Graphite ‘hijacks’ the journey from molten carbon to diamond

Machine-learning-based molecular simulations reveal unexpected crystallization pathway

Series of diagrams showing different stages of graphite and diamond as they crystallize. A left to right arrow labelled "nucleation pathways" indicates the direction of progress of crystallization through the series. Graphite, shown in red, gradually forms stacks of disorderly rings. Diamond, shown in blue, gradually forms larger and larger regular crystals

Mysterious seismic wave speed-up deep within Earth’s mantle explained at last

A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself

Two diagrams, one showing a "pie slice" cross-section of the Earth with the core on the inside and the lower mantle, upper mantle and thin crust above it, and the other showing a zoomed-in image of an area just above the lower mantle-core boundary. The zoomed-in image contains two scenarios. The first scenario shows the post-perovskite randomly oriented and labelled "no mantle flow" and "no discontinuity". The second shows the post-perovskite aligned and is labelled "mantle flow" and "D" discontinuity".

Has bismuth been masquerading as a topological material?

New research explains previous contradictory observations in terms of “topological blocking”, which may occur in other materials, too
