Abstract: Ultrathin metal films on clean and well-defined oxide surfaces have been prepared by several groups using vapor deposition techniques in ultrahigh vacuum, and the structural, electronic and chemisorptive properties of these films have been characterized using a variety of surface science techniques. Those studies will be reviewed here, and trends in these properties will be identified. While films of mid- or late-transition metals can sometimes be grown in a quasi-layer-by-layer fashion at very low temperatures where kinetics prevail, heating these usually leads to thickening into the thermodynamically preferred structure: three-dimensional metal particles that cover only a fraction of the oxide surface. This occurs in two stages: individual island thickening, then Ostwald ripening. The kinetics of growth, nucleation and thickening will be examined. In some cases, this thermodynamic preference can be shifted to favor complete spreading of the metal film by adding gas molecules. This is driven by the higher adsorption energy of the molecule on the metal sites. Early transition metals which have very stable oxides can partially reduce the substrate oxide, and themselves become oxidized. The chemisorption properties of metal overlayers correlate well with their structural and electronic properties. Sites formed by neutral metal adatoms in these films on oxide surfaces often have chemisorption properties resembling that of some bulk metal crystalline plane. Surprisingly, this is even true for metal islands that are only one atom thick, in which case they resemble a very open or coordinatively unsaturated plane. However, the sites on and in the nearby oxide can alter the final surface chemistry, because adsorbates, especially hydrogen adatoms, can diffuse rapidly from the metal particles to these sites (spillover). While some real advances have already been made, many fundamental questions which are of great importance in oxide-supported metal catalysis and other fields remain to be addressed with this approach.

Abstract: The adsorption of Victoria blue, malachite green and methyl violet 6B on fresh hydrated ZrO2 prepared in various conditions was studied. Hydrated ZrO2 prepared by the addition of excess NaOH for precipitation shows the greatest adsorption capacity for the cationic dyes. The adsorption is considered to be mainly an ion exchange process. The effects of temperature and aging were also studied. Although a decrease in the adsorption capacity of hydrous oxide with aging was observed, the samples still showed good adsorption capacities for the dyes even after five weeks. Our investigations show the suitability of hydrated ZrO2 as an adsorbent for the removal of dyes from waste.

Abstract: Background: Reference errors in biomedical journals are well documented. Increasing use of electronic databases and bibliographic software May change the nature and frequency of errors. Aim: To study the current incidence of reference errors in four major general surgical journals. Methods: Seventy-five references were randomly selected from original articles published in one issue of each of four general surgical journals. For each reference, ease of retrieval on PubMed (TM) and the presence of citation errors were, noted. Two observers- independently reviewed each reference for quotation errors. Results: of the 300 Selected references, 261 from indexed English language biomedical journals were analysed. Retrieval from PubMed (TM) was impossible or difficult in six instances, giving a major citation error rate of 2.3%. Overall (major and minor) citation error rate was 11.1%. of the 258 references that could be retrieved, 20 (7.8%) had quotation errors, 80% of which were considered major. The overall citation error rate was significantly different across the four journals. There was moderate correlation between quotation error rate and number of references in each original article. Conclusion: Errors in references still appear in current surgical literature. Solutions to address this problem have been discussed.
