As an alum I can testify that my education at Seattle Pacific University was lacking in a few areas. My political science courses were sparing on queer civil rights in the United States, and I cannot recall any real discussion of activism on college campuses as a force for change. Perhaps I dozed off in class once or twice. However, I’m proud to report that I’m now a bit more informed on these topics.

Asphaltenes are high-boiling and recalcitrant compounds that are generally minor components of crude oil (∼0.1–15.0 wt %) but dominate the composition of heavily weathered spilled petroleum. These solid residues exhibit a high structural complexity, comprised of polycyclic aromatic hydrocarbons (PAHs) that are a mixture of single-core (island) and multicore (archipelago) structural motifs. The mass fraction of each motif is sample-dependent.
