An Initiative to Improve Performance on a National Transition of Care Measure and to Reduce Readmissions in an Academic Psychiatric Hospital.

Background: Inpatient psychiatry discharge planning through careful transition documentation may reduce adverse patient outcomes and decrease hospital readmissions. In 2017 a national psychiatry reporting program instituted a quality metric called the Transition Record with Specified Elements Received by Discharged Patients (TR-1). At Yale New Haven Psychiatric Hospital, the TR-1 metric had 0% provider compliance when the quality metric was instituted.

Novel Anion Exchange Membrane Based on Poly(Pentafluorostyrene) Substituted with Mercaptotetrazole Pendant Groups and Its Blend with Polybenzimidazole for Vanadium Redox Flow Battery Applications.

In order to evaluate the performance of the anion exchange membranes in a vanadium redox flow battery, a novel anion exchange polymer was synthesized via a three step process. Firstly, 1-(2-dimethylaminoethyl)-5-mercaptotetrazole was grafted onto poly(pentafluorostyrene) by nucleophilic F/S exchange. Secondly, the tertiary amino groups were quaternized by using iodomethane to provide anion exchange sites.

Electrowinning of Iron from Spent Leaching Solutions Using Novel Anion Exchange Membranes.

In the Pyror process, electrowinning (EW) is used to recover acid and iron from spent leaching solutions (SLS), where a porous Terylene membrane acts as a separator between the cathode and anode. In this study, a novel anion exchange membrane (AEM)-based EW process is benchmarked against a process without and with a porous Terylene membrane by comparing the current efficiency, specific energy consumption (SEC), and sulfuric acid generation using an in-house constructed EW flow cell. Using an FAP-PK-130 commercial AEM, it was shown that the AEM-based process was more efficient than the traditional processes.

Performances of Anion-Exchange Blend Membranes on Vanadium Redox Flow Batteries.

Anion exchange blend membranes (AEBMs) were prepared for use in Vanadium Redox Flow Batteries (VRFBs). These AEBMs consisted of 3 polymer components. Firstly, PBI-OO (nonfluorinated PBI) or F6-PBI (partially fluorinated PBI) were used as a matrix polymer.

Density functional theory study with and without COSMO of H SO reactions in an aqueous environment for metal extraction.

In a recent study investigating the suitability of solvent extraction (SX) for the separation of Ta and Nb, it was shown that speciation data would be required to help explain the data obtained. As traditional speciation techniques cannot be readily applied for Ta and Nb, it was decided to determine the suitability of molecular modeling for this purpose. During the SX experiments the aqueous phase consisted of sulfuric acid (H SO ), water, and metal species.
