Nanoporous Membrane for Immunoprotection Biofilter

Next-Generation Nanoporous PTFE Membrane

Sumitomo Electric Industries, Ltd. invented a technique to make polytetrafluoroethylene (PTFE) porous using PTFE stretching technology, which was patented in 1962.(1) Drawing on the technique, the company has subsequently released various porous PTFE products such as filters and hollow fiber products under the trade name of POREFLON. Porous PTFE filters, one of these porous PTFE products, use s...

Metal incorporation into nanoporous carbon

Nanoporous carbon films were deposited by 248 nm pulsed laser ablation of a graphite target in different background pressures of argon (PAr). The morphology changed from smooth, high-density amorphous carbon films at PAr = 20 mTorr to ultra-low density nanoporous material at PAr = 380 mTorr. Subsequently, the nanostructural, chemical and electrical properties of metal containing nanoporous carb...

UV patterned nanoporous solid-liquid core waveguides.

Nanoporous Solid-Liquid core waveguides were prepared by UV induced surface modification of hydrophobic nanoporous polymers. With this method, the index contrast (deltan = 0.20) is a result of selective water infiltration. The waveguide core is defined by UV light, rendering the exposed part of a nanoporous polymer block hydrophilic. A propagation loss of 0.62 dB/mm and a bend loss of 0.81 dB/9...

Hierarchically ordered CdS doped nanoporous membrane.

Large-dimension heterogeneous nanoporous membranes were obtained by the formation of CdS doped mesoporous silica within the porous channels of alumina membranes.
