Fire-retardant solid polymer electrolyte films prepared from oxetane derivative with dimethyl phosphate ester group

Submicron Films Prepared from Aqueous Dispersions of Nanoscale Polymer Crystals

Thin and ultrathin films of polyethylene of variable thickness are obtained from aqueous dispersions of prefabricated nanoscale crystals by spin-coating. Continuous films with a thickness of only 15 nm, up to 220 rim, homogeneous over hundreds of pm, or assembled discontinuous monolayers of flat-on lamella particles were prepared, depending on the solids content of the dispersion employed, as r...

Nanostructured Layered Copper Hydroxy Dodecyl Sulfate: A Potential Fire Retardant for Poly(vinyl Ester) (PVE)

The reaction of hydrogen peroxide with the dimethyl ester heme derivative of cytochrome c peroxidase.

A modified cytochrome c peroxidase was prepared by reconstituting apocytochrome c peroxidase with protoheme in which both heme propionic acid groups were converted to the methyl ester derivatives. The modified enzyme reacted with hydrogen peroxide with a rate constant of (1.3 +/- 0.2) x 10(7) M-1 s-1, which is 28% that of the native enzyme. The reaction between the modified enzyme and hydrogen ...

Solid polymer electrolyte membranes for fuel cell applications—a review

Fuel cells represent a clean alternative to current technologies for utilizing hydrocarbon fuel resources. Polymer electrolyte membrane fuel cells (PEMFCs) have acquired due importance as they are best suited for applications where a quick start up is required such as in automobiles. The prime requirements of fuel cell membranes are high proton conductivity, low methanol/water permeability, goo...
