D-Map: Visual analysis of ego-centric information diffusion patterns in social media

Abstract: Popular social media platforms could rapidly propagate vital information over social networks among a significant number of people. In this work we present D-Map (Diffusion Map), a novel visualization method to support exploration and analysis of social behaviors during such information diffusion and propagation on typical social media through a map metaphor. In D-Map, users who participated in reposting (i.e., resending a message initially posted by others) one central user's posts (i.e., a series of original tweets) are collected and mapped to a hexagonal grid based on their behavior similarities and in chronological order of the repostings. With additional interaction and linking, D-Map is capable of providing visual portraits of the influential users and describing their social behaviors. A comprehensive visual analysis system is developed to support interactive exploration with D-Map. We evaluate our work with real world social media data and find interesting patterns among users. Key players, important information diffusion paths, and interactions among social communities can be identified.

Polyelectrolytes self-assembly: versatile membrane fabrication strategy

Abstract: Polyelectrolytes self-assembly is developing rapidly as a fascinating family of functional membrane fabrication strategies with the ability to modulate the architectures and physical–chemical characteristics of membranes at the molecular level. Research on polyelectrolytes self-assembly is motivated by the flexible choice of functional groups and processing technologies as well as the synergy of the charge and nanostructure control, thus allowing extensive applications of polyelectrolytes-based functional membranes for precise separation. Herein, an account of recent advances in the design and performance evaluation of polyelectrolytes self-assembled membranes is provided. First, the rational selection of polyelectrolytes is outlined, with a focus on selection criteria and structure–performance relationship, which are crucial factors for membrane fabrication. Then, the different design strategies of polyelectrolytes self-assembled membranes are introduced, comprising well-established and newly emerging methods. Next, the separation-related applications so far pursued by polyelectrolytes self-assembled membranes are itemized, covering gas separation and liquid separation. Their potential utility targeting on challenging separation fields such as decontamination, organic micropollutants removal, and resources recovery, is emphatically highlighted. Looking forward, exploiting the high flexibility and feasibility of certain polyelectrolytes self-assembly techniques is put into perspective for niche applications that are not easily achievable by other polymers. Overall, critical insights are provided for the materials science and membrane communities to navigate better exploring the potential of polyelectrolytes self-assembly for developing advanced functional membranes.
