  2. History of nanotechnology - Wikipedia

    en.wikipedia.org/wiki/History_of_nanotechnology

    [23] [24] The first observations and size measurements of nanoparticles had been made during the first decade of the 20th century by Richard Adolf Zsigmondy, winner of the 1925 Nobel Prize in Chemistry, who made a detailed study of gold sols and other nanomaterials with sizes down to 10 nm using an ultramicroscope which was capable of ...

  3. Nanomaterials - Wikipedia

    en.wikipedia.org/wiki/Nanomaterials

    Nanomaterials can also be used in three-way-catalyst applications, which have the advantage of controlling the emission of nitrogen oxides (NO x), which are precursors to acid rain and smog. [46] In core-shell structure, nanomaterials form shell as the catalyst support to protect the noble metals such as palladium and rhodium. [47]

  4. Nanotechnology - Wikipedia

    en.wikipedia.org/wiki/Nanotechnology

    Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.

  5. Outline of nanotechnology - Wikipedia

    Richard Feynman - gave the first mention of some of the distinguishing concepts in a 1959 talk, entitled There's Plenty of Room at the Bottom; Robert Freitas - nanomedicine theorist; Andre Geim - Discoverer of 2-D carbon film called graphene; Sumio Iijima - discoverer of carbon nanotube; Harry Kroto - co-discoverer of buckminsterfullerene

  6. Applications of nanotechnology - Wikipedia

    en.wikipedia.org/wiki/Applications_of_nanotechnology

    Nanotechnology's ability to observe and control the material world at a nanoscopic level can offer great potential for construction development. Nanotechnology can help improve the strength and durability of construction materials, including cement, steel, wood, and glass. [9] By applying nanotechnology, materials can gain a range of new ...

  7. Nanochemistry - Wikipedia

    en.wikipedia.org/wiki/Nanochemistry

    Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...

  8. Nanomanufacturing - Wikipedia

    en.wikipedia.org/wiki/Nanomanufacturing

    Nanomanufacturing refers to manufacturing processes of objects or material with dimensions between one and one hundred nanometers. [15] These processes results in nanotechnology, extremely small devices, structures, features, and systems that have applications in organic chemistry, molecular biology, aerospace engineering, physics, and beyond. [16]

  9. Magnetic nanoparticles - Wikipedia

    en.wikipedia.org/wiki/Magnetic_nanoparticles

    Ferrite nanoparticles or iron oxide nanoparticles (iron oxides in crystal structure of maghemite or magnetite) are the most explored magnetic nanoparticles up to date.Once the ferrite particles become smaller than 128 nm [22] they become superparamagnetic which prevents self agglomeration since they exhibit their magnetic behavior only when an external magnetic field is applied.
