Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...
4D scanning transmission electron microscopy (4D STEM) is a subset of scanning transmission electron microscopy (STEM) which utilizes a pixelated electron detector to capture a convergent beam electron diffraction (CBED) pattern at each scan location. This technique captures a 2 dimensional reciprocal space image associated with each scan point ...

A Houston man was sentenced to 30 years in prison after pleading guilty to sexually exploiting a 9-year-old and being a dark web administrator for a website that consisted of child sex abuse ...
A four-dimensional product (4D product) considers a physical product as a life-like entity capable of changing form and physical properties autonomously over time. It is an evolving field of product design practice and research linked to similar concepts at the material scale (programmable matter and four-dimensional printing), however, typically utilizes sensors and actuators in order to ...
For the cadets and midshipmen on the field, a career playing professional football is unlikely. This game is their Super Bowl. “It represents a battle between two of the nation’s best forces ...
Cleveland kept pressure on throughout the fourth quarter and repeatedly cut the Boston lead to two points. But the Celtics answered every time and never allowed the Cavs to take the lead.
