Two Distinct Phonon Wave Effects Control Thermal Transport across the Coherent–Incoherent Regime in Superlattices

Advanced Science, EarlyView.
Thermal transport in smooth‐interface superlattices is studied using the phonon Wigner transport equation, which captures both particle‐like and wave‐like contributions. A minimum in cross‐plane thermal conductivity emerges with increasing period thickness, signaling a crossover from coherent to incoherent phonon transport.

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

Advanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide

Advanced Science, EarlyView.
K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Origins of Graphite Resistivity: Decoupling Stacking Fault and Rotational Misorientation

Advanced Science, EarlyView.
Interfacial dislocations critically influence interlayer transport in van der Waals (vdW) materials, yet quantifying their individual contributions remains challenging. We measure graphite's c‐axis resistivity and develop a decoupling strategy, revealing a resistivity ratio of ∼4507:74:1 for rotational misorientations, stacking faults, and AB stacking,
