Scientists Publish A Newly Discovered State of Matter: Liquid Glass

By Madeleine Muzdakis on January 14, 2021 You probably know that there are three classically taught states of matter liquids, solids, and gases. However, the properties of certain materials defy simplistic categorization. For decades, scientists have sought to answer why glass lacks the crystalline molecular structure common to most solid materials. A recent paper published in the Proceedings of the National Academy of Sciences has made an important discovery which helps to explain this special property. As it turns out, a newly defined state of matter known as liquid glass is the key to understanding the structure of the commonplace solid-state material we all think we know well.

A new state of matter known as liquid glass has been discovered, and it s unreal

Physicist Matthias Fuchs and chemist Andreas Zumbusch from the University of Konstanz in Germany induced the liquid glass state in a lab by using colloids that they created themselves. After using particles in a shape that has never been experimented with before, they wanted to see what happened during the glass transition and got something worthy of Superman or Star Wars. “Suspensions of ellipsoidal colloids form an unexpected state of matter, a liquid glass in which rotations are frozen while translations remain fluid,” Fuchs and Zumbusch said in a study recently published in PNAS. “Image analysis unveils hitherto unknown nematic precursors as characteristic structural elements of this state. The mutual obstruction of these ramified clusters prevents liquid crystalline order.”

(such as a gel): homogeneous mixtures with particles that are microscopic but still bigger than atoms and molecules, and easier to study. In this case tiny, tailor-made plastic ellipsoidal colloids were created and mixed together in a solvent. This is incredibly interesting from a theoretical vantage point, says Matthias Fuchs, a professor of soft condensed matter theory at the University of Konstanz in Germany. Our experiments provide the kind of evidence for the interplay between critical fluctuations and glassy arrest that the scientific community has been after for quite some time. When materials transform from liquids into solids, their molecules usually line up to form a crystalline pattern. Not so with glass

Scientists discover new state of matter: Liquid Glass

Story highlights The scientists, in this research which was published in Proceedings of the National Academy of Sciences, focused on ellipsoidal polymethylmethacrylate colloids A team of scientists from Germany and the Netherlands have used a technology called confocal microscopy to discover a new state of matter, Liquid Glass, hidden inside mysterious transformations that happen between liquid and solid states of glass. Suspensions of colloidal particles are widely spread in nature and technology and have been studied intensely over more than a century, said co-senior author Professor Andreas Zumbusch, Department of Chemistry, University of Konstanz. When the density of such suspensions is increased to high volume fractions, often their structural dynamics are arrested in a disordered, glassy state before they can form an ordered structure.
