Oxygen diffusivities in mullite/zirconia composites were measured by 18O/16O isotope exchange and secondary ion mass spectrometry. They exhibited a wide range of values from 10−21 to 10−10 m2/s at temperatures between 1000 and 1350 °C in the composites with 0 to 80 vol% zirconia. At a fixed temperature, oxygen diffusivities in high-zirconia composites were larger by at least eight orders of magnitude than those in low-zirconia composites. The percolation threshold occurred between 30 and 40 vol% zirconia, where oxygen diffusivities dramatically changed. There was a clear tendency of the activation energies of oxygen diffusion in composites to decrease with increasing zirconia contents. The large oxygen diffusivities in the high-zirconia composites were attributed to the interconnected channels of zirconia from the microstructural aspect.

The analysis of the surface chemistry of organic materials or of organic molecules at surfaces presents special problems. Firstly there is the requirement of high chemical specificity and the ability to detect small differences in chemical state. Secondly, organics are very sensitive to damage by the radiation used for the analysis. Over recent years, static secondary ion mass spectrometry (SSIMS) has been developed into a technique which is able to provide the power of mass spectrometry for the chemical characterization of surfaces. Furthermore, the advent of time-of-flight mass spectrometry techniques has enabled very high sensitivity with little sample damage. The power of the technique is illustrated by its application to four areas of surface investigation: the adsorption and reaction of propene at a ruthenium single crystal surface; the interaction of organic lubricants at a synthetic ‘gold’ surface; the interaction of bioactive molecules at a model cell membrane surface, and the identification of contamination responsible for adhesive failure.

Abstract Paintings often consist of highly complex layered structures that contain a mixture of organic and inorganic materials at each layer depending upon the artist’s technique. A comprehensive analysis of the chemical composition could provide critical information on the sequence of events that led to an artwork’s current state. In this investigation, we have employed a novel imaging technique known as Secondary Ion Mass Spectrometry (SIMS) to chemically map the cross-section of a paint film sampled from Leonardo da Vinci’s Adoration of the Magi at a submicron resolution using a C60+ ion source. A wide range of materials were found to be spatially localized at the different layers such as: protein, carbon, silicates, fatty acids, salts and lead associated compounds. An interaction of chloride salts with the lead white was observed in the priming layer. The chloride salts disrupted most of the priming layer suggesting that a cleaning process took place that removed most of the priming layer before the monochrome brown repaints were added on top at a later time.
