Boosting the sensitivity of NMR spectroscopy using parahydrogen
The low sensitivity of NMR spectroscopy can be enhanced via Para-Hydrogen Induced Polarization (PHIP). The parahydrogen (p-H2) is prepared by cooling H2 to cryogenic temperatures. At liquid N2 temperature, 52% p-H2 is obtained.

The science of levitation
Magnetic levitation occurs when the force on a diamagnetic object, due to an inhomogeneous magnetic field, is strong enough to balance the body’s weight resulting from the effect of the Earth’s gravity.
