Probing the Saltwater Immersion Effect on Buried Interfacial Structures between a Sealant and Adhesion Promoter at the Molecular Level.

In this research, we used sum frequency generation vibrational spectroscopy to investigate the buried interface of a thiol-epoxy model aerospace sealant in contact with a silane-based adhesion promoter (6111) following exposures to 3% saltwater at elevated temperatures and elevated temperatures alone. The results suggest that the saltwater caused a change at the interface between the adhesion promoter and sealant, while an elevated temperature of 60 °C itself did not affect the interfacial structure noticeably. Model hydrolyzed and nonhydrolyzed silanes were also used in the study to compare with the adhesion promoter 6111 to understand the interfacial behavior of main silane components in 6111 as well as their potential role in adhesion.

Transformation of Care: Integrating the Registered Nurse Care Coordinator into the Patient-Centered Medical Home.

The purpose of this quality improvement project was to implement and evaluate a care delivery model integrating the registered nurse care coordinator (RNCC) into a family practice that is certified as a patient-centered medical home (PCMH) by the National Committee for Quality Assurance. The initial target population was the 937 patients with diabetes in the family practice. A pre-post design was used to assess changes in patients' diabetic quality indicators after integrating the role of RNCC using existing staff.
