Cycle 20 awards: Ushering in a new year of innovation

Eight new research projects have been selected for funding by the Energy Center in its twentieth annual grant competition. The funding started on January 1, 2026. The overall goal of the Nebraska Center for Energy Sciences Research (NCESR) is to foster research and education in energy sciences by providing funding to support innovative research and collaboration among UNL faculty and other public and private-sector organizations and businesses.

Enhanced Energy Storage using Antiferroelectric Hafnia-Based Dielectrics

Co-Principal Investigator (Co-PI) – Dr. Xiaoshan Xu, professor of physics & astronomy, College of Arts and Sciences

Abstract – With the global push towards renewable energy, there is a growing demand for efficient, high-density, and scalable energy storage technologies. Traditional dielectric capacitors face limitations in energy density and scalability. Antiferroelectric (AFE) hafnia (HfO₂)-based materials have recently gained attention for their high dielectric breakdown strength, excellent scalability, compatibility with Si-based fabrication processes (CMOS), and field-induced phase transitions that enable high energy storage densities. However, critical challenges remain in understanding their AFE phase stability and enhancing the energy storage performance.

The goal of this project is to develop AFE hafnia thin films with enhanced recoverable energy density. This goal will be achieved by pursuing several inter-related objectives aimed at (1) identifying the processing conditions, chemical dopants and electrode materials optimal for stabilization of the AFE phase; (2) conducting accelerated energy performance testing of hafnia capacitors under varying temperatures, frequencies, and electric field strengths to optimize the field-induced phase transition characteristics; (3) boosting the energy storage capabilities by reducing the leakage currents, enhancing the retention characteristics and benchmarking their performance against commercial dielectric materials.

Employment of AFE hafnia will result in disruptive innovation in the energy storage technology due to the drastically enhanced energy density as well as hafnia compatibility with CMOS technology, which enables hafnia integration both into microelectronic packaging and local energy supply systems.

Success of this project will enable development of resilient energy storage systems that would allow coping with the ever-growing energy consumption. Successful project implementation will provide a basis for attracting new funding from federal agencies (NSF, DARPA, NREL, DOE) and from semiconductor companies involved in development of energy storage technologies (Intel, Fluence, Matsushita, Siemens Energy). Both PIs have a strong track record of industry collaboration (Intel, Seagate, Toshiba, Fujitsu), which demonstrates their technical expertise and ability to deliver impactful results.

Principal Investigator (PI) – Dr. Galen E. Erickson, Nebraska Cattle Industry professor of animal science & beef feedlot extension specialist, Institute of Agriculture and Natural Resources

Co-Principal Investigator (Co-PI) – Dr. Jim MacDonald, professor of animal science and graduate committee chair, Institute of Agriculture and Natural Resources

Abstract – Cattle are commonly fed urea that microbes in the rumen convert to protein for the animal. The trade-off to using urea in feedlot diets is the negative impact of energy inputs required for manufacturing urea. This project will evaluate feeding urea to finishing cattle compared to natural protein sources originating from soybean or corn production. There is a strong indication that soybean production will increase due to demand for renewable diesel which will lead to a greater supply of soybean meal. Likewise, distillers grains may become more readily available and economical for cattle as non-ruminants displace distillers grains use with soybean meal. The cattle feeding experiment (year 1) will compare these protein sources for cattle productivity and carcass/meat characteristics, which allows for robust economic modeling in year two. In addition, a novel circularity model will be developed to evaluate the impact of diet ingredient choices and other management inputs on energy utilization, nutrient conservation, and economic dynamics resulting from byproduct utilization in integrated cropping-beef systems typical of Nebraska. We hypothesize that these opportunities are greatest in Nebraska where cropping and beef production are already aligned in many ways. Specifically, this project will work toward eliminating N inputs that are energy intense while enhancing bio-byproducts use in cattle feeding operations. Improving natural resource use by using byproducts for cattle production is a staple in Nebraska but we have not quantified the ‘circularity’ benefits or evaluated the energy balance of replacing urea. Quantifying these impacts is a critical outcome of this project and will allow us to expand on circularity of cropping-beef systems for things such as manure digestion, different housing systems to conserve nitrogen, precision manure nitrogen management, and others. This funding will provide baseline data to attract extramural funding in the future.

Principal Investigator (PI) – Dr. Robert Streubel, assistant professor of physics & astronomy, College of Arts and Sciences

Co-Principal Investigator (Co-PI) – Dr. Peter A. Dowben, Charles Bessey Professor of Physics, College of Arts and Sciences

Abstract – The goal is to develop solid-state neutron and alpha voltaics, which provide both direct electric power generation and neutron radiation shielding at low cost using hydrogenated boron carbide semiconductors. A neutron voltaic creates voltage and current pulses from neutron absorption, much like a photovoltaic. Designing and testing a combined neutron and alpha voltaic device with efficient radiation capture and charge extraction, for the highest possible power product, requires exploring both diode and transistor geometry. This is because an alpha voltaic will work best in transistor geometry due to small penetration depth of alpha particles. The project exploits the strengths of Robert Streubel in device fabrication and frequency-dependent electronic transport and decades of boron carbide device development at the University of Nebraska. It includes materials synthesis, device integration, radiation testing, and optimization. The investigators seek to establish the foundations for neutron and alpha voltaics research, including the demonstration of significant zero-bias currents under neutron and alpha radiation, to become competitive for funding from the Office of Fusion Energy Sciences (OFES) within the U.S. Department of Energy (DOE) and to position the University of Nebraska for the anticipated Rads to Power (R2W) solicitation (DARPA-SN-25-78) from the Defense Advanced Research Projects Agency (DARPA) Defense Science Office (DSO). The team will refurbish an existing deuterium and tritium (D-T) neutron source, at the University of Nebraska, to offer in-house capabilities for the characterization of neutron and alpha voltaics in the Laboratory of Robert Streubel.

