Abstract

Nowadays, transition metal-oxides can be considered the most investigated materials especially in their nanostructured forms thanks to their intrinsic smart properties and to the positive effects induced by scaling their dimension down to the nanoscale. Among them, ZnO and TiO2 have attracted particular interest mainly because of their multi-functionality applicable in an enormous range of research fields. The present Special Issue – composed by twenty-seven papers, both reviews and research articles - covers the most recent advances in ZnO and TiO2 nanostructures, concerning not only their synthesis and characterization, but also reports of the manner(s) in which their functional and smart properties can be applied in working devices. Applications of such nanostructures can range widely, from biomedical and drug delivery devices to piezoelectric and chemical sensors, and energy harvesting, conversion, and storage devices.

Abstract

This book covers major important aspects of nanostructured solar cells of varying types. From fundamental physicochemical investigations to technological advances, and from single junction solar cells (silicon solar cell, dye sensitized solar cell, quantum dots sensitized solar cell, and small molecule organic solar cell) to tandem multi-junction solar cells, all aspects are included and discussed to advance the use of nanotechnology to improve the performance of solar cells with reduced fabrication costs. Most recent studies of nanostructured solar cells have been integrated in this book, allowing readers to quickly follow recent developments in this area.

Abstract

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms.[In recent years, advanced nanocomposites have attracted a great deal of attention from materials engineers and industrialists due to numerous advantages, including the use of a small amount of nanofillers to significantly enhance the material properties of resulting nanocomposites, widespread applications in a range of fields, such as automobiles, aerospace and aerocrafts, building structures, biomedical devices, etc., as well as easy processibility based on current manufacturing technologies, such as melt compounding, solution casting, in situ polymerisation and electrospinning. Advanced nanocomposites reinforced with carbon nanotubes (CNTs), graphene oxides (GOs), nanoclays, nanocellulose, and nanofibres demonstrate excellent multifunctional properties, consisting of better mechanical, thermal, electrical, and barrier properties. The key issue is still the encountered challenge of homogeneous filler dispersion in morphological structures for tailored advanced nanocomposites. Hence, processing-structure-property nanocomposite relationship is crucial for their future development as innovative hybrid material systems.This Special Issue will address above-mentioned points in relation to manufacturing, characterisation, and properties of advanced nanocomposites to offer an insight into this new composite family with the incorporation of nanofillers, nanoparticles, and nanomaterials in order to eventually achieve the nanotechnological "bottom-up" scheme.

Abstract

This computational study investigates diverse bonding situations in nanostructures (carbon nanotubes, fullerenes, metal compounds) spanning a broad range of energies. Weak, dispersive interactions and covalent metal-ligand and metal-metal bonding are examined. The results of efficient density functional calculations are compared to those of correlated wavefunction calculations on model systems. This rigorous validation is crucial in evaluating the balance between computational cost and accuracy.

Abstract

The dispersion of nanomaterials in liquid crystals, both of the thermotropic and the lyotropic kind, has attracted much interest over recent years. This is in part related to the success of liquid crystals in several applications, in particular flat screen displays, besides others. The dispersion of nanoparticles allows the fine-tuning of liquid crystalline properties and the addition of functionalities associated with the properties of the nanoparticles. These include the addition of ferroelectricity, magnetic properties, optic and plasmonic properties, for example through quantum dots and gold nanoparticles, but also directed conductivity, by exploiting the respective conductivity anisotropy of nanotubes. In addition, such behaviors can be achieved through transfer and templating of the self-organization of the liquid crystalline order onto dispersed anisotropic nanoparticles, allowing the formation of ordered nanostructures. Furthermore, the formation of partially ordered fluids can be induced by dispersing shape anisotropic nanoparticles in an isotropic solvent. Such lyotropic systems have recently experienced a revived interest. This genuinely multidisciplinary field of research has led to a wealth of novel systems in soft condensed matter and promises new applications in the areas of displays, optical elements, meta-materials, sensors, drug delivery, and many more. Various examples are presented in this publication.

Abstract

Fossil fuels leaded the 21st century industrial revolution but caused some critical problems such as exhaustion of resources and global warming. Also, current power plants require too much high cost and long time for establishment and facilities to provide electricity. Thus, developing new power production systems with environmental friendliness and low-cost is critical global needs. There are some emerging energy harvesting technologies such as thermoelectric, piezoelectric, and triboelectric nanogenerators, which have great advantages on eco-friendly low-cost materials, simple fabrication, and various operating sources. Since the introduction of various energy harvesting technologies, many novel designs and applications as power suppliers and physical sensors in the world have been demonstrated based on their unique advantages. In this Special Issue, we would like to address and share basic approaches, new designs, and industrial applications related to thermoelectric, piezoelectric, and triboelectric devices which are on-going in Korea. With this Special Issue, we aim to promote fundamental understanding and to find novel ways to achieve industrial product manufacturing for energy harvesters.
