Energy

Fuel cells · ion-selective membranes
2026Room-temperature pulsed laser deposition of boron nitride for enhanced fuel cell selectivityEnergyACS Nano · lead author

S. Kutagulla, P. T. Carmichael, A. Biswas, D. Mutyala, T. Terlier, N. H. Le, et al.

Why it matters

Boron nitride usually needs high temperatures to grow, which would destroy a polymer membrane. Growing it at room temperature, directly on a finished commercial membrane, makes the approach fit how membranes are actually made.

20% higher power density and 32% less hydrogen crossover than the industry-standard membrane.

2025Ozonated monolayer graphene for extended performance and durability in hydrogen fuel cell electric vehiclesEnergyACS Nano · lead author

S. Kutagulla, P. Carmichael, M. Coupin, D. Mutyala, N. Ignacio, N. H. Le, et al.

Why it matters

Perfect graphene blocks everything, including the protons a fuel cell needs. UV-ozone treatment adds controlled defects that let protons through while keeping hydrogen out, without weakening the graphene. Durability matters most for fuel cells in vehicles, which have to last for years.

2025Monolayer graphene mediated OH⁻/HCO₃⁻ selectivity enhancement in Sustainion anion-exchange membranesEnergyMRS Bulletin · lead author

S. Kutagulla, D. King, P. Carmichael, C. R. Barnett, U. Misra, P. R. Kidambi, et al.

Why it matters

Takes the graphene-barrier idea from proton membranes to anion-exchange membranes, which are used in electrolyzers and CO₂ conversion. A single graphene layer improves how well the membrane passes hydroxide ions over bicarbonate.

2023Comparative studies of atomically thin proton conductive films to reduce crossover in hydrogen fuel cellsEnergyACS Applied Materials & Interfaces · lead author

S. Kutagulla, N. H. Le, I. T. Caldino Bohn, B. J. Stacy, C. S. Favela, J. J. Slack, et al.

Why it matters

A head-to-head test of several atom-thin films as hydrogen barriers inside working fuel-cell membranes. It showed which materials were worth pursuing, and set up the graphene and boron nitride work that followed.

Chip materials & memory

2D memristors · thin-film growth
2025Giant memory window performance and low power consumption of hexagonal boron nitride monolayer atomristorChips & memorynpj 2D Materials and Applications

S. J. Yang, Y. R. Jeon, D. Kim, S. Mohan, S. Kutagulla, M. Disiena, S. K. Banerjee, et al.

Why it matters

Shows that a single layer of boron nitride can work as a memory cell with a large gap between its on and off states and low switching power. Both are key for dense, energy-efficient memory.

2024Reliability improvement and effective switching layer model of thin-film MoS₂ memristorsChips & memoryAdvanced Functional Materials

Y. Huang, Y. Gu, S. Mohan, A. Dolocan, N. D. Ignacio, S. Kutagulla, et al.

Why it matters

Reliability is what keeps 2D memristors out of real products. This work makes MoS₂ devices switch more consistently and proposes a model for which part of the film actually does the switching.

2024Volatile and nonvolatile resistive switching coexistence in conductive point hexagonal boron nitride monolayerChips & memoryACS Nano

S. J. Yang, L. Liang, Y. Lee, Y. Gu, J. Fatheema, S. Kutagulla, D. Kim, M. Kim, et al.

Why it matters

Finds that one boron nitride monolayer device can show both short-term and long-term memory. The same material could then act like both a synapse and a storage cell in brain-inspired hardware.

2024Programmable retention characteristics in MoS₂-based atomristors for neuromorphic and reservoir computing systemsChips & memoryACS Nano

Y. Lee, Y. Huang, Y. F. Chang, S. J. Yang, N. D. Ignacio, S. Kutagulla, S. Mohan, et al.

Why it matters

Neuromorphic and reservoir computing need memory that fades on a schedule. This work shows how long MoS₂ atomristors hold their state can be tuned to fit.

2023Comparative study between sulfurized MoS₂ from molybdenum and molybdenum trioxide precursors for thin-film device applicationsChips & memoryACS Applied Materials & Interfaces

S. Fatima, Y. Gu, S. J. Yang, S. Kutagulla, S. Rizwan, D. Akinwande

Why it matters

Sulfurizing a deposited metal or oxide layer is a fab-friendly way to make MoS₂. This compares the two starting materials and shows how the choice shapes film quality for devices.

2023Direct metal-free growth and dry separation of bilayer graphene on sapphireChips & memoryACS Applied Nano Materials

S. Mohan, D. Kireev, S. Kutagulla, N. Ignacio, Y. Gu, H. Celio, X. Zhan, et al.

Why it matters

Graphene is usually grown on metal and moved with wet chemistry, which leaves contamination that hurts electronics. Growing it straight on sapphire and peeling it off dry avoids both steps.

2021In situ monitoring of composition and sensitivity to growth parameters of pulsed laser depositionChips & memoryACS Applied Electronic Materials

T. Orvis, H. Kumarasubramanian, M. Surendran, S. Kutagulla, A. Cunniff, et al.

Why it matters

Tracks film composition in real time during laser deposition and maps how sensitive it is to growth settings. It's a step toward deposition that's controlled by feedback instead of trial and error.

Bioelectronics

2D materials meet biology
2026Biocompatibility of large-area two-dimensional electronic materials with neural stem cellsBioelectronicsCell Reports Physical Science

R. T. Jayanth, R. Duquette, S. Kutagulla, S. P. Salazar, E. Okogbue, J. Zhou, et al.

Why it matters

Before 2D electronics can be used in brain interfaces or implants, they have to be safe for the cells around them. This tests large-area 2D films directly with neural stem cells.

2024Atomically thin bioelectronicsBioelectronicsNature Reviews Materials

D. Kireev, S. Kutagulla, J. Hong, M. N. Wilson, M. Ramezani, D. Kuzum, et al.

Why it matters

A perspective on how atom-thin materials could make bioelectronics thinner, softer and better at conforming to the body, covering sensing and stimulation and the challenges still in the way.

Physical chemistry

Undergraduate research
2018The influence of aqueous solvent on the electronic structure and non-adiabatic dynamics of indole explored by liquid-jet photoelectron spectroscopyPhysical chemistryFaraday Discussions

G. Kumar, A. Roy, R. S. McMullen, S. Kutagulla, S. E. Bradforth

Why it matters

Indole is the light-absorbing part of the amino acid tryptophan. This study measures how surrounding water changes its electronic structure and what happens after it absorbs light.
