Research Reveals How an Acid Dissolves, Molecule by Molecule
Caption: Schematic illustration of the excited state acid dissolution of HBr within the mixed cluster of HBr(H2O)4. The first step in the mechanism is the proton transfer from the acid to a water molecule which is followed by solvent reorganization. © 2002 Castleman Lab, Penn State

Crab Nebula Composite Image A composite image of the Crab Nebula showing the X-ray (blue), and optical (red) images superimposed. The size of the X-ray image is smaller because the higher energy X-ray emitting electrons radiate away their energy more quickly than the lower energy optically emitting electrons as they move.
