New strategy uses ionic liquids to change laser colors with ease

Lasers are intense beams of colored light. Depending on their color and other properties, they can scan your groceries, cut through metal, eradicate tumors, and even trigger nuclear fusion. But not every laser color is available ...

CO molecular tilting detected by red-shifted TERS

The invention of scanning probe microscopy (SPM) techniques, including scanning tunneling microscopy (STM) and atomic force microscopy (AFM), has led to a paradigm shift in the visualization and understanding of surface structures ...

Powerful impact provides insight into deep structure of Mars

NASA's InSight lander (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) launched in 2018 with the goal of peering deep into Mars's interior for the first time to gain important information about ...

Internet cable reveals the source of underwater vibrations

Scientists have harnessed Internet-transmitting fiber-optic cables to overcome a long-standing geophysical challenge: identifying where seismic noise in the ocean originates. Tiny vibrations of Earth called microseisms are ...

Physicists make molecular vibrations more detectable

In molecules, the atoms vibrate with characteristic patterns and frequencies. Vibrations are therefore an important tool for studying molecules and molecular processes such as chemical reactions. Although scanning tunneling ...
