Prospects for development of nanotechnology in Poland are good. Technological gap between us and the countries most advanced in this area is relatively small. We also have a high level of research and industry interest in their results leads to be optimistic - believes prof. Christopher J. fillings from the Department of Materials Science and Engineering Warsaw University of Technology. At a recent seminar said CI scientist, among others about what is nanotechnology and what the consequences and the benefits it brings.
According to prof. Kurzydłowskiego, before our eyes today make up a kind of "revolution" in the area of \u200b\u200btechnology related to nanotechnologies, comparable to that which concerns the so-called. virtual techniques. The number of scientific publications and patents in nanotechologii from year to year is growing. As highlighted by the researcher, this is not a manifestation of nano-instantaneous fashion (although this also occurs because the research topics are "contagious"), but a consistent trend.
Nanotechnology is the production of materials with controlled structure at the nanometric scale, on the order of billionths of a meter (for example, in one nanometrze is composed of 10 atoms). This nano-particles, nano-fibers, nano-particle, nano-layers, nano-ageregaty, nano-composites. Their dimensions are comparable to the dimensions of biological structures - such as living cells. Obtained in the laboratory today, for example, carbon nanotubes have a diameter of 500 nanometers, which is the same as the diameter spider thread - explained speaker.
He noted the fact that the descent into such a small size brings with it various consequences.
One consequence is the need to consider the laws governing nanoświatem. Nano particles are so close together that we begin to interact each other. Become so insignificant, for example, the processes going on at the grain boundaries and in areas separating them - explained prof. Fillings. He added that in there too such as nanomaterials to changes in the distribution of magnetic spins, volume responsible (in the same volume can be to pack such a million times more nano-particles), strength, segregation of impurities and alloying elements.
According to the researcher, some of these processes, we can no longer use in practice, for example in the manufacture of molds (use of nano-powders eliminates the disadvantages of casting), production of durable aircraft engine turbine blades subjected to enormous temperatures and mechanical stress, sensors, materials conductive composites and epoxy resins. Over other materials, research is ongoing.
In Poland, advanced work in this area are conducted at several research centers, including in headed by prof. Kurzydłowskiego Department of Materials Design at the Department of Materials Science and Engineering PW. In research on new methods for obtaining nanomaterials department cooperates with the Institute of High Pressure Physics PAS.
Prof. Kurzydłowski recalled that on September 14 this year, Warsaw University of Technology will host the first in Poland, a large forum of people dedicated to science and business of nanotechnology. It will aim to include show the nano-products and an indication of the benefits of nanotechnology in various areas of life.
