ABSTRACTWe present results of a study motivated by the recent suggestion that the properties of nanocrystalline materials with a large surface-to-volume ratio can be tuned by inducing spacecharge regions at interfaces by means of an applied voltage. As an example, we investigate the reversible variation of the lattice constant of platinum nanoparticles immersed in an aqueous 1M KOH electrolyte as a function of applied potential. It is found that a reversible volumetric strain of up to 1.2 % can be induced, corresponding to pressures of up to 3.2 GPa. We present the experimental set-ups for in-situ X-ray diffraction with an electrochemical cell. The variation of the space charge at the metal-electrolyte interface results in a variation of the surface stress f as a function of the applied potential, which is not an electrocapillary effect.

We describe powder X-ray diffraction experiments on lithium intercalation compounds. Using a unique electrochemical cell which incorporates a beryllium X-ray window we are able to monitor changes in the host lattice which occur when the lithium concentration is altered electrochemically. The detailed design of the cells and experimental problems which arise when using the in situ X-ray diffraction technique are discussed. Results of experiments on LixTiS2 are reported for 0 ≤ x ≤ 2.

Studies of the nature of a surface, either metallic or nonmetallic, in the past, have been limited to the instrumentation available for these measurements. In the past, optical microscopy, replica transmission electron microscopy, electron or X-ray diffraction and optical or X-ray spectroscopy have provided the means of surface characterization. Actually, some of these techniques are not purely surface; the depth of penetration may be a few thousands of an inch. Within the last five years, instrumentation has been made available which now makes it practical for use to study the outer few 100A of layers and characterize it completely from a chemical, physical, and crystallographic standpoint. The scanning electron microscope (SEM) provides a means of viewing the surface of a material in situ to magnifications as high as 250,000X.
