Frost, Ray L., Reddy, S. Lakshmi , Reddy, N.C. Gangi , Reddy, R. Rama Subba , Reddy, G. Siva , & Reddy, B. Jagannatha (2006) Characterization of Red sandalwood by ICP-MS Analysis, Optical absorption and EPR spectroscopic methods. Radiation Effects and Defects in Solids, 161(9), pp. 537-547.
Red sandalwood contains Cd, Fe, Ni, Mn, C, S, H elements. ICP-MS results indicate that the red sandalwood contains Ni (61.877), Cu (281.256), Ba (3722.064) and Sr (6365.482) ppm elements respectively. It has partial semi conducting nature. EPR spectrum of the sample is due to Fe(III) in tetragonal distortion and its ash sample also contains Mn(II) in addition to Fe(III). The g values obtained for Fe(III) in the sample are 6.52, 2.63 and 1.92 respectively. The observed g and A values for Mn (II) are 1.990 and 88.5 G respectively. Mn(II) may be low in concentration in the sample. Optical absorption spectrum clearly indicates the presence of both ferric iron and Ni(II) in octahedral geometry. NIR Spectrum is due to carbonate overtones and harmonics and water fundamentals.
Impact and interest:
Citation countsare sourced monthly fromand 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 downloadsdisplays 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.
