The transition to net zero emissions requires the capture of carbon dioxide from industrial point sources, and direct air capture (DAC) from the atmosphere for geological storage. Dissolved CO has reactivity to rock core, and while the majority of previous studies have concentrated on reservoir rock or cap-rock reactivity, the underlying seal formation may also react with CO. Drill core from the underlying seal of a target CO storage site was reacted at in situ conditions with pure CO, and compared with an impure CO stream with SO, NO and O that could be expected from hard to abate industries.

- Carbon dioxide geological storage aims to reduce net zero emissions but poses environmental risks, particularly the mobilization of heavy metals if CO migrates.
- Previous research has primarily examined pure CO, whereas this study tested sandstone and mudstone samples with both pure CO and an impure NO-SO-CO stream, revealing various metal reactions.
- The experiments demonstrated that impure CO reactions led to higher metal release due to lower pH and oxidizing conditions, emphasizing the need for further investigation into gas mixtures that may be used in carbon storage processes.
Objectives: 1) To quantify hospital-level variation in use of neuroimaging to screen for intracranial injury (ICI) among infants without overt signs or symptoms of head trauma undergoing subspecialty evaluations for physical abuse; 2) to assess for disproportionality in neuroimaging based on race and ethnicity and insurance type.
Methods: This was a cross-sectional study of infants age <12 months receiving subspecialty child abuse evaluations from February 2021 to December 2022 at 10 sites in CAPNET, a multicenter child abuse research network. Infants were included if they underwent a skeletal survey and lacked overt signs of possible ICI or blunt head injury.
Background: Skeletal surveys (SS) are recommended for the evaluation of suspected physical abuse in children <2 years old. No guidelines exist for SS completion in children between 2 and 5 years old.
Objective: To determine rates of SS completion by age and examine variables associated with occult fracture identification in older children.
Background: International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes have been shown to underestimate physical abuse prevalence. Machine learning models are capable of efficiently processing a wide variety of data and may provide better estimates of abuse.
Objective: To achieve proof of concept applying machine learning to identify codes associated with abuse.
