β-Resin was extracted by solvent separation of refined coal tar pitch. Several analytical methods revealed that β-resin had a better aromatic plane packing structure and a higher number of carbon residues, making it ideal for mesophase transformation. The mesophase transformation process of β-resin (the formation of liquid-crystalline spheres, the growth of mesophase spheres, and the coalescence and disintegration of mesophase spheres) was observed in situ using a polarizing microscope with a hot stage. Moreover, the mesophase transformation mechanism of β-resin was investigated at each transformation stage. The mesophase content and mesophase transformation kinetics were analyzed based on the area method and quinoline insoluble (QI) substitution method. Both methods revealed changes in the mesophase content of β-resin. However, the test results of the two methods were slightly different at the initial stage of mesophase transformation and tended to be consistent during the later stage.

Carbonaceous materials are considered as potential adsorbents for organic dyes due to their unique structures which provide high aspect ratios, hydrophobic property, large efficient surface area, and easy surface modification. In this work, graphene nanoribbons (GNRs) were prepared by atomic hydrogen-induced treatment of single-walled carbon nanotube (SWCNTs), which inspire the idea of cutting and unzipping the SWCNTs carpets with the modified in molecules prevent because of the unfolding of the side-walls. The unfolded spaces and uniform vertical arrangement not only enhance the active surface area, but also promote the electrostatic and π–π interactions between dyes and GNRs. The improved adsorption capacity of GNRs beyond original SWCNTs can be determined by the adsorption kinetics and isotherm, which are evaluated through adsorption batch experiments of the typical cationic methylene blue (MB) and anionic orange II (OII) dye, respectively. It is shown that the adsorption kinetics follow a pseudo second-order model while the adsorption isotherm could be determined by Langmuir model. The results reveal that the maximum adsorption capacities of GNRs for MB and OII are 280 and 265 mg/g, respectively. The GNRs present the highly efficient, cost effective, and environmental friendly properties for the commercial applications of wastewater treatment.

The relationship of parasocial Interaction is one of the important contents of marketing research in recent years. With the rise of internet economy in the world, more and more enterprises' marketing practices are involved in the marketing process of SNS based on social networks. The interaction between medium and audiences has broken through the non-face-to-face one-way communication mode and forms a twoway communication mode of the relationship of parasocial Interaction in the SNS environment. Based on the signaling theory and the social exchange theory, this dissertation clarifies the driving factors and mechanism between Fashion web celebrity and attributes and relationship of parasocial interaction through the literature review, In the South China, Middle and North China, there were N audiences who used SNS experience as survey target to conduct a survey. And analyzed these data with SEM software. The research found that between Fashion web Fashion web celebrity and attributes and SNS participation motivation show a positive correlation with relationship of parasocial interaction, and there is a positive correlation between relationship of parasocial interaction and identification, relationship of parasocial interaction and identification have positive correlation with customer equity. E-WOM on customer asset-driven process has a clear intermediary role in the relationship of parasocial Interaction. This not only enriches and develops the existing research results of relationship of parasocial Interaction, but also provides guidance for enterprises to manage relationship of parasocial interactions. In addition, it also provides valuable theoretical guidance for enterprises to promote SNS marketing management practices.
