In short, 4D ultrasound imaging is a 3D ultrasound in live motion. 4D ultrasounds utilize either a 2D transducer, which rapidly acquires 20-30 volumes or a matrix array, which instead uses a 3D ...

Unlike stacked 2D materials, whose orientations can be relatively easily changed by simply picking up one layer, twisting it slightly, and placing it down again, the bonds holding 3D materials ...
