Ionic polymer-metal composites IPMCs consist of a perfluorinated ionomer membrane usually Nafion or Flemion plated on both faces with a noble metal such as gold or platinum and neutralized with the necessary amount of counterions that balance the electrical charge of anions that are covalently fixed to the backbone ionomer. IPMCs are electroactive materials(More)
Ionic polymer-metal composites (IPMCs) consist of a perfluorinated ionomer membrane (usually Nafion or Flemion) plated on both faces with a noble metal such as gold or platinum and neutralized with a certain amount of counterions that balance the electrical charge of anions covalently fixed to the membrane backbone.

This paper reports the application of graphene oxide aerogels (GOAs) for adsorption of lead(II) ions from aqueous solutions. The aerogels were fabricated from graphene oxide (GO) colloidal suspensions by unidirectional freeze drying method. The synthesized GO powders, as well as the aerogels, were thoroughly characterized by various techniques. The(More)
The results of oneand two-dimensional H nuclear magnetic resonance (NMR) pulsed field gradient (PFG) diffusometry studies of water in white cement paste with a water-tocement ratio 0.4 and aged from 1 day to 1 year are reported. The study shows that the NMRPFG method is primarily sensitive to the capillary porosity. Data is fit on the basis of a lognormal(More)
A 5-day-old male Holstein calf was presented with a proliferative mass under the right eye. A solid multilobulated gray lesion (5 cm × 3 cm) was removed surgically. Histopathological findings were characterized by multiple nests of cells, resembled abortive hair follicles. A diagnosis of trichoepithelioma was made. This is considered to be the first report(More)
