Complex Aerogels Generated from Nano-Polysaccharides and Its Derivatives for Oil–Water Separation

Complex formation between mycobacterial polysaccharides and fatty acyl-CoA derivatives.

The mycobacterial polysaccharides MMP and MGLP, which contain numerous O-methyl-sugar residues, markedly stimulate fatty acid synthesis catalyzed by a multienzyme complex from Mycobacterium phlei [Ilton, M. et al. (1971) Proc. Nat. Acad. Sci. USA 68, 87-91]. When aqueous solutions containing MMP or MGLP and palmitoyl-CoA were chromatographed on Sephadex G-75 under conditions that widely separat...

Microwave Assisted Synthesis of Nano Zeolite Seed for Synthesis Membrane and Investigation of its Permeation Properties for H2 Separation

MFI-type zeolite membranes (ZSM-5) were prepared on α-alumina tubular supports and tested for separation of H2/CO mixtures. The effect of pressure and temperature on H2 and CO flows and selectivity was investigated. The best results in this work were obtained with a ZSM-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with m...

Water-Soluble Single-Nano Carbon Particles: Fullerenol and Its Derivatives

Synthesis and textural characteristics of organic aerogels, transition-metal-containing organic aerogels and their carbonized derivatives

Four organic aerogels were prepared by the sol-gel method from polymerization of resorcinol with formaldehyde catalyzed by Na CO . These aerogels were further pyrolyzed in N in order to obtain their corresponding carbon aerogels, 2 3 2 and after that activated with either steam or CO to obtain activated carbon aerogels. Another series of organic aerogels and 2 their pyrolyzed and activated deri...
