Welcome to the Nanomaterials and Energy Devices Laboratory at Vanderbilt University.  We are a team of creative, passionate, and disciplined researchers with a focus on using interdisciplinary skills to engineer solutions to big problems.  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.  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.  If you want to know more about us, learn how to join us, or have a conversation on technologies that can change the world over a shot of espresso – feel free to contact Cary Pint at cary.l.pint at Vanderbilt.edu!



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!


July 2, 2018: Congratulations Dr. Mengya Li!  Today, she brilliantly defended her Ph.D. thesis entitled “Nanomanufacturing of nanocomposites for energy storage and environmental applications” as the seventh Ph.D. granted from the Pint lab team! Her work has been the foundation for our ongoing efforts to build complex 3-D materials with nanoscale precision using industrially-scalable methods.  She will continue her work as a postdoc in the battery manufacturing facility at Oak Ridge National Laboratory later this summer.  We’re very proud of you Mengya, and thank you so much for all the hard work you’ve put in – you inspire us!!


June 1, 2018: Making headlines!  A new research paper from the Pint team published in ACS Applied Materials & Interfaces highlights the scientific challenges toward using carbon dioxide to make the novel and valuable single-walled carbon nanotubes, but while making the smallest diameter nanotubes and hence most valuable materials ever produced from carbon dioxide captured from the air.  Among the many press outlets that have covered our exciting results, here is a blurb from Popular Mechanics.


May 22, 2018: Prof. Pint has been traveling the past few weeks giving invited talks.  Recently, last week Prof. Pint gave an invited talk in the 3M Nanotech Forum Seminar Series, and today Prof. Pint gave an invited talk at the Techtextil North America Conference in a symposium focused on Smart Textiles.  The Pint’s team work on energy harvesting materials integrated into smart and connected textile systems was well received and an exciting emerging area of our research program!

April 3, 2018: Massive congratulations to Ms. Kate Moyer.  She has been awarded a highly selective GRFP Graduate Fellowship through the National Science Foundation.  This is an extremely competitive national award, and generally comes with ~ 15% success ratio that is often frontloaded by the top few ranked research institutions.  Kate marks the fourth NSF Graduate fellow on our team in a row, giving an 80% success ratio for our laboratory among the last 5 fellowship applicants.  Way to go Kate!  As we recruit and build the next and more productive phase of the Pint lab in coming years, these extraordinary folks leave big shoes to fill!

MRSApril 2, 2018: The Pint Lab is at MRS this week!  We have 6 presentations throughout the course of the week on topics ranging from biomechanical energy harvesters, recycling of materials into sodium batteries, ultra fast charging battery configurations, and extremely low energy input and high areal capacity electrophoretic battery manufacturing.  Come see our talks, and visit with us!


April 1, 2018: Prof. Pint and his team have been awarded a grant through NASA to develop a structural battery that can be integrated into a CubeSat structural frame, in collaboration with researchers at the University of Miami, and NASA Kennedy Space Center.  Excited to see batteries flying in space!


March 29, 2018: Prof. Pint gave an invited talk at the International Battery Seminar held in Fort Lauderdale, FL to a crowd that was wonderfully mixed between academic researchers, industry manufacturers and engineers, and national lab researchers.  Pint talked about the discovery that mechanics can influence battery performance, and the ways in which this opens up new markets and technologies outside of energy storage for the battery industry.


March 12, 2018: Congratulations to Ms. Kate Moyer!  She was awarded a prestigious summer internship at NASA Kennedy Space Center starting in June to work on a collaborative project between NASA KSC and the Pint Lab focused on making and testing a multifunctional structural battery.   Way to go Kate!

image1April 21-25, 2017: Prof Pint delivered an invited talk at the 2017 Guadalupe workshop on Nucleation and Growth Mechanisms of Atomically Thin Nanomaterials – similar to a Gordon workshop, but held at the Guadalupe river ranch in TX.  Pint’s talk focused on efforts aiming to achieve small diameter CNT growth from ambient CO2.  Shown in the picture is a historic team of researchers (including Prof. Pint, right) that made huge leaps in understanding of carbon nanotube growth science.

February 2017 Congratulations to Rachel Carter for her work published in Nano Letters entitled, “A Sugar Derived Room Temperature Sodium Sulfur Battery with Long Term Cycling Stability” and corresponding press release that was independently picked up through IOP’s Nanotechweb.org.  Notably, this paper was also one of the Most Read papers in Nano Letters during the month of February and early March, and describes a process to produce sodium sulfur batteries from (very cheap!) table sugar, bulk sodium, and bulk sulfur that involve a stable anode-electrolyte-cathode configuration that results in excellent cycling performance.  Go Rachel!
