Brand engagement on social media: will firms’ social media efforts influence search engine advertising effectiveness?

Abstract: Although firms leverage social media platforms such as Facebook to engage with customers, they often treat social media elements and other online marketing activities such as search engine advertising as stand-alone, rather than part of an integrated online activities system. Hence, it is important to systematically understand how specific elements of social media, signifying and representing behavioural manifestations of brand engagement, relate to other online activities. We study how three types of brand engagement on social media – affiliation, conversation and responsiveness – influence search engine advertising effectiveness, including click-through rate and conversion rate. Specifically, we find that affiliation, conversation and responsiveness increase click-through rate and conversion rate. Moreover, brand engagement on social media strengthens the relationships between advertisement rank and search engine advertising effectiveness.

Synthesis of mesoporous magnetic Fe3O4@carbon nanofibers utilizing in situ polymerized polybenzoxazine for water purification

Abstract: A novel and scalable strategy was developed for the synthesis of one dimensional mesoporous polybenzoxazine-based Fe3O4@carbon nanofibers by using an in situpolymerization method, which exhibit an extremely high surface area of 1885 m2 g−1, as well as efficient adsorption for organic dyes and facilely magnetic separation property.

Palladium/Graphitic Carbon Nitride (g‐C3N4) Stabilized Emulsion Microreactor as a Store for Hydrogen from Ammonia Borane for Use in Alkene Hydrogenation

Abstract: Direct hydrogenation of C=C double bonds is a basic transformation in organic chemistry which is vanishing from simple practice because of the need for pressurized hydrogen. Ammonia borane (AB) has emerged as a hydrogen source through its safety and high hydrogen content. However, in conventional systems the hydrogen liberated from the high‐cost AB cannot be fully utilized. Herein, we develop a novel Pd/g‐C3N4 stabilized Pickering emulsion microreactor, in which alkenes are hydrogenated in the oil phase with hydrogen originating from AB in the water phase, catalysed by the Pd nanoparticles at the interfaces. This approach is advantageous for more economical hydrogen utilization over conventional systems. The emulsion microreactor can be applied to a range of alkene substrates, with the conversion rates achieving >95 % by a simple modification.
