Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

open access: yesAdvanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Catastrophic Degradation in Solid Oxide Fuel Cells Caused by Air Supply Interruption in Real‐World Operations: Fundamental Mechanisms and Mitigation Strategies

open access: yesAdvanced Science, EarlyView.
Interrupting the air supply during the operation of solid oxide fuel cells leads to irreversible chemical degradation of the cathode materials, primarily driven by strontium at the A‐site of perovskite structures. Alternative strontium‐free materials effectively address this issue, ensuring high performance and reliable operation during operational ...

The Importance of Being Imperfect: Structure and Function of Bacterial Amyloid

open access: yesAdvanced Science, EarlyView.
Functional bacterial amyloids such as CsgA and FapC have been widely studied to understand the relationship between aggregation and function. The recently solved structure of FapC reveals a Greek‐key motif in which extensive hydrogen bonding and packing interactions formed by residues in conserved imperfect repeats stabilize a β‐solenoid core.

A Robust Solar Evaporator with Hierarchical Architecture for Ultrahigh Efficiency and Large‐Scale Zero‐Liquid‐Discharge Desalination

open access: yesAdvanced Science, EarlyView.
This study presents a low‐carbon footprint, robust 3D (three‐dimensional) evaporator featuring multi‐level low‐tortuosity channels for highly efficient desalination. It achieves an outstanding average evaporation rate of 8.1 kg m−2 h−1, salt collection rate of 1.95 kg m−2 h−1, and durability in high‐salinity brine.
