Molecular diffusion and self-assembly: Quantifying the influence of substrate hcp and fcc atomic stacking
No full textMolecular diffusion is a fundamental process underpinning surface-confined molecular self-assembly and synthesis. Substrate topography influences molecular assembly, alignment, and reactions; with the relationship between topography and diffusion linked to the thermodynamic evolution of such processes. Here, we observe preferential adsorption sites for tetraphenylporphyrin (2H-TPP) on Au(111) and interpret nucleation and growth of molecular islands at these sites in terms of spatial variation in diffusion barrier; driven by local atomic arrangements of the Au(111) surface (the 22 X sqrt{3} `herringbone' reconstruction). Variable-temperature scanning tunnelling microscopy facilitates characterisation of molecular diffusion, and Arrhenius analysis allows quantitative characterisation of diffusion barriers within fcc and hcp regions of the surface reconstruction (where the in-plane arrangement of the surface atoms is identical, but the vertical stacking differs). The higher barrier for diffusion within fcc locations underpins the ubiquitous observation of preferential island growth within fcc regions, demonstrating the relationship between substrate-structure, diffusion, and molecular self-assembly

Full Forcing Weather File
No full textMeteorological data from the weather station, recorded at 30-minute intervals, were used to generate the full forcing weather file for the simulations. Measurements of temperature, humidity, global radiation, and precipitation were taken at 4 meters above ground level, while wind speed and direction were measured at 10 meters. Data covering a total of 20 days — from 23 August to 2 September 2022, and from 26 December 2022 to 5 January 2023 — were used

No full textEffectiveness and acceptability of an online trauma stabilisation group in a secondary mental health setting
No full textTrauma informed care continues to be promoted in healthcare policies, with psychoeducation groups providing a time-efficient intervention towards this aim. Although evidence for the effectiveness of trauma psychoeducation groups is mixed, they are considered an important facet of the first phase of trauma treatment. This study evaluated an online trauma stabilisation group piloted in a secondary mental health service. Nineteen participants referred for trauma therapy attended a nine-week intervention that aimed to increase understanding of trauma responses and strategies to manage responses. No significant differences were found in pre- and post-intervention scores, with negligible effect sizes. Reliable change was demonstrated in a small number of participants. The intervention was largely acceptable to participants. Recommendations are provided to increase the effectiveness and acceptability of the intervention
