Investigating the Mechanism of Rare-Earth Ion Incorporation into Glass-Ceramic Crystal Phases through Er Ion Probe Characteristics.

Exploring the intrinsic mechanisms of rare-earth ions entering the crystal phase has great significance for finely tuning the luminescent properties of glass-ceramics. Using Er ions as a probe, X-ray diffraction was employed to precisely measure the crystallinity of SiO-PbF-ErO glass-ceramics synthesized under various heat treatment conditions, confirming the occurrence of a rapid crystallization process. Additionally, by combining Judd-Ofelt theory with comprehensive analyses of absorption and fluorescence spectra, we calculated the relative proportions of Er ions present in the crystal phase.

Preoperative Risk Factors for Predicting Postoperative Human Serum Albumin Infusion after Hip Fracture Surgery: Development and Validation of a Nomogram.

Background: As one of the adverse events after hip fracture surgery, hypoalbuminemia is usually treated using human serum albumin infusion. However, the application of human serum albumin may cause complications such as postsurgical infection and increased mortality.

Aims: To examine the preoperative risk factors of human serum albumin infusion after hip fracture surgery, establish a nomogram prediction model, and verify its accuracy.
