Voids in Materials (eBook)

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

Gary Gladysz is an adjunct associate professor of materialsscience and engineering at the University of Alabama atBirmingham, United States and founder at X-Link 3D. Hereceived his PhD from the New Mexico Institute of Miningand Technology, where he participated in the NATOCollaborative Program with the German Aerospace Institute(DLR). Since receiving his PhD, he has led research efforts inuniversity, government, and industrial settings. He has extensiveresearch experience designing and characterizing thermosetcomposite materials for 3D printing, fibrous composites, ceramic composites,polymers, composite foams, and thin films. As a technical staff member at LosAlamos National Laboratory (LANL), he was technical lead for rigid composites andthermoset materials. In 2005 he was awarded the LANL Distinguished PerformanceGroup Award for his work leading materials development on the ReliableReplacement Warhead Feasibility Project. Additionally, while the US Army, he developedcomposite materials and test protocols for ballistic head protection. He hasserved on funding review boards for LANL, National Science Foundation, ACS, andthe Lindbergh Foundation. He has been guest editor on many issues of leadingmaterials science journals, including Journal of Materials Science and MaterialsScience & Engineering. He has organized many international conferences/symposiaon syntactic foams, composite materials, and innovative materials for additivemanufacturing. He started and chairs the ECI international conference series onSyntactic and Composites Foams. He currently lives in Boston, Massachusetts,United States.
