May 12, 2025 The universe is decaying much faster than thought. This is shown by calculations of three Dutch scientists on the so-called Hawking radiation. (Nanowerk News) The research by black hole expert Heino Falcke, quantum physicist Michael Wondrak, and mathematician Walter van Suijlekom (all from Radboud University, Nijmegen, the...
Measuring molecular orientation in nanoscale gaps using enhanced vibrational spectroscopy
May 12, 2025 A nanoscale spectroscopy technique reveals the orientation of surface-bound molecules with sub-nanometer precision by confining light in a near-field region between a scanning probe and substrate. (Nanowerk News) Vibrational sum-frequency generation (VSFG) spectroscopy is a nonlinear optical method widely used to study how molecules are arranged and...
