Highly-stretchable self-standing curdlan (1,3-?-d-glucan) hydrogels were prepared via chemical cross-linking using various cross-linkers, including ethylene glycol diglycidyl ether, 1,4-butandiol and 1,6-hexanediol ether. Tensile testing of the revealed that had good elongation properties with 600%–900% strain from their original length regardless cross-linker length. Stretched-dried-gel films ...

The construction of molecular models of crosslinked polymers is an area of some difficulty and considerable interest. We report here a new method of constructing these models and validate the method by modelling three epoxy systems based on the epoxy monomers bisphenol F diglycidyl ether (BFDGE) and triglycidyl-p-amino phenol (TGAP) with the curing agent diamino diphenyl sulphone (DDS). The mai...

Synthetic polyammonium/polyamine receptors are known to enhance ATP dephosphorylation in solution. ATP interaction with a G-3 poly(ethylene imine) dendrimer shows an unprecedented behaviour, the dendrimer catalyst being able to enhance or inhibit dephosphorylation of the nucleotide depending on the solution pH.

Epoxy resins find widespread use as adhesives and coatings in the construction and food industries. The majority of the products are based on resins that use bisphenol A diglycidyl ether (BADGE) as a precursor. This raises the question if BADGE could be a potential source of bisphenol A (BPA). The recent paper by Perez et al. (1) on the estrogenicity of BPA and some of its analogs and derivativ...
