Incompressible electrons

Helium usually reminds people of colorful gas balloons. However, helium is much more than the filling for these children's treats.  It also helps quantum physicists to study the most exotic and hidden properties of matter. ...

Treating pulmonary diseases using Alaska pollock gelatin

In recent years, patients with pulmonary emphysema have been increasing mainly among middle-aged and elderly males due to aging and excessive smoking. Emphysema makes brittle lungs, and in severe cases, holes develop in the ...

Two-dimensional semiconductor comes clean

In 2013 James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, and colleagues at Columbia demonstrated that they could dramatically improve the performance of graphene—highly conducting two-dimensional ...

Improving the theory of phase transitions with supercomputers

When water molecules evaporate from a liquid phase into a gaseous phase, they alter their aggregate state. The mathematical description of such a phase transition harbours pitfalls as nucleation is needed for the change to ...
