5G new radio multiuser precoding in geostationary satellite networks

International Journal of Satellite Communications and Networking, EarlyView.
This work evaluates the standardized 5G new radio codebooks for closed‐loop multiuser precoding in GEO multibeam scenarios and derives a list of recommended 3GPP standard modifications for a proper support to GEO mission needs. Summary The multiuser precoding procedures standardized by the 3rd Generation Partnership Project (3GPP) for new radio (NR ...

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

Strain Engineering of Twisted Bilayer Graphene: The Rise of Strain‐Twistronics

Small, EarlyView.
This review summarizes the recent advances in the strain engineering of twisted 2D materials, in particular twisted bilayer graphene, toward effectively modifying their Moiré superlattices and tuning electronic structures upon mechanical straining.

Ultrasmall 2D Sn‐Doped MAPbBr3 Nanoplatelets Enable Bright Pure‐Blue Emission

Small, EarlyView.
This study introduces a novel room‐temperature method for synthesizing ultrasmall Sn‐doped MAPbBr3 nanoplatelets that exhibit pure blue emission with a narrow full width at half maximum. This result is achieved by incorporating octylamine into both the precursor and antisolvent to suppress rapid growth.

Tunable Hypersonic Resonators via Electron‐Irradiation‐Induced Giant Modulation of Microparticle Elasticity

Small, EarlyView.
A strategy is presented to tune the elastic properties of Stöber silica microparticles, widely used in phononic materials, by exposing them to moderate electron beam energies. This results in rapid elasticity changes, investigated via Brillouin light scattering, and attributed to radiation‐induced stiffening.
