Metastructure-Based Pressure Sensors

PhD students Huan Zhao and Julia Huddy, and professors Yan Li and Will Scheideler are coauthors of "Rational Design of 3D-Printed Metastructure-Based Pressure Sensors" published in Advanced Engineering Materials. The study found that metastructure architecture design can lead to substantial expansion of the sensing range. The practical application of this technology was demonstrated in an undergraduate ENGS 33 bridge project.

Best Paper Award

Professor Vikrant Vaze received the INFORMS AAS Best Paper Award this week at the INFORMS annual meeting in Phoenix. The paper entitled, "Choice-Based Airline Schedule Design and Fleet Assignment: A Decomposition Approach," proposes a "decomposition approach based on partitioning the flight network into smaller subnetworks by exploiting weak dependencies in network structure."

En Route to Better Batteries

PhD student Peiyu Wang, Professor Weiyang (Fiona) Li, and researchers from Stanford University are authors of "High-Performance Lithium−Sulfur Batteries via Molecular Complexation," published in the Journal of the American Chemical Society. This study presents a new route to design and tailor liquid-sulfur-based cathodes with excellent solubilities of solid discharge products to greatly improve the reversibility, stability, cycling performance, and low-temperature capabilities of Li−S batteries.

Printing Solar Cells

PhD student Julia Huddy and Professor William Scheideler co-authored "Rapid 2D Patterning of High-Performance Perovskites Using Large Area Flexography" published in Advanced Functional Materials. The study leverages high-speed flexographic printing to deposit critical materials for perovskite solar cells over large areas, creating a scalable method for manufacturing and future commercialization.

Best Paper Award

PhD student Michele Maxson was invited to present her work with professor Fridon Shubitidze entitled, "Active Bucking Using a System On a Chip Field Programmable Gate Array for Geophysical Investigations" at the Near Surface Geoscience conference in Edinburgh, Scotland last week. The invitation came as part of a "best paper" award earlier this year at the 35th Symposium on the Application of Geophysics to Engineering and Environmental Problems in New Orleans.

Best Abstract Award

PhD student Megan Clark won "best abstract" for her work to be presented at the Flash Radiotherapy and Particle Therapy (FRPT) conference this December in Toronto. Her work is titled, "High-speed Quantitative Imaging for Retrospective Quality Assurance FAST-01 Clinical Treatment Fields." This novel technology, developed at Dartmouth, can image scanning proton beams at up to 12 kHz and verify that therapeutic beams are delivered as planned.

Wellness in Med School

Professor Wesley Marrero will co-lead a project funded by the American Medical Association's ChangeMedEd Innovation Grant Program, which adopts the holistic "Precision Well-Being" approach to create personalized wellness solutions for optimal learning and wellness in medical school. The team includes Thayer PhD student Zequn Chen, Geisel professors Thomas Thesen and Matthew Duncan, and LeChauncy Woodard at the University of Houston College of Medicine.

On the Cover

PhD candidate Xin Yue was featured on the (virtual) cover of Sensors in July for his work on a 20 million frames-per-second image sensor that can capture 108 sequential image frames over a period of 5.4 microseconds in burst mode. The sensor was designed and tested by Dartmouth for the Los Alamos National Laboratory for ultra-high-speed materials analysis. Yue, who recently completed his dissertation, is working for Apple in California.

Spidey-Sensors

PhD students Huan Zhao and Xiangbei Liu, and Professor Yan Li co-authored "The Role of Fracture Patterns on Crack-Based Strain Sensors" published in the Journal of Engineering Materials and Technology. Taking inspiration from the vibration detection mechanism employed by spiders, this computational study provides physical insights for the design and manufacturing of crack-based strain sensors across various applications.
