Materials with multiple principal elements (middle- and high-entropy materials), are used in emerging applications in various fields due to their unique properties, driven by configuration entropy. Improved understanding and experimental investigations of the impact of the entropy of mixing on the properties of these materials are of large practical interest. Here we show a simplified limited area calculation approach for assessing the entropy of mixing using a CoCuFeNi model nanoalloy.

A novel approach for the correlation of local martensite tetragonality determined by electron backscatter diffraction and carbon distribution by atom probe tomography (APT) is presented. The two methods are correlated by site-specific sample preparation for APT based on the local tetragonality. This approach is used to investigate the local carbon distribution in high carbon steel with varying local martensite tetragonality.

Introduction: Analyses of simulation performance taking place during postsimulation debriefings have been described as iterating through phases of unawareness of problems, identifying problems, explaining the problems and suggesting alternative strategies or solutions to manage the problems. However, little is known about the mechanisms that contribute to shifting from one such phase to the subsequent one. The aim was to study which kinds of facilitator interactions contribute to advancing the participants' analyses during video-assisted postsimulation debriefing.

Article Synopsis
  • A study in Sweden examined the cardiovascular health of 2,588 infants with Down syndrome born between 1992 and 2012, focusing on congenital heart defects.
  • The research found that 54% of these infants had some type of congenital heart defect, with a notable decline in complex defects over time, almost 40% lower for infants born in 2010 to 2012 compared to those born in 1992 to 1994.
  • However, there was an increase in isolated defects like ventricular septal defect and atrial septal defect in more recent years, suggesting possible factors like selective abortion and improved fetal diagnostics may be influencing these trends.
