Fluorophores are chemical compounds or molecules that absorb light energy at one wavelength and re-emit it as light at a ...

Light-emitting semiconductors are used throughout everyday life in TVs, smartphones, and lighting. However, many technical ...

Overview Energy emerged from stealth today with a plan to use the world’s solar panels as nighttime collectors of power beamed down from space. The startup plans to use large solar arrays in ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Fourier transform infrared (FTIR) spectroscopy is the preferred method of infrared spectroscopy. In this approach, IR radiation passes through a sample, where some of it is absorbed by the sample ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

As the federal government reimagines American energy policy this year, support for projects hinges on a new metric — density. The concept of density in energy production echoes throughout recent ...

For decades, fuel cell innovation has been guided by two main benchmarks: cost per kilowatt and stack durability. These remain important, especially in applications driven almost entirely by project ...

For the first time, scientists have used the James Webb Space Telescope (JWST) to study the origins of a bizarre, record-breaking radio signal that flashed past Earth earlier this year. Tracking the ...

In 1956, the American geologist M. King Hubbert made a startling prediction: In a matter of decades, the supply of fuel on which so much of modern society depended would dwindle. Dubbed the “peak oil” ...
