'Trump is geen protestpresident': Sara Polak legt het uit bij de Universiteit van Nederland
Het is misschien waar dat veel 'boze' Amerikanen op Donald Trump stemden, maar dat maakt hem geen protestpresident, aldus universitair docent Sara Polak. Trump is een antagonistische president - een tegenwerker van het huidige systeem - die zich omringt met revolutionairen. En dat is uniek. Ze vertelt…

Towards in-cell structural study of light-harvesting complexes : an investigation with MAS-NMR
Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

Knots in plasma
A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.
