We report on the effects of electron collision and indirect ionization processes photoemission spectra liquid water, specifically at photoexcitation kinetic energies well below 30 eV.
We present chemical kinetics measurements of the luminol oxidation chemiluminescence (CL) reaction at interface between two aqueous solutions, using liquid jet technology. Free-flowing microjets are a relatively recent development that have found their way into growing number applications in spectroscopy and dynamics. A variant thereof, called flat-jet, is obtained when cylindrical jets crossed, leading to chain planar leaf-shaped structures flowing liquid. here show first leaf this chain,...
C-I bond extension and fission following ultraviolet (UV, 262 nm) photoexcitation of 2- 3-iodothiophene is studied using ultrafast time-resolved extreme (XUV) ionization in conjunction with velocity map ion imaging. The photoexcited molecules eventual I atom products are probed by site-selective at the 4d edge intense XUV pulses, which induce multiple charges initially localized to iodine atom. At separations below critical distance for charge transfer (CT), can redistribute around molecule...
Control over colloidal nanocrystal morphology (size, size distribution, and shape) is important for tailoring the functionality of individual nanocrystals their ensemble behavior. Despite this, traditional methods to quantify are laborious. New developments in automated classification will accelerate these analyses but assessment machine learning models limited by human accuracy ground truth, causing even unsupervised have inherent bias. Herein, we introduce synthetic image rendering solve...
We investigate the orientation dependence of Enhanced Ionization (EI) during strong-field-driven nuclear motion in acetylene (C$_2$H$_2$). Here, we both initiate and probe molecular dynamics with intense 6-fs cross-polarized pulse pairs, separated by a variable delay. Following multiple ionization first pulse, undergoes simultaneous elongation carbon-carbon carbon-hydrogen bonds, enabling further second formation very highly charged state, [C$_2$H$_2]^{6+}$. At small inter-pulse delays...
