Unsaturated edge-anchored Ni single atoms on porous microwave exfoliated graphene oxide for electrochemical CO2

Abstract: Supported single atom catalysts (SACs), emerging as a new class of catalytic materials, have been attracting increasing interests. Here we developed a Ni SAC on microwave exfoliated graphene oxide (Ni-N-MEGO) to achieve single atom loading of ∼6.9 wt%, significantly higher than previously reported SACs. The atomically dispersed Ni atoms, stabilized by coordination with nitrogen, were found to be predominantly anchored along the edges of nanopores (

Low mindfulness predicts pain catastrophizing in a fear-avoidance model of chronic pain

Abstract: The relationship between persistent pain and self-directed, non-reactive awareness of present-moment experience (i.e., mindfulness) was explored in one of the dominant psychological theories of chronic pain - the fear-avoidance model[53]. A heterogeneous sample of 104 chronic pain outpatients at a multidisciplinary pain clinic in Australia completed psychometrically sound self-report measures of major variables in this model: Pain intensity, negative affect, pain catastrophizing, pain-related fear, pain hypervigilance, and functional disability. Two measures of mindfulness were also used, the Mindful Attention Awareness Scale [4] and the Five-Factor Mindfulness Questionnaire [1]. Results showed that mindfulness significantly negatively predicts each of these variables, accounting for 17-41% of their variance. Hierarchical multiple regression analysis showed that mindfulness uniquely predicts pain catastrophizing when other variables are controlled, and moderates the relationship between pain intensity and pain catastrophizing. This is the first clear evidence substantiating the strong link between mindfulness and pain catastrophizing, and suggests mindfulness might be added to the fear-avoidance model. Implications for the clinical use of mindfulness in screening and intervention are discussed.

N-Doped Graphene from Metal–Organic Frameworks for Catalytic Oxidation of p-Hydroxylbenzoic Acid: N-Functionality and Mechanism

Abstract: N-doped graphene has been considered as a promising catalyst with surface metal-free active sites for environmental remediation. Several MIL-100 (Fe)-templated N-doped graphene samples were synthesized using dicyandiamide, melamine, and urea as the nitrogen precursors. Excellent catalytic oxidation of p-hydroxylbenzoic acid (PHBA) was observed on the as-synthesized samples via peroxymonosulfate (PMS) activation. The mechanism was investigated by both electron paramagnetic resonance (EPR, 5,5-dimethyl-1-pyrroline N-oxide and 2,2,6,6-tetramethyl-4-piperidinol as the trapping agents) and quenching tests (ethanol and sodium azide as the radical scavengers). Benzoic acid and furfuryl alcohol were also employed as probing reagents for hydroxyl/sulfate radicals and singlet oxygen, respectively. The results confirmed that singlet oxygen was generated and dominated the PHBA degradation on N-doped graphene, rather than hydroxyl/sulfate radicals. With the novel N-doped graphene, this study illustrates the formation ...
