Faculty, Staff and Students Publications

Identifying tertiary structures and protein binding sites in RNA molecules remains a key challenge in RNA biology. We describe multi-site dimethyl sulfate (DMS)-mutational profiling (MaP) (msDMS-MaP), a strategy that enables simultaneous measurement of RNA secondary, tertiary, and quaternary structures via a single DMS chemical probing experiment. Optimized reverse transcription decodes typically invisible DMS N7-methylguanine (N7-G) modifications via a tautomer-induced mutational signature concurrent with N1 and N3 modifications. We show that N7-G reactivity reports on higher-order RNA structures, revealing key functional motifs such as pseudoknots and protein binding sites. Using msDMS-MaP, we find that E. coli ribosomal RNAs encode numerous independently …

Methods To Enhance Groundwater Remediation During Cbr And Mass Transfer Controls On Post-Closure Groundwater Cleanup At Ccr Impoundments, Sean Larkin, Jacob Chu, John Blue

World of Coal Ash Proceedings

Utilities are implementing closure‑by‑removal (CBR) of coal combustion residual (CCR) impoundments as part of corrective action programs to meet groundwater protection standards (GWPSs) and are evaluating closure strategies for Legacy Units. Although CBR and associated decanting and dewatering systems can substantially reduce source mass and improve groundwater quality, lingering “tail” concentrations in the aquifer are often observed after closure because groundwater remediation typically requires extended timeframes. These persistent concentrations may be compounded by secondary source zones beneath the former impoundment, where constituent mass stored in low‑permeability materials or immobile pore spaces is slowly released into the transmissive aquifer after CBR. …

Increase Drying Rate And Reduce Heavy Metals In Legacy Coal Ash Landfills With Biochar Addition, David Schmidt

World of Coal Ash Proceedings

A northern US power plant is preparing for the closure of 40-year-old coal ash and wet FGD (flue gas desulfurization) ponds per CFR 257.102. The pond’s contents must be dried before capping to allow heavy machinery to operate on the surface to spread the cover and liner materials. However, the high moisture content (55%) and the water holding capacity of the pond mixture, combined with a wet, cold climate, are preventing adequate drying to achieve the mandated closure dates. The US Forest Service funded this project to determine whether biochar made from waste wood can aid in ash pond remediation. …
