Resonance Raman scattering provides new ways for high-sensitivity temperature probing

2 is experiencing resonance Raman scattering under 532 nm laser excitation, its two Raman peaks (A1g and E2g) have different variation behaviors against temperature, while their ratio (Ω=IA1g / IE2g) shows universal behavior regardless of the sample structure (thickness, suspended or supported). This ratio changes by more than 100-fold from 177 K to 477 K, … Read more

Probing the Red Planet: Finding past life at Jezero Crater

Since its wheels-down landing in February of last year, NASA’s Perseverance Mars rover has been busily at work, on the prowl steering itself across the Jezero Crater landscape. A key duty of the robot is to search for signs of ancient microbial life. The Mars is industriously machinery gathering up samples of Martian rock and … Read more

Magnetic quantum material broadens platform for probing next-gen information technologies

Neutron scattering revealed spin correlations of iron trichloride. An artist’s depiction interprets the scattering that provides evidence of a spiral spin liquid state. Credit: Jacquelyn DeMink/ORNL Scientists at the Oak Ridge National Laboratory used neutron scattering to determine whether a specific material’s atomic structure could host a novel state of matter called a spiral spin … Read more
