The sodium parts, represented by the green circles and chemical symbol Na, have a positive charge and dissolve in water. The long portion of the molecule, represented by the purple squiggle, has ...

In the mid-2000s, the introduction of the frustrated Lewis pair (FLP) concept marked a major advancement in catalysis, particularly in small molecule ... Lewis acid—and sodium (Na).

The positive areas of the water molecules surround the negative Chloride ions. The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a process during which the energy-rich molecule ATP is produced. Cells require ...

Leo Gross and colleagues examined molecules of pentacene (C 22 H 14) adsorbed on a copper(111) surface and on a sodium chloride film. With the STM, resolving atoms within an adsorbed molecule is ...
