Book excerpt: This selection is focused on coatings and films with applications in optoelectronics, such as photovoltaics, photocatalysis, and light-based sensors and phenomena. The studies investigate the optimal composition, crystalline structure, and morphology to deliver the different functionalities sought. Obtaining transparent p-type electrodes is challenging but extremely relevant in optoelectronics. Electric conduction mechanisms and the correlations with structure and doping are discussed. The important issue of the degradation pathways in perovskite-based solar cells and the possibilities offered by different types of coatings to encapsulate the devices as well as the beneficial effect of silica coating as an antireflection and antisoiling layer on well-established solar cells are discussed. New designs of nanoplasmonic films for chemical and biological molecule sensing are reviewed, such as the combination of metallic nanoparticles and nanostructured semiconductors and dispersing metallic or bi-metallic nanoparticles in CuO films. The impacts of structure, defects, and morphology on the photoactivated properties of WO3 films and on the shape memory behavior in Cu–Al–Ni thin films are discussed. Aggregated TiO2 nanoparticles on TiO2 layers are shown to enhance optical transmittance and confer a superhydrophilic characteristic. Finally, aspects of the fundamental characterization of thin films, Drude damping in thin films, and laser-induced deflection technique are discussed.

Book excerpt: During the last decade, novel graphene related materials (GRMs), perovskites, as well as metal oxides and other metal nanostructures have received the interest of the scientific community. Due to their extraordinary physical, optical, thermal, and electrical properties, which are correlated with their 2D ultrathin atomic layer structure, large interlayer distance, ease of functionalization, and bandgap tunability, these nanomaterials have been applied in the development or the improvement of innovative optoelectronic applications, as well as the expansion of theoretical studies and simulations in the fast-growing fields of energy (photovoltaics, energy storage, fuel cells, hydrogen storage, catalysis, etc.), electronics, photonics, spintronics, and sensing devices. The continuous nanostructure-based applications development has provided the ability to significantly improve existing products and to explore the design of materials and devices with novel functionalities. This book demonstrates some of the most recent trends and advances in the interdisciplinary field of optoelectronics. Most articles focus on light emitting diodes (LEDs) and solar cells (SCs), including organic, inorganic, and hybrid configurations, whereas the rest address photodetectors, transistors, and other well-known dynamic optoelectronic devices. In this context, this exceptional collection of articles is directed at a broad scientific audience of chemists, materials scientists, physicists, and engineers, with the goals of highlighting the potential of innovative optoelectronic applications incorporating nanostructures and inspiring their realization.

This book was released on 2014-04-29 with total page 1462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming, pollution, food and water shortage, cyberspace insecurity, over-population, land erosion, and an overburdened health care system are major issues facing the human race and our planet. These challenges have presented a mandate to develop “natural” or “green” technologies using nature and the living system as a guide to rationally design processes, devices, and systems. This approach has given rise to a new paradigm, one in which innovation goes hand-in-hand with less waste, less pollution, and less invasiveness to life on earth. Bioinspiration has also led to the development of technologies that mimic the hierarchical complexity of biological systems, leading to novel highly efficient, more reliable multifunctional materials, devices, and systems that can perform multiple tasks at one time. This multi-volume handbook focuses on the application of biomimetics and bioinspiration in medicine and engineering to produce miniaturized multi-functional materials, devices, and systems to perform complex tasks. Our understanding of complex biological systems at different length scales has increased dramatically as our ability to observe nature has expanded from macro to molecular scale, leading to the rational biologically-driven design to find solution to technological problems in medicine and engineering.The following three-volume set covers the fields of bioinspired materials, electromechanical systems developed from concepts inspired by nature, and tissue models respectively.The first volume focuses on the rational design of nano- and micro-structured hierarchical materials inspired by the relevant characteristics in living systems, such as the self-cleaning ability of lotus leaves and cicadas' wings; the superior walking ability of water striders; the anti-fogging function of mosquitoes' eyes; the water-collecting ability of Namib Desert Beetles and spider silk; the high adhesivity of geckos' feet and rose petals; the high adhesivity of mussels in wet aquatic environments; the anisotropic wetting of butterflies' wings; the anti-reflection capabilities of cicadas' wings; the self-cleaning functionality of fish scales; shape anisotropy of intracellular particles; the dielectric properties of muscles; the light spectral characteristics of plant leaves; the regeneration and self-healing ability of earthworms; the self-repairing ability of lotus leaves; the broadband reflectivity of moths' eyes; the multivalent binding, self-assembly and responsiveness of cellular systems; the biomineral formation in bacteria, plants, invertebrates, and vertebrates; the multi-layer structure of skin; the organization of tissue fibers; DNA structures with metal-mediated artificial base pairs; and the anisotropic microstructure of jellyfish mesogloea. In this volume, sensor and microfluidic technologies combined with surface patterning are explored for the diagnosis and monitoring of diseases. The high throughput combinatorial testing of biomaterials in regenerative medicine is also covered.The second volume presents nature-oriented studies and developments in the field of electromechanical devices and systems. These include actuators and robots based on the movement of muscles, algal antenna and photoreception; the non-imaging light sensing system of sea stars; the optical system of insect ocellus; smart nanochannels and pumps in cell membranes; neuromuscular and sensory devices that mimic the architecture of peripheral nervous system; olfaction-based odor sensing; cilia-mimetic microfluidic systems; the infrared sensory system of pyrophilous insects; ecologically inspired multizone temperature control systems; cochlea and surface acoustic wave resonators; crickets' cercal system and flow sensing abilities; locusts' wings and flapping micro air vehicles; the visual motion sensing of flying insects; hearing aid devices based on the human cochlea; the geometric perception of tortoises and pigeons; the organic matter sensing capability of cats and dogs; and the silent flight of rats. The third volume features engineered models of biological tissues. These include engineered matrices to mimic cancer stem cell niches; in vitro models for bone regeneration; models of muscle tissue that enable the study of cardiac infarction and myopathy; 3D models for the differentiation of embryonic stem cells; bioreactors for in vitro cultivation of mammalian cells; human lung, liver and heart tissue models; topographically-defined cell culture models; ECM mimetic tissue printing; biomimetic constructs for regeneration of soft tissues; and engineered constructs for the regeneration of musculoskeletal and corneal tissue.This three-volume set is a must-have for anyone keen to understand the complexity of biological systems and how that complexity can be mimicked to engineer novel materials, devices and systems to solve pressing technological challenges of the twenty-first century.Key Features:The only handbook that covers all aspects of biomimetics and bioinspiration, including materials, mechanics, signaling and informaticsContains 248 colored figures

Available in PDF, EPUB and Kindle. Book excerpt: The compound eyes of moths are composed by hexagonal arrays of non-close-packed nipples that exhibit low reflectance. The outer surface of the cornea of a moth consists of periodic arrays of conical protuberances, termed corneal nipples, typically of sub-250nm height and spacing. These arrays of subwavelength nipples generate a graded transition of refractive index, leading to minimized reflection over a broad range of wavelengths and angles of incidence. In this chapter, the fabrication, characterization, and modeling of moth-eye antireflection coatings on both transparent substrates (e.g., glass) and semiconductor wafers (such as crystalline silicon and GaAs) are discussed.
