Scientists study catalytic properties of individual gold nanoparticles

Before you can design the perfect nanoparticle catalyst, you first need to understand the fundamental science that governs their reactivity, say scientists from the US. And they claim to have done just that, using single molecule spectroscopy to reveal that nanocatalyst surface properties respond to changes to the concentration of reactants.

Previously impossible alloys can be created by subjecting atoms to high pressure

A lot of high pressure materials can be made, but once the pressure is reduced they go back to their original form. People cannot make anything useful from those materials. But a new alloy is quenchable, meaning that the alloy persists when the pressure is gone.
