A sensitive and reliable method was developed for the determination of tetracaine and its metabolite, p-butylaminobenzoic acid, in human samples. Tetracaine and the metabolite, effectively extracted using a liquid-liquid extraction procedure from 0.5 g of sample, were analyzed by gas

To investigate the reinforcement of Bis-GMA/TEGDMA dental resins (without conventional glass filler) and composites (with conventional glass filler) with various mass fractions of nano fibrillar silicate (FS). Three dispersion methods were studied to separate the silanized FS as nano-scaled single

The purpose of this study was to evaluate the effects of photoinitiator type and water content on the polymerization rate (Rp) and degree of conversion (DC) of a model BisGMA/HEMA-based resin. The comonomer mixture consisted of BisGMA/HEMA (60/40 by weight).
The imidazole of chromophoric p-(dimethylamino)benzoic acid, DABIm, reacts with the serine protease alpha-chymotrypsin in the pH range of 4-7 to form a stable acyl intermediate that gives very good resonance-enhanced Raman spectra. The resonance Raman and absorption spectra of the
