SPECTROFLUORIMETRIC METHOD FOR DETERMINATION OF SOME OXICAMS USING POTASSIUM BROMATE [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 2008 A sensitive and selective spectrofluorimetric method has beendeveloped for the determination of some non-steroidal antiinflammatoryoxicams derivatives namely: tenoxicam (Tx),piroxicam (Px) and lornoxicam (Lx) after their complete oxidativeacidic ...

Chemistry – A European Journal, EarlyView.Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Chemistry – A European Journal, EarlyView.We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Chemistry – A European Journal, EarlyView.This study investigates how molecular topology influences the photophysical properties of star‐shaped, threefold‐symmetric triphenylamine (TPA) derivatives functionalized with three BODIPY or SubPc units. Their absorption spectra exhibit minimal solvatochromism, whereas their fluorescence intensity is strongly dependent on solvent polarity.

Mechanisms of Potassium Bromate Induced Thyroid Carcinogenesis [PDF]
, 2001 Bromate (BrO3-) occurs in finished drinking water as a by-product of the ozonation disinfection process. Potassium bromate, the experimental model compound, has been found to induce thyroid follicular cell tumors in the rat after 100 weeks.
