String theory offers a viable theory of quantum gravity, with spin 2 gravitons encoded in closed strings.&nbs

The dynamics of photoexcited solute molecules and the properties of liquid interfaces are studied by carrying out spectroscopy and scattering experiments on flat liquid water jets. In one set of experiments, solute dynamics are probed using time-resolved photoelectron spectroscopy in which molecules are photoexcited with a femtosecond UV pulse and photoionized with a time-delayed femtosecond XUV pulse (at 21.7 eV). The time-dependent photoelectron spectra provide a unique probe of the relaxation of photoexcited neutral and anionic species in aqueous solution.

I will discuss NASA's Lucy mission, which is the first reconnaissance of the Jupiter Trojan asteroids. Asteroids are the leftovers from the age of planet formation. But, unlike the planets themselves, they have remained relatively unchanged since they formed. As a result, they hold vital clues to how our Solar System formed and evolved, and thus can be considered the fossils of planet formation. Lucy will visit eight of these important objects between 2027 and 2033.

All chemical reactions are controlled by species we rarely detect: short-lived carbenes, radicals, and ketenes steer reaction pathways and ultimately determine selectivity and yield. Conventional tools such as GC/MS or NMR usually miss intermediates, even though mechanistic insight is urgently needed for rational process optimization.
