Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The basic C and C , and the higher fullerenes, mainly C and C , were extracted by original procedures, with p-xylene and the mixture of xylenes from the samples of initial carbon soot, produced in electrical arc. The extracts were obtained in increased and high yields of 6% and 11.9%, respectively, due to application of the advanced procedures. The solubility of fullerenes in these solvents was compared. Chromatographic separation of the basic and the higher fullerenes from the obtained p-xylene extract was performed by continue elution, in one phase of the process, under atmospheric pressure, with original, defined gradient of solvents, from pure hexane to 75% toluene in hexane, on active Al O column, by a new, improved method. Comparative spectroscopic characterization of the obtained purified fullerene fractions and the extracts is reported. The IR and UV/VIS techniques that have not been presented previously for the higher fullerenes were employed as a contribution to better introduction of their optical absorption properties.
