Cooperative motion by atoms protects glass from fracturing

Posted by in categories: materials, particle physics

We’ve all experienced the moment of panic when a glass slips from our hands, shattering into pieces upon hitting the ground. What if this common mishap could become a thing of the past?

Now, a new discovery by researchers at Tohoku University has offered insights into how resists breakage, potentially paving the way for highly durable, break-resistant materials. The breakthrough has wide ranging implications for glass-related industries.

Details of their findings are published in the journal Acta Materialia.

Revealing Hidden Worlds: Monochromatic Light Unveils the Secrets of Crystalline Drops

Posted by in categories: materials, particle physics

A new technique employing monochromatic light improves the study of internal structures in materials affected by light scattering, enabling detailed observation of particle concentrations.

When driving through a bank of fog, car headlights are only moderately helpful since the light is scattered by the water particles suspended in the air. A similar situation occurs when trying to observe the inside of a drop of milk in water or the internal structure of an opal gem with white light. In these cases, multiple light scattering effects prevent examination of the interior.

How can electrons split into fractions of themselves?

Posted by in categories: materials, quantum physics

MIT physicists have taken a key step toward solving the puzzle of what leads electrons to split into fractions of themselves. Their solution sheds light on the conditions that give rise to exotic electronic states in graphene and other two-dimensional systems.

The new work is an effort to make sense of a discovery that was reported earlier this year by a different group of physicists at MIT, led by Assistant Professor Long Ju. Ju’s team found that electrons appear to exhibit “fractional charge” in pentalayer graphene — a configuration of five graphene layers that are stacked atop a similarly structured sheet of boron nitride.

Ju discovered that when he sent an electric current through the pentalayer structure, the electrons seemed to pass through as fractions of their total charge, even in the absence of a magnetic field. Scientists had already shown that electrons can split into fractions under a very strong magnetic field, in what is known as the fractional quantum Hall effect. Ju’s work was the first to find that this effect was possible in graphene without a magnetic field — which until recently was not expected to exhibit such an effect.
