Phase Engineering of Nanomaterials (PEN): Evolution, Current Challenges, and Future Opportunities
Advanced Materials, EarlyView.This review summarizes the synthesis, phase transition, advanced characterization spanning ex situ to in situ and operando techniques, and diverse applications of phase engineering of nanomaterials (PEN). It further outlines key challenges and future opportunities, such as phase stability, architecture control, and artificial intelligence (AI)‐driven ...

Highly Entangled Bottlebrush Polymer Networks
Advanced Materials, EarlyView.Bottlebrush polymers are difficult to entangle, enabling ultrasoft yet brittle networks. We report highly entangled bottlebrush elastomers that remain ultrasoft (∼1 kPa) yet stretch to ∼1800% and exhibit exceptional fatigue resistance. Their intrinsic fatigue strength—fatigue threshold normalized by modulus—surpasses that of highly entangled linear ...

Advanced Materials, EarlyView.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Advanced Materials, EarlyView.A sustainable δ‐lactone‐based polymer platform enables multimodal additive manufacturing through DLP, DIW, and FFF, combining tunable crystallinity, photocurable networks, mechanical robustness, and functional response. The printed materials can be mechanically reprocessed and chemically depolymerized into recoverable monomers, demonstrating a closed ...

Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures
Advanced Materials, EarlyView.Coherent isostructural high‐entropy oxide heterostructures are realized despite remarkable >5% interfacial lattice distortion. The resulting buried interface exhibits abrupt valence reconstruction which contributes to 2 × enhanced exchange bias in the heterostructure relative to constituent layers, demonstrating how chemical disorder enabled anomalous ...

Abstract An acoustically hard surface has reflection coefficient of +1 for all angles of incidence. A surface characterized by an impedance boundary condition, on the other hand, has a reflection coefficient which is a function of the angle of incidence. In particular, an impedance surface has a reflection coefficient of −1 at grazing

DURING research on the contact of solid surfaces we have been examining the deformation under load of single asperities. These are formed by turning cones of base diameter about 0.2 mm on metal surfaces and are pressed against a hard anvil under known loads. The resulting flats are examined by relocation profilometry1 and by optical microscopy.
