1. Oblique drop impact: can one infer the angle of impact?

   During solid surface impact, a falling drop's energy is transformed into oscillations of its liquid/gas interface. We consider drop deposition during oblique impact in the capillary-ballistic regime characterized by high Reynolds number and moderate Weber number. We treat this as an inverse problem showing that post-impact observations of the frequency spectrum and modal partition of energy allow one to determine a drop's pre-impact characteristics and wetting properties. Our analysis is useful for quantifying contact-line dissipation during inertial spreading and can be used as a diagnostic technique for determining substrate wetting properties.

2. Quantifying the Impact of IDPs

   To address the need for more structured, diverse, inclusive, equitable, holistic, and ongoing career planning, Individual Development Plans (IDPs) are used widely by academic institutions. Although IDPs have an enormous capacity to contribute to a wide scope of student outcomes including equitable training, mentorship, wellness, and career planning, assessment is complicated by the different IDP ideologies, frameworks, and tools that exist, as well as the different ways IDP creation process is facilitated. The goal of the NSF-funded Impact Indicators and Instruments for Individual Development Plans (I3IDP) project is to develop instruments to measure the outcomes and impact of IDPs on the development of graduate students in STEM. The development of these assessment instruments will facilitate the generation of comparable data within and across institutions to enhance the understanding of best practices in IDP use for PhD career planning. Of particular note is how IDPs may help lower the career and training barriers that exist for diverse and underrepresented groups. Partners behind this NSF funded project include GCC and creators from well-known IDP tools (myIDP.org, ChemIDP.org, ImaginePhD). In this interactive session we will present the indicators and outcomes of the IDP process as determined from stakeholder interviews and literature review, give participants a preview of the survey instruments, and discuss how IDP intervention can be used to provide more equitable training to graduate students and postdocs across multiple identity differences and intersectionality.

4. Explosive interaction of impact melt and seawater following the Chicxulub impact event

   Abstract The impact of asteroids and comets with planetary surfaces is one of the most catastrophic, yet ubiquitous, geological processes in the solar system. The Chicxulub impact event, which has been linked to the Cretaceous-Paleogene (K-Pg) mass extinction marking the beginning of the Cenozoic Era, is arguably the most significant singular geological event in the past 100 million years of Earth’s history. The Chicxulub impact occurred in a marine setting. How quickly the seawater re-entered the newly formed basin after the impact, and its effects of it on the cratering process, remain debated. Here, we show that the explosive interaction of seawater with impact melt led to molten fuel–coolant interaction (MFCI), analogous to what occurs during phreatomagmatic volcanic eruptions. This process fractured and dispersed the melt, which was subsequently deposited subaqueously to form a series of well-sorted deposits. These deposits bear little resemblance to the products of impacts in a continental setting and are not accounted for in current classification schemes for impactites. The similarities between these Chicxulub deposits and the Onaping Formation at the Sudbury impact structure, Canada, are striking, and suggest that MFCI and the production of volcaniclastic-like deposits is to be expected for large impacts in shallow marine settings.
