Mantle flow through a tear in the Nazca slab inferred from shear wave splitting
Geophysical Research Letters, 2017 A tear in the subducting Nazca slab is located between the end of the Pampean flat slab and normally subducting oceanic lithosphere. Tomographic studies suggest mantle material flows through this opening.

Sub-wavelength imaging with a left-handed material flat lens
, 2004 We study numerically, by means of the pseudospectral time-domain method, the unique features of imaging by a flat lens made of a left-handed metamaterial that possesses the property of negative refraction.

PbCrO4/Pb Hybrid with Surface Unsaturated Metal Sites for Efficient CO2‐to‐Formate Reduction
Advanced Functional Materials, EarlyView.An in‐operando electrochemically synthesized Vo‐rich PbCrO4/Pb hybrid exposes abundant unsaturated metal sites on PbCrO4 surface, which facilitates CO2 activation and stability of *OCHO intermediates. Simultaneously, the bulk Pb nanorod significantly enhances the conductivity of electrode for fast charge transport. The Vo‐rich PbCrO4/Pb electrocatalyst

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore
Advanced Functional Materials, EarlyView.To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Advanced Functional Materials, EarlyView.This study explores a cost‐effective alternative by incorporating oxophilic dopants into non‐precious metal hosts to enhance water dissociation and catalyst stability. Computational screening identified Ni─V, Ni─Mo, and Co─V as top candidates. Subsequent experiments confirmed Ni20V exhibits superior HER activity, achieving 76 mV lower overpotential ...

Interfacial Control of Degradation Pathways in 2D Heterostructures
Advanced Functional Materials, EarlyView.The stability of two‐dimensional (2D) heterostructures is governed not only by their intrinsic chemistry but also by interfacial effects. This study reveals how metallic versus insulating substrates impact the oxidation of air‐sensitive 2H‐MoTe2. Metallic layers act as charge reservoirs, mitigating degradation, while insulating ones accelerate it ...
