Journal ArticleDOI

Markus Mezger,Heiko Schröder,Harald Reichert,S. M. Schramm,John Okasinski,S. Schöder,S. Schöder,Veijo Honkimäki,Moshe Deutsch,Benjamin M. Ocko,John Ralston,Michael Rohwerder,Martin Stratmann,Helmut Dosch,Helmut Dosch +14 more
TL;DR: Room-temperature ionic liquids with the tris(pentafluoroethyl)trifluorophosphate anion in contact with a charged sapphire substrate were investigated with submolecular resolution and showed strong interfacial layering, akin to the charge inversion effect.
Journal ArticleDOI
Capillary Waves on the Surface of Simple Liquids Measured by X-Ray Reflectivity
A. Braslau,Peter S. Pershan,G. Swislow,Benjamin M. Ocko,Benjamin M. Ocko,Jens Aage Als-Nielsen +5 more
TL;DR: The properties of the liquid-vapor interface for three simple liquids have been measured using x-ray reflectivity and the measured surface roughness is interpreted using a model that combines the effects of thermally induced capillary waves and the dimensions of the constituent molecules.
Journal ArticleDOI
X-Ray Specular Reflection Studies of Silicon Coated by Organic Monolayers (Alkylsiloxanes)
I. M. Tidswell,Benjamin M. Ocko,Peter S. Pershan,Stephen R. Wasserman,George M. Whitesides,J. D. Axe +5 more
TL;DR: The ability to use x-ray reflectivity to characterize chemical changes before and after chemical reaction of a monolayer in which the alkyl chain was terminated by an olefinic group was demonstrated.
Journal ArticleDOI
Surface freezing in chain molecules: Normal alkanes
TL;DR: In this paper, a rare surface freezing phenomenon is observed in normal alkanes, using x-ray and surface tension measurements, and an ordered monolayer forms on the surface of the liquid alkane at temperatures up to 3 \ifmmode^\circ\else\textdegree\fi{}C above the bulk freezing temperature.
Journal ArticleDOI
X-ray reflectivity measurements of surface layering in liquid mercury.
TL;DR: The surface normal structure of the mercury liquid-vapor interface has been investigated by measuring the x-ray reflectivity out to a momentum transfer of {ital q}{sub {ital z}}=2.5 A, providing direct experimental proof of surface layering in liquid metals.
