The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

More than 150 million metric tons of propylene are produced annually, making it one of the most widespread chemicals used in ...

A new map of cosmic expansion suggests that dark energy evolves over time, hinting that the universe doesn’t work the way we ...

Scientists are conducting experiments to generate clean energy through fusion, the same sub-atomic reaction that powers our Sun, with the aim of constructing plants that produce more energy than they ...

Metamaterials are materials that possess exotic properties, and the metamaterial assembled at the École Polytechnique ...

The researchers hit the chamber with a magnetic field, causing the atoms inside to experience shifts in energy. They then used a laser to precisely measure those shifts. "You can think of each ...

3 min read Solar energy is the technology used to harness ... When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate ...

Cold atoms are atoms that have been cooled to very low temperatures, below 1 mK, reducing their motion to a very low energy regime where quantum effects emerge. This makes them sensitive to some ...
