Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids
Advanced Materials, EarlyView.Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

True Closed‐Loop Recyclable Hydrogels Enabled by Imine Boronic Ester Crosslinking
Advanced Materials, EarlyView.Subtle molecular differences in imine boronic ester crosslinkers profoundly influence hydrogel properties. 2‐formylphenylboronic acid crosslinkers form previously undisclosed 3‐amino‐benzoxaborole heterocycles, enhancing elasticity despite lower crosslinking density compared to their 4‐formylphenylboronic acid counterparts.

Chiral Altermagnetic Magnetoelectrics
Advanced Materials, EarlyView.In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements
Advanced Materials, EarlyView.Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Advanced Materials, EarlyView.Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.
