ULF Multi‐Key Tunable Magnetoelectric Antenna Array with Enhanced Communication Data Rate

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a reconfigurable magnetoelectric antenna with a dual‐asymmetric cantilever structure. By adjusting its fixed boundary conditions, the antenna's resonant frequency is tunable over a 500 Hz range within the ultra‐low‐frequency (ULF) band.

Integrated Green Biorefinery for the Production of Anthocyanins, Fermentable Sugars, and High Pure Lignin from Miscanthus × giganteus

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Integrated production of pigments, fermentation sugars, and pure lignin has been investigated for the creation of profitable biorefinery developments. Choline chloride‐based natural deep eutectic solvents possess unique solvent capabilities to interact with plant cell wall components to disintegrate lignin‐carbohydrate complex.
