Researchers have developed a technology that they say could make more efficient and eco-friendly refrigerators.

The problem is that carrying out these calculations on a computer is very slow, he says, "and the scaling is bad: If you double the number of electrons ... sulfur, chlorine, and even platinum.

Levels of chlorine, which is also toxic at low concentrations, reached 40 times the average. The spiking levels underscore the added danger from wildfires when cars, homes, and other structures ...

Ion chromatography can be utilized in various ways to analyze halogens and similar substances within inorganic matrices.

Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium ...

When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. Because chlorine is more reactive than bromine, it displaces ...

Scientists found a new quantum state in twisted graphene, where electrons lock in place but still conduct current along edges. This topological breakthrough may lead to advances in quantum computing.

Electrons have a hidden feature — spin — that could revolutionize technology. Magnets can control it, but researchers are now exploring chiral molecules as an alternative. These uniquely shaped ...
