Book Description
In my research, I have performed many characterization and fabrication experiments that are based on tools of analytical chemistry, materials chemistry, and surface science. My research projects are as follows. (1) Fabrication of transparent polymer templates for nanostructured amorphous silicon photovoltaics was done using low-cost nanoimprint lithography of polydimethylsiloxane. This approach provides a test bed for absorption studies in nanostructured film geometries and should result in improved light capturing designs in thin-film solar cells. Nanopatterned polymer films were characterized by scanning electron microscopy and optical measurements. (2) A straightforward method for fabricating freely suspended, thin, carbon nanotube (CNT) membranes infiltrated with polymers was developed. This process is a new approach for making thin, reinforced, smooth films or membranes with high concentrations of CNTs, which may lead to higher performance materials. Characterization of the film and membrane was performed via scanning electron microscopy and atomic force microscopy. (3) Laser activation-modification of semiconductor surfaces (LAMSS) was carried out on silicon with a series of 1-alkenes. A key finding from this study is that the degree of surface functionalization in a LAMSS spot appears to decrease radially from the center of the spot. These laser spots were studied by time of flight secondary ion mass spectrometry (ToF-SIMS), and the resulting spectra were analyzed using a series of chemometrics methods. (4) A large ToF-SIMS data set from multiple coal samples spanning a wide range of coal properties was subjected to a chemometrics analysis. This analysis separates the spectra into clusters that correspond to measurements from classical combustion analyses. Thus ToF-SIMS appears to be a promising technique for analysis of this important fuel. (5) Several experiments on carbon nanotube processing were performed in my research, including carbon nanotube sheet formation, carbon nanotube purification, carbon nanotube dispersion, and carbon nanotube functionalization. X-ray photoelectron spectroscopy was a key characterization tool for many of these experiments.

Book Description
The Special Issue “Synthesis and Modification of Nanostructured Thin Films” highlights the recent progress in thin film synthesis/modification and characterization. New methods are reviewed for the synthesis and/or modification of thin films based on laser, magnetron, chemical, and other techniques. The obtained thin nanostructures are characterized by complex and complementary techniques. We think that most of proposed methods can be directly applied in production, but some others still need further elaboration for long-term prospective applications in lasers, optics, materials, electronics, informatics, telecommunications, biology, medicine, and probably many other domains. The Guest Editor and the MDPI staff are therefore pleased to offer this Special Issue to interested readers, including graduate and PhD students as well as postdoctoral researchers, but also to the entire community interested in the field of nanomaterials. We share the conviction that this can serve as a useful tool for updating the literature, but also to aid in the conception of new production and/or research programs. There is plenty of room for further dedicated R&D advances based on new instruments and materials under development.

Book Description
Materials development has reached a point where it is difficult for a single material to satisfy the needs of sophisticated applications in the modern world. Nanocomposite films and coatings achieve much more than the simple addition of the constitutents OCo the law of summation fails to work in the nano-world. This book encompasses three major parts of the development of nanocomposite films and coatings: the first focuses on processing and properties, the second concentrates on mechanical performance, and the third deals with functional performance, including wide application areas ranging from mechanical cutting to solar energy and from electronics to medicine. Sample Chapter(s). Chapter 1: Magnetron Sputtered Hard and Yet Tough Nanocomposite Coatings With Case Studies: Nanocrystalline Tin Embedded in Amorphous SiNx (187 KB). Contents: Magnetron Sputtered Hard and Yet Tough Nanocomposite Coatings with Case Studies: Nanocrystalline TiN Embedded in Amorphous SiN x (S Zhang et al.); Magnetron Sputtered Hard and Yet Tough Nanocomposite Coatings with Case Studies: Nanocrystalline TiC Embedded in Amorphous Carbon (S Zhang et al.); Properties of Chemical Vapor Deposited Nanocrystalline Diamond and Nanodiamond/Amorphous Carbon Composite Films (S C Tjong); Synthesis, Characterization and Applications of Nanocrystalline Diamond Films (Z-Q Xu & A Kumar); Properties of Hard Nanocomposite Thin Films (J Musil); Nanostructured, Multifunctional Tribological Coatings (J J Moore et al.); Nanocomposite Thin Films for Solar Energy Conversion (Y-B Yin); Application of Silicon Nanocrystal in Non-Volatile Memory Devices (T P Chen); Nanocrystalline Silicon Films for Thin Film Transistor and Optoelectronic Applications (Y-J Choi et al.); Amorphous and Nanocomposite Diamond-Like Carbon Coatings for Biomedical Applications (T I T Okpalugo et al.); Nanocoatings for Orthopaedic and Dental Application (W-Q Yan).

Book Description
Nanotechnology is a 'catch-all' description of activities at the level of atoms and molecules that have applications in the real world. A nanometre is a billionth of a metre, that is, about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. Nanotechnology is now used in precision engineering, new materials development as well as in electronics; electromechanical systems as well as mainstream biomedical applications in areas such as gene therapy, drug delivery and novel drug discovery techniques. This book presents carefully selected abstracts of the last 5 years in this frontier field. Special access is provide by author, title and subject indexes.

Book Description
In recent years, carbon nitride, a new type of two-dimensional (2D) material, has attracted great interest, in terms of fundamental scientific investigation and potential practical applications, for a range of energy and environmental technologies. This can be largely attributed to its optoelectronic and physicochemical properties, including moderate band gap, adjustable energy band configuration, tailor-made surface functionalities, low cost, metal-free nature, remarkable thermochemical stability, and environmentally benign manufacturing protocol. Nanostructured Carbon Nitrides for Sustainable Energy and Environmental Applications offers a comprehensive, authoritative, and critical account of the recent progress in the development and application of multifunctional carbon nitride materials and their hybrid heterostructures. There are two major objectives of this book: first, to provide a systematic overview of the key design principles toward the fabrication of high-performance carbon nitride–based nanostructures; and second, to provide insights into a range of clean energy technologies and environmental remediation methods that build on these nanoengineered carbon nitrides. This book serves as an important reference source for materials scientists and engineers who are interested in developing their understanding of how carbon-based nanomaterials are being used for sustainable energy and environmental applications. - Helps users gain deeper insights into various aspects of carbon nitride materials from multidisciplinary perspectives - Covers how to apply nanostructured carbon nitrides to tackle global energy and environmental challenges in a sustainable manner - Explains the design and fabrication of carbon nitride-based materials with optimized structures, controlled morphologies, and tailored properties for practical implementation
