The magic angle of twisted graphene

Graphene, a two-dimensional material composed exclusively of carbon, has revealed extraordinary properties, including thermal and electrical conductivity, transparency, and flexibility. When combined, these properties become ...

The quest for the magic angle

Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use ...

'Forward' jet-tracking components installed at RHIC's STAR detector

Just prior to the start of this year's run at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE's Brookhaven National Laboratory—a ...

A powerful, pocket-sized optical imager, no longer science fiction

Before Wilhelm Röntgen, a mechanical engineer, discovered a new type of electromagnetic radiation in 1895, physicians could only dream of being able to see inside the body. Within a year of Röntgen's discovery, X-rays were ...

New microscopy concept enters into force

The development of scanning probe microscopes in the early 1980s brought a breakthrough in imaging, throwing open a window into the world at the nanoscale. The key idea is to scan an extremely sharp tip over a substrate and ...

New piezoelectric material remains effective to high temperatures

Piezoelectric materials hold great promise as sensors and as energy harvesters but are normally much less effective at high temperatures, limiting their use in environments such as engines or space exploration. However, a ...

On the dot: Novel quantum sensor provides new approach to early diagnosis via imaging

Oxygen is essential for human life, but within the body, certain biological environmental conditions can transform oxygen into aggressively reactive molecules called reactive oxygen species (ROS), which can damage DNA, RNA, ...

Venus flytraps found to produce magnetic fields

The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the closure of the leaf lobes. ...

Zapping quantum materials with lasers tells us how atoms relate

Phase transitions are a fundamental piece of physics and chemistry. We're all familiar with different phases of water, for example, but this idea of a system of particles changing what it looks like and how it behaves is ...
