A study of structural memory effects in synthetic hydrotalcites using environmental SEM
The ‘memory’ effect in synthetic hydrotalcite was demonstrated using d(001) and d(002) peaks in XRD patterns. These peaks were present in the hydrotalcite before it was calcined, and after it was reformed, but not in the thermally activated hydrotalcite. SEM images were taken of the hydrotalcite, to show the layering and size of the crystals. Environmental SEM (ESEM) images were taken of the thermally activated hydrotalcite, and then manipulation of temperature and pressure allowed water to condense on the sample. The ESEM images show that the layered structure is reforming following exposure to water.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
