Metallic Bond Induces Soft Phonon Mode and Anharmonicity in Heusler Alloy

Advanced Science, Volume 12, Issue 38, October 13, 2025.
The fruitful functional performances of metastable Heusler alloys originate from the martensitic transformation driven by the transverse acoustic soft phonon mode, regulated by anharmonicity. This study reveals that the long‐range interaction rooted in metallic bonding between spin‐down d‐orbitals of Ni─Ni induces phonon softening and significant ...

Understanding the Relevance of Percolation on Charge Transport in Random ZnO Nanowire Networks

Advanced Electronic Materials, Volume 11, Issue 16, October 6, 2025.
Conductivity in random nanowire networks remains challenging due to arbitrary geometries and conduction pathways. An innovative universalized percolation model combined with a shortest‐path algorithm addresses these limitations, accurately capturing tunneling and percolative conduction in ZnO nanowires.

Duality and the Renormalization Group

, 2006
The requirement that duality and renormalization group transformations commute as motions in the space of a theory has recently been explored to extract information about the renormalization flows in different statistical and field theoretical systems.

Cation Mg‐Dominated Coherent Phonon Transport Leads to Anomalous Thermal Conductivity in Mg3Bi2

Advanced Energy Materials, Volume 15, Issue 38, October 14, 2025.
Weakly bonded cation Mg atoms in Mg3Bi2 enhance coherent phonon transport, contributing 40% to thermal conductivity at 600 K. A unified theoretical framework and experimental validation reveal that strong anharmonicity from cation Mg suppresses particle‐like transport via four‐phonon scattering.

Decoding adipose–brain crosstalk: Distinct lipid cargo in human adipose‐derived extracellular vesicles modulates amyloid aggregation in Alzheimer's disease

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Obesity is a major modifiable risk factor for Alzheimer's disease (AD), but the mechanistic link between peripheral metabolic dysfunction and AD progression remains unclear. Adipose‐derived extracellular vesicles (EVs) may penetrate the brain and alter lipid homeostasis, contributing to neurodegeneration.

Functional renormalization group approach for signal detection

SciPost Physics Core
This review paper utilizes renormalization group techniques for signal detection in nearly continuous positive spectra. We emphasize the universal aspects of the analogue field-theory approach.
