The COVID-19 pandemic of 2020 raised concern for those spending time in college classrooms and dormitories. Students faced sudden changes to their lives and relied upon written messages for directives. This study investigated the language of university-based communications, based on models of crisis communication and epidemic management. The Linguistic Inquiry and Word Count was used to investigate the language in the most salient written messages from universities to students regarding the migration to online classes. As predicted,

Sufficient and well-distributed active sites and highly conductive carbon matrix are two important factors to achieve highly efficient electrocatalysts. In this study, we report an adjusted metal-organic frameworks (MOF)-based route for the preparation of nitrogen-doped Fe/Co bimetallic electrocatalysts. With suitable Fe/Co molar ratio (Fe/Co = 1/4.15), Co nanoparticles (NPs) with mild oxidation state and Co3Fe7 alloys wrapped with thin graphene layers are embedded in an integrated and continuous carbon network. The corresponding FC@NCs-4
