Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ultra-thin two-dimensional (2D) materials can act as stable quantum systems ...
Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...
Scientists developed a two-photon-enhanced metasurface that cuts photon requirements for nanoscale displacement measurement ...
Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...
Human cells are extremely small and tightly packed – at about 20 micrometers across, ...
