the muscle-like technology would be of enormous advantages for biomedical applications such as medical implants and human assist devices. ionic polymer metal composites (ipmcs) are one kind of biomimetic actuators. an ionic polymer metal composite composed from an ionomer with high ion exchange capacity that packed between two thin metal layers. in the present study we focused on the preparatio...

Acharan sulfate is a glycosaminoglycan prepared from the giant African snail, Achatina fulica. This polysaccharide has a repeating disaccharide structure of -->4)-2-deoxy-2-acetamido-alpha-D-glucopyranose (1-->4)-2-sulfo-alpha-L-idopyranosyluronic acid (1-->). Its structure is related to heparin and heparan sulfate but is distinctly different from all known members of these classes of glycosami...

Cyclic tetrapyrroles are among the most potent compounds with activity against transmissible spongiform encephalopathies (TSEs; or prion diseases). Here the effects of differential sulfonation and metal binding to cyclic tetrapyrroles were investigated. Their potencies in inhibiting disease-associated protease-resistant prion protein were compared in several types of TSE-infected cell cultures....

The use of surfactants from palm oil as a wetting agent can be applied in the textile wet processes. Used cooking that has been through esterification and transesterification processes used raw material for surfactants. During this process, methyl ester sulfonate formed surfactant material. MES an active ingredient detergents detergency ability water with high hardness level, tolerance property...

A simple method is reported for the preparation of self-assembling sulfonated graphene oxide membranes (SGO-X) to be studied as a potential proton conductor exchange membrane fuel cells (PEMFCs). The effect three different sulfuric acid-to-GO molar ratios investigated, main aim being identification an optimal sulfonation interval ensuring successful trade-off among composition, structural stabi...
