Atomic-scale determination of surface facets in gold nanorods [PDF]
, 2012 It is widely accepted that the physical properties of nanostructures depend on the type of surface facets1, 2. For Au nanorods, the surface facets have a major influence on crucial effects such as reactivity and ligand adsorption and there has been ...

Reconstruction of myocardial tissue motion and strain fields from displacement-encoded MR imaging
American Journal of Physiology-Heart and Circulatory Physiology, 2009 A quantitative analysis of myocardial mechanics is fundamental to understanding cardiac function, diagnosis of heart disease, and assessment of therapeutic intervention. Displacement encoding with stimulated-echo (DENSE) magnetic resonance imaging (MRI) technique was developed to track the three-dimensional (3D) displacement vector of discrete ...

Intragranular strain estimation in far-field scanning X-ray diffraction using a Gaussian process
, 2021 A new method for estimation of intragranular strain fields in polycrystalline materials based on scanning three-dimensional X-ray diffraction (scanning 3DXRD) data is presented and evaluated. Given an a priori known anisotropic compliance, the regression

Physics‐Informed Deep‐Learning For Elasticity: Forward, Inverse, and Mixed Problems
Advanced Science, 2023 Elastography is a medical imaging technique used to measure the elasticity of tissues by comparing ultrasound signals before and after a light compression. The lateral resolution of ultrasound is much inferior to the axial resolution.
