Stability of the passivation quality poly-Si on oxide junctions against conventional mainstream high-temperature screen-print firing processes is highly desirable and also expected since preparation occurs at higher temperatures for longer durations than firing. We measure recombination current densities (J0) interface state (Dit) symmetrical samples with n-type contacts before after Samples wi...

Co-firing ramie residue with coal was carried out in a thermogravimetric analyzer and a cyclone furnace to evaluate the effects of coal fraction (0 to 30 wt. %) on combustion performance. Thermogravimetric analysis (TGA) results showed that devolatilisation was the predominant process when the coal percentage in the blend was below 30 wt. %. For pure biomass firing in the cyclone furnace, an op...

Changes in temperature of up to several degrees have been reported in different brain regions during various behaviors or in response to environmental stimuli. We investigated temperature sensitivity of dopaminergic neurons of the rat substantia nigra pars compacta (SNc), an area important for motor and emotional control, using a combination of electrophysiological techniques, microfluorometry,...

The composition and properties of two types calcined magnesium oxide powders, differing in chemical composition, are investigated. difference phase determines the different behavior powders during firing, which is smoothed only at a temperature more than 1850 °C. microstructure obtained briquettes differs amount glass phase, type size pores, as well quality crystals periclase. From studied deca...
