The photostability of dye molecules trapped in transparent solid matrices synthesized by the solgel technique was studied both experimentally and theoretically using a model with numerical and approximate analytical solutions. The model is based on a one-photon photodestruction process with the creation of an absorbing bleached molecule. We give the number of photons that different trapped dye ...

Aim. To compare microleakage of apexification using MTA in one or two sessions. Materials and Methods. 88 single rooted teeth were prepared and divided into two groups then received MTA apical plug. In the first group, the teeth were immersed in normal saline for 24 hours and then backfilled with guttapercha and AH26 sealer. In the second group, the teeth were obturated immediately after receiv...

We have developed a photoelectric dye-coupled polyethylene film as a prototype of retinal prosthesis, named “Okayama University-type retinal prosthesis. The purposes of this study are to conduct behavior tests to assess vision in Royal College of Surgeons (RCS) rats which underwent subretinal implantation of the dye-coupled film, and are also to reveal the retinal response to the dye-coupled fi...

For the first time in dye-sensitized solar cell (DSSC) technology, a di-carbazole-based dye was synthesized and evaluated for its usage as potential sensitizer development of wavelength selective semi-transparent DSSCs greenhouses-oriented applications. The designed to demonstrate blue light absorption, allowing high transmittance red region visible light, even after adsorption on anode semicon...

The conventional iodine-based (I − /I 3 ) electrolyte used in dye-sensitized solar cells (DSSCs) presents several limitations, such as ∼30% absorption of visible light the wavelength range 300–500 nm and a large potential difference between Fermi level I HOMO dye. This has negative impact on characteristics DSSC transparency open circuit voltage (V oc ). In present work, series transparent elec...
