Deep-subwavelength broadband underwater sound absorption: Modeling, optimization, and mechanism elucidation
Low-frequency underwater noise absorption remains challenging because the large characteristic acoustic impedance and long wavelength in water make conventional porous/fibrous treatments impractical,...
Surface phenomena and fracture in Fe–(3 wt. %Si) single crystals with edge cracks (001)[110] on macro and atomic level
Fracture tests on single crystals with edge cracks (001)[110] (crack plane/crack front) of different lengths were performed at room temperature in tension mode I in a test machine with a cross head sp...
Quadratic magnetoresistance across the insulator–metal transition in V4O7 thin films
We present a comparative magnetotransport study of V4O7 thin films grown simultaneously on single-crystal Al2O3 (r-cut) and amorphous SiO2 substrates to examine substrate-induced effects on electronic...
The dependence of mode-locking characteristics for 1.5 <i>μ</i> m laser on the composition ratio of WTe2/MoS2 SA

We present and analyze results from a gridded ion thruster predictive engineering model (GIT PEM). The GIT PEM integrates coupled models of ion optics, erosion, electron backstreaming, and facility ef...
Quantifying the dislocation content of atomically resolved grain boundary line defects using the Nye tensor
The Nye tensor, which quantifies the density of Burgers vector for a given dislocation line direction, can be effectively used to characterize dislocation content in bulk crystals from atomic-resoluti...
Shear strain effects on metal–insulator transition of vanadium oxide V2O3
Vanadium oxide V2O3 is a strongly correlated transition-metal oxide, in which electrons are strongly coupled with the lattice system. It exhibits a first-order type of metal–insulator (MI) transition...
