Single‐Particle FRET Probes Heterogeneity in the Ligand Shell of Colloidal Perovskite Quantum Dots

Advanced Materials, EarlyView.
Single‐particle, single‐molecule Förster resonance energy transfer turns dye‐tagged ligands into nanorulers for the otherwise elusive organic shell of CsPbBr3 quantum dots. Distance variations within individual particles reveal pronounced local heterogeneity, while changes in the surrounding ligand chemistry shift the average dye–surface separation ...

The Role of Slab Remnants in Modulating Free Subduction Dynamics: A 3‐D Spherical Numerical Study

Geochemistry, Geophysics, Geosystems
Seismic tomography of Earth's mantle images abundant slab remnants, often located in close proximity to active subduction systems. The impact of such remnants on the dynamics of subduction remains underexplored. Here, we use simulations of multi‐material

A Cu2S/NiOOH Heterojunction Enables Highly Selective Ammonia‐to‐Nitrite Electrooxidation at Industrially Relevant Current Densities

Advanced Materials, EarlyView.
Cu2S/NiOOH heterojunction enables efficient ammonia electrooxidation coupled with hydrogen evolution. Interfacial electronic modulation of Ni sites promotes selective NH3‐to‐NO2− electrooxidation at high current density. In a membrane electrode assembly, Cu2S/NiOOH maintains over 90% Faradaic efficiency of nitrite at 800 mA cm−2, highlighting its ...

Surface Segregation in Compositionally Complex Ag‐Au‐Pd‐Pt Solid Solutions: Insights From High‐Throughput Experimentation and Atomistic Simulations

Advanced Materials Interfaces, EarlyView.
Surface segregation in quaternary Ag‐Au‐Pd‐Pt compositionally complex solid solutions is systematically mapped across 684 compositions by combining high‐throughput EDX and XPS characterization of co‐sputtered thin‐film libraries with large‐scale MD/MC atomistic simulations.

Enhanced Magnetism in Cation‐Modulated Manganite Heterostructures

Advanced Materials Interfaces, EarlyView.
Magnetic contrast is introduced within a single manganite system via a small modulation of the cation ratio. Enhanced magnetization occurs in superlattices with small stoichiometric differences. The combined SQUID, polarized neutron reflectometry, and x‐ray absorption spectroscopy results are consistent with the interfacial electronic reconstruction ...

Engineering Ultra‐Low Fe or Ni Loading in Polymer Derived SiCN(O) Fibre Mats: Exploring the Performance towards Alkaline OER

Advanced Materials Interfaces, EarlyView.
Polymer‐derived SiCN(O) fibre mats enable anchoring of ultra‐low amounts of transition metals for efficient alkaline oxygen evolution. The distinct behaviour of Fe‐ and Ni‐based fibres highlights the importance of metal phase and support interactions in tailoring catalytic behaviour.

Structural Response of a Two-Side-Supported Square Slab Under Varying Blast Positions from Center to Free Edge and Beyond in a Touch-Off Explosion Scenario

Buildings
A touch-off explosion on concrete slabs is considered one of the simplest yet most destructive forms of adversarial loading on building elements. It causes far greater damage than explosions occurring at a distance.
