Rational design of core-shell Co@C microspheres for high-performance microwave absorption
TLDR
In this paper, a uniform core-shell Co@C microspheres are innovatively fabricated through an in situ transformation from Co 3 O 4 @phenolic resin precursor, which can restrain the agglomeration of Co particles during high-temperature treatment, which accounts for the survival of uniform coreshell microstructure.About:

A facile fabrication and highly tunable microwave absorption of 3D flower-like Co3O4-rGO hybrid-architectures
TL;DR: In this paper, a 3D hierarchical Co3O4-rGO hybrid-architecture by a facile, green and highly tunable strategy is presented. And the result is attributed to utilizing multi-interface magnetic micro-flowers to tune impedance matching, which is accompanied with strong relaxation loss and electrical loss, as well as magnetic loss.
