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
Abstract: Oxidation of a mixture of Fe powder with polycarbonate based on bisphenol-A was studied on a Q500 thermogravimetric analyzer (TGA) after plastic deformation under a pressure of 10 and 25 kb in dynamic and isothermal heating modes. Analysis of the TGA curves of the resulting metal–polymer composite showed the presence of two sections: a section of weight loss and growth. Their temperature and weight values have been determined, and the baric dependence of these parameters has been established, including the oxidizability of the Fe powder. After programmed annealing of the metal–polymer mixture activated by deformation, a porous metal-oxide-polymer nanocomposite is formed, consisting of nanoparticles coated with a thin PC nanolayer (nanowires and hematite nanolayers), which grow vertically from iron particles reinforcing the surrounding polymer matrix. The presence of polycarbonate and its decomposition products on the surface of oxidized Fe particles was established. Removal of the formed “coating” increases the oxidizability of the metal. A decrease in the temperature of thermal decomposition of polycarbonate (from 400 to 270°C) during its interaction with the oxidized surface of iron particles is shown, which is explained by the high catalytic activity of one-dimensional hematite nanostructures formed during oxidation of iron particles.
