The newly developed formalism and QFL splitting analysis led to new ways of characterizing extremely scaled-down semiconductor devices and the technology computer-aided design (TCAD) of next- generation nano-electronic/energy/bio devices.
GPS satellites ping smartphones and based on how long it takes for the signal to arrive, the GPS receiver in the smartphone can determine where the cell phone is.

The Transformational Challenge Reactor Demonstration Program uses thermal imaging to actively monitor the direct deposition of stainless steel to 3D print a component. The hexagonal structure took close to 40 hours to build, with temperatures reaching over 1,400 degrees Celsius around the melt pool where a laser heats and melts while adding a new layer.
Propagation of an "ultra-lean" hydrogen flame in a very narrow combustion chamber. The images on the left show a flame propagating vertically downward; those on the right are burning in the opposite direction. The dark markings show the path followed by the flame, while the lighter parts show the hydrogen that has not been burned.
David Storm, a research physicist, and Tyler Growden, a National Research Council postdoctoral researcher, at the U.S. Naval Research Laboratory with their molecular beam epitaxy system that develops gallium nitride-based (GaN) semiconductors in Washington, D.C., March 10, 2020. Storm and Growden published their research on GaN semiconductor materials, which showed high yield and performance well suited for high frequency and high power electronic devices in Applied Physics Letters.
This is defective graphene.
A new computer vision algorithm for identifying particles in a lithium-ion battery cathode has helped researchers track the cathode's degradation over time.
A Korean research team has developed a large-scale stretchable and transparent electrode for the stretchable display. The Korea Institute of Science and Technology (KIST) announced that a research team has developed a technology to fabricate a large-area wavy silver nanowire network electrode that is structurally stretchable with a high degree of conductivity and transparency.
