  • porosity
  • By varying the sample height, and hence the "porosity" of the bed, average surface area and particle size can be determined as a function of pressure rop and flow rate in accordance with the Carmen equation. (micromeritics.com)
  • With porous building blocks, controlling the link between porosity, particle size and mechanical properties is essential to the integrity of the system for any application," Shahsavari said. (eurekalert.org)
  • zeta
  • The NanoBrook Omni instrument offers a single powerful and accurate solution for particle sizing and zeta potential analysis. (genengnews.com)
  • In other words, zeta potential is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle. (horiba.com)
  • Established in the late 1960s, Brookhaven Instruments pioneered modern techniques in characterizing nanoparticles, proteins, and polymers using light scattering techniques such as dynamic, static, electrophoretic, and phase analysis for: particle size, zeta potential, molecular mass and absolute molar mass analysis.

  • Distributions
  • For particle size distributions the median is called the D50 (or x50 when following certain ISO guidelines). (horiba.com)
  • Since the primary result from laser diffraction is a volume distribution, the default D50 cited is the volume median and D50 typically refers to the Dv50 without including the v. This value is one of the easier statistics to understand and also one of the most meaningful for particle size distributions. (horiba.com)
  • BI-XDC-X-Ray Disk Centrifuge, provides both centrifugal and gravitational sedimentation with an X-ray technology to give error free, fast and accurate high-resolution size distributions across the "one-micron" transition region. (wikipedia.org)
  • silicate
  • HOUSTON -- (Dec. 18, 2017) -- Porous particles of calcium and silicate show potential as building blocks for a host of applications like self-healing materials, bone-tissue engineering, drug delivery, insulation, ceramics and construction materials, according to Rice University engineers who decided to see how well they perform at the nanoscale. (eurekalert.org)
  • This means that larger submicron calcium-silicate particles are tougher and more flexible compared with smaller ones, making them more damage-tolerant," he said. (eurekalert.org)
  • suspension
  • Commercial suspensions may be formulated to keep particles in suspension without sedimenting to the bottom. (horiba.com)
  • The slurry usually consists of abrasive boron carbide, aluminum oxide or silicon carbide particles in a suspension of water (20 to 60% by volume). (wikipedia.org)
  • Abstract
  • In all methods the size is an indirect measure, obtained by a model that transforms, in abstract way, the real particle shape into a simple and standarized shape, like a sphere (the most usual) or a cuboid (when minimum bounding box is used), where the size parameter (ex. (wikipedia.org)
  • velocity
  • The apparatus may further comprise light beams and light detecting means between the exit of the charging chamber and the collector electrode, for determining particle terminal velocity as it exits the charging chamber. (freepatentsonline.com)
  • discharge
  • The relationships between particle size of river sediments and the variation in stream discharge are studied. (asce.org)
  • A significant finding is presented which shows that the particle size of suspended and bed sediments remains relatively constant with variation in stream discharge. (asce.org)
  • Variation
  • The results of a study carried out to determine the variation of both bed material and suspended sediment particle size for differing flow conditions is presented. (asce.org)
  • tendency
  • There was no consistent effect of speed on particle size in this group of cars, but there was a slight tendency toward larger particle sizes as the load increased. (sae.org)
  • The smaller size of the Cl− ions causes a greater tendency to diffuse into the C-S-H membrane. (wikipedia.org)
  • light
  • The BI-MwA is a multiangle light scattering detector suitable for Size-exclusion chromatography(SEC), Gel permeation chromatography (GPC) or stand alone use. (wikipedia.org)
