Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar ...

(Nanowerk News) H2+ was one of the first molecules to form after the Big Bang. It consists of the most fundamental components that were formed very early on in the universe: two hydrogen nuclei (the ...

Using SLAC's high-speed 'electron camera,' scientists simultaneously captured the movements of electrons and nuclei in a light-excited molecule. This marks the first time this has been done with ...

Single-molecule fluorescence detection (SMFD) is able to probe, one molecule at a time, dynamical processes that are crucial for understanding functional mechanisms in biosystems. Fluorescence in the ...

The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in our atmosphere that can lead to smog and pollution. However, changes in ...

Scientists from Germany, Japan, and India have demonstrated that femtosecond laser pulses can force an entire layer of molecules to rotate in unison on a two-dimensional quantum material, a result ...

Figure 1. Basic structure and working mechanism of SM-SERS substrate. a) Schematic diagram of rapid SM-SERS signal formation. b) SEM image of SM-SERS substrate. c) Optical image of sample under ...

“UV light can be dangerous if you want to apply it in any biological system,” Feringa says, because the high-energy light can initiate photochemical reactions that damage biological molecules. For a ...

The simplest possible molecule H 2 + was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental ...
