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.

This study examines the effects of esketamine on emotion processing and cognitive functioning, both acutely and sub-chronically.
Methods: Eighteen treatment-resistant depression (TRD) patients received repeated intravenous esketamine infusions.
The ever-growing interest in MXenes has been driven by their distinct electrical, thermal, mechanical, and optical properties. In this context, further revealing their physicochemical attributes remains the key frontier of MXene materials. Herein, we report the anisotropic localized surface plasmon resonance (LSPR) features in TiCT MXene as well as site-selective photocatalysis enabled by the photophysical anisotropy.

Of particular interest in ASD biomarker research is the study of visual attention, effectively quantified in eye tracking (ET) experiments. Eye tracking offers a powerful, safe, and feasible platform for gaining insights into attentional processes by measuring moment-by-moment gaze patterns in response to stimuli.

- 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.
