Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

When Error Propagation Fails: A Mini‐Tutorial on Geometric Brownian Motion Simulation

Advanced Theory and Simulations, Volume 9, Issue 3, March 2026.
Linear error propagation fails in multiplicative stochastic processes governed by geometric Brownian motion, severely underestimating variance and tail risk. This mini‐tutorial derives the exact log‐normal solution, implements Euler–Maruyama simulation, and introduces a quantitative diagnostic for when simulation is essential.

Magnetic Resonance Imaging Reveals Meningeal Lymphatic Impairment in Lung Adenocarcinoma Brain Metastasis Progression

Advanced Science, Volume 13, Issue 16, 18 March 2026.
This study demonstrates meningeal lymphatic impairment associated with lung adenocarcinoma brain metastasis progression in both human patients and mouse models, establishes clinically applicable non‐invasive imaging biomarkers for quantitative analyzing mLV structure and function, and reveals mLVs as robust prognostic indicators and promising potential

OCTN2 Activates a Non‐Canonical Carnitine Metabolic Pathway to Promote MASH‐HCC Progression and Immunotherapy Resistance

Advanced Science, Volume 13, Issue 16, 18 March 2026.
In non‐MASH‐HCC, L‐carnitine promotes tumor progression primarily through its classical role in enhancing fatty acid oxidation (FAO). However, in MASH‐HCC, where FAO is markedly suppressed, L‐carnitine shifts from this canonical function to serve instead as an intracellular acetyl group buffer.

Overcoming Hole‐Extraction Barriers: A Facile PEDOT:PSS Interlayer Unlocks Record‐Low Voltage Deficit in PbS Quantum Dot Solar Cells

Advanced Science, Volume 13, Issue 16, 18 March 2026.
A synergistic methanol and oxalic acid interface engineering strategy is developed for PbS quantum dot solar cells. This approach transforms the PEDOT:PSS layer into a dense, electronically uniform, and conductive network. Consequently, the device achieves a record‐low voltage deficit of 340 mV, yielding a remarkable Voc of 742 mV and a power ...
