Chemists fabricate 'impossible' material - 0 views

  •  
    When atoms combine to form compounds, they must follow certain bonding and valence rules. For this reason, many compounds simply cannot exist. But there are some compounds that, although they follow the bonding and valence rules, still are thought to not exist because they have unstable structures. Scientists call these compounds "impossible compounds." Nevertheless, some of these impossible compounds have actually been fabricated (for example, single sheets of graphene were once considered impossible compounds). In a new study, scientists have synthesized another one of these impossible compounds -- periodic mesoporous hydridosilica -- which can transform into a photoluminescent material at high temperatures.

Timid and shy or bold and welcoming, water behaves in unexpected ways on surfaces - 0 views

  •  
    It's ubiquitous. It's universal. And it's understood-not! Water's choices in a given situation often defy scientific predictions. When expected to bond with other water molecules, it shuns them. When expected to ignore a surface, it becomes deeply attached. However, research at Pacific Northwest National Laboratory has revealed why one of the simplest and most important molecules on the planet makes some of the decisions it does.
