Pattern formation during polymerization of acrylamide in the presence of sulfide ions

Article Abstract:

Research was conducted to examine pattern formation during polymerization of acrylamide in the presence of sulfide ions. The preparation of the thin gel layer was done using a mixture of acrylamide, N,N'-methylene-bisacrylamide and triethanolamine with a peroxodisulfate initiator in the presence of sulfide. When water was spread over the gel after solidifying, spatial pattern formation was observed in the gel. Results reveal that sulfide ion terminates the polymer chain elongation while retaining the overall exothermic chain reaction.

New platform for testing candidate materials for organic field-effect transistors

Article Abstract:

A field effect transistor platform was designed and fabricated from silicon that allows for the testing of organic semiconductors (OS) as potential materials for organic field-effect transistors (OFET) and as the gate conductor was chemically sensitive field-effect transistors (CHEMFET). No semiconductor field-effect was observed in OFET mode using poly (phenylene sulfidephenyleneamine) as the organic semiconductor.
