- In twisted graphene, some electrons are heavier than others
Researchers have discovered that in twisted graphene, electrons can exhibit different behaviors depending on momentum, acting as both heavy and light particles. This phenomenon occurs when two graphene layers are twisted at a specific angle. The study was published online in Nature.
- Electronic origin of reorganization energy in interfacial electron transfer
A study published in Nature reveals that tuning graphene's electronic density of states demonstrates the electrode's electronic structure, rather than the electrolyte, primarily controls reorganization energy. This finding shows how electrode structure governs outer-sphere electron-transfer rates at solid–liquid interfaces.
- Graphene just defied a fundamental law of physics
Scientists observed electrons in graphene flowing like a nearly frictionless liquid, defying a core law of physics. This breakthrough reveals new quantum behavior and could lead to advanced technologies.
