Functionalized Nanoscale Materials, Devices and Systems

Product Description

This book arises from the NATO Advanced Study Institute (ASI) titled “Functionalized Nanoscale Materials, Devices, and Systems for chem.-bio Sensors, Photonics, and Energy Generation and Storage” held in Sinaia, Romania in June 2007. It comprises a variety of invited contributions by highly experienced educators, scientists, and industrialists, and is structured to cover important aspects of the field, from underlying principles, synthesis routes, characterizations, applications, and detailed considerations of commercial viability. In addition, the book consists of a selection of contributed articles describing various aspects of their current research and development activities. Several related topics ranging from nanomaterial in chemical-biological sensors, to energy storage and generation devices, and to environmental protection and pollution remediation. Several top-down (attrition) and bottoms-up (self-assembly) approaches to prepare nanomaterials are discussed. In addition, several synthesis routes, viz. synthesis using new laser systems generating ultra-short (ns, ps, fs, and very recently, as pulses) with very high quality beams that allow very accurate focusing, provide unique tools for handling and processing nanomaterials in the form of nanocoatings, nanopowders, nanotubes, and other advanced structures are also included in the book. It will be of considerable interest and value to those already pursuing or considering careers in the field of nanostructured materials and nanotechnology, in general. It also serves as a valuable source of information for those interested in related aspects of the field, such as science and technology of thin film materials and devices.

Nano- and Biocomposites

Product Description

Advanced polymer-based nanocomposite materials continue to become increasingly popular and important for a wide range of engineering applications, as evidenced by continued government initiatives involving R&D and commercialization of these substances. In the race to exploit the unique mechanical, thermal, and electrical properties of nanocomposite materials, researchers must also address new challenges to predict, understand, and manage the potentially adverse effects they could have on human lives and the environment.

Nano- and Biocomposites focuses on the structural makeup of nanomaterials and their range of applications. It details the latest research in which biological applications of nanostructural resins have been conducted within in vitro and in vivo environments. Some of the applications explored in this book include:

• Tissue engineering and growth
• Mechanical and thermal stability enhancement of biocompatible polymers for artificial joints and scaffolding
• Thermal management for directed energy weapons, deicing, and electronics
• Structural performance for primary and secondary airframe structures, jet engines
• Electrical conductivity for lightning-strike protection, EMI, ESD, and energy storage
• Durability for chemical, wear, flame retardance, permeability
• Health monitoring for NDE certification, damage detection, and long-term degradation

This compilation of author contributions is divided into two sections—Nanostructured Polymer Composites and Nano-Bio Composites. It provides a basic understanding of nanomaterial and nanocomposite research to explain the fundamentals of how nanostructured fillers strengthen polymer-based materials. With an emphasis on how nano- and biocomposites are used to create new biomedical applications, the text also focuses on the crucial yet often-ignored potential toxicity impact of using nanostructured materials. It presents important guidelines and new insights to stimulate investigation of anticipated research in this fascinating new field. Researchers, scientists, and academics will appreciate this cutting-edge exploration of nanomaterials, biomaterials, and the ever-evolving world of nano-biomaterials.

Degradation of phenol by nanomaterial TiO”2 in wastewater

Product Description
This digital document is a journal article from Chemical Engineering Journal, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
The degradation of 100mg/L phenol solution under ultraviolet (UV) in the presence of TiO”2 and in the absence of it was analyzed with gas chromatography/mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC). After 12h of degradation, the products under the two conditions were both derivatized by MSTFA and TMIS, and then analyzed by GC-MS. The results show the main intermediates are the same. They are hydroquinone, resorcinol, catechol, 1,2,3-benzenetriol, (E)-2-butenedioic acid, 2-hydroxy-propaldehyde, glycerol, 3-hydroxy-propyl acid, and hydroxy-acetic acid. The chromatogram given by HPLC indicates that the presence of TiO”2 is not in favor of the degradation when the concentration of phenol is 100mg/L; its catalysis becomes evident when the concentration gets lower. Based on the intermediates, it can be proved that besides ?OH, ?H is also an important active free radical in the degradation.
