  2. 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 ...

  3. Particle size analysis - Wikipedia

    en.wikipedia.org/wiki/Particle_size_analysis

    Particle size analyzers are used also in biology to measure protein aggregation. Particle size distribution of antiviral vaccines subjected to cold-chain disruptions, analyzed by Dynamic Light Scattering (DLS) DLS is a particularly appreciated technique for the characterization of nanoparticles designed for drug delivery, such as vaccines.

  4. Particle size - Wikipedia

    en.wikipedia.org/wiki/Particle_size

    Particle size is a notion introduced for comparing dimensions of solid particles (), liquid particles (), or gaseous particles ().The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size).

    en.wikipedia.org/wiki/Particle_technology

    Particle velocity can be calculated using the Doppler frequency from any signal, while the phase difference between two detectors determines particle size. [ 3 ] Fraunhofer diffraction : When a particle is at least 10 times larger than the laser wavelength and the scattering angle is 30° or smaller, the light intensity distribution pattern can ...

    Pharmaceutical manufacturing is the process of industrial-scale synthesis of ... These variables may include the particle size distribution (including aggregates or ...

  7. Granulation - Wikipedia

    en.wikipedia.org/wiki/Granulation

    It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use. Less commonly, it involves shredding or grinding solid material into finer ...

  8. Micromeritics - Wikipedia

    en.wikipedia.org/wiki/Micromeritics

    It is thus the study of the fundamental and derived properties of individual as well as a collection of particles. The knowledge and control of the size of particles has importance in pharmacy and materials science. The size, and hence the surface area of a particle, can be related to the physical, chemical and pharmacological properties of drugs.

  9. De Brouckere mean diameter - Wikipedia

    en.wikipedia.org/wiki/De_Brouckere_mean_diameter

    Example showing the difference between D 50 and the De Brouckere Mean on a typical volume-weighted particle size distribution. The De Brouckere mean diameter is the mean of a particle size distribution weighted by the volume (also called volume-weighted mean diameter, volume moment mean diameter. [1] or volume-weighted mean size [2]). It is the ...
