The purpose of this study was to evaluate the surface and intrapulpal temperatures after treatments with different bleaching gels subjected to different types of light activation. A K-type thermocouple and infrared thermometer were used to measure the temperature increase during the 15- or 30-min treatment period. Light-emitting diode with a center wavelength of 405 nm (LED405), organic light-emitting...
•Comparison of high-resolution absorption spectra of Rb, Cs and RbCs vapor mixture.•Satellite bands of RbCs molecule at 362.2nm, 372.5nm and 390.7nm.•Avoided crossings of potential curves at long-range inter-atomic region.•The observed satellite bands may be observed in the mixed Rb–Cs MOT.•The satellite bands can be used for comparison with ab initio RbCs calculations.
Nanostructured polymer electrolytes are very attractive materials for components of batteries and opto-electronic devices. (PEO) 8 ZnCl 2 polymer electrolytes and nanocomposites were prepared using Poly(ethylene oxide) (PEO) γ-irradiated with a selected dose of 529 kGy and with an addition of 10% of TiO 2 nanograins. The influence of the added nanosize TiO 2 grains...
We compared the visible and the infrared spectrum of cesium and the sodium high pressure discharge light sources of 70W power, run at different voltages from 180 to 240V. Although the cesium discharge lamp exhibits remarkable white light in the visible spectrum, it suffers from the large infrared radiation intensity. The study of the causes of large infrared losses and their possible reduction was...
