THE GELATION FROM SILK FIBROIN AQUEOUS SOLUTION IN PRESENCE OF COPPER (II) ION

Sodium dodecyl sulfate-induced rapid gelation of silk fibroin.

The in situ formation of injectable silk fibroin (SF) hydrogels have potential advantages over various other biomaterials due to the minimal invasiveness during application. Biomaterials need to gel rapidly under physiological conditions after injection. In the current paper, a novel way to accelerate SF gelation using an anionic surfactant, sodium dodecyl sulfate (SDS), as a gelling agent is r...

Elimination of Copper (II) Ions from Aqueous Solution by the using of gamma alumina nanoparticles

heavy metals, as gamma alumina nanoparticles pollutants, in water resources. Therefore, the purpose of this paper was to evaluate the removal of copper (II) ions from aqueous solutions using gamma alumina nanoparticles as a adsorbent. Batch adsorption studies carried out to study various parameters included contact time, initial concentration of copper (II) ions, pH, and gamma alumina nanoparti...

Silk fibroin gelation via non-solvent induced phase separation.

Tissue engineering benefits from novel materials with precisely tunable physical, chemical and mechanical properties over a broad range. Here we report a practical approach to prepare Bombyx mori silk fibroin hydrogels using the principle of non-solvent induced phase separation (NIPS). A combination of reconstituted silk fibroin (RSF) and methanol (non-solvent), with a final concentration of 2....

Removal of Copper from Aqueous Solution by Ion Exchange Resins

Adsorption of Copper (II) Ions from Aqueous Solution onto Activated Carbon Prepared from Cane Papyrus

The present study evaluates the suitability ofactivated carbon, prepared from Cane Papyrus, a plant that grows naturally and can be found quite easily, which serves as a biological sorbent for removal of  Cu2+ ions from aqueous solutions. Fourier transform infra-red analysis for the activated carbon, prepared fromCane Papyrus confirms the presence of amino (–NH), carbonyl (–C=O), and hydroxyl (...
