Researchers have found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals. Researchers ...

A stable cluster of aluminum atoms, Al13, acts as a single entity in chemical reactions, demonstrating properties similar to those of a halogen, reports a research team led by A Welford Castleman Jr., ...

Hafnium oxide (HfO 2) has attracted attention as a promising material for ultrathin semiconductors and other microelectronic devices. The strong ionic bond between hafnium and oxygen atoms in HfO 2 ...

Halogen atoms (Cl and Br) strongly influence the atmospheric chemical composition. Since 1970s, scientists discovered that these atoms were responsible for depletion of ozone in the stratosphere and ...

In the realms of supramolecular chemistry, crystal engineering, and biology, noncovalent interactions play a critical role in shaping three-dimensional structures. Hydrogen bonds are the most well ...

Before you read any further, think of a few organohalogen compounds commonly found in the environment. If you're like most people, your first thought will be man-made pollutants such as ...
