Welcome to the Nanomaterials and Energy Devices Laboratory at Vanderbilt University. We are a resonantly productive team of researchers who have a passion to explore new ways to solve challenges in the area of energy and environmental applications. In the past, our work has centered on the synthesis and manufacturing of nanomaterials, energy storage, energy harvesting, and environmental applications. Moving forward, we’re excited to solve problems using economical nanotechnology to address (1) a sustainable, and (2) a smart and connected future. We work in fields of research where one advance can impact billions of people on challenges where the lack of effort and creative solutions can threaten the sustainability of the human population. This includes big solutions to problems in renewable energy and greenhouse gas conversion, among technologies that can advance energy technology development without destroying our environment. Our team has a strong background in spinning research into commercial ventures, close interactions with industry through funding or collaboration, and a habit of approaching fundamental directions with hypothesized technology outcomes. Read more about recent exciting news from our lab below, more about our research at our research page, and check out our most recent publications and patents on our publications page.
Most of all, if you are up for engaging discussion about energy systems, Prof. Cary Pint’s favorite pastime is chatting about world-impacting ideas about energy systems over a shot or two of espresso. Stop by!!
RECENT EVENTS AND NEWS FROM OUR GROUP
October 4th, 2018: We are proud to host Prof. Yi Cui from Stanford, who is the world’s leading researcher on nanomaterials for batteries, at Vanderbilt! Prof. Cui gave a talk at our annual Nanoday event in VINSE, where students across Vanderbilt presented posters on their work involving nanotechnology. We’re very proud of Ms. Anna Douglas (center) and Mr. John Waugh (red) who won #1 place overall best poster, and #1 best poster among first year graduate students, respectively. Shown in this picture is John and Anna along with Yi after his talk and at the conclusion of the Nanoday event.
September 3rd, 2018: It is a sad day in the Pint Lab. Mr. Thomas Metke has officially left our team and started graduate school as a Presidential Fellow in the Mechanical Engineering program at Princeton. Tommy started research with us when he was just a junior in high school. Then, he came to Vanderbilt to continue research with us until he completed his 4-year degree. Summer after summer, and year after year, Tommy has been a key part of our lab for now approaching 6 years. When he wasn’t doing independent projects and rubbing shoulders with grad students and postdocs, he was doing things in the background like fixing the glove box and building a ball mill that made everyone’s research projects move forward. Tommy completed several independent projects. He demonstrated the first capacitive deionization process using silicon materials, he engineered non-flammable solid state electrolytes, and he demonstrated a way to incorporate energy storage into solar photovoltaic cells in a very elegant way! Relative to some research groups, that level of independent progress would be grounds for granting the Ph.D. degree! Moreover, he was always someone who brought an excitement for research that made working with him and around him a pleasure. We’ll miss you Tommy! Good luck on the next step of your career!
August 30, 2018: Anna Douglas and Cary Pint took on the 36:86 Entrepreneurship meeting in Nashville, TN. Anna rocked the house with a pitch on SkyNano’s technology, and Pint and Douglas spent the rest of the time meeting investors and discussing our technology that makes up the basis of SkyNano LLC, and spun out from research efforts in the Pint Lab.
August 2, 2018: A warm goodbye to our summer REU student, Rebeca Gurrola, who presented a poster today on her summer research in our group. She started a challenging project to incorporate an electrochemical energy harvester into a fabric template, and not only did that, but her work has resulted in the best performing energy harvesting material ever recorded to date. Pictured is Rebeca with her graduate student mentor, Janna Eaves, holding an award for best poster design from the REU poster session. Way to go Rebeca!
