Early Detection of Internal Bleeding
PhD student Navid Rashedi (pictured), Professor Ethan Murphy, Alexandra Hamlin '16 Th'17 Th'19, research associate Victor Borza, and Professors Jonathan Elliott, Ryan Halter, and Vikrant Vaze are co-authors of: "Detection of occult hemorrhage using multivariate non-invasive technologies" published in Physiological Measurement. "This work investigated machine learning to combine multiple technologies—electrical impedance and near infrared spectroscopy—to better detect internal bleeds in a porcine study. Internal bleeds are often not detectable until it's too late. This approach appears to detect them earlier and more accurately," said Murphy.
Thin Film Transistors
PhD students Samuel Ong, Simon Agnew, and Md Saifur Rahman, and Professor Will Scheideler co-authored "Sub-nm kinetically controlled liquid metal printing of ternary antimony indium oxide transistors" published in Matter. "Our study shows how to harness the kinetics of liquid metal oxidation to control the thickness at the single-nm scale for synthesizing 2D transparent semiconducting films with finely tuned electrostatics for thin film transistors. These ultrathin metal oxides could enable flexible electronics capable of withstanding extreme bending stress and deformation," said Scheideler.
Novel Piezo-Composites
PhD students Huan Zhao, Ya Tang, and Xiangbei Liu, undergraduate students Andrew Kim and Jace Henry, and Professor Yan Li co-authored "High-temperature piezoelectric composites with enhanced structural integrity" published in Ceramics International. "This article reports a novel piezoelectric composite that can increase the temperature limit to 500°C while maintaining good structural integrity and mechanical performance. This innovative piezo-composite opens new possibilities for sensing, energy harvesting, and actuation in high-temperature environments," said Li.
NEAAPM Symposium Winners
Jacob Sunnerberg and Conner Ubert, PhD candidates in the Medical Physics Education Program, respectively won first and second place at the New England chapter of the American Association of Medical Physicists Early Career Symposium. They were one of eight Dartmouth students and researchers to compete in the Early Investigator Competition.
