This report describes the construction and performance characteristics of a device capable of making rapid serial measurement of rat brain radioactivity following the administration of a positron emitting isotope. Two bismuth germanate oxide (BGO) scintillation detectors in a coincidence detection circuit are used to achieve the necessary degree of collimation. Data from the device can be used ...

Bismuth-germanate glasses, which are well known as a promising active medium for broadband near-infrared spectral range fiber lasers and an initial matrix nonlinear optical glass ceramics, have been synthesized in 5–50 mol% Bi2O3 wide concentration range. Their structural physical characteristics were studied by Raman FT-IR spectroscopy, differential scanning calorimetry, X-ray diffraction, opt...

AIM To report the hydration mechanism of white mineral trioxide aggregate (White MTA, Dentsply, Tulsa Dental Products, Tulsa, OK, USA). METHODOLOGY The chemical constitution of white MTA was studied by viewing the powder in polished sections under the scanning electron microscope (SEM). The hydration of both white MTA and white Portland cement (PC) was studied by characterizing cement hydrate...

A lithium–bismuth–copper co-doped GDC composite (Ce 0.712 Gd 0.178 Li 0.05 Bi Cu 0.01 O 1.801 ) capable of sintering at ∼750 °C with an electrical conductivity 29.6 mS cm −1 was developed for the first time metal-supported solid oxide electrolysers.
