Role of Rose Bengal-Mannitol system for generation of electrical energy in photogalvanic cell
نویسندگان
چکیده
Photogalvanic effect was studied in photogalvanic cells containing Rose Bengal as dyes and Mannitol as reductants. The photogalvanic cells were determined by the photo potential, photocurrent, conversion efficiency, power of cell and performance of cell. The effects of various parameters like pH, light intensity, diffusion length, reductant concentration and dye concentration on the electrical output of the cell is studied. The current voltage (i-V) characteristic of the cell is also studied and a mechanism for the generation of photocurrent is proposed.

Role of Caspases and Reactive Oxygen Species in Rose Bengal-Induced Toxicity in Melanoma Cells
Objective We have previously shown that Rose Bengal (RB) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. To clarify RB-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ROS) were studied in melanoma cells. Material and Methods Human melanoma cell lines, Me 4405 and Sk-Mel-28 were cultured in DM...
متن کاملA Comparative Study of Photocatalytic Activity of Some Coloured Semiconducting Oxides
The use of colored semiconductor oxide like copper (II) oxide and nickel (II) oxide for photocatalytic bleaching of rose bengal was investigated in detail. In order to harness the solar energy, the effective wavelength of the photocatalyst is to be expanded into the visible region and that increases the rate of photocatalytic bleaching of the dye. Progress of the reaction was observed spect...
