Introduction Recently an emerging RF coil technology based on a new nanostructured material was introduced [1]. The nanomaterial can be macroscopically configured in a ribbon or string form and is comprised of a dense array of carbon nanotubes. The macroscopic configuration is mechanically robust and is held together densely by van der Waals forces. It was demonstrated in [1] that this material...

A non-contact and low-cost nanomaterial based fiber-optic sensor is developed for measuring large values of electric currents. The magnetic field, generated by the electric current, changes the refractive index of a liquid in which nanomaterial particles are suspended. The change of refractive index is converted to a change in the intensity of light transmitted in an evanescent field based fibe...

Nanotechnology is now applied to many industries, resulting in wide range of nanomaterial-containing products, such as electronic components, cosmetic, medicines, vehicles, and home appliances. Nanoparticles can be released throughout the life cycle of nanoproducts, including the manufacture, consumer use, and disposal, thereby involving workers, consumers, and the environment in potential expo...

An international symposium for nanosafety was held recently at the Nanyang Technological University in Singapore. Topics relating to understanding nanomaterial properties, tools, and infrastructure required for predicting hazardous outcomes, measuring nanomaterial exposure levels, systems approach for risk assessment and public's perception of nanotechnology were covered. The need for a multidi...

In recent years, it has become evident that it is necessary to systematically and accurately define particle characteristics in order to understand the potential toxicity of nanoparticles to biological systems. The properties that need to be emphasized are size, shape, dispersion, doping, aggregation, functionalization, physical and chemical properties, surface area, and surface chemistry. Rout...

Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The effect of carbon nanofiber dispersion in phenolic resins/carbon fabric composites was investigated. The dispersion efficiency in dif...

Tiny medicine refers to the development of small easy to use devices that can help in the early diagnosis and treatment of disease. Early diagnosis is the key to successfully treating many diseases. Nanomaterial-based biosensors utilize the unique properties of biological and physical nanomaterials to recognize a target molecule and effect transduction of an electronic signal. In general, the a...

For the past century, researchers have invested great efforts in the synthesis of materials with various shapes and sizes. We have developed a method to prepare what appear to be inorganic double helices of cryptomelane nanomaterial with the highest surface area ever reported for this class of materials. The synthesis is based on the oxidation of MnSO4 by permanganate ion in acidic conditions a...
