In Situ Detection of Active Edge Sites in Single-Layer MoS Catalysts
MoS2 nanoparticles are proven catalysts for processes such as
hydrodesulphurization and hydrogen evolution, but unravelling their
atomic-scale structure under catalytic working conditions has remained
significantly challenging. Ambient pressure X-ray Photoelectron Spectroscopy
(AP-XPS) allows us to follow in-situ the formation of the catalytically
relevant MoS2 edge sites in their active state. The XPS fingerprint is
described by independent contributions to the Mo3d core level spectrum whose
relative intensity is sensitive to the thermodynamic conditions. Density
Functional Theory (DFT) is used to model the triangular MoS2 particles on
Au(111) and identify the particular sulphidation state of the edge sites. A
consistent picture emerges in which the core level shifts for the edge Mo atoms
evolve counter-intuitively towards higher binding energies when the active
edges are reduced. The shift is explained by a surprising alteration in the
metallic character of the edge sites, which is a distinct spectroscopic
signature of the MoS2 edges under working conditions

Does size really matter? A multisite study assessing the latent structure of the proposed ICD-11 and DSM-5 diagnostic criteria for PTSD
Background: Researchers and clinicians within the field of trauma have to choose between different diagnostic descriptions of posttraumatic stress disorder (PTSD) in the DSM-5 and the proposed ICD-11. Several studies support different competing models of the PTSD structure according to both diagnostic systems; however, findings show that the choice of diagnostic systems can affect the estimated prevalence rates. Objectives: The present study aimed to investigate the potential impact of using a large (i.e. the DSM-5) compared to a small (i.e. the ICD-11) diagnostic description of PTSD. In other words, does the size of PTSD really matter? Methods: The aim was investigated by examining differences in diagnostic rates between the two diagnostic systems and independently examining the model fit of the competing DSM-5 and ICD-11 models of PTSD across three trauma samples: university students (NÂ =Â 4213), chronic pain patients (NÂ =Â 573), and military personnel (NÂ =Â 118). Results: Diagnostic rates of PTSD were significantly lower according to the proposed ICD-11 criteria in the university sample, but no significant differences were found for chronic pain patients and military personnel. The proposed ICD-11 three-factor model provided the best fit of the tested ICD-11 models across all samples, whereas the DSM-5 seven-factor Hybrid model provided the best fit in the university and pain samples, and the DSM-5 six-factor Anhedonia model provided the best fit in the military sample of the tested DSM-5 models. Conclusions: The advantages and disadvantages of using a broad or narrow set of symptoms for PTSD can be debated, however, this study demonstrated that choice of diagnostic system may influence the estimated PTSD rates both qualitatively and quantitatively. In the current described diagnostic criteria only the ICD-11 model can reflect the configuration of symptoms satisfactorily. Thus, size does matter when assessing PTSD
