Influence of Cations on Direct CO Capture and Mineral Film Formation: The Role of KCl and MgCl at the Air/Electrolyte/Iron Interface.

Uncovering the mechanisms associated with CO capture through mineralization is vital for addressing rising CO levels. Iron in planetary soils, the mineral cycle, and atmospheric dust react with CO through complex surface chemistry. Here, the effect of cations on the growth of carbonate films on iron surfaces was investigated.

Investigating risk factors associated with pedestrian crash occurrence and injury severity in Texas.

Objective: This study investigates various risk factors associated with pedestrian crash occurrence and injury severity based on 78,497 reported pedestrian-involved crashes across Texas from 2010 through 2019.

Methods: Crashes are mapped to over 708,738 road segments, along with road design, land use, transit, hospital, rainfall, and other location features. Negative binomial models examine the association between pedestrian crash frequency and various contributing factors, and a heteroskedastic ordered probit model investigates the severity of injuries at the individual crash level.

Effect of Cations on the Oxidation and Atmospheric Corrosion of Iron Interfaces to Minerals.

Surface corrosion involves a series of redox reactions that are catalyzed by the presence of ions. On infrastructure surfaces and in complex and natural environments, iron surfaces readily undergo redox reactions, impacting chemical processes. In this study, the effect of how cations influence the formation of the mineral scale on iron surfaces and its connection to surface corrosion was investigated in CaCl(aq) and NaCl(aq) electrolytes.

PM-IRRAS at the Air/Electrolyte/Solid Interface Reveals Oxidation of Iron to Distinct Minerals.

Iron interfaces undergo redox and catalytic processes in various environments, on the surface of soils, dust, minerals, and materials that comprise industrial infrastructure. Measuring reactions at interfaces in complex environments is challenging, where adsorption of gases and interaction of aqueous species occur at the surface. This is due to the presence of several ionic species in solutions that catalyze surface oxidation and undergo ion exchange between the solution and the surface and from the influx of oxygen and other gases.

Neuroanatomic Correlates for the Neuropsychological Manifestations of Chiari Malformation Type I.

Chiari malformation comprises a spectrum of congenital malformations characterized by a herniation of the cerebellar tonsils below the foramen magnum. Chiari malformation type I (CM-I) is the most prevalent subtype seen in clinical practice. This condition variably compresses the cerebellum and medulla-spinal cord junction secondary to malformation of the posterior fossa.
