Demonstrating a weak topological insulator in bismuth iodide

Topological insulators are one of the most exciting discoveries of the 21st century. They can be simply described as materials that conduct electricity on their surface or edge, but are insulating in their interior bulk. ...

Inner electrons behave differently in aromatic hydrocarbons

In an international research collaboration between Tsinghua University in Beijing and Sorbonne University in Paris, scientists found that four hydrocarbon molecules, known for their internal ring structure, have a lower threshold ...

Liquid jets break up more readily on a substrate

Whether we're aware of it or not, in day-to-day life we often witness an intriguing phenomenon: the breakup of jets of liquid into chains of droplets. It happens when it rains, for example, and it is important for inkjet ...

A fascinating phase transition from one liquid state to another

A team at the University of Tokyo has described in unprecedented detail the rare phenomenon of liquid-to-liquid phase transitions in a pure substance. By showing how a liquid made of just one type of molecule can switch between ...

Machine learning reveals rapid material classification

A research team at The University of Tokyo has developed a powerful machine learning algorithm that predicts the properties and structures of unknown samples from an electron spectrum. This process may rapidly accelerate ...
