Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

Advanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

Advanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

Advanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

Band Alignment of Grafted Si/Ge0.89Sn0.11 Heterojunction Determined by X‐Ray Photoelectron Spectroscopy

Advanced Materials Interfaces, EarlyView.
ABSTRACT We investigate the band alignment of a monocrystalline grafted p‐type Si/Ge0.89Sn0.11 heterostructure using X‐ray photoelectron spectroscopy (XPS). The bandgap of the Ge0.89Sn0.11 epilayer of 0.50 eV was first determined and cross‐verified using photoluminescence spectroscopy, infrared transmission, and theoretical calculation.
