High Resolution Electron Energy Loss Spectroscopy
High resolution electron energy loss spectroscopy (HREELS) is a tool used in surface science. The inelastic scattering of electrons from surfaces is utilized to study electronic excitations or vibrational modes of the surface or of molecules adsorbed to a surface. Hence in contrast to other electron energy loss spectroscopies (EELS) HREELS deals with small energy losses in the range of 10−3 eV to 1 eV. It plays an important role in the investigation of surface structure, catalysis, dispersion of surface phonons and the monitoring of epitaxial growth.

Famous quotes containing the words high, resolution, energy and/or loss:
“Like an unseasonable stormy day,
Which makes the silver rivers drown their shores,
As if the world were all dissolved to tears,
So high above his limits swells the rage
Of Bolingbroke.”
—William Shakespeare (15641616)
“I had crossed de line of which I had so long been dreaming. I was free; but dere was no one to welcome me to de land of freedom. I was a stranger in a strange land, and my home after all was down in de old cabin quarter, wid de ole folks, and my brudders and sisters. But to dis solemn resolution I came; I was free, and dey should be free also; I would make a home for dem in de North, and de Lord helping me, I would bring dem all dere.”
—Harriet Tubman (c. 18201913)
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called self-interestedness. This was not a portrait of man warts and all. It was all wart.”
—George F. Will (b. 1941)
“Every farewell combines loss and new freedom.”
—Mason Cooley (b. 1927)
