8 Quality Samples = Quality Science Must have the tools.

9 Quality Science Data Speaks for Itself Signal to Imagination Ratio >> 1 New Information Revealed Physical Insight Reproducible Results You Gotta Make it Stick Sufficiently Advanced Not a New Formulation of an Old Problem

10 History of yours truly, of course.

11 CO Chemisorption Effect on Magnetic Properties The magnetization is reduced by the adsorption of CO. The slope of the magnetization curve changes upon heating above the desorption temperature for CO. CO chemisorption also modifies the magnetic anisotropy. 93 Surface Science Letters

12 H 2 Chemisorption Effects on Magnetic Properties The in-plane magnetization of Co films decreases with H-adsorption. The perpendicular magnetization of Fe films increases with H-adsorption. Co Fe Fe 93 JVST R. Vollmer and J. Kirshner, 00 PRB.
