Since the earliest demonstration of chirped-pulse amplification (CPA) and optical parametric chirped-pulse amplification (OPCPA), femtosecond lasers have been able to deliver ultrahigh peak powers up to ten-petawatt (PW), ...
There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...
Lanthanide (Ln3+)-doped upconversion (UC) nanocrystals (NCs) have attracted considerable interest due to their superior optical features. Unfortunately, the relatively low luminescence intensity is a major drawback that seriously ...
Edge states are an emerging concept in physics and have been explored as an efficient strategy to manipulate electrons, photons and phonons for next-generation hybrid electro-optomechanical circuits. Scientists have used ...
Many natural surfaces can rapidly shed water droplets due to their water-repellent functionality. In 1945, scientists Cassie and Baxter linked the water-repellent function of natural surfaces to their surface textures. The ...
Since the outbreak of COVID-19, there's been a worldwide shortage of face masks—particularly, the N95 ones worn by health care workers. Although these coverings provide the highest level of protection currently available, ...
Three-dimensional (3-D) nanoprinting of freeform optical waveguides also known as photonic wire bonding can efficiently couple between photonic chips to greatly simplify optical system assembly. The shape and trajectory of ...
The conversion and utilization of solar energy for chemical fuel production and environmental remediation through artificial photocatalysis have been recognized to be an ideal route to address the critical energy and environmental ...
Modern applications use self-cleaning strategies and digital microfluids to control individual droplets of fluids on flat surfaces but existing techniques are limited by the side-effects of high electric fields and high temperatures. ...
Identifying a patient's viral infection or diagnosing a blood disorder usually requires a lab and skilled technicians. But researchers at Princeton University have developed a new technology that goes a long way toward replacing ...
