Creation of the most perfect graphene

A team of researchers led by Director Rod Ruoff at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS), including graduate students at the Ulsan National Institute of Science ...

Experimental confirmation of wave-particle duality

The 21st century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early 20th century and has been used to develop unprecedented technologies which include quantum information, quantum communication, ...

New mechanism of superconductivity discovered in graphene

Superconductivity is a physical phenomenon where the electrical resistance of a material drops to zero under a certain critical temperature. Bardeen-Cooper-Schrieffer (BCS) theory is a well-established explanation that describes ...

The birth of a subnanometer-sized soccer ball

Ever since the existence of molecules was proven and molecular reactions were predicted, humans have wanted to visually observe how such events proceed. Such observations of single-molecule reactions are highly important ...

Direct observation of coherence energy scale of Hund's metal

Strongly correlated systems are materials that exhibit strong interactions between electrons, a property unseen in ordinary conductors or insulators. Typical examples include metal-insulator transitions or unconventional ...

Seeing stable topology using instabilities

We are most familiar with the four conventional phases of matter: solid, liquid, gas, and plasma. Changes between two phases, known as phase transitions, are marked by abrupt changes in material properties such as density. ...

New catalytic approach to accessing key intermediate carbocation

Human civilization in the 21st century is largely sustained by modern chemical technologies. The raw materials used in the manufacturing of a wide range of products, from clothing to plastics and pharmaceuticals, are mainly ...
