Advanced Materials Interfaces, EarlyView.Modification of geopolymer surface with a silane coupling agent containing quaternary ammonium group enables the development of dual‐functioning ion exchanger for both cations and anions. In the present study, the performance of this material was demonstrated for the uptake of ammonium and nitrate from water.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System
Advanced Science, EarlyView.An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Annals of Gastroenterological Surgery, EarlyView.Threshold‐optimized machine learning models using routine clinical and laboratory data in 623 adults undergoing appendectomy. Logistic regression (AUC = 0.765) and random forest (AUC = 0.785) were the best‐performing models for appendicitis detection and complicated appendicitis prediction, respectively.
