Nanotechnology - A Future Technology with Visions

    Nanotechnology is increasingly considered to be the future technology. Instead of "ever higher, ever wider" its motto is "ever smaller, ever faster". Nanotechnology provides access to the world of the smallest things. One nanometre is a millionth part of a millimetre. The diameter of a human hair is fifty thousand times bigger. The possible applications of this technology are immense. Future progress in nanotechnology will also determine the further development of future-oriented branches. The Federal Ministry of Research has presented a new overall strategy for this area.

Nanotechnology is dealing with research and the construction in the sphere of very small structures: one nanometre is one millionth of a millimetre. Nano (Greek: dwarf) includes research areas in animate and inanimate nature. Applications emerge in energy technology (fuel cells and solar cells), in environmental technology (materials cycles and disposal) or in information technology (new memories and processors) but also in the healthcare area. Nanotechnology is the umbrella term for the most different types of analysis and processing of materials which have one thing in common: Their size is one to one hundred nanometres (one nanometre is one millionth of a millimetre). Nanotechnology makes use of the special characteristics of many nanostructures. The mechanical, optical, magnetic, electrical and chemical characteristics of these very small structures do not only depend on their original material but very much also on their size and shape. A precondition for nanotechnology is the discovery of the possibilities of working with individual components of matter as well as the related growing understanding of the self-organization of these components.


Nanotechnology develops the basis for increasingly smaller data memories with increasingly larger storage capacity, for highly efficient filters for sewage treatment, for photovoltaic windows, for materials which can be used to build ultra-light engines and body parts in the automobile industry or for artificial joints which are better tolerated by the human body due to organic nano-surfaces.
Current situation

The industrial conquest of the nanometre dimension has already started. Similar to information technology, the study of the basic physics goes hand in hand with the development and the introduction on the market of first products. Nano-scale structuring in chip production or the development of new hard drives for computers has already become a standard procedure in electronics. However, the future competitiveness of the products of many other important industries in Germany, such as the chemical, pharmaceutical, automobile, information technology or optical industries, also depends on the development of the nanocosmos. Future progress in nanotechnology is decisive for the further development of these industries.

Nanotehnologija pruža neslućene mogućnosti tehnološkog napretka

14-10-2005
   

Stotine naučnika su ove sedmice bili u Hustonu u Texasu na Kongresu nanotehnologije koji je držao Rice University, gdje su se učesnici radili na razvoju minijaturnih mehanizama koji mogu promijeniti svijet

Svijet nanotehnologije je isuviše mali da bi se vidio golim okom, ali njegov potencijalni učinak je ogroman.

Nanotehnologija se bavi manipulacijom materije na nivou atoma. Istraživači su svoje napore usredsredili na upotrebu tehnologije za  poboljšanje medicinskih tretmana, proizvodnju bržih kompjutera i čvršćih a lakših materijala. Wade Adams, direktor Nanotehnološkog centra na Rice univerzitetu kaže da su minijaturne cijevi čiji su zidovi debljine samo jednog atoma nevjerovatno čvrste.

Wade Adams, Rice univerzitet:
Veliki  napor je uložen u razvoj  nano jedno-slojne cijevi ugljika, za koji predvidjamo da će biti najsnažniji materijal na svijetu.

Iako najveći dio tehnologije ostaje na eksperimentalnom nivou, Adams kaže se proizvodi nanotehnologije već pojavljuju.

Wade Adams:
U narednih nekoliko godina vidjećemo neke odlične proizvode koje u smislu materijala imaja mnogo bolja svojstva.  Mi već koristimo neka od tih svojstava kao na primjer njihovu električnu provodljivost.  Možete staviti desetinku ili stotinku procenta  nano cijevi u plastiku i time je učiniti provodnikom i koristiti ga da spriječite pražnjenja statičkog elektriciteta u ležištu  vašeg kompjutera.

Američke oružene snage, kao i Američki svemirski program, su vrlo zainteresovani za ovakve uredjaje.
Sivaram Arepelli , naučnik Svemirskog centra Johnson je bio na licu mjesta. On predvidja ogromne rezultate istraživanja ovih minijaturnih mehanizama.

Sivram Arepalli, Johnson Space Centar:
Možete napraviti strukture koje su mnogo čvršće i sa multifunkcionalnim materijalom. Ta struktura će stvoriti čvrstoću ako i energiju, može osjetiti i popraviti samu sebe...

Kompozitni materijali razvijeni kroz nanotehnologiju mogu se koristiti ne samo za svemirska vozila, nego i za pravljenje lakših i čvršćih automobila i aviona.
Naučnici koji su učestvovali u ovoj konferenciji kažu da su ovakvi skupovi izvrsna prilika za konkurentne univezitete i institucije da razmijene informacije i pomognu jedni drugima da izgrade budućnost baziranu na nanotehnologiji.
