Using Powerful Laser Pulses to Modify the Shape and Properties of Graphene

Graphene is a new exciting material, which has been characterized as "the wonder material" because of its excellent properties. Graphene gained widespread attention in 2010 when Nobel Prize in physics was awarded to researchers who discovered it. Graphene is only one atom layer thick making it the world's thinnest material.

Using X-ray Free Electron Laser and AI to Observe 3D Structure of Virus

It is millions of trillions of times brighter than the sunlight and a whopping 1,000 trillionth of a second, appropriately called the instantaneous light. It is the X-ray Free Electron Laser (XFEL) light that opens a new scientific paradigm. Combining it with AI, an international research team has succeeded in filming and restoring the 3D structure of nanoparticles that share structural similarities with viruses.
