a basic understanding of MMCs. This book will emphasize the synergistic relationships among processing, structure, and properties of metal matrix composites.

After an introductory chapter, the processing, microstructure, and properties of various ceramic materials, reinforcements, and their composites are described. A separate chapter is devoted to processing of ceramic reinforcements, with a special emphasis on fibers. Processing of ceramic matrix composites is the next chapter, which includes novel techniques such as sol-gel processing and ceramics from polymeric precursors. The next four chapters cover the subjects of interface region in ceramic composites, mechanical and physical properties, and the role of thermal stresses and the important subject of toughness enhancement. Laminated composites made of ceramics are described in a separate chapter. Finally, a chapter is devoted to various applications of ceramic matrix composites. Throughout the text, the underlying relationships between the components of the triad: processing, microstructure, and properties are brought out. An exhaustive list of references and suggested reading is provided.

The Mystery and Magic of Love inspires the reader to express genuine love and happiness, and so discover the secrets of a good life.
Materials science and engineering (MS&E) is by its very nature an inter disciplinary activity. Researchers from a wide variety of disciplines, metal lurgy, ceramics, physics, chemistry, mechanics, electrical and electronic engineering, etc. can and do participate in the MS&E activities. The need and desirability of such an interdisciplinary effort is understandable inas much as advanced or high-performance materials are critical for any of the modern industries. It is almost a given axiom that progress in any field (energy, building materials, transportation, electronics, aerospace, electric power, consumer products, etc.) depends on the availability of suitable In this regard, let me quote from materials having specific characteristics. another work of mine: It is a truism that technological development depends on advances in the field of materials. One does not have to be an expert to realize that a most advanced turbine or aircraft design is of no use if adequate materials to bear the service loads and conditions are not available. Whatever the field may be, the final limitation on advancement depends on materials [1]. It is pertinent to quote from some other sources about a fundamental change that is occurring in the materials field: A fundamental reversal in the relationship between human beings and materials [has occurred]. Its economic consequences are likely to be profound. Historically humans have adapted such natural materials as stone, wood, clay, vegetable fiber and animal tissue to economic uses.
