Green Metal Nanoparticles


Book Description

This groundbreaking book uniquely focuses on the exploration of the green synthesis of metal nanoparticles and their characterization and applications. Metal nanoparticles are the basic elements of nanotechnology as they are the primary source used in the design of nanostructured devices and materials. Nanomaterials can be manufactured either incidentally, with physical or chemical methods, or naturally; and the high demand for them has led to their large-scale production by various toxic solvents or high energy techniques. However, due to the growing awareness of environmental and safety issues, the use of clean, nontoxic and environment-friendly ways to synthesize metal nanoparticles has emerged out of necessity. The use of biological resources, such as microbes, plant parts, vegetable wastes, agricultural wastes, gums, etc., has grown to become an alternative way of synthesizing metal nanoparticles. This biogenic synthesis is green, environmentally friendly, cost-effective, and nontoxic. The current multi-authored book includes recent information and builds a database of bioreducing agents for various metal nanoparticles using different precursor systems. Green Metal Nanoparticles also highlights different simple, cost-effective, environment-friendly and easily scalable strategies, and includes parameters for controlling the size and shape of the materials developed from the various greener methods.

Ceramic nanocomposites


Book Description

Ultra-thin films can be coated on primary fine particles without significant aggregation by atomic layer deposition (ALD) in a fluidized bed reactor. Precursor doses can be delivered to the bed of particles sequentially and, in most cases, can be utilized at nearly 100% efficiency without precursor breakthrough and loss, with the assistance of an inline downstream mass spectrometer. A multitude of applications can be addressed in a competitive fashion using fine particles that have been surface-modified using ALD in scalable, high-throughput unit operations. Several examples of the applications of conformal ALD coatings have been discussed, including oxidation-resistant metals or ceramics, coatings that enable biomedical applications including tissue engineering, and corrosion-resistant particles for next-generation batteries, capacitors or fuel cells. It is expected that the technology of thin film coating by particle ALD will play a major role in the field of advanced materials.
