Perovskite LEDs are an emerging technology for next-generation display, lighting and communications. While perovskite LEDs can be produced simply and at low cost, they show clear technological advantages. They are lightweight and offer flexibility comparable to OLEDs, and they have color purity and...

After decades of inertial confinement fusion research, a yield of more than 1.3 megajoules (MJ) was achieved at Lawrence Livermore National Laboratory's (LLNL's) National Ignition Facility (NIF) for the first time on Aug. 8, 2021, putting researchers at the threshold of fusion gain and achieving...

A team based at Princeton University has accurately simulated the initial steps of ice formation by applying artificial intelligence (AI) to solving equations that govern the quantum behavior of individual atoms and molecules....

The graphite-diamond phase transition is of particular interest for fundamental reasons and a wide range of applications....

When humans, animals, and machines move throughout the world, they always push against something, whether it's the ground, air, or water. Until recently, physicists believed this to be a constant, following the law of conservation momentum. Now, researchers from the Georgia Institute of Technology...

Crystallization in liquids is a fundamental phase transition. While for many years, the understanding of crystallization was governed by classical nucleation theory, recent research has shifted focus to non-classical pathways in crystallization. In a new study, scientists from the Institute of...

In research that could broadly benefit science, medicine and engineering, a new kind of ultrasensitive optical sensing instrument has been developed by a doctoral student at The University of Alabama in Huntsville (UAH)....

In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles....

Manipulating solid particles of a few micrometers in size using an electric field has been of great interest to physicists. These controllable particles can be assembled into dynamic chains that can effectively control the flow of liquids in thin tubes like capillaries. Replacing these solid...

Stand up in a canoe and you'll probably find yourself in the water before too long. Jump up and down on the upper edges of the sides of the canoe, and you'll likely end up in the drink as well. But get the balance right and you'll be able to move yourself along by as much as one meter per second,...
