Optical Resolution by Polymeric Membranes.

Functionalized Polymeric Membranes for CO2 Capture

Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

Effect of amine structure on CO2 capture by polymeric membranes

Poly(amidoamine)s (PAMAMs) incorporated into a cross-linked poly(ethylene glycol) exhibited excellent CO2 separation properties over H2. However, the CO2 permeability should be increased for practical applications. Monoethanolamine (MEA) used as a CO2 determining agent in the current CO2 capture technology at demonstration scale was readily immobilized in poly(vinyl alcohol) (PVA) matrix by sol...

Capped Optical Polymeric Waveguide

We present here a new type of polymer waveguides (i.e., capped waveguide) fabricated using contact photolithography with considerable performance improvement over the conventional waveguides. We also show that by simultaneous patterning of the core and the top cladding in capped waveguides, we can considerably reduce the effect of fabrication defects and reduce the propagation lose by at least ...
