The setup of Hui Zhao and his team at the University of Kansas Ultra Fast Laser Laboratory.A team of researchers from the University of Kansas's ultrafast laser laboratory recently managed to capture real-time ballistic transmission of electrons in graphene, which could lead to faster, more powerful, and more energy-efficient electronic devices in the future.The motion of electrons is of...

Detecting the presence of nanoscale plastic particles in the environment has become a topic of concern for industrial societies worldwide, not least since particles of that size can evade the body's blood-brain barrier and damage metabolic processes.Optical technologies have been at the forefront of these monitoring efforts. Recent examples have included the use of stimulated Raman scattering to s...

From May 15 to 17, 2025, the 20th Wuhan Optoelectronics Expo will be held grandly at the China Optics Valley Convention and Exhibition Center in Wuhan. With the theme "Light Connects Everything, Intelligence Leads the Future," this year's expo will focus on six major fields: laser technology and applications, optics and precision optics, information communication and semiconductors, automotive opt...

Scientists at the City University of New York use tiny nitrogen defects in the atomic structure of diamonds as "color centers" to write data for storage. This technology is published in the journal Nature Nanotechnology and allows for encoding multiple bytes of data into the same nitrogen defect at multiple optical frequencies, without confusing the information content.The common laser based techn...

Two dimensional transition metal chalcogenides have multi valley structures in their energy bands, giving them electron valley degrees of freedom, making them an ideal platform for studying multi body interactions. As the main mechanism of valley depolarization, the valley scattering process of free electrons or bound excitons is crucial for exploring excited state electron phonon interactions and...
