  • permits
  • This measured pressure permits obtaining the pore diameter, which is calculated by using the Young-Laplace formula P= 4*γ*cos θ*/D in which D is the pore size diameter, P is the pressure measured, γ is the surface tension of the wetting liquid and θ is the contact angle of the wetting liquid with the sample.

  • volume
  • Filter paper is mostly used because even a small piece of filter paper will absorb a significant volume of liquid The raw materials are different paper pulps. (wikipedia.org)
  • structure
  • After the bulk structure is assembled, the surfactant is removed, leaving pores, or channels, embedded in the material framework. (wikipedia.org)
  • The pore structure is formed by a syndetic channel system and has a specific surface from 10 to 300 m²/g. (wikipedia.org)
  • usually
  • A microfilter with pore size 0.2 m will usually effectively remove microorganisms in the processing of biologics, viruses must be removed, requiring the use of Nano filters with a smaller pore size (20-50 nm) are used. (emailwire.com)
  • Evaporation-induced self-assembly usually causes random alignment of the material pores. (wikipedia.org)
  • production
  • The device's tiny needles puncture the skin, which stimulates new collagen formation in the skin as well as the production of skin-tightening agents hyaluronic acid and elastin. (skininc.com)
  • Selective Laser Melting (SLM) enables the production of any geometry and was used for implant production with 250-µm pore size. (mdpi.com)
