  2. Buying Time – Using Nanotechnologies and Other Emerging Technologies For A Sustainable Future.Thomas Vogt - 2010 - In U. Fiedeler (ed.), Understanding Nanotechnology. IOS Press. pp. 43-60.
    Abstract: Science and emerging technologies should not be predominantly tasked with furnishing us with more sustainable societies. Continuous short-term technological bail outs without taking into account the longer socio-cultural incubation times required to transition to ‘weakly sustainable’ economies squander valuable resources and time. Emerging technologies need to be deployed strategically to buy time in order to have extended political, social and ethical discussions about the root-causes of unsustainable economies and minimize social disruptions on the path towards global sustainability. Keywords: (...); nanotechnology; expanded materials design space; dematerialization; sustainability; permanent resource crises . (shrink)

  3. Nanoantennas distribution of alternating current (with a wavelength that is ۱۰۰ times smaller than the wavelength of free space).Afshin Rashid - 2024 - Authorea 12.
    In general, in order to receive the electromagnetic wave in the space, the dimensions of the antenna must be in the order of the wavelength of the input to its surface. Due to the very small dimensions of nano sensors, nano antennas need to have a very high working frequency to be usable. The use of graphene helps to solve this problem to a great extent. The speed of propagation of waves in CNTs and GNRs can be 100 times lower (...)

    Investigating The Catalysis of Nano Particles in The Process of Simulating Carbon Nanotubes and CNTs.Afshin Rashid - 2024 - Elsevier Bv , Engrn Electrical Engineering Ejournal, 261.
    Nanoparticles can also be used as catalysts due to their high surface area. Of course, catalytic properties also occur in certain dimensions like magnetic properties. In other words, nanoparticles usually have catalytic properties if their specific surface is between 100 and 400 square meters per gram. Therefore, among nanoparticles with a specific volume, a nanoparticle with a larger surface area shows better catalytic properties. An example of nanoparticles that act as catalysts where various substances are placed on their surface and (...)

    The Wavelength of The Output Beam and The Wavelength of The Output Beam of Nano Laser.Afshin Rashid - 2024 - Elsevier Bv 7.
    The division is based on the wavelength of the output beam and the wave- length of the output beam of the wide range nano laser. According to this and the wavelength, the types of nano lasers include infrared, visible and ultraviolet lasers, for example, the nano laser produces a beam with a wavelength of about 858.32 X-rays, the wavelength of a solid nano laser is between 9.6 and 10.6 It is a microme- ter. This is because the wavelength of liquid (...)

  7. Humanities’ metaphysical underpinnings of late frontier scientific research.Alcibiades Malapi-Nelson - 2014 - Humanities 214 (3):740-765.
    The behavior/structure methodological dichotomy as locus of scientific inquiry is closely related to the issue of modeling and theory change in scientific explanation. Given that the traditional tension between structure and behavior in scientific modeling is likely here to stay, considering the relevant precedents in the history of ideas could help us better understand this theoretical struggle. This better understanding might open up unforeseen possibilities and new instantiations, particularly in what concerns the proposed technological modification of the human condition. The (...)

    Scanning Tunneling Microscope (STM) or Scanning Probe Nano Lithography or (SPL) in the Range (Below 20 Nanometers).Afshin Rashid - 2024 - Elsevier Bv 76.
    The use of AFM for scanning probe lithography also suffers from power-related problems, but it is better suited than STM for this task due to the less stringent requirements of the technique: no very high vacuum conditions. , conductive surface or very good tip-to-sample distance control is required. Scanning probe nanolithography based on AFM can be performed through different mechanisms and offers a wide range of possibilities . Therefore, the AFM tip can produce localized changes in the composition, height, or (...)

  9. Stoljeće rearanžiranja: nanoznanost i globalno društvo.Nijaz Ibrulj - 2004 - Pregled 1 (3/4):55-70.
    Esej "Stoljeće rearanžiranja: nanoznanost i globalno društvo", dovodi u vezu modernu znanost (nanoznanost) i moderno društvo (globalno društvo) kroz odnos nanotehnologizacije i globalizacije kao najvažnijih procesa jedne mreže fenomena koji se dotiču na području tehničkih i društvenih znanosti. Autor karakterizira 21. stoljeće kao stoljeće rearanžiranja u kojem znanost i filozofija funkcioniraju sa zajedničke osnove koja je holistička i pragmatička. Komparacijom novih tehničkih metoda u znanostima o materijalima i novih procesa u društvenoj ontologiji autor stavlja u odnos dva pristupa i dvije (...)
