Imaging Bias-Driven Domain Wall Motion With Scanning Oscillator Piezoresponse Force Microscopy.

Understanding ferroelectric domain wall dynamics at the nanoscale across a broad range of timescales requires measuring domain wall position under different applied electric fields. The success of piezoresponse force microscopy (PFM) as a tool to apply local electric fields at different positions and imaging their changing position, together with the information obtained from associated switching spectroscopies has fueled numerous studies of the dynamics of ferroelectric domains to determine the impact of intrinsic parameters such as crystalline order, defects and pinning centers, as well as boundary conditions such as environment. However, the investigation of sub-coercive reversible domain wall vibrational modes requires the development of new tools that enable visualizing domain wall motion under varying applied fields with high temporal and spatial resolution while also accounting for spurious electrostatic effects.

Proximity ferroelectricity in wurtzite heterostructures.

Proximity ferroelectricity is an interface-associated phenomenon in electric-field-driven polarization reversal in a non-ferroelectric polar material induced by one or more adjacent ferroelectric materials. Here we report proximity ferroelectricity in wurtzite ferroelectric heterostructures. In the present case, the non-ferroelectric layers are AlN and ZnO, whereas the ferroelectric layers are AlBN, AlScN and ZnMgO.

Assembly and performance of a cholera RDT prototype that detects both and associated bacteriophage as a proxy for pathogen detection.

Cholera rapid diagnostic tests (RDTs) are vulnerable to virulent bacteriophage predation. We hypothesized that an enhanced cholera RDT that detects the common virulent bacteriophage ICP1 might serve as a proxy for pathogen detection. We previously developed a monoclonal antibody (mAb) to the ICP1 major capsid protein.

COEPA ready: Innovative pedagogy for integrating social determinants of health in PharmD curricula.

Background: The American Association of Colleges of Pharmacy Curriculum Outcomes and Entrustable Professional Activities (COEPA) recognize the need for social determinants of health (SDH) education for pharmacy learners. However, there is a dearth of published strategies for incorporating comprehensive SDH education in Doctor of Pharmacy curricula. The objectives of this study were to: 1) highlight unpublished exemplars of SDH teaching models and 2) propose strategies for teaching SDH.
