A new model now describes the boiling process with much greater precision

22-Nov-2022

When a liquid boils in a vessel, tiny vapor bubbles form at the bottom and rise, transferring heat in the process. How these small bubbles grow and eventually detach was previously not known in any great detail. A German-Chinese research team under the leadership of the Helmholtz-Zentrum ...

This technique paves the way for large-scale hydrogen storage in solids

25-Oct-2022

Hydrogen gas could someday replace fossil fuels as a “clean” energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and converting it to a liquid requires vessels that can withstand extremely high pressures. Now, researchers reporting ...
