Low Toxic

In this paper the two new low toxic water-soluble monomers: glycerol monoacrylate and 3-O-acrylic-D-glucose are introduced and their application in gelcasting of alumina powder is reported, in comparison with 2-hydroxyethyl acrylate, the commercial monomer. Both synthesized substances do not need an addition of cross-linking agent to the ceramic slurry, because hydrogen bonds can be formed in the polymer network, owing to the presence of two or more hydroxyl groups in their molecules, unlike in the case of 2-hydroxyethyl acrylate. Rheological behavior of alumina gelcasting suspensions containing these monomers has been studied, as well as the characteristics of raw and sintered elements formed from these slurries by initializing an in situ polymerization.

Graphene-based membranes are promising candidates for efficient organic solvent nanofiltration (OSN) processes because of their unique structural characteristics, such as mechanical/chemical stability and precise molecular sieving. Recently, to improve organic solvent permeance and selectivity, nanopores have been fabricated on graphene planes via chemical and physical methods. The nanopores serve as an additional channel for facilitating ultrafast solvent permeation while filtering organic molecules by size exclusion. This review summarizes the recent developments in nanoporous graphene (NG)-based membranes for OSN applications. The membranes are categorized depending on the membrane structure: single-layer NG, multilayer NG, and graphene-based composite membranes hybridized with other porous materials. Techniques for nanopore generation on graphene, as well as the challenges faced and the perspectives required for the commercialization of NG membranes, are also discussed.
