Green hydrogen: Why do certain catalysts improve in operation?

As a rule, most catalyst materials deteriorate during repeated catalytic cycles—they age. But there are also compounds that increase their performance over the course of catalysis. One example is the mineral erythrite, ...

X-ray study reveals how lead sulphide particles self-organise in real time

The structure adopted by lead sulfide nanoparticles changes surprisingly often as they assemble to form ordered superlattices. This is revealed by an experimental study that has been conducted at DESY's X-ray source PETRA ...

Thinking without a brain: Studies in brainless slime molds reveal that they use physical cues to decide where to grow

If you didn't have a brain, could you still figure out where you were and navigate your surroundings? Thanks to new research on slime molds, the answer may be "yes." Scientists from the Wyss Institute at Harvard University ...

Model predicts when rivers that cross faults will change course

As tectonic plates slip past each other, the rivers that cross fault lines change shape. The shifting ground stretches the river channels until the water breaks its course and flows onto new paths.
