Quantum Materials Quest Could Benefit From Graphene That Buckles

Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.

SLAC’s upgraded X-ray laser facility produces first light

The LCLS-II upgrade project will increase the X-ray laser’s power by thousands of times, producing a million pulses per second compared to 120 per second today. Now, the first phase of the upgrade has come into operation, producing an X-ray beam for the first time using newly installed undulators. The full upgrade is due to be completed within the next two years.

Facemask Fabric Filtration Efficiency

Scientists have completed an important and timely study of cloth masks. The study examined the filtration efficiency of fabrics and focused on aerosol particles in a range of sizes relevant to viral transmission through respiratory exposures. The best-performing masks used hybrid designs that include high thread-count cotton and electrostatic layers such as silk or polyester chiffon.
