Abstract: Understanding the abundance of atomic oxygen in the vicinity of carbon surfaces exposed to high-enthalpy flows is critical to accurate predictions of the gas–surface interaction. A novel approach for obtaining absolute number density measurements of atomic oxygen in high-enthalpy facilities with nanosecond laser pulses is described and demonstrated using photoionization-dominated, two-photon laser-induced fluorescence. In two-photon laser-induced fluorescence measurements, the depopulation of the excited state is typically dominated by electronic quenching, which depends on the temperature, pressure, and gas composition. To account for the electronic quenching rate, the fluorescence lifetime can be measured by temporally resolving the fluorescence. This can prove challenging in high-temperature and/or high-pressure environments where the fluorescence lifetime can be less than a nanosecond. Instead, by increasing the laser intensity until photoionization dominates the depopulation of the excited state, we create a quenching-independent measurement that is proportional to absolute number density. This technique is demonstrated here in the reacting boundary layer of a graphite sample ablating in the 6000 K plume of an inductively coupled plasma torch. The boundary layer possesses a large temperature gradient that varies from about 2000 K near the sample surface to the plume temperature of 6000 K in a span of approximately 2 mm. The photoionization-dominated technique is calibrated by using the freestream oxygen concentration, assuming the torch plume is in local thermodynamic equilibrium. The spatial resolution of the measurements is 50 µm and we are able to measure the number density of atomic oxygen to within about 60 µm of the graphite sample.

Time-Dependent Structure Assessment of Conjugated Polymer Aggregates in Solution by Single-Molecule Fluorescence Spectroscopy Monitoring and understanding the aggregation kinetics of n-type polymers provide strategies to favorably control aggregation and thereby optimize conjugated polymers ink shelf life, printability, and thin-film properties. Here, the in situ characterization of n-type copolymer aggregates employing ensemble absorbance and fluorescence spectroscopy for spectral characterization, in combination with single-molecule fluorescence spectroscopy methods to identify subcategories of aggregates, is reported. Specifically, we utilize a diffusion-based single-molecule burst method that resolves individual aggregates as they traverse the observation volume, allowing us to determine the aggregate size, concentration, and chain conformation through the statistical analysis of single-aggregate fluorescence data. Base-stable P(EO-NDIT2) with branched ether-based side chains self-assembles from molecularly dissolved chains into nano- to micrometer-sized aggregates over the course of weeks to months, depending on the solvent used. Through spectral decomposition and polarization-sensitive single-molecule fluorescence spectroscopy, the aggregates were categorized by their size into small (Rh approximately 60 nm) and large (Rh approximately 300 nm) aggregates and monitored with time. An increase in size was correlated with enhanced fluorescence brightness and red-shifted emission as well as an increase in internal order, as revealed by emission anisotropy. This increase in order within the aggregates may be related to alignment of crystalline domains and a planarization of the polymer backbone torsion.

New publication in ACS Macromolecules highlighting extraordinary long time aggregation processes over months in conjugated polymers.
