Quality Control Measures for Enhancing Confidence in Nanoscale IR Spectroscopy

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Common lab materials and sample handling may introduce molecular and particulate contaminants detectable by PiFM. We present a spectral database of common contaminant signatures to support accurate nanoscale analysis. We provide practical guidelines to improve preparation, handling, and storage of samples to mitigate contamination, ensuring ...

Aquitardifer: A New Hydrogeologic Term for Geologic Materials with both Aquitard and Aquifer Properties

open access: yesGroundwater, EarlyView.
Abstract We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.

How Binding Is Administrative Guidance? An Empirical Study of Guidance, Rules, and the Courts Telling Them Apart

open access: yesJournal of Empirical Legal Studies, EarlyView.
ABSTRACT Guidance documents are a main pillar of the modern administrative state. While federal agencies issue thousands of rules every year through notice‐and‐comment rulemaking, they issue even more guidance documents in various forms. There is, however, an ongoing and fierce dispute over agencies' ability to create binding obligations through ...
