The fabrication of electrically conductive hydrogels is challenging as the introduction an filler often changes mechanical hydrogel matrix properties. Here, we present approach for preparation composites with outstanding electrical conductivity at extremely low loadings (0.34 S m–1, 0.16 vol %). Exfoliated graphene and polyacrylamide are microengineered to 3D such that pathways pervade similar ...

Abstract Based on the combined use of polymerisable polyacrylamide, collagen and an aqueous solution Flavin adenine dinucleotide (FAD), we have developed a new technique for fabrication composite phantoms mimicking fluorescence properties human skin. A comparative analysis absorption scattering coefficients, refractive indices, as well spectra with different concentrations FAD measured CCD spec...

The importance of various factors relating to the preparation of polyacrylamide flocculant solutions was investigated. For optimum results, these solutions should be agitated for at least 2 hours before use while water of high ionic content should be avoided. The quantity of calcium phosphate precipitated during the clarification reaction and the calcium concentration in clear juice are shown t...

Abstract Polymer flooding is an Enhanced oil recovery (EOR) method using chemicals, such as xanthan gum and polyacrylamide which are widely used in the field. can improve mobility of injection fluid, but reservoir polymer has interaction with sand known adsorption causes some to be bound surface pore sand, so that it impact on ineffectiveness injection. The purpose this study want determine com...

BACKGROUND Polyacrylamide gels, containing a hydrogel composed of polyacrylamide and water, are used for soft tissue augmentation and contour correction. There are no reports of significant complications after injection of this material into the face. OBJECTIVE We report an inflammatory reaction after injection of polyacrylamide gels for zygomatic facial augmentation. METHODS A retrospectiv...
