Book excerpt: The fabrication of advanced electronic devices that operate on quantum effects requires the patterning of semiconductors on the scale of 50 A, which cannot be achieved by any of the currently available patterning technologies. This project pursued a novel approach: the fabrication of a self-assembling template which would allow the deposition of ordered arrays of germanium dots on silicon substrates, on length scales permitting the operation of quantum devices at room temperature. The template is the mesoporous silicate MCM-41, discovered by researchers at Mobil Chemical Corp. This material consists of highly ordered, two-dimensional, hexagonal arrays of very uniform pores in silicon dioxide, with diameters tunable from 20 A to over 100 A. If pore arrays of this material can be grown as thin films on silicon substrates, with the pores oriented normal to the substrate surface, the resulting structure will provide a template for the deposition of germanium dots. Germanium can then be deposited through the pores in the film and onto the silicon substrates by chemical or physical vapor deposition. The template film can then be etched away, leaving a hexagonally ordered array of germanium dots on the silicon substrate. Mesoporous silica films were grown on oxidized silicon substrates by acidic synthesis. The substrates were first patterned by optical lithography to produce vertical features with dimensions of the order of microns. The substrates were then coated with hydrophobic polymer monolayers to alter their surface energy. This monolayer was selectively removed from the horizontal surfaces of some of the substrates, leaving it only on the vertical surfaces of the patterned features. It was thought that the difference in surface energy between horizontal and vertical surfaces would induce the pores to align along the vertical surfaces.

Available in PDF, EPUB and Kindle. Book excerpt: Porous materials are of scientific and technological importance because of the presence of voids of controllable dimensions at the atomic, molecular, and nanometer scales, enabling them to discriminate and interact with molecules and clusters. Interestingly the big deal about this class of materials is about the “nothingness” within — the pore space. International Union of Pure and Applied Chemistry (IUPAC) classifies porous materials into three categories — micropores of less than 2 nm in diameter, mesopores between 2 and 50 nm, and macropores of greater than 50 nm. In this book, nanoporous materials are defined as those porous materials with pore diameters less than 100 nm.Over the last decade, there has been an ever increasing interest and research effort in the synthesis, characterization, functionalization, molecular modeling and design of nanoporous materials. The main challenges in research include the fundamental understanding of structure-property relations and tailor-design of nanostructures for specific properties and applications. Research efforts in this field have been driven by the rapid growing emerging applications such as biosensor, drug delivery, gas separation, energy storage and fuel cell technology, nanocatalysis and photonics. These applications offer exciting new opportunities for scientists to develop new strategies and techniques for the synthesis and applications of these materials.This book provides a series of systematic reviews of the recent developments in nanoporous materials. It covers the following topics: (1) synthesis, processing, characterization and property evaluation; (2) functionalization by physical and/or chemical treatments; (3) experimental and computational studies on fundamental properties, such as catalytic effects, transport and adsorption, molecular sieving and biosorption; (4) applications, including photonic devices, catalysis, environmental pollution control, biological molecules separation and isolation, sensors, membranes, hydrogen and energy storage, etc./a

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the current knowledge of two-dimensional oxide materials. The fundamental properties of 2-D oxide systems are explored in terms of atomic structure, electronic behavior and surface chemistry. The concept of polarity in determining the stability of 2-D oxide layers is examined, charge transfer effects in ultrathin oxide films are reviewed as well as the role of defects in 2-D oxide films. The novel structure concepts that apply in oxide systems of low dimensionality are addressed, and a chapter giving an overview of state-of-the-art theoretical methods for electronic structure determination of nanostructured oxides is included. Special emphasis is given to a balanced view from the experimental and the theoretical side. Two-dimensional materials, and 2-D oxides in particular, have outstanding behavior due to dimensionality and proximity effects. Several chapters treat prototypical model systems as illustrative examples to discuss the peculiar physical and chemical properties of 2-D oxide systems. The chapters are written by renowned experts in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the fundamental properties, preparation routes and applications of a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). Mesoporous silicas are amorphous inorganic materials which have silicon and oxygen atoms in their framework with pore size ranging from 2 to 50 nm. They can be synthesized from surfactants as templates for the polycondensation of various silicon sources such as tetraalkoxysilane. In general, mesoporous silica materials possess high surface areas, tunable pore diameters, high pore volumes and well uniformly organized porosity. The stable chemical property and the variable ability for chemical modification makes them ideal for many applications such as drug carrier, sensor, separation, catalyst, and adsorbent. Among such mesoporous silicas, in 1999, three groups in Canada, Germany, and Japan independently developed a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). The organic functional groups in the frameworks of these solids allow tuning of their surface properties and modification of the bulk properties of the material. The book discusses the properties of PMOs, their preparation, different functionalities and morphology, before going on to applications in fields such as catalysis, drug delivery, sensing, optics, electronic devices, environmental applications (gas sensing and gas adsorption), biomolecule adsorption and chromatography. The book provides fundamental understanding of PMOs and their advanced applications for general materials chemists and is an excellent guide to these promising novel materials for graduate students majoring in chemical engineering, chemistry, polymer science and materials science and engineering.

The description/summary is only for promotion (flyer, distribution channels), and will not be included in the book You can use the short text on the SI page for the description Nanovesicles are highly-promising systems for the delivery and/or targeting of drugs, biomolecules and contrast agents. Despite the fact that initial studies in this area were performed on phospholipid vesicles, there is an ever-increasing interest in the use of other molecules to obtain smart vesicular carriers focusing on strategies for targeted delivery. These systems can be obtained using newly synthesized smart molecules, or by intelligent design of opportune carriers to achieve specific delivery to the site of action. The drug/contrast agent-containing vesicles need to be directed to precise locations within the body to obtain desired magnitude and duration of the therapeutic or diagnostic effect. This spatial control in the delivery might open new avenues to modulate drug activity while avoiding side-effects and to optimize contrast agent properties while avoiding a broad distribution in the organism. However, delivering and targeting active substances into specific tissues and cells is still a challenge in designing novel therapeutic approaches against untreatable disorders, such as tumors and degenerative diseases.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on recent advances in nanostructured and nanophase materials and their applications. Nanostructured materials consist of domains of less than 100nm and include atom clusters and cluster assemblies, one- and two-dimensionally modulated layers and three-dimensional structures. The term 'nanophase' refers to structures comprised of domains or particles of a single material that are typically less than 100nm, whereas 'nanocomposite' refers to a composite of more than one nanophase. Nanoscale materials can be engineered as homogeneous or porous ceramics, metals, metal oxides, semiconductors, organic polymers, or as composite materials containing these components. This book brings together scientists from many disciplines to share and discuss advances in the field. Topics include: nanophase materials; nanocomposite materials; nanoporous materials; nanostructured materials; applications and properties of nanostructured materials; carbon nanotubes; nanostructured thin films and coatings; and theoretical and modeling studies of nanostructured materials.
