Specific Surface Area Measurement by Air Permeability with Consideration for the Molecular Flow Effect [Translated]†

open access: diamondKONA Powder and Particle Journal, 2014
Because gas permeation through a powder bed is affected by molecular flow, applicability of the Kozeny-Carman equation, which neglects this effect, is limited to powders coarser than about 10 μm ...

Electrospinnability analysis of natural cellulose nanofibers for use in high-efficiency particulate matter capture based on rheological behaviors

open access: yesMaterials & Design, 2023
To aid the development of air filters with high-efficiency fine particulate matter (PM) capture properties, the electrospinnabilities of natural cellulose nanofibers, which considerably affect filter performance, were investigated via rheological ...
