Enhancement of Spontaneous Orientation Polarization in Glassy Organic Semiconductor Mixtures.

The alignment of permanent dipole moments and the resulting spontaneous orientation polarization (SOP) are commonly observed in evaporated neat films of polar organic molecules and lead to a so-called giant surface potential. In the case of mixed films, often enhanced molecular orientation is observed, i.e.

Influence of Process Conditions During Aqueous and Direct Recycling of NMC811 Cathodes.

This study investigated the impact of various process conditions on the aqueous, direct recycling of LiNiMnCoO (NMC811) cathodes. Three model systems were used. The first system assumes that the current collector delamination is performed in a dry environment without the use of water as a process medium.

Factors Associated With Potentially Unnecessary Transfers for Children With Asthma: A Retrospective Cohort Study.

Objective: Our objective was to identify the hospital- and community-related factors associated with the hospital-level rate of potentially unnecessary interfacility transfers (IFTs) for pediatric patients with asthma exacerbations.

Methods: We analyzed California Emergency Department (ED) data from 2016 to 2019 to capture ED visits where a pediatric patient (age, 2-17 years) presented with an asthma exacerbation and was transferred to another ED or acute care hospital. The primary outcome was hospital-level rate of potentially unnecessary IFTs, defined as a visit where length of stay after transfer was <24 hours and no advanced services (eg, critical care) were used.
