Anyone who has ever operated an infrared remote control to switch on a TV or open a garage door knows intuitively that light can activate a response from a device. But imagine if instead of triggering ...

Optical technique enables the study of very fast molecular rearrangements. The rearrangement of molecules during chemical reactions is so rapid—ranging from ten femtoseconds to one picoseconds—that ...

An international research team has succeeded in controlling the chirality of individual molecules through structural isomerization. The team also succeeded in synthesizing highly reactive diradicals ...

The three exposed tyrosines of RNase A have been converted to nitrotyrosines by reaction with tetranitromethane, and the changes in the ionization properties of these nitrotyrosines have been used to ...

Many natural and synthetic chemical systems react and change their properties in the presence of certain kinds of light. These reactions can occur too quickly for ordinary instruments to see. For the ...

A visible-pump/UV-probe transient absorption is used to characterize the ultrafast dynamics of bacteriorhodopsin with 80-fs time resolution. We identify three spectral components in the 265-to 310-nm ...

Curved molecules that absorb sunlight, store the energy, and re-release it as heat are pushing the boundaries in solar thermal storage technology. Subscribe to our newsletter for the latest sci-tech ...
