  2. Particle size - Wikipedia

    en.wikipedia.org/wiki/Particle_size

    In materials science and colloidal chemistry, the term colloidal particle refers to a small amount of matter having a size typical for colloids and with a clear phase boundary. The dispersed-phase particles have a diameter between approximately 1 and 1000 nanometers .

  3. Particle size analysis - Wikipedia

    en.wikipedia.org/wiki/Particle_size_analysis

    Particle size analysis, particle size measurement, or simply particle sizing, is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.

  4. Particle - Wikipedia

    en.wikipedia.org/wiki/Particle

    In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. [ 1 ] [ 2 ] They vary greatly in size or quantity, from subatomic particles like the electron , to microscopic particles like atoms and molecules ...

  5. Dispersion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(chemistry)

    Oxide dispersion-strengthened alloy (ODS) is an example of oxide particle dispersion into a metal medium, which improves the high temperature tolerance of the material. Therefore these alloys have several applications in the nuclear energy industry, where materials must withstand extremely high temperatures to maintain operation.

  6. List of particles - Wikipedia

    en.wikipedia.org/wiki/List_of_particles

    A WISP (weakly interacting slender particle) is any one of a number of low mass particles that might explain dark matter (such as the axion) A GIMP (gravitationally interacting massive particle) is a particle which provides an alternative explanation of dark matter, instead of the aforementioned WIMP

  7. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations. The log-hyperbolic distribution was proposed by Bagnold and Barndorff-Nielsen [9] to model the particle-size distribution of naturally occurring sediments. This ...

  8. Nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Nanoparticle

    The particle deformation can be measured by the deflection of the cantilever tip over the sample. The resulting force-displacement curves can be used to calculate elastic modulus. [75] However, it is unclear whether particle size and indentation depth affect the measured elastic modulus of nanoparticles by AFM. [75]

  9. Particle technology - Wikipedia

    en.wikipedia.org/wiki/Particle_technology

    Particle technology is the science and technology of handling and processing particles and powders. It encompasses the production, handling, modification, and use of a wide variety of particulate materials, both wet and dry. Particle handling may include transportation and storage. Particle sizes range from nanometers to centimeters.
