The Effect of Turbulence on Rates of Particle Formation by Homogeneous Nucleation
The effect of turbulent mixing on the homogeneous nucleation rate was studied for a jet stream at 400 K injected into dry air at 298 K and 1 atm. To simplify the calculations, it was assumed that theExpand

Production of rounded Ti- and Al-hydroxide particles in a turbulent jet by coagulation-controlled growth followed by rapid coalescence
Experiments were made to form titanium and aluminum hydroxide particles in lab scale turbulent subsonic gas jets with nozzle diameters of 0.2 to 0.4 cm. Small clusters formed by homogeneousExpand

Narrow Red Emission Band Fluoride Phosphor KNaSiF6:Mn(4+) for Warm White Light-Emitting Diodes.
Red phosphors AMF6:Mn(4+) (A = Na, K, Cs, Ba, Rb; M = Si, Ti, Ge) have been widely studied due to the narrow red emission bands around 630 nm. The different emission of the zero-phonon line (ZPL) mayExpand

Temperature effect on the emission spectra of narrow band Mn4+ phosphors for application in LEDs.
Temperature dependence of the luminescence shape and decay time of narrow band Mn4+ fluoride phosphors: Rb2GeF6:Mn4+ and KNaSiF6:Mn4+ was investigated. The temperature changes in the relativeExpand
