Chemical and Electrochemical Characterization of Hot-Pressed LiPSCl Solid State Electrolyte: Operating Pressure-Invariant High Ionic Conductivity.

Sulfide solid state electrolytes (SSE) are among the most promising materials in the effort to replace liquid electrolytes, largely due to their comparable ionic conductivities. Among the sulfide SSEs, Argyrodites (LiPSX, X=Cl, Br, I) further stand out due to their high theoretical ionic conductivity (~1×10 S cm) and interfacial stability against reactive metal anodes such as lithium. Generally, solid state electrolyte pellets are pressed from powder feedstock at room temperature, however, pellets fabricated by cold pressing consistently result in low bulk density and high porosity, facilitating interfacial degradation reactions and allowing dendrites to propagate through the pores and grain boundaries.

Reference Electrode Reveals Insights on Sodium Metal/Solid Electrolyte Interface Cycling and Voiding Behaviors at High Current Densities and Areal Capacities.

Plating and stripping processes at solid metal electrode/solid electrolyte interfaces are of great significance for high-energy, solid-state batteries. Here, we introduce a Na metal reference electrode to a symmetric Na metal/sodium β″ alumina/Na metal cell and study both cycling and unidirectional protocols with a focus on high current density and areal capacity. For example, in a current ramp test at 5 mAh cm we find a shift from stable to unstable interfacial polarization during stripping at ≳3 mA cm, and at 7.

Rapid E-Learning for professional development in school-based diabetes management.

The number of school aged youth in the United States requiring assistance in the management of diabetes has reached over 200,000. School nurses are often charged with the training of personnel and provision of assistance to children with this chronic disease. The need for quick, efficient, and accessible training methods is necessary to ensure school nurses have the most current information necessary to perform their duties.

Exploring Public Health and Nursing Students' Perceptions of Each Other's Professional Roles.

Public health education specialists and nurses often work interprofessionally in the public health setting. Using a mixed-methods design, this exploratory study evaluated the effect of an online interprofessional case study activity on nursing and public health education students' perceptions of each other's professional role. For the public health experimental group only, a statistically significant change (p < .

Rural elementary students', parents', and teachers' perceptions of bullying.

Objective: To examine the prevalence and correlates of bullying in 7 rural elementary schools from students', parents', and teachers' perspectives.

Method: Surveys were completed by 739 fourth, fifth, and sixth grade students, 367 parents, and 37 teachers.

Results: Students tended to report higher prevalence of bullying than did parents or teachers, and their reports were associated with aggression, attitudes toward violence, and perceptions of school safety.
