Antihistaminics as epinephrine sensitizer

Antihistaminics, local anesthetics, and other amines as antiviral agents.

A number of lipophilic amines of diverse chemical structure, including antihistaminics, local anesthetics, and chloroquine, were found to exhibit similar kinetics in inhibiting the infection of BHK cells by vesicular stomatitis virus. The inhibition occurred prior to both primary and secondary RNA transcription but following transfer from the cell surface to an intracellular site, presumed to b...

CoAPO5 as a water oxidation catalyst and a light sensitizer.

We report the first use of cobalt aluminophosphate (CoAPO5) as a water oxidation catalyst. A decrease in the overvoltage by about 0.2 V with respect to catalyst free FTO has been observed. Additionally, we show that CoAPO5, deposited on ITO or Pt, can also act as a photo-electro-catalyst, as it generates enhanced oxidation currents in the presence of light starting from a bias of +0.8 V vs. Ag/...

Near-IR phosphorescent metalloporphyrin as a photochemical upconversion sensitizer.

The phosphorescent metalloporphyrin sensitizer PtTPTNP (TPTNP = tetraphenyltetranaphtho[2,3]porphyrin) has been successfully coupled with perylenediimide (PDI) or rubrene utilized as triplet acceptors/annihilators to upconvert 690 nm incident photons into yellow fluorescence through sensitized triplet-triplet annihilation at overall efficiencies in the 6-7% range while exhibiting exceptional ph...

Application of azo dye as sensitizer in dye-sensitized solar cells

An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...
