Dimensional Effect on the Lattice Anharmonicity in Graphene and Graphite

Xiao-ping Yao, Yuwen Zhang, Han‐Pu Liang, Ping‐Heng Tan et autres

ABSTRACT Dimensionality reduction is often expected to slow down the anharmonic decay of phonons since it drastically reduces the phase space for phonon‐phonon interactions. However, the anharmonic scattering behavior of the Raman‐active E 2g phonon in graphene deviates from this expectation when …

Repetitive unidirectional spinal tactile stimulation engages microglial Bmal1 pathways to promote synaptic remodeling in the mPFC of adolescent VPA-exposed mice

Yinan Chen, Mingxin Hu, Wu Li, Juan Yu et autres

Synaptic abnormalities are hallmark pathological features of autism spectrum disorders (ASD), contributing to the behavioral impairments frequently observed in these neurodevelopmental conditions. Microglia, as the brain’s primary immune cells, are essential for synaptic refinement during adolescent development. Disrupted microglia-dependent synapse remodeling has …

Size-Dependent Thermal Conductivity of Thick Low-Dimensional Silicon Nanostructures

Yufeng Huang, Chaofeng Hou, Wu Li, Gang Zhang et autres

In this work, using extreme-scale atomistic nonequilibrium molecular dynamics (NEMD) simulation, we simulate silicon nanostructures with a maximum characteristic size of 54.31 nm and a maximum length exceeding 5.2 μm, which contains up to 0.5 billion silicon atoms. The finite-length effects and …
