The optical switches for single-mode operation cannot be directly utilized in communication and interconnect systems adopting mode-division multiplexing. In this paper, three general architectures on-chip space mode switching are proposed, which optimized switching, plus local global respectively.

Na-ion batteries (NIBs) have attracted increasing attention given the fact that sodium is relatively more plentiful and affordable than lithium for sustainable large-scale energy storage systems. However, shortage of electrode materials with outstanding comprehensive properties has limited practical implementations NIBs. Among all discovered anode materials, transition-metal sulfide been proven as one most competitive promising ones due to its excellent redox reversibility high theoretical...

Abstract Magnesium batteries have been considered promising candidates for next‐generation energy storage systems owing to their high density, good safety without dendrite formation, and low cost of magnesium resources. However, high‐performance cathodes with stable capacity, conductivity, fast ions transport are needed, since many conventional possess a performance poor preparation controllability. Herein, liquid‐driven coaxial flow focusing (LDCFF) approach preparing novel microcapsule...
Abstract The degradation of structural materials caused by the corrosion liquid lead‐bismuth eutectic (LBE), coolant lead‐cooled fast reactors (LFRs), has become one limiting factors for development LFRs.
