  • high heats by mass removal. Their most common use is as an external heat shield to protect supersonic aerospace vehicles from an excessive buildup of heat caused by air friction at the surface. The ablative material must have a low thermal conductivity in order that the heat may remain concentrated in the thin surface layer. As the surface of the ablator melts or sublimes, it is wiped away by the frictional forces that simultaneously heat newly exposed surfaces. The heat is carried off with the material removed. The less material that is lost, the more efficient is the ablative material....

  • Volcanic eruptions are awesome and destructive; however, this natural phenomenon is beneficial in the long term. One of the earliest known written records of a natural disaster concerned the eruption of Pompeii in A.D. 79, and was recorded by Pliny the Younger in his letters to the historian Tacitus (Jashemski, 1979). Volcanic eruptions, ranging in intensity and numbering between 17 and 27 per year during the past decade (Bullard, 1984), continue to remind us of their potential impacts on the environment.

  • In this paper, Fe3O4-ZnO heterostructure multifunctional nanoparticles (NPs) were successfully prepared in aqueous solution by ultrasound assisted thermolysis. First, iron oxide (Fe3O4) magnetic NPs were prepared by co-precipitation method. The Fe3O4 NPs were modified by 3-aminopropyltriethoxysilane (APTES) to have free amine (-NH2) groups on their surface, then, Zn2+ ions were added and stirred to adsorb onto the surface of Fe3O4-NH2 NPs in alkaline solution at a pH of 11.

  • Cuprous oxide (Cu2O) and Au-Cu2O core-shell nanoparticles were successfully synthesized using the chemical reduction method. The morphology of the synthesized pure Cu2Oparticles can be controlled by varying the amount of reducing agent NH2OH.HCl. Due to their similar crystal structure and relatively small lattice mismatch Cu2O particles are nucleated and locally undergo an epitaxial growth on the surface of the multi-faceted Au seed resulting in a stellated icosahedra Au-Cu2O core-shell particle.

  • The surface properties of 7 different micro–organisms with their 14 different strains were examined. The contact angles of the micro–organism films were measured by a captive–bubble technique. Surface free energies were calculated from the contact angles. Hydrophobicities were also evaluated by adhesion to p–xylene.

  • Constructed wetlands are known widely by their characteristic properties like utilization of natural processes, simple and easy of construction, operation and maintain as well. The constructed subsurface flow wetland is designed as a tank with an impervious boundary to prevent seepage and contain a suitable porous media in which emergent plants grow. The water remains below the surface of the gravel/stone/rock media. Soil in constructed subsurface flow wetland absorbs and stores organic matter several years.

  • Most solar modules used in photovoltaics are currently produced from crystalline and polycrystalline silicon wafers, the representatives of so-called first generation of solar cells. This type of devices are among the most efficient but at the same time the most expensive since they require the highest purity silicon and involve a lot of stages of complicated processes in their manufacture.

  • With the rapid development of nanoscience and nanotechnology over the last decades, great progress has been made not only in the preparation and characterization of nanomaterials, but also in their functional applications. As an important one- dimensional nanomaterial, nanofibers have extremely high specific surface area because of their small diameters, and nanofiber membranes are highly porous with excellent pore interconnectivity.

  • One of the most promising, generally applicable and well-adopted methods to enhance the surface performance of materials is the use of coatings. The reason is that it is extremely difficult and expensive to meet homogeneous materials having on their surface the ensemble of desired properties, such as high hardness, wear resistance, adequate stiffness, increased ductility, chemical inertness, stainlessness, controllable electrical and thermal conductivity behavior, etc.

  • Magnesium alloys have always been attractive to designers due to their low density, only two thirds that of aluminium. This has been a major factor in the widespread use of magnesium alloy castings and wrought products. The present book gives us an overview in some special areas of magnesium alloys concerning technological applications and eco-friendly requirements. Each chapter brings us a new facet relating to the application of magnesium alloy including, as an example, researches with rare earth metals as alloying components in magnesium implants for orthopaedic applications....

  • Scaffolds A scaffold provides a three-dimensional framework to support the tissue or organ-specific cells. The scaffold not only provides mechanical support, but it must also supply critical nutrients and transport metabolites to and from the developing tissue. Important scaffold properties vary depending on the tissue but typically include specific biomechanical properties, porosity, biocompatibility, and appropriate surface characteristics for cell adhesion and differentiation. Scaffolds can be natural materials or synthetic polymers and are typically biodegradable.

  • The invention of scanning tunneling microscope (STM) by Binnig and his colleagues in 1982 opened up the possibility of imaging material surfaces with spatial resolution much superior to the conventional microscopy techniques. The STM is the first instrument capable of directly obtaining three-dimensional images of solid surfaces with atomic resolution. Even though STM is capable of achieving atomic resolution, it can only be used on electrical conductors. This limitation has led to the invention of atomic force microscope (AFM) by Binnig and his co-workers in 1986.

  • In the last two decades, many books have been published on ion implantation and ion-beam processing. Why this one now? After all, the advantages of using an energetic ion beam to modify surfaces with a view to enhancing their tribological, electrochemical, optical and magnetic properties have been known for some time. The aim of this volume is to review the basics of previous work on ion-beam modification of materials and to include enough new material on novel applications to bring newcomers “up to speed” in this exciting area....

  • Volume 3 of the book series Biomathematical and Biomechanical Modeling of the Circulatory and Ventilatory Systems aims at presenting major sets of signaling receptors mainly located at the plasma membrane, 1 in a modeling framework rather than biological perspective. Collecting signaling effectors, their main interactions, and major properties are the first tasks required for any modeling of cell signaling processes. The major objective is to comprehend the complexity of natural phenomena to model these events. In other words, to yield the maximal amount of known information (i.e.
