Cost-Effective Free Fall Apparatus

Cost-Effective Free Fall Apparatus for Elementary and Secondary Students. Public Schools do not have sufficient funds for the purchase of a Free-Fall Apparatus, which is used to measure the time for a falling object to…

Para-Toluenesulfonate Doped Polypyrolle as EMF Electrode Source

A conducting polymer was synthesized from polypyrolle doped with paratoluenesulfonate (p-TS) using electrochemical deposition technique to find a substitute for metal electrodes in EMF sources. Samples were produced with varying p-TS molarity, specifically 0.1, 0.15,…

Elastomeric Grating for Wavelength Switching

Elastomeric Grating for Wavelength Switching in Optical Communication Systems. A diffraction grating was fabricated from an elastic polymer. It was patterned after a plane reflection grating with a pitch of 1,200 lines/mm. It was characterized…
