Intrinsic Phonons as a Dynamic Control Knob for Catalytic Reactivity in 2D Materials

Advanced Science, EarlyView.
Intrinsic phonon excitations are demonstrated to serve as a dynamic control knob for catalytic reactivity in 2D materials. Mode‐selective lattice vibrations reconstruct the electronic structure, lower oxygen evolution reaction barriers, establishing a phonon‐engineering paradigm for dynamically regulating electrocatalysis beyond conventional static ...

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Dynamically Tunable Exciton‐Photon Coupling via Multi‐Physics Field in Transition Metal Dichalcogenide Microcavities

Advanced Science, EarlyView.
Dynamic microcavities provide reversible control over exciton‐photon coupling in two‐dimensional TMDs through piezoelectric, electrical, thermal, and all‐optical tuning. By reshaping detuning, Rabi splitting, and polariton composition, these strategies enable adaptable polaritonic functions, including optical switching, polariton lasing, and ...

Sobre la electrodinámica de los cuerpos en movimiento

Memoria Investigaciones en Ingeniería, 2005
Es bien conocido que la electrodinámica de Maxwell—como se le entiende usualmente en la actualidad—aplicada a los cuerpos en movimiento, conduce a asimetrías que no parecen ser inherentes a los fenómenos.

High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

Advanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

Advanced Science, EarlyView.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

Effective Solvent‐Engineered All‐Inorganic CsPbI2Br Perovskite Solar Cells

Advanced Science, EarlyView.
All‐inorganic CsPbI2Br perovskite composition has gathered a lot of attention in recent years due to its thermal robustness, convenience for space applications as well as for the all‐perovskite triple junction applications as a top cell due to its wide‐bandgap (1.9 eV) nature.

Emergent Magnetism, Heavy Electrons, and Pressure‐Induced Reentrant Superconductivity in the Iron Substituted 4d Transition‐Metal Sulfides

Advanced Science, EarlyView.
This work illustrates that magnetic Fe substitution enables systematic modulation of physical properties of the putative unconventional superconductor Rh17S15. Iron doping uncovers delicate competition between weak ferromagnetism, spin‐glass states, heavy‐fermion signatures, and superconductivity.
