Carbon Nanomaterials in Clean Energy Hydrogen Systems

Product Description

The energy arteries of the corporate body of mankind are still fed mainly by fossil fuels; but they are in danger of running dry soon unless new energy sources are made available.

One of the most important as well as the most ecologically pure power source is hydrogen, that constitutes the heart of hydrogen power engineering and considered as a future alternative to fossil power sources.

The chemistry of carbon nanomaterials and hydrogen materials science will play an important role in hastening the conversion to the Hydrogen Energy System.

In this connection the research and application of materials capable of interacting actively with hydrogen, its accumulating and storing will be of the utmost significance. This is of particular actuality for creation of mobile energy sources both for mobile telephones and for hybrid electric cars that are developed by all large car manufacturers of the world. In this connection the hydrogen capacity of carbon nanostructural materials, such as fullerenes, nanotubes, nanofibers and other nanostructures, has aroused a special interest of researchers.

Hydriding metals, alloys, nanocarbon and composite materials can store hydrogen safely at relatively low pressures and temperatures. Very many other applications are also possible – such as heating and cooling, waste heat storage, pumping, pressurizing, heat-pumping, hydrogen purifying, deuterium separation, electricity production, etc.

As a source of ‘clean’ energy, hydrogen is also going to be the permanent answer to another global problem caused by utilization of fossil fuels, such as the greenhouse effect, climate change, acid rains, ozone layer depletion, pollution and oil spills.

Interface Controlled Organic Thin Films

Product Description

Organic semiconductors are a central topic of advanced materials research. The book is aiming at bridging the gap between the development and production of devices and basic research on thin film characterisation using cutting-edge techniques in surface and interface science. Topics involve organic molecular-based sensors; interfaces in organic diodes and transistors; mobility in organic field effect transistors and space charge problems; integration of optoelectronic nanostructures; nonlinear optical properties of organic nanostructures; the wetting layer problem; how to get from functionalized molecules to nanoaggregates; optical, electrical and mechanical properties of organic nanofibers as well; as near field investigations of organic thin films.

An Introduction to Electrospinning and Nanofibers

Product Description
The research and development of nanofibers has gained much prominence in recent years due to the heightened awareness of its potential applications in the medical, engineering and defense fields. Among the most successful methods for producing nanofibers is the electrospinning process. In this timely book, the areas of electrospinning and nanofibers are covered for the first time in a single volume. The book can be broadly divided into two parts: the first comprises descriptions of the electrospinning process and modeling to obtain nanofibers while the second describes the characteristics and applications of nanofibers. The material is aimed at both newcomers and experienced researchers in the area.

Fabrication of Pt/C Nanofiber Electrode for Fuel Cell Application

Product Description
Triethylamine catalyst was used to increase the molecular weight of poly(amic acid). In electrospinning, diameter of PAA nanofibers was controlled by molecular weight of poly(amic acid) and concentration of poly(amic acid)/N-N dimethylformamide solution. The diameters of polyimide based carbon nanofibers reached to a minimum value of around 100 nm. The conductivity of the carbon nanofiber papers increased with the decreasing of fiber diameters, while the mechanical strength of polyimide and carbon nanofiber paper was diameter independent. Further more, Pt was successfully impregnated in carbon nanofiber. Reduction accompanied with carbonization in Ar gas at up to 1000 degree C produced small and well-dispersed Pt nanoparticles (3-5 nm). Carbon dioxide treatment exhibited the effective ability of removal of carbonaceous overlayers to promise a potential enhancement Pt catalyst activity. The reduction rate of Pt ion is different at heating rate of 2 and 5 degree C/min. Thus, the heating rate and time at high temperature strongly affected Pt nanoparticle size.

Continuous Carbon Nanofibers: Prepared from Electrospun Polyacrylonitrle Precursor Fibers

Product Description
The utilization of materials for the preparation of fibers and textiles began at the beginning of civilization and extended until the 20th centruy when steam driven machinery revolutionized the mechanical operations of spinning and weaving. Carbon fibers were first produced by Edison in the late 19th century; Edison found that regenerated cellulose (rayon) could be converted into carbon filaments for use in incandescent lamps. Electrospinning was first patented in 1902; electrospinning is a fiber spinning technique that relies on electrostatic forces to produce fibers in the nanometer to micron diameter range. The electrsopinning process of fiber production is examined in regards to the preparation of continuous Polyacrylonitrile (PAN) nanofibers with the purpose of preparing carbon nanofibers for the reinforcement of thin films and nanocomposites. The mechanical properties and reinforcing behavior of nanofibers are expected to differ significantly from their conventional counterparts; the strength of a carbon filament increases as the diameter decreases. The research should be especially useful to beginning and experienced researchers in the the field of nanomaterials.
