Voids in Materials


Book Description

Voids in Materials treats voids of different shapes and forms in various materials, and examines their effects on material properties. The book covers the origins of voids in materials, how they are sometimes introduced in the form of hollow spheres, and the resultant properties of materials containing voids. There are many books that focus on foams (which intentionally incorporate voids into materials) and that cover voids incidental to or unwanted in the fabrication of non-porous materials. In fact, all materials have voids. This book starts from the premise that voids are pervasive in all material on some level. It goes beyond foams to provide a comprehensive overview of voids, a central reference for scientists and engineers to use for the effect of voids in materials. - Includes 3D renderings of void geometries - Explains how and why voids are introduced into materials across the length scales; from nanometer-scale voids up to macro-scale voids - Provides a continuous picture of how material properties change as the volume fraction of voids increases, and the implications for product design

A Void


Book Description

"...a daunting triumph of will pushing its way through imposing roadblocks to a magical country, an absurdist nirvana of humor, pathos, and loss."--Time magazine A Void is a metaphysical whodunit, a story chock-full of plots and subplots, of trails in pursuit of trails, all of which afford Perec occasion to display his virtuosity as a verbal magician. It is also an outrageous verbal stunt: a 300-page novel that never once employs the letter E. The year is 1968, and as France is torn apart by social and political anarchy, the noted eccentric and insomniac Anton Vowl goes missing. Ransacking his Paris flat, his best friends scour his diary for clues to his whereabouts. At first glance these pages reveal nothing but Vowl's penchant for word games, especially for "lipograms," compositions in which the use of a particular letter is suppressed. But as the friends work out Vowl's verbal puzzles, and as they investigate various leads discovered among the entries, they too disappear, one by one by one, and under the most mysterious circumstances . . .







Vital Voids


Book Description

The Resurrection Plate, a Late Classic Maya dish, is decorated with an arresting scene. The Maize God, assisted by two other deities, emerges reborn from a turtle shell. At the center of the plate, in the middle of the god’s body and aligned with the point of emergence, there is a curious sight: a small, neatly drilled hole. Art historian Andrew Finegold explores the meanings attributed to this and other holes in Mesoamerican material culture, arguing that such spaces were broadly understood as conduits of vital forces and material abundance, prerequisites for the emergence of life. Beginning with, and repeatedly returning to, the Resurrection Plate, this study explores the generative potential attributed to a wide variety of cavities and holes in Mesoamerica, ranging from the perforated dishes placed in Classic Maya burials, to caves and architectural voids, to the piercing of human flesh. Holes are also discussed in relation to fire, based on the common means through which both were produced: drilling. Ultimately, by attending to what is not there, Vital Voids offers a fascinating approach to Mesoamerican cosmology and material culture.




Voids in Materials


Book Description

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




Void


Book Description

The New York Times bestselling author of The Physics of Wall Street “deftly explains all you wanted to know about nothingness—a.k.a. the quantum vacuum” (Priyamvada Natarajan, author of Mapping the Heavens). James Owen Weatherall’s bestselling book, The Physics of Wall Street, was named one of Physics Today’s five most intriguing books of 2013. In this work, he takes on a fundamental concept of modern physics: nothing. The physics of stuff—protons, neutrons, electrons, and even quarks and gluons—is at least somewhat familiar to most of us. But what about the physics of nothing? Isaac Newton thought of empty space as nothingness extended in all directions, a kind of theater in which physics could unfold. But both quantum theory and relativity tell us that Newton’s picture can’t be right. Nothing, it turns out, is an awful lot like something, with a structure and properties every bit as complex and mysterious as matter. In his signature lively prose, Weatherall explores the very nature of empty space—and solidifies his reputation as a science writer to watch. Included on the 2017 Best Book List by the American Association for the Advancement of Science (AAAS) “An engaging and interesting account.”—The Economist “Readers get a dose of biography while following such figures as Einstein, Dirac, and Newton to see how top theories about the void have been discovered, developed, and debunked. Weatherall’s clear language and skillful organization adroitly combines history and physics to show readers just how much ‘nothing really matters.’”—Publishers Weekly




Clusters as an instrument to bridge institutional voids in transition economies


Book Description

Transition economies, such as the countries in Southeast Europe, face an expeditious institutional transition from a centrally planned to a market economy. The state withdraws from its monitoring function, which results in institutional voids that affect the economy in general and small and medium sized enterprises (SMEs) in specific. With a qualitative case study approach Tine Schrammel develops a scheme to detect institutional voids as one source of competitive disadvantages of SMEs in transition economies. In a second step she demonstrates that specific cluster services bridge institutional voids and improve the competitive position of SMEs in environments of institutional voids. The findings add to the understanding of institutional voids and to the role of clusters in transition economies.




A Glossary of Urban Voids


Book Description

This book is a critiqued collection of over 200 terms regularly used to name the urban void, from the terrain vague to the buffer zone. As the landscape architect James Corner has pointed out, a void cannot be labeled because "to name it is to claim it in some way." By listing existing terms, A Glossary of Urban Voids is an attempt to name the unnamable, to define that which should have no precise definition. It records terms, names, and labels used to designate leftover spaces resulting from processes of urban abandonment that originate from some kind of obsolescence or loss. Besides obvious consequences, these processes of abandonment open up the space, liberating it from existing ideological frameworks (such as financial, capital, or cultural frameworks), allowing for divergent spatialities to emerge, and ultimately offering opportunities for the imagination and conceptualization of an alternative type of public space. Using the glossary as a theoretical tool, this book presents the most relevant questions on the issue of the urban void and its potential role as public space.




V.O.I.D.


Book Description

The spirit of the Living God spoke to me one day and said,V.O.I.D. I remember writing it down on a post-it and putting it on my desk. Not understanding why He would give me this word the way I was instructed to write it. Beverly had so many missing pieces to her life. Like those small puzzle pieces that are the hardest to find where they fit because the puzzle is scrambled. Until it is so challenging to get the pieces to fit correctly. Beverly became sad when she was not able to recall birthdays or holidays celebrations like most kids. Who hand had she held on the first day of school? Who cared for her when her stomach hurt? Or when she felt scared of the dark? It was almost as if someone erased those memories from her mind, and she struggled to make sense of those days, even in her adulthood. The VOIDS in Beverly’s life were about to turn into Victories. The VOIDS that she kept trying to fill would never be filled by her own doing. No relationship except one with the creator could fill her VOIDS. No man, child, money, job, drugs, alcohol, or sexual encounters would ever fill what God left empty for His purpose.
