Abstract In this work, we report the electromagnetic absorption (EMA) properties of composites consisting of micrometer-sized cobalt with flowerlike architecture synthesized by a facile hydrothermal reduction method. Compared with the conventional spherical Co-paraffin composites, the flowerlike Co-paraffin composites are favorable with respect to EMA performance in the low frequency region, ascribing interfacial polarization loss and Ohmic loss to the improvement in the impedance match.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
