Size Effect on Photothermal Heating Ability of Gold Bipyramids

open access: yesAdvanced Optical Materials, EarlyView.
Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Near Room‐Temperature Ferromagnetic Phase Achieved in 4d Ruthenate via Interfacial Ferrimagnetic Coupling and Octahedral Rotation Engineering

open access: yesAdvanced Science, EarlyView.
Transition metal oxides combining strong spin‐orbit coupling, near‐room‐temperature ferromagnetism, and high conductivity are rare. A Ca0.5Sr0.5RuO3 interfacial phase between LaMnO3 layers has all these features, high Tc, enhanced magnetization, and reduced coercivity.

Observation of Magnetic Pseudogap Behavior in Phosphorus‐Doped Silicon

open access: yesAdvanced Science, EarlyView.
Phosphorus‐doped silicon presents a promising platform for quantum computing and hosts a Kondo condensate state featuring a pseudogap. Thermodynamic and magnetic resonance measurements reveal that this pseudogap behavior involves critical spin fluctuations, suggesting that overlapping Kondo clouds form a correlated coherent magnetic ground state ...

Enhancing Cycle Stability in LiNiO2 with Phase transition suppression via Crystalline Disordered Surface Layer

open access: yesAdvanced Science, EarlyView.
The thickness of the disordered surface phase on single‐crystal LiNiO2 is controlled during synthesis. LiNiO2 with a crystalline disordered surface layer exhibits suppression of the H2–H3 phase transition. This mitigates structural degradation with improved cycling stability.
