Scientists investigate how cerium is produced in the universe

 Physics General News
 21 March 2024
Cerium is a rare Earth metal that has numerous technological applications, for example, in some types of lightbulbs and flat-screen TVs. While the element is rare in Earth's crust, it is slightly more abundant in the universe. However, much is unknown about how it is synthesized in stars....

DNA attached to nanoparticles found to contribute to lupus symptoms

 Nanotechnology News
 21 March 2024
Autoimmune diseases are mysterious. It wasn't until the 1950s that scientists realized that the immune system could harm the organs of its own body. Even today, the fundamental causes and inner workings of most autoimmune diseases remain poorly understood, limiting the treatment options for many of...

New method for analyzing nanoporous materials

 Nanotechnology News
 21 March 2024
In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure. This applies to high-tech materials used in sensor or separation technology as well as to natural...

An approach to design high-power lithium sulfur batteries

 Nanotechnology News
 21 March 2024
Lithium–sulfur (Li–S) batteries are a promising alternative to lithium–ion batteries (LiBs), the most common rechargeable battery technology. As sulfur is abundant on Earth, these batteries could be cheaper and more environmentally friendly than LiBs, while also potentially exhibiting higher energy...

High-quality microwave signals generated from tiny photonic chip

 Physics General News
 20 March 2024
In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device—a chip so small, it could fit on a sharp pencil point—results in the lowest microwave noise ever...
