In this study, the 4-sulfobenzoic acid potassium salt is postsynthetically immobilized on the hexa-zirconium nodes of a zirconium-based MOF, MOF-808, by the solution-phase solvent-assisted ligand incorporation approach. With all of the sulfonate-based anions firmly immobilized within the rigid framework of MOF-808 along with mobile potassium ions present in the resulting material (MOF-808-SO3K), the MOF-808-SO3K-based solid-state electrolyte achieves an ionic conductivity of 3.1 × 10–5 S/cm at 303 K, a low activation energy of 0.32 eV, and a high transference number of 0.76 for potassium ions. The compound shows good long-term cycling stability with potassium metal during the charge–discharge processes. First-principles calculations are further performed to probe the structure of MOF-808-SO3K and gain insights into the ionic conduction of potassium ions in MOF-808-SO3K.

Metal-organic-based electrode materials are increasingly appealing because both metal and organic linker are capable of undergoing redox processes, thus offering a high specific capacity. High porosity which can be achieved...

An online survey was developed to map Extension's presence in divorce education initiatives and to catalogue the amount, type, and availability of resources that each state has dedicated to meeting the needs of this parent audience. Requests for participation were sent to members on the National Extension Human Service listserv and resulted in representation from 48 out of 50 states and one U. S. territory. Results document a national presence, outline the nature and expression of Extension divorce education programs, and suggest a direction for future collaboration related to this topic.
