Until very recently, 'handedness' in large area films with atomic scale precision hadn't been investigated. A research team now has broken new ground in this area, developing a chiral atomically thin film only 2-atoms-thick, through circular stacking of graphene.
Researchers have succeeded in using the immensely powerful x-ray pulses from the free electron laser (XFEL) facility SACLA to investigate excited-state induced transient lattice dynamics on sub-picosecond time scales in phase-change materials via x-ray diffraction.
When remote regions with limited health facilities experience an epidemic, they need portable diagnostic equipment that functions outside the hospital. As demand for such equipment grows, researchers have developed a low-cost and portable microfluidic diagnostic device. It has been tested on Ebola and can be used to detect many other diseases.
If topological insulators are doped with impurities that possess magnetic properties, they lose their conductivity. Yet contrary to what has been assumed thus far, it is not the magnetism that leads to this.
