The results are analyzed in terms of excitonic excitation, charge separation, and transport between the core and the shell, which is useful for photovoltaic applications.Ĭ.K. Mechanical Engineering Seminar Series, KFUPM, Dhahran, Saudi Arabia. Upon on-off cycles of UV irradiation and visible light, the red core switches reversibly between bright and dark states while PANI switches reversibly between emeraldine green and pernigraniline violet states. Head of Department of Mathematics, Statistics and Physics, College of Arts and. Physics 101 kfupm manuals#We also monitor the optical properties of the Si core and the PANI shell using fluorescence microscopy under UV and visible irradiation.

We use high resolution transmission electron microscopy (HTEM) and scanning electron microscopy (SEM) to record the structural properties. Thin films of the capsules were formed on a variety of substrates. The capsules are produced by miniemulsion of aniline monomers in the presence of Si nanoparticles. Physics 101 kfupm manual#The Si particles absorb UV/blue efficiently and green moderately, while polyaniline (PANI) in its green emeraldine state absorbs UV and red/IR efficiently, effectively providing absorption over a wide range of the solar spectrum. PHYS 101 Lab Manual 2007 Edition Department of Physics King Fahd University of Petroleum & Minerals Chairman 31261 Saudi Arabia King Fahd University of. 243 Saudi Center for Theoretical Physics, King Fahd University of Petroleum and Minerals (KFUPM). His research interests are enhanced oil recovery, fluid mechanics, and soft condensed matter physics. He is an experimentalist who specialized in fluid mechanics and optics. Teaching experience at the undergraduate and graduate levels includes classical mechanics, electromagnetics, solid state physics, mathematical physics, and quantum mechanics. We examine the optical and structural properties of polyaniline–silicon nanoparticle capsules - a novel organic/inorganic material. Before joining KFUPM, he was a research associate in the Department of Physics at The Chinese University of Hong Kong. ![]()
