Nanoparticle synthesis allows particle size and shape to be tailored to end applications
November 30, 2005
Nanomaterials are increasingly gaining the attention of not only the scientific community, but also the public due to their unique properties which endear them to new and exciting applications. These special properties can vary markedly from those of the analogous bulk materials. The physical and chemical properties of the nanomaterials tend to be exceptionally closely dependent on their size and shape or morphology. As a result, materials scientists are focusing their efforts on developing simple and effective methods for fabricating nanomaterials with controlled size and morphology and hence, tailoring their properties. In this paper published in AZojomo*, Pennsylvania State University researchers Qingyi Lu, Feng Gao, Dongsheng Li and Sridhar Komarneni, synthesized and characterized nanomaterials of controlled size and shape. These materials have potential to be used in several different applications including interconnects in electronic devices with super functions and bio-molecule separations. The methods they employed included the microwave-assisted solvothermal or biomolecule-assisted hydrothermal methods.
By altering the synthesis methods, the researchers were able to create a range of different nanoparticles. These synthesized nanomaterials varied from uniformly sized spherical nanoparticles, nanowires, nanorods to arrays with oriented mesochannels.
The study shows that conventional and microwave assisted hydro or solvothermal methods are highly suited for the synthesis of nanomaterials of controlled size and shape under environmentally benign conditions for arrange of different applications.

Nanomaterials: An Introduction to Synthesis, Properties and Applications
by Dieter Vollath (Author)
This first full-colored introduction to nanomaterials and nanotechnology addresses in particular the needs of engineers who have to know the special phenomena and potentials, without going into too much scientific detail of the physics and chemistry involved. Based on the author's own successful courses, Nanomaterials: An Introduction to Synthesis, Properties and Applications shows how to produce nanomaterials and use them in engineering applications for novel products. Following an introduction, the text goes on to treat synthesis, characterization techniques, thermal, optical, magnetic and electronic properties, processing and, finally, emerging applications. Engineers looking for a sound introduction to the "nano world" will find this...

Nanomaterials Handbook
by Yury Gogotsi (Editor)
Even before it was identified as a science and given a name, nanotechnology was the province of the most innovative inventors. In medieval times, craftsmen, ingeniously employing nanometer-sized gold particles, created the enchanting red hues found in the gold ruby glass of cathedral windows. Today, nanomaterials are being just as creatively used to improve old products, as well as usher in new ones. From tires to CRTs to sunscreens, nanomaterials are becoming a part of every industry. The Nanomaterials Handbook provides a comprehensive overview of the current state of nanomaterials. Employing terminology familiar to materials scientists and engineers, it provides an introduction that delves into the unique nature of nanomaterials. Looking at the quantum effects that come into...

Nanomaterials: Mechanics and Mechanisms
by K.T. Ramesh (Author)
The enabling science in much of nanotechnology today is the science of nanomaterials; indeed in the broadest sense, nanotechnology would not be possible without nanomaterials. Nanomaterials: Mechanics and Mechanisms seeks to provide an entrè into the field for mechanical engineers, material scientists, chemical and biomedical engineers and physicists. The objective is to provide the reader with the connections needed to understand the intense activity in the area of the mechanics of nanomaterials, and to develop ways of thinking about these new materials that could be useful to both research and application. The book covers all of the fundamentals of the mechanical properties of materials in a highly readable style, and integrates most of the literature on the emerging field of...

Introduction to Nanoscience
by Gabor L. Hornyak (Author), H.F. Tibbals (Author), Joydeep Dutta (Author), Anil Rao (Author)
Tomorrow’s nanoscientist will have a truly interdisciplinary and nano-centric education, rather than, for example, a degree in chemistry with a specialization in nanoscience. For this to happen, the field needs a truly focused and dedicated textbook. This full-color masterwork is such a textbook. It introduces the nanoscale along with the societal impacts of nanoscience, then presents an overview of characterization and fabrication methods. The authors systematically discuss the chemistry, physics, and biology aspects of nanoscience, providing a complete picture of the challenges, opportunities, and inspirations posed by each facet before giving a brief glimpse at nanoscience in action: nanotechnology.
