Curriculum Innovations: A Podcast-Based Neurologic Emergency Flipped Classroom Curriculum for Neurology Residents.

Introduction: Education on the management of neurologic emergencies is vital for neurology residents, and effective educational methods are needed. This study aims to implement and evaluate the impact of a podcast-based flipped classroom curriculum in neurologic emergencies. "Flipped classroom" instructional methods have been used in GME and informed by experiential learning theory.

Global Impact of the COVID-19 Pandemic on Stroke Volumes and Cerebrovascular Events: A 1-Year Follow-up.

Background And Objectives: Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).

Does stapedotomy improve high frequency conductive hearing?

Objectives: Stapedotomy is performed to address conductive hearing deficits. While hearing thresholds reliably improve at low frequencies (LF), conductive outcomes at high frequencies (HF) are less reliable and have not been well described. Herein, we evaluate post-operative HF air-bone gap (ABG) changes and measure HF air conduction (AC) thresholds changes as a function of frequency.

Fast Li-Ion Conduction in Spinel-Structured Solids.

Spinel-structured solids were studied to understand if fast Li ion conduction can be achieved with Li occupying multiple crystallographic sites of the structure to form a "Li-stuffed" spinel, and if the concept is applicable to prepare a high mixed electronic-ionic conductive, electrochemically active solid solution of the Li stuffed spinel with spinel-structured Li-ion battery electrodes. This could enable a single-phase fully solid electrode eliminating multi-phase interface incompatibility and impedance commonly observed in multi-phase solid electrolyte-cathode composites. Materials of composition LiM(III)TiO, M(III) = Cr or Al were prepared through solid-state methods.

Enabling "lithium-free" manufacturing of pure lithium metal solid-state batteries through in situ plating.

The coupling of solid-state electrolytes with a Li-metal anode and state-of-the-art (SOA) cathode materials is a promising path to develop inherently safe batteries with high energy density (>1000 Wh L). However, integrating metallic Li with solid-electrolytes using scalable processes is not only challenging, but also adds extraneous volume since SOA cathodes are fully lithiated. Here we show the potential for "Li-free" battery manufacturing using the LiLaZrO (LLZO) electrolyte.
