Formation and characterization of inorganic membranes from zeolite-silica microcomposites [PDF]
, 1988 Small crystals of zeolites (500-1000 nm) with two- and three-dimensional channel systems (faujasite and ZSM-5 structures) were embedded in amorphous thin films derived from TEOS hydrolyzed in alcoholic solution.

Performance of a 1 kW Class Nafion-PTFE Composite Membrane Fuel Cell Stack
International Journal of Chemical Engineering, 2012 Composite membranes have been prepared by impregnation of Nafion into the expanded polytetrafluoroethylene (EPTFE) matrix. Nafion loading in the composite membranes was kept constant at 2 mg/cm2.

Fluctuation spectrum of fluid membranes coupled to an elastic meshwork: jump of the effective surface tension at the mesh size [PDF]
, 2003 We identify a class of composite membranes: fluid bilayers coupled to an elastic meshwork, that are such that the meshwork's energy is a function $F_\mathrm{el}[A_\xi]$ \textit{not} of the real microscopic membrane area $A$, but of a \textit{smoothed ...

A rationale for the preparation of asymmetric pervaporation membranes [PDF]
, 1985 Pervaporation is carried out primarily with homogeneous membranes. An improvement in permeation rate can be achieved by using asymmetric or composite membranes. In order to maintain a high selectivity, very dense top layers are needed.

Protein composition of the glyoxysomal membrane [PDF]
FEBS Letters, 1974 Membranes of glyoxysomes, a special form of peroxisomes, have been recently isolated and characterized to some extent [l-3] . Knowledge of the protein composition of these membranes should be of interest, since, up to now, mainly because of the lack of availability of suitable preparations, the protein pattern of wed-de~ned fractions of isolated ...

Synthesis of silicalite-poly(furfuryl alcohol) composite membranes for oxygen enrichment from air [PDF]
, 2011 Silicalite-poly(furfuryl alcohol) [PFA] composite membranes were prepared by solution casting of silicalite-furfuryl alcohol [FA] suspension on a porous polysulfone substrate and subsequent in situ polymerization of FA.
