In this paper, we design and demonstrate a compact logic operator based on single-layer metasurface at microwave frequency. By mapping the nodes in trained fully connected neural network (FCNN) to specific unit cells with phase control function of metasurface, only one hidden layer is physically realized. When incident wave illuminates operating regions corresponding are activated can scatter two designated zones containing logical information output layer. The proposed experimentally...
<title>Abstract</title> Ionic transport in solids is critical for energy applications batteries and fuel cells. To improve ionic transport, an emerging approach the selective excitation of atomic vibrations related to mobile ions. However, there limited direct experimental evidence demonstrating enhanced macroscopic conductivity through this approach. Here, we used a 140-mW continuous-wave mid-infrared (MIR) light excite O–H stretch vibration proton-conducting yttrium-doped barium zirconate....
Proton conducting electrochemical cells (PCECs) are efficient and clean intermediate-temperature energy conversion devices. The proton concentration across the PCECs is often nonuniform, characterizing distribution of can help to locate position rate-limiting reactions.

Interactions of ceramic proton conductors with the environment under operating conditions play an essential role on material properties and device performance. It remains unclear how chemical material, as modulated by condition, affects conductivity. Combining near-ambient pressure X-ray photoelectron spectroscopy impedance spectroscopy, we investigate changes oxygen conductivity BaZr0.9Y0.1O3-δ condition. Changes in O 1s core level spectra indicate that adding water vapor increases both...
