Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Electrical Breakdown Analysis of Emerging Oil–Paper Insulation Systems

High Voltage, EarlyView.
ABSTRACT This investigation addresses the effect of particulate additives on the electrical breakdown strength of the oil impregnated insulation paper system. The morphological complexity is addressed by converting data from scanning electron microscope images to a data set suitable for numerical simulation analysis. Then, by using the conventional oil‐

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

Acta Crystallographica Section B, EarlyView.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...

Mapping structure–property relationships in a 6‐oxo‐verdazyl radical by variable pressure crystallography and density functional theory

Acta Crystallographica Section B, EarlyView.
For the first time, the structural response to pressure of a verdazyl radical crystal has been studied. Computational modelling revealed changes in electronic and magnetic properties as a result of a structural phase transition.The response of the 1,5‐tolyl‐3‐phenyl‐6‐oxo‐verdazyl radical (pTolOV) to pressure in the crystalline state has been ...
