Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Wideband planar dipole based on dual-layer artificial magnetic conductor
A wideband planar dipole based on dual-layer artificial magnetic conductor (AMC) is designed. First, the size of dual-layer AMC is reduced by more than half, and the in-phase band is wider than the single-layer AMC.

Detailed study of the microwave emission of the supernova remnant 3C 396 [PDF]
We have observed the supernova remnant 3C~396 in the microwave region using the Parkes 64-m telescope. Observations have been made at 8.4 GHz, 13.5 GHz, and 18.6 GHz and in polarisation at 21.5 GHz.
