Synthesis and characterization of Gd2O2 S: Tb3+ phosphor powder for X-ray imaging detectors
Gadolinium oxysulfide phosphor doped with trivalent terbium have been synthesized using urea homogenous precipitation and followed by sulfurization at 800 °C under argon atmosphere. Structural and morphological of synthesized phosphor powder were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). Hexagonal structure ...
متن کاملPowder Methods
In one form of powder methods, the powder is compressed in a die and subsequently sintered. The final dimensions are determined by the powder, die, compaction pressure, and sintering densification cycle. The higher the compaction pressure, the higher the final density and properties. Minimal densification occurs in sintering if the powders are large and the sintering temperature is low. This is...
متن کاملBaking Powder
A mixture of powdered compounds added to dough or cake mixture to make it rise in cooking. It is used as a substitute for yeast in bread-making. Baking powders consist of a source of carbon dioxide, such as sodium hydrogencarbonate or ammonium hydrogencarbonate, and an acidic substance such as calcium hydrogenphosphate, potassium hydrogentartrate (cream of tartar), or sodium hydrogenphosphate. ...
متن کاملPharmacokinetics and Bioequivalence of Doxycycline (Providox and Doxyvet 0-50 S ) Oral Powder Formulations in Chickens
A bioequivalence and pharmacokinetics profiles of two doxycycline powder formulations (Providox and Doxyvet 0-50 S ) were compared in 24 healthy chickens following administration of a single oral dose ® (20 mg/kg bw). Serial blood samples were drawn at 10 points after administration to determine doxycycline concentrations in chicken plasma by HPLC/UV. the pharmacokinetics parameters; area under...
متن کاملSynthesis, structural and morphological characterization of CeO2 – ZnO nanosized powder systems from Pechini ́s method
This work reports on the investigation of nanosized CeO2-ZnO systems prepared by Pechini ́s method. The structural and morphological characterization of CeO2-ZnO systems as well as the characterization of CeO2 and ZnO separately, showed that the employed method result in powders with spheroidal particles whose size are in the range 30 200 nm, which is appropriate to provide homogeneous suspensio...
