Stacking‐Tuned Phonon Renormalization and Effective Heat Transport in Moiré Semiconductor Superlattices

ABSTRACT Optically driven moiré semiconductor bilayers involve coupled phonon anharmonicity, interlayer interactions, and local heat dissipation, but experimental benchmarks across supported homo‐ and heterobilayers remain limited. Here, we combine temperature‐dependent Raman spe...

Continuum limit of nonlocal electrostatics in random media

We derive a two-scale continuum limit for the electrostatic energy of random charge density fields that are stationary and ergodic under lattice translations. Each microscopic cell is charge neutral in every realization, while its dipole moment may fluctuate and have a nonzero me...

Series-Parallel Testing of Laboratory Lithium-Ion Cells: Not All Coin Cells Are Created Equal

Abstract This work evaluates parallel battery testing as a research tool for assessing both the reproducibility of laboratory-fabricated cells and the effects of cell-to-cell variation during pack-relevant operation. Eight hand-assembled CR2032 Li||LFP half-cells were tested usin...

Elemental analysis of geological materials: A review of XRF, LIBS, ICP-OES, ICP-MS, and AAS

Selecting an analytical technique for characterization of geologic material is a trade-off in sensitivity, elemental coverage, portability, and cost. This review discusses five important analytical techniques used in geochemistry: X-ray fluorescence (XRF) spectrometry, laser-indu...

Streamflow Prediction in Snow-Dominated Semiarid Watersheds Using a Cascade-Forward Deep Learning Approach

Abstract Accurate streamflow prediction in snow-dominated regions is challenging due to complex nonlinear interactions and significant temporal lags between snow accumulation and melt. This study evaluates the efficacy of a spatially explicit cascade-forward deep learning framewo...
