'Goldilocks size' rhodium clusters advance reusable heterogeneous catalysts for hydroformylation
Recent research has demonstrated that a rhodium (Rh) cluster of an optimal, intermediate size—neither too small nor too large—exhibits the highest catalytic activity in hydroformylation reactions. Similar to the concept of finding the "just right" balance, the study identifies
Asteroid 2024 YR4 has a 4% chance of hitting the moon. Here's why that's a scientific goldmine
There's a bright side to every situation. In 2032, the moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%) but are non-negligible. And scientists are starting to
