Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process produces per unit of fuel, physicists often compare how much of a substance’s ...

Chemical kinetics and reaction dynamics form the cornerstone of our understanding of how reactions proceed, detailing the temporal evolution of chemical processes from the microscopic to the ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

Traditionally, chemical reactions have been described as one-line “equations” in which substrates, say A and B, convert purposefully but rigidly into a desired product, say C. Naturally, it has been ...

Catalysts are essential to modern industry, accelerating reactions used to produce everything from fertilizers and fuels to medicines and hydrogen energy. But until now, scientists could not directly ...

The reaction generates amino acids and nucleic acids, the building blocks of proteins and DNA. Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by ...

Scientists have been naming ideas, theorems, discoveries, and so on after other scientists for a very long time (Newton’s laws of motion, anyone?). Chemists are no different. They’ve been naming ...

Sometimes a visually compelling metaphor is all you need to get an otherwise complicated idea across. In the summer of 2001, a Tulane physics professor named John P.

Researchers in Belgium have unveiled a striking chemical reaction in which ripples along a frozen reaction front resemble the rays of a shining star. Publishing their results in Physical Review ...
