Involvement of the organics in aqueous phase of bio-oil in hydrothermal carbonization of lignin.

Aqueous phase of bio-oil (APBO) is water-rich but also contains some sugar-derivatives and phenolics. APBO has little potential as feedstock for producing biofuel, but can be potentially used as medium for hydrothermal carbonization (HTC) of biomass. In this study, the HTC of lignin in APBO was conducted, aiming to probe the influence of the organics in APBO on property of the hydrochar. The results indicated that the organics in APBO cross-polymerized with lignin derivatives, resulted in the yield of hydrochar to exceed 100%. In addition, APBO promotes the deoxygenation but does not promote dehydrogenation. More aliphatic structures are generated in the hydrochar, reducing its thermal stability. In addition, the hydrochar from APBO also shows the improved combustion performance by lowering the activation energy and the ignition temperature (180 vs 240 °C).

The relationship between mindfulness and envy: The mediating role of emotional intelligence.

Envy is a mixed negative emotion that is characterized by feelings of hostility, inferiority, resentment, and depression. It has been found that mindfulness is negatively associated with envy. This paper aimed to explore the interaction between mindfulness and envy by referring to the mindful emotion regulation model, and it also examines the mediation of emotional intelligence. Six hundred and seventy-six participants (182 men and 494 women) completed the Mindful Attention Awareness Scale, the Dispositional Envy Scale, and the Wong Law Emotional Intelligence Scale. Results suggest that mindfulness is significantly and negatively correlated with envy. Meanwhile, a multiple mediation analysis indicated that regulation of emotion and use of emotion partially mediate the impact of mindfulness on envy. The current study not only provides a theoretical basis for possible mechanisms underlying the inhibition of envy, but also provides valuable guidance for developing mindfulness-based intervention programs aiming at reducing the negative effects of envy.

Hydrogen-bonded frameworks crystals-assisted synthesis of flower-like carbon materials with penetrable meso/macropores from heavy fraction of bio-oil for Zn-ion hybrid supercapacitors.

The application of biomass-based carbon materials in electrode materials are usually subject to their deficient adsorption sites as well as sluggish diffusion of electrolyte ions. Herein, flower-like carbons are obtained from the heavy fraction of bio-oil with the auxiliary of Hydrogen-bonded frameworks (HOFs) crystals. During the co-carbonization of the both, the HOFs crystals are removed on account of its poor stability, which directs the formation of flower-like morphology and generates the penetrable meso/macropores across petal-like carbon nanosheets. In addition, the pyrolysis gases serve as the agents for activation to enrich the active sites without the further activation. The degree of graphitization and the contents of pyridine nitrogen for carbon materials could be flexibly adjusted with the contents of HOFs. Owing to the beneficial 3D flower-like structure, high specific surface area (1076 m2/g), large pore volume (2.59 cm3/g), and rational N species, the assembled Zn//BH-4 hybrid supercapacitor reaches a superior energy density of 117.5 Wh/kg at 890 W/kg and maintains 60.7 Wh/kg even at 16.2 kW/kg.

How mindfulness affects benign and malicious envy from the perspective of the mindfulness reperceiving model.

At present, mindfulness is a hotspot in psychological research. Mindfulness is an effective tool that enables people to effectively inhibit negative emotions. Previous studies have shown that envy is a typical negative emotion; however, envy can be divided into two completely different types: benign envy and malicious envy. The question then arises, how does mindfulness affect both types of envy? Using a mindfulness reperceiving model, we explored the effect of mindfulness on these two different types of envy and on the mediating mechanism of psychological resilience. To accomplish this, we recruited 676 Chinese undergraduates to complete the Mindful Attention Awareness Scale (MAAS), the Benign and Malicious Envy Scale (BEMAS) and the Connor-Davidson Resilience Scale (CD-RISC). The results we obtained showed that mindfulness and psychological resilience significantly and negatively predicted malicious envy and that psychological resilience played a partially mediating role in the relationship. In addition, the results showed that there was no significant effect between mindfulness and benign envy; however, psychological resilience can significantly and positively predict benign envy and played a completely mediating role between mindfulness and benign envy. These results effectively extend theories based on the mindfulness reperceiving model while also being important for promoting benign envy and inhibiting malicious envy in terms of improving mindfulness and psychological resilience.
