Mesothelioma has long been linked to the inhalation and exposure to asbestos fibers and dust, so when scientists uncovered an additional potential cause for this incurable form of lung cancer, the unthinkable became a reality.
According to researchers based out of the Woodrow Wilson International Centre for Scholars in Washington D.C., the early 90′s development of carbon nanotubes has been an amazing feat for technological applications, however, it has not gone without its price. Specifically, carbon nanotubes may be causing harm to the human body in the form of mesothelioma cancer.
If the carbon nanotubes are introduced into the wrong environment, the development of lesions and inflammation of the lungs occurs – symptoms similar to that of mesothelioma cancer and asbestos exposure. Animals that were exposed to carbon nanotubes was how the researchers discovered the link. Dr. Andrew Maynard, who published a study in the journal Nature Nanotechnology, described the use of nanotubes and the potential link to mesothelioma cancer. The ability for nanotubes to conduct heat and electricity is what is driving their use, he said.
Nanotechnology is very diverse, ranging from novel extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials with dimensions on the nanoscale, even to speculation on whether we can directly control matter on the atomic scale.
Although nanotechnology is a relatively recent development in scientific research, the development of its central concepts happened over a longer period of time.
Photovoltaic (PV) is the field of technology and research related to the application of solar cells for energy by converting sun energy (sunlight or sun ultra violet radiation) directly into electricity. Due to the growing demand for clean sources of energy, the manufacture of solar cells and photovoltaic arrays has expanded dramatically in recent years.
Polysaccharides widely found in nature. More specifically, the nature product annually a million tons of biomass and the polysaccharides represent, in quantity, the majority of this biomass. They are constituents of plants (cellulose) and used as energy reserves (starch). Polysaccharides can also perform special functions, such as protective coatings pozycjonowanie stron for bacteria and other cells.
Polysaccharides are generally chemically inert, they are all non-toxic and do not cause allergies.
Polysaccharides are ideally suited to the manufacture of water-based sacrificial coatings because they can easily create a film (film-forming property). Related polysaccharides form a “gel”, this means that large amounts of water (generally over 90%) are trapped in a three-dimensional network, produced by the polysaccharide. This gel can, after a period of very rapid drying, losing much of its water, thus forming a protective film. This film, extremely thin, is not visible to the naked eye and is perfectly permeable to water vapor.
