Pauling's Rules describe the principles governing the structure of complex ionic crystals. These rules essentially describe how the arrangement of atoms in a crystal is critically dependent on the size of the atoms, their charge and type of bonding. According to scientists, similar rules can be applied to prepare ionic colloidal crystals consisting of oppositely charged proteins and virus particles.

One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers around the world have made all sorts of attempts to achieve this, but now scientists have succeeded in creating a steady stream of photons emitted one at a time and in a particular direction.

Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now researchers have for the first time captured atoms in borosilicate glass flipping from one structure to another as it is placed under high pressure.
