If you cool a solid, the molecules move more slowly and move a little closer together. Step 2 Show an animation to help students compare atoms and molecules in solids and liquids. Explain that the ...

The inherent magnetic characteristics of atomic nuclei can be targeted to uncover the structure, identity, concentration, and behavior of molecules in both solid and liquid samples ... which ensures ...

Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives ...

Scientists have studied the vibration of four gases using electron microscopy and spectroscopy. Combined with simulations, they measured the increased vibration at 1,000°C compared with room ...

As water freezes, the attractions the water molecules have for one another overcome their motion and hold them in fixed positions. ... Water molecules move further apart as liquid water becomes solid ...

For interfacial water molecules, the bending vibration has been reported to be red-shifted, with respect to bulk water 42. ... Such fits are shown as solid lines in Supplementary Fig. 4.

Water’s just plain old water, right? Not when you trap it inside a tiny channel, it seems, because then it behaves like no other solid, liquid or gas.

With a 3-D model, there's no way for two solid molecules to go right through each other. Olson is using the 3-D-printed models to understand the function of HIV, ...

Complex carbon-based molecules are everywhere in the Cosmos.  How many of these molecules are formed is still something of a mystery, particularly for carbon molecules formed by nature on ...
