These patterns feature simple hexagonally periodic surface composed of a Silicon stem and a thin Silicon Dioxide Cap. The first task of this work was to measure wetting properties including advancing, receding and sessile contact angles as well as breakthrough pressure. These results were used to create a model based on the fraction of the droplet periphery that wets the surface, as opposed to using the entire fraction of wetted surface area beneath a droplet. This model predicts contact angles more accurately than existing equations. These equations, specifically Cassie's and Wenzel's law, are in common use even though some of their basic underpinnings are debated to be fundamentally flawed. The results of this work will also act to clear up this ongoing debate. The second task was to test the hypothesis that these periodic undercut patterns could be used as a more efficient nucleate boiling surface due to vapor trapping and liquid entrainment into the network of structures. This type of liquid entrainment effect was expected to be similar to that previously proposed to explain the enhanced boiling on pore and tunnel type surfaces. However, these surfaces can be produced on a smaller scale, which adds to the liquid entrainment by enhancing capillary wicking. The result was a significant increase in critical heat flux due to small vortices pulling liquid into the surface. The parametric variations in the surfaces provided insight into the size scales that will maximize the intended effects. The influence of feature height, depth of undercut, cap thickness, size and spacing were all determined.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at identifying novel advanced materials of extreme wetting properties (MEWP) for practical, industrial applications. The state-of-the art superhdyrophobic, superhdyrophilic, superoleophobic, superoleophilic, and superomniphobic materials, that are MEWP, with respect to their technological and emerging industrial applications are discussed in this book. MEWP offer new perspectives providing numerous potential applications. Hence, these advanced MEWP have the potential to lead to a new generation of products and devices with unique properties and functionalities. Despite the large scientific progress on MEWP there are still some obstacles which have to be solved to make these materials available for real life applications. Recent advances on the production strategies, including methods and materials, of MEWP has shown that the durability and sustainability obstacles can be addressed thus offering the possibility for industrial exploitation. MEWP with wettabilities ranging from superhydrophobicity to superhydrophilicity provide promising avenues for several and important applications, which sometimes are crucial for the humankind. This book also discusses a large variety of other potential applications of MEWP, thus providing new ideas to scientists and engineers for further exploitation of these novel materials. Moreover, the whole spectrum of the recent technological developments, current research progress, future outlook, and the modern trends in the applications of MEWP are discussed in a consistent approach.

This book was released on 2013-04-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's shortages of resources make the search for wear and corrosion resistant materials one of the most important tasks of the next century. Since the surface of a material is the location where any interaction occurs, it is that there the hardest requirements on the material are imposed: to be wear resistant for tools and bearings; to be corrosion resistant for turbine blades and tubes in the petrochemical industry; to be antireflecting for solar cells; to be decorative for architectural panels and to combine several of these properties in other applications. Surface engineering is the general term that incorporates all the techniques by which a surface modification can be accomplished. These techniques include both coating and modification of the surface by ion implantation and laser beam melting. In recent years a continuously growing number of these techniques were developed to the extent that it became more and more difficult to maintain an overlook and to understand which of these highly differentiated techniques might be applied to resolve a given surface engineering problem. A similar development is also occuring for surface characterization techniques. This volume contains contributions from renowned scientists and engineers to the Eurocourse the aim of which was to inform about the various techniques and to give a comprehensive survey of the latest development on this subject.
