Nanofabrication in polymer matrices

Die einzigartige Struktur von MCM-41-Silicaten (im Bild schematisch dargestellt) bietet auserst attraktive Eigenschaften: einheitliche Porengrosen von mehr als 20 A, innere Oberflachen von mehr als 1000 m2 g−1 sowie eine weitreichende Ordnung der Poren. Die Forschung auf dem Gebiet der mit supramolekularen Templaten hergestellten mesoporosen Materialien hat zu Verbindungen gefuhrt, deren Zusammensetzungen sich uber einen weiten Bereich erstrecken, zu einer Vielzahl von Anwendungen dieser Materialien in der Katalyse und zu Moglichkeiten, ihre Morphologien besser zu steuern.

Synthese und Anwendungen von mit supramolekularen Templaten hergestellten mesoporösen Materialien

Nanoscale structures have been at the core of research efforts dealing with integration of nanotechnology into novel electronic devices for the last decade. For instance, the unique electrical and optical properties of nanowires, nanotubes and nanocables with vertical orientation, assembled in nanoscale arrays, have been used in many device applications such as sensors that hold the potential to augment brain functions. However, the challenge in creating nanowires/nanotubes or nanocables arrays based sensors lies in making individual electrical connections fitting both the features of the brain and of the nanostructures. This review discusses two of the most important applications of nanostructures in neuroscience. First, the current approaches to create nanowires and nanocable structures are reviewed to critically evaluate their potential of developing unique nanostructure based sensors to improve recording and device performance to reduce noise and the detrimental effect of the interface on the tissue. Second, the implementation of nanomaterials in neurobiological and medical applications will be considered from the brain augmentation perspective. Because the size of nanomaterials is of the same order of magnitude with that of biomolecules, these materials are valuable tools for nanoscale manipulation in a broad range of neurobiological systems. Novel applications for diagnosis and treatment of brain diseases such as multiple sclerosis, meningitis, stroke, epilepsy, Alzheimer disease, schizophrenia, and autism will be considered. Because the blood brain barrier (BBB) has a defensive mechanism in preventing nanomaterials arrival to the brain, various strategies to help them to passing through the BBB will be discussed. The nanostructures at the interface between nanotechnology and neuroscience will play a pivotal role not only in addressing the multitude of brain disorders but also to repair/augment brain functions.

Nanostructures: a platform for brain repair and augmentation.

Processing of mesoporous silica materials (MCM-41) from coal fly ash

The use of cationic surfactants as structure directing agents has resulted in the discovery of M41S, the first, ordered mesoporous molecular sieves. Herein we describe the ability of the surfactant molecules to interact with silicate counterions resulting in the formation of organosilicate-surfactant composite arrays which exhibit hexagonal, cubic or lamellar structure.

Designed Synthesis of Mesoporous Molecular Sieve Systems Using Surfactant-Directing Agents

The M41S family of materials represent the first mesoporous molecular sieves. This new family of materials with high pore volumes and surface areas exhibits an array of structures that are thermally stable inorganic analogs of organic, lyotropic liquid crystalline phases. The ability of the surfactant/aluminosilicate intermediate to assemble into stable extended structures results in mesoporous materials that are structurally diverse exhibiting hexagonal, cubic, and lamellar phases. The materials can be prepared with narrow pore size distributions at pore sizes ranging from 15 to greater than 100 A, varied elemental compositions and variable surface properties. This variability in physical properties has resulted in catalytic and sorption separation applications.
