  2. Photophoresis - Wikipedia

    en.wikipedia.org/wiki/Photophoresis

    The applications of photophoresis expand into the various divisions of science, thus physics, chemistry as well as in biology. Photophoresis is applied in particle trapping and levitation, [3] in the field flow fractionation of particles, [4] in the determination of thermal conductivity and temperature of microscopic grains [5] and also in the transport of soot particles in the atmosphere.

  3. Carbon nanotube - Wikipedia

    en.wikipedia.org/wiki/Carbon_nanotube

    A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range . They are one of the allotropes of carbon. Two broad classes of carbon nanotubes are recognized: Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000

  4. Carbon quantum dot - Wikipedia

    en.wikipedia.org/wiki/Carbon_quantum_dot

    Carbon quantum dots also commonly called carbon nano dots or simply carbon dots (abbreviated as CQDs, C-dots or CDs) are carbon nanoparticles which are less than 10 nm in size and have some form of surface passivation.

  5. Nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle

    The high surface area of a material in nanoparticle form allows heat, molecules, and ions to diffuse into or out of the particles at very large rates. The small particle diameter, on the other hand, allows the whole material to reach homogeneous equilibrium with respect to diffusion in a very short time.

  6. Single particle analysis - Wikipedia

    en.wikipedia.org/wiki/Single_particle_analysis

    The image processing is carried out using specialized software programs, often run on multi-processor computer clusters. Depending on the sample or the desired results, various steps of two- or three-dimensional processing can be done. In addition, single particle analysis can also be performed in an individual particle mode using an ICP-MS unit.

  7. Graphene - Wikipedia

    en.wikipedia.org/wiki/Graphene

    Graphene (/ ˈ ɡ r æ f iː n /) [1] is a carbon allotrope consisting of a single layer of atoms arranged in a honeycomb planar nanostructure. [2] [3] The name "graphene" is derived from "graphite" and the suffix -ene, indicating the presence of double bonds within the carbon structure.

  8. Photon - Wikipedia

    en.wikipedia.org/wiki/Photon

    The experimental upper limit on the photon mass [20] [21] is very small, on the order of 10 −50 kg; its lifetime would be more than 10 18 years. [22] For comparison the age of the universe is about 1.38 × 10 10 years. In a vacuum, a photon has two possible polarization states. [23]
