Autocatalysis has been extensively studied because it is central to the propagation of living systems. Chemical systems which self-reproduce like living cells would offer insight into principles ...

On the move: time sequence of the electron distribution of the molecule 1,3-cyclohexadiene after it is excited by a light pulse. (Courtesy: SLAC) Scientists in the US and UK are the first to observe ...

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 ...

Researchers in the US have shown that mechanical force can bring about unique chemical reactions. Their experiment involved pulling on molecules in solution using ultrasound and suggests that ...

The terms reaction rate, chemical kinetics, and effective collisions are defined. Reaction Rates: The terms reaction rate, chemical kinetics, and effective collisions are defined. Students learn the ...

Students learn how to predict the products of a chemical reaction. Types of Reactions: Students learn how to indicate the state of a substance in a chemical equation. The major types of reactions are ...
