Give the symbol for each element: (a) sulfur, (b) sodium, and (c) aluminum. What is the particle diagram for the thermite reaction? Differentiate between polar and nonpolar molecules. Write down the equilibrium condition for the following reaction: 2H left right arrow H2 W...
a Schematic diagram of the experimental setup. Electrical excitation (voltage source) and optical excitation (450 nm pulsed laser) are simultaneously applied on the single QD. Intensities and time-correlated single-photon-counting data are recorded simultaneously, enabling probe of states relevant to...
