Modified Kirchhoff's law; how the rules have been changed at the intersections.

Ankur Gupta

Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes.

While not possible yet, new research by a team of CU Boulder scientists could potentially lead to such advances.

Published today in the Proceedings of the National Academy of Science, researchers in Ankur Gupta’s lab discovered how tiny charged particles, called ions, move within a complex network of minuscule pores. The breakthrough could lead to the development of more efficient energy storage devices, such as supercapacitors, said Gupta, an assistant professor of chemical and biological engineering.

“Given the critical role of energy in the future of the planet, I felt inspired to apply my chemical engineering knowledge to advancing energy storage devices,” Gupta said. “It felt like the topic was somewhat underexplored and as such, the perfect opportunity.”

Gupta explained that several chemical engineering techniques are used to study flow in porous materials such as oil reservoirs and water filtration, but they have not been fully utilized in some energy storage systems.

The discovery is significant not only for storing energy in vehicles and electronic devices but also for power grids, where fluctuating energy demand requires efficient storage to avoid waste during periods of low demand and to ensure rapid supply during high demand.

Supercapacitors, energy storage devices that rely on ion accumulation in their pores, have rapid charging times and longer life spans compared to batteries.

“The primary appeal of supercapacitors lies in their speed,” Gupta said. “So how can we make their charging and release of energy faster? By the more efficient movement of ions.”

Their findings modify Kirchhoff’s law, which has governed current flow in electrical circuits since 1845 and is a staple in high school students’ science classes. Unlike electrons, ions move due to both electric fields and diffusion, and the researchers determined that their movements at pore intersections are different from what was described in Kirchhoff’s law.

Prior to the study, ion movements were only described in the literature in one straight pore. Through this research, ion movement in a complex network of thousands of interconnected pores can be simulated and predicted in a few minutes.

“That’s the leap of the work,” Gupta said. “We found the missing link.”

This work was funded by National Science Foundation CAREER Award # 2238412.

Published in the Proceedings of the National Academy of Science, researchers in Ankur Gupta’s lab are working on improving supercapacitors for energy storage by studying how they store energy at the nanoscale.

My research leverages computational tools to address questions in immunology, inflammation and cancer. Specifically, I aim to investigate novel therapeutics between Alzheimer’s Disease and glioma, using physics-based simulations to identify and target mechanisms that disrupt the tumor immunoediting process. One of my current projects is investigating how TREM2, a protein expressed on the immune cells of the brain, can mediate tumor suppression mechanisms of a platinum-IV chemotherapeutics in colorectal cancer. Creative applications of computational pipelines allow me to ask new questions at the interface of immunology, oncology and engineering, hopefully leading to solutions to urgent challenges.

My research focuses on development of software and techniques for constructing and modeling general organic polymer systems at the atomic, molecular and nanoscale using molecular dynamics. Polymer design is essential to many active research areas including identifying suitable sustainable and recyclable plastics, compatibilizing polymer-biopolymer interfaces for biomedical engineering and therapeutics, and designing self-healing materials with dynamic covalent networks. However, systematic exploration of chemical and morphological polymer design spaces is practically impossible using experimental methods alone and requires assistance from computational structure-function models. I am currently active in two sustainability-driven collaborations with the National Renewable Energy Laboratory (NREL), dealing with high-throughput screening of biomass-derived replacements for petroleum plastic monomers and lignin-derived replacements for common commercial plasticizers, respectively.

Some immune cell types are particularly good at migrating to sites of inflammation, such as solid cancer tumors. The goal of my project is to harness this capability of immune cells to bring drug-loaded nanoparticles directly to diseased tissue. To do so, I will investigate nanoparticle engineering, the ability of sound waves to purify cells, and the effect of nanoparticles on immune cell behavior. My hope is that the work done in this project will improve accessibility and patient outcomes for cell-based immunotherapies for a variety of treatment scenarios.
