We have designed and synthesized a new thiocyanate-free sensitizer coded as SPS-01 and used it as the sensitizer in a TiO(2) based nanocrystalline dye-sensitized solar cell (DSSC). SPS-01 exhibits strong visible absorption properties with maximum peak around at 532 nm. The overall power conversion efficiency (PCE) of a DSSC sensitized with SPS-01 (7.96%) is higher than that of N719 (7.30%) unde...

Sir, Recalcitrant warts remains a major therapeutic challenge for patients as well as for dermatologists, and an effective, painless, atraumatic treatment modality is needed world-wide. Topical immunotherapy has for years been used with some success in the treatment of resistant warts (1). Dinitrochlorobenzene (DNCB) was the ®rst contact sensitizer to be used but diphenylcyclopropenone (DCP) is...

An Osmium sensitizer and anthracene annihilator are incorporated into a metal ion linked multilayer photoanode that harnesses NIR light in an integrated triplet–triplet annihilation upconversion solar cell.

A mass spectrometry compatible silver staining method for protein incorporating a new silver sensitizer in sodium dodecyl sulfate-polyacrylamide electrophoresis gels

In this work, a new organic compound (K-Azo) was introduced to enhance the electrical and optical performance of graphene oxide (GO) reduced GO (rGO) nanostructured films. The improved modified chemical vapour method employed for synthesis rGO. photophysical characterization thin films performed by applying analytical techniques including X-ray diffraction, Fourier-transform infrared spectrosco...

The elimination of malignancy is the ultimate oncologic goal. Many tumors can be killed by large amounts of chemotherapy or ionizing radiation. Unfortunately, host tolerance to treatment frequently limits the extent to which these modalities can be used. Therefore, skilled use of effective but nonselective modalities is the present basis of oncology. The recent clinical interest in the use of p...

The kinetics of the sensitized photodegradation of a variety of well-defined lignin model compounds was studied to determine the mechanisms responsible for lignin's photochemically-mediated oxidation. Monomeric and dimeric models representing lignin's phenolic end groups and nonphenolic dimers representing its inner core were studied. It was determined that the rate constants for the reaction o...
