(Phys.org) —The simple acts of heating and cooling affect different substances in different ways: some substances may change phase from solid to liquid to gas, while others may irreversibly break down when heat is applied. ...
Crystals are not as stationary as you might think. A crystal of an organometallic compound containing palladium, for example, downright jumps from a hotplate once it reaches certain temperature. An international team of scientists, ...

(Phys.org) —A team of chemists working in Germany has finally, after decades of debate, solved the crystal structure of the nonclassical 2-norbornyl carbocation. In their paper published in the journal Science, the team ...
A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain ...
