Electrically Active Materials For Medical Devices


Book Description

Stress induced electrical charges, action potential and electret behavior of bone, muscles, skin and nerve cells have been known for some time. Electrically Active Materials for Medical Devices builds on this knowledge and encourages readers to understand and exploit electrical activity in biomaterials from native, derived, or completely synthetic origin, or a combination thereof.

Advanced Nanomaterials for Catalysis and Energy


Book Description

Advanced Nanomaterials for Catalysis and Energy: Synthesis, Characterization and Applications outlines new approaches to the synthesis of nanomaterials (synthesis in flow conditions, laser electrodispersion of single metals or alloys on carbon or oxide supports, mechanochemistry, sol-gel routes, etc.) to provide systems with a narrow particle size distribution, controlled metal-support interaction and nanocomposites with uniform spatial distribution of domains of different phases, even in dense sintered materials. Methods for characterization of real structure and surface properties of nanomaterials are discussed, including synchrotron radiation diffraction and X-ray photoelectron spectroscopy studies, neutronography, transmission/scanning electron microscopy with elemental analysis, and more. The book covers the effect of nanosystems' composition, bulk and surface properties, metal-support interaction, particle size and morphology, deposition density, etc. on their functional properties (transport features, catalytic activity and reaction mechanism). Finally, it includes examples of various developed nanostructured solid electrolytes and mixed ionic-electronic conductors as materials in solid oxide fuel cells and asymmetric supported membranes for oxygen and hydrogen separation. - Outlines synthetic and characterization methods for nanocatalysts - Relates nanocatalysts' properties to their specific applications - Proposes optimization methods aiming at specific applications




Mechcomp3


Book Description

The use of composite materials has grown exponentially in the last decades and has affected many engineering fields due to their enhanced mechanical properties and improved features with respect to conventional materials. For instance, they are employed in civil engineering (seismic isolators, long-span bridges, vaults), mechanical engineering (turbines, machine components), aerospace and naval engineering (fuselages, boat hulls and sails), automotive engineering (car bodies, tires), and biomechanical engineering (prostheses).Nevertheless, the greater use of composites requires a rapid progress in gaining the needed knowledge to design and manufacture composite structures. Thus, researchers and designers devote their own efforts to develop new analysis techniques, design methodologies, manufacturing procedures, micromechanics approaches, theoretical models, and numerical methods. For these purpose, it is extremely easy to find many recent journal papers, books, and technical notes, focused on the mechanics of composites. In particular, several studies are presented to take advantage of their superior features by varying some typical structural parameters (such as geometry, fiber orientations, volume fraction, structural stiffness, weight, lamination scheme). Therefore, this Conference aims to collect contributions from every part of the globe that can increase the knowledge of composite materials and their applications, by engaging researches and professional engineers and designers from different sectors. The same aims and scopes have been reached by the previous editions of Mechanics of Composites International Conferences (MECHCOMP), which occurred in 2014 at Stony Brook University (USA) and in 2016 at University of Porto (Portugal).

Biomaterials and Implant Biocompatibility


Book Description

The scientific advances in life sciences and engineering are constantly challenging, expanding, and redefining concepts related to the biocompatibility and safety of medical devices. New biomaterials, new products, and new testing regimes are being introduced to scientific research practices. In order to provide clinically predictive results and to ensure a high benefit–risk ratio for patients, we need to optimize material and implant characteristics, and to adapt performance and safety evaluation practices for these innovative medical devices. Various characteristics related to materials and implant development such as raw materials composition, implant surface morphology, design, geometry, porosity, and mechanical properties need to be thoroughly characterized before evaluating the biological performance of implants. Furthermore, with the increase of regulatory demands, biological evaluation needs to ensure appropriate models and methods for each implant development stage. This book is a result of the Special Issue of Materials on "Biomaterials and Implant Biocompatibility”, which focused on the recent progress in development, material testing, and the biocompatibility and bioactivity evaluation of various materials including, but not limited to, bioceramics, biopolymers, biometals, composite materials, biomimetic materials, hybrid biomaterials, and drug/device combinations for implants and prostheses with medical applications spanning from soft to hard tissue regeneration. The book covers aspects ranging from investigations into material characterization to in vitro and in vivo testing for the assessment of biological performance of advanced, novel biomaterials and implants.
