Book excerpt: Biological surfaces have evolved to optimize their structures and physical and chemical properties at the micro/nanoscale for adaptation to different environments, exhibiting a wide variety of beneficial functions, ranging from optical properties to wettability, such as anti-reflection coatings in moth eyes and self-cleaning surfaces of lotus leaves. Combining optical and wetting functions in multifunctional materials is critical for practical engineering applications such as energy harvesting, color generation, and operation of optical instrumentation in humid conditions. However, analyses of the functional design constraints of specified optical and wetting functions followed by integrative optimization have been rare, and limited to simple pairwise combinations from two distinct research disciplines. Furthermore, fabricating the desired multifunctional nanostructured materials remains a difficult engineering challenge due to the limitations of existing nanofabrication methods. The work in this thesis focuses on the joint control of light transport and surface wettability. It starts with analysis and design, followed by implementation of new multifunctional nanostructured materials using novel nanolithographic fabrication techniques. We first consider multifunctional silica surfaces consisting of conical nanostructures (nanocones) for enhanced omnidirectional broadband transmissivity in conjunction with structural superhydrophilicity or robust superhydrophobicity. This is achieved through a systematic approach to concurrent design of nanostructures in both domains and an innovative fabrication procedure that achieves the desired aspect-ratios and periodicities in the nanocones with few defects, high feature repeatability, and large pattern area. Enhanced optical transmissivity exceeding 98% has been achieved over a broad bandwidth and range of incident angles independent of the polarization state. These nanotextured surfaces also demonstrate robust anti-fogging or self-cleaning properties, offering potential benefits for applications such as photovoltaic solar cells. As an extended function of this silica nanocone surface, we propose the systematic design and development of nanostructured transparent anti-fingerprint surface coatings that degrade fingerprint oils using photocatalytic effects. The TiO2-based porous nanoparticle surfaces exhibit short timescales for decomposition of fingerprint oils under ultraviolet light, plus they have transparency comparable to typical glass with low optical haze (

Available in PDF, EPUB and Kindle. Book excerpt: On the liquid 's surface, the molecules have fewer neighbors in comparison with the bulk volume. As a result, the energy interaction shows itself in the surface tension. Traditionally, the surface tension can be assumed as a force in the unit of the length which can be counted by the unit of Newton on squared meter, or energy on the units of the surface. The surface tension, implies the interface between liquid and vapor, which is an example of the surface tensions. The equilibrium between these surface tensions, decides that a droplet on a solid surface, would have a droplet form or will change to layer form. This book collects new developments in wetting and wettability science.

Available in PDF, EPUB and Kindle. Book excerpt: Intelligent materials are emerging composite functional materials that have boomed since the 1990s. The intelligent material system, involving a multitude of structures and functions, combines studies that explore nature, mimic nature and surpass nature. It also provides novel ideas, new theories, and cutting-edge methodologies for the innovation of science and technology. Thus, mimicking the micro/nanostructures and functions found in nature will build a bridge between biology and technology, which may provide inspirations for solving today's technological problems. This book gives a complementary introduction about natural and artificial micro/nanoscale interfacial materials, devoting largely to the intelligent materials with special wettabilities. Inspired by nature, the authors proposed a concept of "binary cooperative complementary micro/nanoscale interfacial materials". Based on this design concept, the contact and coupling of heterogeneous materials will result in novel properties on the surface or interface of materials, which may create new functional materials and devices. This book combines popular science and professional knowledge, which will be suitable for not only researchers but also science lovers.

This book was released on 2015 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanostructured surfaces have given rise to many unique optical properties, such as broadband anti-reflectivity, structural coloring effects, and enhanced light extraction from high refractive index materials due to their potential to modulate optical behavior on their surfaces. This thesis focuses on design, analysis, and fabrication of functional nanostructured surfaces for efficient light transport, seeking optimized optical performance, high mechanical robustness, and manufacturability, with the aim of increasing the practicality of the photonic nanostructures. First, for the case when light propagates from a low-index material to a high-index material, I designed and fabricated an array of inverted nanocones that realizes anti-reflectivity with robust mechanical strength. The surface exhibits broadband, omnidirectional anti-reflectivity due to the axially varying effective refractive index of the inverted nanocone arrays. The surface also maintains its optical performance after being externally loaded, thanks to low stress concentration and small deflection of the inverted nanocone structure. In addition, for multi-optical interfacial surfaces, double-gradient- index nanostructures are proposed and demonstrated in order to achieve ultimate anti-reflectivity. The top surface, textured with inverted nanocones, maintains high mechanical robustness. Second, for the case where light has to be extracted from high-index materials, a conical photonic crystal is proposed and demonstrated. The tapered conical geometry suppresses Fresnel reflections at the optical interfaces due to adiabatic impedance matching. Periodicity of the arrays of cones diffracts light into higher-order modes with different propagating angles, enabling certain photons to overcome total internal reflection (TIR). After optimizing the structural geometries to balance Fresnel reflection and TIR, light yield efficiency is characterized experimentally on scintillator surfaces. In order to enhance the adaptability to industrial manufacturing, the fabrication methods are based on replicating the photonic nanostructures into a UV-curable polymer, with the help of laser interference lithography as a method of fabricating a master mold. Advanced techniques such as vacuum assisted-filling and a selective delaminating method are also developed to produce nanostructures more effectively. The novel nanostructured surfaces designed in the thesis, and the ability to imprint these topographies through several generations, are promising for large-scale commercial applications where efficient light transport is important.

Book excerpt: Timely information on scientific and engineering developments occurring in laboratories around the world provides critical input to maintaining the economic and technological strength of the United States. Moreover, sharing this information quickly with other countries can greatly enhance the productivity of scientists and engineers. These are some of the reasons why the National Science Foundation (NSF) has been involved in funding science and technology assessments comparing the United States and foreign countries since the early 1980s. A substantial number of these studies have been conducted by the World Technology Evaluation Center (WTEC) managed by Loyola College through a cooperative agreement with NSF. The National Science and Technology Council (NSTC), Committee on Technology's Interagency Working Group on NanoScience, Engineering and Technology (CT/IWGN) worked with WTEC to develop the scope of this Nanostucture Science and Technology report in an effort to develop a baseline of understanding for how to strategically make Federal nanoscale R&D investments in the coming years. The purpose of the NSTC/WTEC activity is to assess R&D efforts in other countries in specific areas of technology, to compare these efforts and their results to U. S. research in the same areas, and to identify opportunities for international collaboration in precompetitive research. Many U. S. organizations support substantial data gathering and analysis efforts focusing on nations such as Japan. But often the results of these studies are not widely available. At the same time, government and privately sponsored studies that are in the public domain tend to be "input" studies.
