TL;DR: In this paper, the absorption properties of a thermoplastic natural rubber (TPNR), a lithium-nickel-zinc (Li-Ni-Zn) ferrite and a TPNR-ferrite composite were investigated.

TL;DR: In this paper, the TPNR matrix was prepared from polypropylene, natural rubber and liquid natural rubber (LNR) in the ratio of 70:20:10 with the LNR as the compatibilizer, and the absorption or minimum reflection loss continuously increases and the dip shifts to a lower frequency region with the increasing of both filler content in nanocomposites and the sample thickness.

TL;DR: In this paper, the specular absorber method is used in determining the reflection loss (R L ) of the absorber at different thicknesses, which would provide a feasible means of determining the frequency and thickness configuration for minimum reflection from the surface of an absorber.

TL;DR: In this article, a doped polyanilines (PAnis) was prepared at 0°C using different synthesized parameters such as different ratio of dopants like p-toluene sulphonic acid (pTSA) and dichloroacetic acid (DCA), oxidant (ammonium peroxydisulfate, APS) and various kind of solvents (H2O, HCl aqueous and H3PO4 annealous).

TL;DR: In this article, high coercivity magnetic nanoparticles (CoFe 2 O 4 ) have been synthesized by hydrolysis reaction in a micelle system followed by proper thermal annealing treatment to induce the crystallization.
