Research Quick Takes

Best Paper Award

PhD student Michele Maxsonwas 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 Clarkwon "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 Thesenand Matthew Duncan, and LeChauncy Woodard at the University of Houston College of Medicine.

On the Cover

PhD candidate Xin Yuewas 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 Zhaoand 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.

Early Career Runner-Up

PhD student Savannah Deckerwon 2nd place at the 2023 Early-Career Investigator Symposium of the American Association of Physicists in Medicine in Houston, TX. Her submission, "Expanding the inclusivity of Cherenkov surface dosimetry by quantifying the effects of skin tone in a multi-institutional human study," was one of 10 chosen from the hundreds submitted for oral presentation in the competition.

2D Materials for H2 Production

Postdoc Anand Tiwari,PhD students Shay McBride, Andrew Hamlin, Md Saifur Rahman,and Julia Huddy, and professors Geoffroy Hautier , and William Scheideler are co-authors of a study on designing 2D titanium carbide materials for hydrogen (H ₂ ) production. Published in ACS Sustainable Chemistry and Engineering , the study developed strategies to dope 2D MXenes with sulfur and nitrogen to engineer their activity as efficient—as well as low-cost and earth-abundant—electrocatalysts for large-scale H ₂ production.

Measuring the Impact of Climate Legislation

Professor Erin Mayfield is a co-author of " Emissions and energy impacts of the Inflation Reduction Act " published in Science . The paper leverages "results from nine independent, state-of-the-art models to examine potential implications of key IRA provisions, showing economy-wide emissions reductions between 43 and 48% below 2005 levels by 2035."

Subglacial Hydrology & Ice Dynamics

Research Scientist Aleah Sommersand Professor Colin Meyer applied a simpler form of the SHAKTI subglacial hydrology model to the Helmheim Glacier in Greenland to predict high water pressure and other variables in seawater movement under glacial ice. Their model improves upon current models by reducing reliance on unconstrained parameters, which have posed challenges to reproducing results. Their findings were published in the Journal of Glaciology .

Best Student Presentation

At this year's IEEE Photovoltaics Specialty Conference in Puerto Rico, PhD student Julia Huddyreceived an award for best student presentation for a talk about her work in the SENSE Lab titled "Large-Area Uniformity Mapping of High-Speed Flexography-Printed Perovskite Solar Cells via Scanning Photoluminescence."

NSF Engines Semifinalist

Professors Liz Murnane , Vikrant Vaze , and Wesley Marrero are lead faculty on a team selected as one of 34 semifinalists for the inaugural NSF Regional Innovation Engines competition —spanning nearly all key technology areas and societal and economic challenges highlighted in the " CHIPS and Science Act ." A partnership with UMass Lowell, their proposed engine is titled, "Advancing Health Equity Through Digital Technologies, Data Infrastructure, and Artificial Intelligence." Each Engine could receive up to $160 million over 10 years.

Better 3D-Printed Electrodes

PhD students Julia Huddyand Huan Zhao, research associate Anand Tiwari, and Professors Yan Li and William Scheideler authored " Graph Theory Design of 3D Printed Conductive Lattice Electrodes " published in Advanced Materials Technologies . This work aims to model the electrical behavior of 3D lattice structures to guide the design of 3D printed electrodes for electrochemical device applications.
