This book was released on 2017-07-14 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoparticles have received much attention recently due to their use in cancer therapy. Studies have shown that different metal oxide nanoparticles induce cytototoxicity in cancer cells. Drug delivery systems are designed to achieve drug therapeutic index and enhance the efficacy of controlled drug release targeting with specificity and selectivity by successful delivery of therapeutic agents at the desired sites without affecting the non-diseased neighbouring cells or tissues. In this work, nano-titanium dioxide, as anatase phase, was obtained by the sol-gel method with a cleaner technology a bio-extract obtained from the plant Artemisia pallens containing poly alcohols- used as a solvent, the structural, optical, particle size and the morphological properties of TiO2 nanoparticles were analyzed using x-ray diffraction data, scanning electron microscope. The green TiO2 nanoparticles had a bandgap of 3.2 eV. The fourier transformer infra red spectroscopy (FT-IR) shows a single band attributed to TiO2 using the simple aqueous based organic solvent free approach is further used as nano carriers for drug delivery system. Also we have developed and demonstrated a bio-based titanium dioxide that can be loaded with anticancer drug and selectively deliver it to cancer cells with high specificity by achieving the effective cervical cancer cell death without inducing specific toxicity. The study showed that the DOX loaded TiO2 nanocrystals has promising applications in delivery of anticancer drugs.

Download or read book Composites and Nanocomposites written by A. K. Haghi and published by CRC Press. This book was released on 2013-03-01 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new book provides a solid understanding of the recent developments in the field of composites and nanocomposites. It explains the significance of the new fillers, such as graphene and arbon nanotubes in different matrix systems. The application of these materials in biological and others fields also makes this book unique. This detailed study of nanocomposites, their structure, processing and characterization will be of value in all walks of engineering life. The book covers the following topics: • polymer matrix composites • ceramic matrix composites • carbon matrix composites • wood-based composites • biocomposites • ecocomposites • nanocomposites • processing • properties • fracture and damage mechanics • durability • and more Composite materials are solids that contain two or more distinct constituent materials or phases, on a scale larger than the atomic. The term “composite” is usually reserved for those materials in which the distinct phases are separated on a scale larger than the atomic, and in which properties such as the elastic modulus are significantly altered in comparison with those of a homogeneous material. Composites have properties that cannot be achieved by either of the constituent materials alone. Composites are becoming more and more important as they can help improve our quality of life. Composites are put into service in flight vehicles, automobiles, boats, pipelines, buildings, roads, bridges, and dozens of other products. Researchers are finding ways to improve other qualities of composites so they may be strong, lightweight, long-lived, and inexpensive to produce. The science and engineering of composites and nanocomposites draws on traditional characterization and processing technologies. Research describing structures containing nanoparticles seems to rely on methods that are being pushed to the limit of resolution. Preparation of nanocomposites also poses very real processing challenges. The list of questions about the fabrication, characterization, and use of nanocomposites is long despite massive financial and intellectual investment. The magnitude of the effects these small particles impart to the bulk properties of a composite are great enough that the science is likely to continue to grow in importance.

Book excerpt: Research for the development of more efficient photocatalysts has experienced an almost exponential growth since its popularization in early 1970’s. Despite the advantages of the widely used TiO2, the yield of the conversion of sun power into chemical energy that can be achieved with this material is limited prompting the research and development of a number of structural, morphological and chemical modifications of TiO2 , as well as a number of novel photocatalysts with very different composition. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a systematic account of the current understanding of the relationships between the physicochemical properties of the catalysts and photoactivity. The already long list of photocatalysts phases and their modifications is increasing day by day. By approaching this field from a material sciences angle, an integrated view allows readers to consider the diversity of photocatalysts globally and in connection with other technologies. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a valuable road-map, outlining the common principles lying behind the diversity of materials, but also delimiting the imprecise border between the contrasted results and the most speculative studies. This broad approach makes it ideal for specialist but also for engineers, researchers and students in related fields.
