Abstract A series of Rb x K 2− CaPO 4 F:Eu 2+ phosphors are synthesized using a high‐temperature solid‐phase method. An increase in the + concentration leads to Eu ‐excited phosphor emission spectra being shifted from red cyan. Interestingly, excitation spectrum does not exhibit any variations, which indicates possibility mixing (Rb 0.2 1.8 ) and cyan 2 for plant growth. This luminescence tuning is attributed substitution with , produces an inferior crystal‐field splitting that increases...

Ocean waves represent a vast, untapped source of renewable energy, yet current wave energy harvesting technologies often struggle with efficiency, cost, and scale. Triboelectric nanogenerators (TENGs) have emerged as promising devices for mechanical harvesting, but their application in conversion remains limited by challenges design performance. Here, we present novel swing-arm triboelectric nanogenerator (SA-TENG) specifically designed harvesting. Our device employs pendulum-inspired...
Abstract Soft robots based on stimuli‐responsive materials, such as those responsive to thermal, magnetic, or light stimuli, hold great potential for adaptive locomotion and multifunctionality in complex environments. Among these, liquid crystal elastomers (LCEs) magnetic microparticles have emerged particularly promising candidates, leveraging their thermal responsiveness controllability, respectively. However, integrating these modes achieve synergistic multimodal actuation remains a...

As an effective solution to the tradeoff between array size and number of antenna elements, dual-polarization is widely utilized in massive MIMO systems. However, existing channel state information (CSI) feedback schemes are not suitable for dual-polarized as they ignore polarization leakage directions, causing significant performance degradation. To facilitate accurate acquisition, this paper proposes a practical model by taking into consideration. The formulates sum two components, i.e.,...
