"The only way to know if a reaction has occurred or not is to perform extensive analysis after a multi-step purification.". "When the reactions occurs, the nanoparticle fluoresces at a different color, allowing us to gauge kinetics by eye, instead of with a million-dollar spectrometer," Maye says. At the nanoscale, perovskites are photo-luminescent, meaning that they emit light when "excited" by a laser or lamp. The associated p value is given by the color scale: the more the color tends toward red, the more statistically significant the difference. The color of the indicator may not return to the exact same shade of blue as the control. The tree secures the cut until the leaf is lastly blown off and also leaves a fallen leave scar on the tree.

Chemical reactions often produce spectacular color changes that appear to happen just by magic. As the halide is released, or exchanged in the chemical reaction, our particle absorbs it, and the fluorescence color changes proportionally to the halide concentrationfrom red to orange to yellow to green. Depending on whether it's a boy or a girl (doctors note is sealed in an envelope), a friend will pass us a bunch of non descript chemicals to mix together and the resulting color is either pink or blue.
