The field of nanotechnology has been undergoing tremendous development in the recent decade. Nanotechnology is the ability to work at the atomic, molecular, supramolecular levels (on a scale of~ 1-100nm) in order to understand, create and use material structures
Patenting nanotechnology
free download
First, patent law seeks to foster and reward invention. Second, it promotes disclosure of inventions to stimulate further innovation and to permit the public to practice the invention once the patent expires. Third, the stringent requirements for patent protection seek to
Role of surfactants in nanotechnology and their applications
free download
Surfactants are characterized by the essential features that we saw in sodium oleate. A surfactant molecule has a hydrophilic (water-loving) head and a long hydrophobic (water- hating or oil-loving) tail. For this reason, we often describe surfactants is being amphiphilic

Implications of nanotechnology applications: using genetics as a lesson
free download
As society becomes more comfortable discussing genetics and its related ethics, a new technology is blossoming in the background. Nanotechnology speak the same societal language as does genetics, in that both technological movements involve tiny science and
Nanotechnology and its applications in veterinary and animal science
free download
Nanotechnology has a tremendous potential to revolutionize agriculture and livestock sector. It can provide new tools for molecular and cellular biology, biotechnology, veterinary physiology, animal genetics, reproduction etc. which will allow researchers to handle The nanotechnology revolution has been possible because scientists are able to explore and work at the nanoscale, a scale corresponding to dimensions between 1 and 100 nm. In Chap. 1 we describe how it is possible to see and move atoms and more generally to
Is nanotechnology too broad to practise
free download
Nanotechnology stands alone for one reason in particular: it is extraordinarily broad. That breadth allows nanotechnology to bring together formerly separate fields of study to maximize the strengths and utility of each. It has also enhanced the education of a new
