Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

Advanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Mechanochemical Nitrous Oxide Decomposition

Advanced Materials, EarlyView.
Nitrous oxide (N2O) is a potent greenhouse gas with a global warming potential of 310. A novel mechanochemical strategy is presented for decomposing N2O into harmless nitrogen and oxygen, achieving a rapid decomposition rate of 1761.3 mL h−1 and nearly complete N2O conversion of 99.98% at 42 °C.

Linear and Symmetric Artificial Synapses Driven by Hydrogen Bonding for Accurate and Reliable Neuromorphic Computing

Advanced Materials, EarlyView.
Hydrogen‐bond‐driven interface engineering enables highly linear and symmetric artificial synapses based on CsPbI3–PVA hybrids. This strategy suppresses trap states and guides directional ion migration, yielding stable optoelectronic plasticity. The devices achieve ultralow power operation and human‐like learning in neuromorphic networks, offering a ...

Interface‐Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room‐Temperature Hopfions and Skyrmions

Advanced Materials, EarlyView.
The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.
