Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play ...

Water molecules are 10,000 times more sensitive to ions than previously thought, new research shows. Water molecules are made up of one negatively charged oxygen atom and two positively charged ...

When single particles like atoms and ions bond, molecules emerge. Such bonds between to particles can arise if they have for example opposite electrical charges and hence attract each other. The ...

Rydberg molecules and atoms comprise a captivating branch of modern quantum chemistry and atomic physics, where atoms in highly excited electronic states interact to form unusually long-range ...

Nanometer-scale pores etched into layers of graphene can provide a simple model for the complex operation of ion channels, researchers have demonstrated. Tiny pores at a cell's entryway act as ...
