Molding molecular matter(Nanowerk News) Scientists at Oak Ridge National Laboratory used a focused beam of electrons to stitch platinum-silicon molecules into graphene, marking the first deliberate insertion of artificial molecules into a graphene host matrix.
|The research was published in Carbon ("Electron-beam introduction of heteroatomic Pt–Si structures in graphene").|

|While scientists have already used the beam of a high-resolution electron microscope to intentionally rearrange graphene’s carbon-based molecular structure, this new development greatly enhances scientists’ ability to control matter at the atomic scale.|
|“This technique allows us to insert foreign molecules into the graphene lattice to change its physical properties,” said ORNL’s Ondrej Dyck.|
|He explained that this process is generally applicable and could be especially useful for prototyping quantum-based devices — including solid state qubits for quantum computers — from graphene and other ultra-thin materials.|
