The unique properties and processability of conducting and semiconducting organic materials have fascinated scientists since their discovery. Of this broad class of materials, conductive coordination polymers are of immense recent interest due to their innate modularity and tunability. However, these materials are typically generated as powders and, in some cases, single crystals which significantly limits possible processing and many applications.

Direct exchange coupling between an organic radical and a metal is frequently stronger than superexchange through diamagnetic ligands, and the strategy of using organic radicals to engender desirable magnetic properties has been an area of active investigation. Despite significant advances and exciting bulk properties, the magnitude of for radical linkers bridging paramagnetic centers is still difficult to rationally predict.

The purpose of this study is to design a standard prevention bundle that decreases the rate of hypothermia among infants after birth and to investigate efficacy of the bundle and short-term outcomes for VLBW infants.
Methods: This quality improvement project was conducted from February 2017 to July 2018 on all VLBW preterm infants admitted at a single referral level III neonatal intensive care unit.
Ligands play a crucial role in the supramolecular photoluminescence properties of Pt(II) square-planar complexes. To improve the luminescence color responses of N∧C∧N cyclometalated Pt(II) complexes to external stimuli such as mechanical stress and chemical vapors, we have conducted a steric engineering of the previous systems - [ , 56, 4978-4989] by introducing two -butyl groups to the tridentate ligand to form complexes -. Unlike the "too low" or "too high" steric hindrance of the NCNPt core in -, the combined steric effects of the -butyl groups at one side and the pentiptycene group at the other side of the NCNPt core in are "just right" for generating as-prepared powders with pure monomer (green) emission or pure excimer (red) emission, depending on the rate of precipitation from solutions.

However, nursing practice differs among individuals, and an inappropriate application method may delay the respiratory therapy, influence the beneficial effect of NCPAP, and increase complications. We introduced a quality improvement project to expedite the application of NCPAP therapy and decrease the incidence of nasal trauma.