Principal Investigator (PI) – Dr. Yanan (Laura) Wang, assistant professor of electrical and computer engineering, College of Engineering

Co-Principal Investigator (Co-PI) – Dr. Yinsheng Guo, assistant professor of chemistry, College of Arts and Sciences

Abstract – Remarkable progress in artificial intelligence over the past decade has transformed research and industry, driving breakthroughs in data mining, natural language processing, healthcare, finance, autonomous systems, cybersecurity, and more. The dominant AI systems rely on artificial neural networks (ANNs) implemented via software simulations that emulate the behavior of biological neural networks, such as the human brain. These simulations are executed on conventional von Neumann architectures, which increasingly face energy efficiency challenges with the exponential growth of data. The energy required for training and maintaining state-of-the-art AI models, especially large language models and deep learning networks, not only poses economic and environmental challenges but also raises concerns about long-term scalability and sustainability.

Toward next-generation energy-efficient AI technology, the collaborative team will explore an innovative approach that transitions from conventional software-based neural network simulations to physical systems where the neural architecture is directly implemented in hardware. Central to this project is the development of a nonlinear activation layer, a key component of optical neural networks, using the unique exciton-polariton properties of lead halide perovskite (LHP). Known for its large exciton binding energy and strong light-matter coupling, both heterogeneous and monolithic optical cavities will be developed to achieve room-temperature polariton condensation and nonlinear neuromorphic functionality utilizing this emerging quantum material (Years one & two). Built on these polariton platforms, an optical neural network (ONN) will be trained in a reservoir computing (RC) scheme (Year two). The performance of the proposed ONN will be benchmarked through the classification of handwritten digits, serving as a proof-of-concept for broader machine learning applications. This interdisciplinary project will pave the way toward scalable, ultrafast, and energy-efficient AI systems based on novel quantum photonic materials.

Principal Investigator (PI) – Dr. Lucia Fernandez-Ballester, assistant professor of mechanical and materials engineering, College of Engineering

Co-Principal Investigator (Co-PI) – Dr. Craig A. Zuhlke, Richard L. McNeel Associate Professor of Electrical and Computer Engineering, College of Engineering

Abstract – Wind turbine blades are produced by bonding a small number of components with adhesives, but cracking and de-bonding of adhesive joints are major contributors to blade failure. Furthermore, thermoset composites are the typical material of choice for turbine blades, but thermosets cannot be repaired, be welded for joining parts, nor recycled into new blade components. There is currently increasing interest in switching to thermoplastic-based composites, which also exhibit excellent mechanical and stability properties but have potential to enable welding without adhesives, in-situ repairs, and recycling of blade materials. However, the high pressures and temperatures needed to weld thermoplastics are challenging to apply when joining large components, and bonding of thermoplastics to other materials is currently limited by poor adhesion and failure under mild loads. To overcome these challenges, the research objective of this proposal is to develop an innovative method to achieve strong adhesion of thermoplastic polymers through the use of an intermediate, femtosecond laser surface-processed metallic component. Well-controlled micro-and nano-structures will be created to induce superwicking and welding at mild conditions, with geometries tailored to resist the complex mechanical loadings expected during wind turbine service. This research will yield exceptional mechanical performance, decrease manufacturing costs, and allow in-situ repair and recycling of wind turbine blades.

Co-Principal Investigator (Co-PI) – Dr. Ozan Ciftci, Kenneth E. Morrison Distinguished Professor of Food Science & Technology, Biological Systems Engineering, Institute of Agriculture and Natural Resources, College of Engineering

Abstract – This project aims to develop safer, eco-friendly, efficient batteries using Nebraska’s abundant agricultural resources. The team will convert a plant-based material into advanced, safer, cheaper battery components to address key challenges and improve metal-ion battery performances. Such advancements can support efficient, cost-effective energy storage for consumer electronics, electric vehicles and transform grid-scale energy storage.

Principal Investigator (PI) – Dr. Jian Wang, Wilmer J. and Sally L. Hergenrader Presidential Chair of Mechanical and Materials Engineering and graduate chair of materials engineering, College of Engineering

Co-Principal Investigator (Co-PI) – Dr. Bai Cui, professor of mechanical and materials engineering, College of Engineering

Abstract – Center-pivot irrigation systems are critical to agriculture in Nebraska, but a persistent problem is that their steel pipelines often begin leaking after only seven to 10 years of service. The primary cause is corrosion, which results from long-term exposure to water, dissolved minerals, chemicals, temperature changes, and sometimes microorganisms. Recently, pipeline operators have observed that corrosion appears to accelerate after lead was removed from galvanized (zinc-coated) pipes, raising concerns about reduced pipeline lifespan and increased maintenance costs.

Galvanization protects steel by applying a zinc coating that both blocks water from reaching the steel and corrodes sacrificially to protect the underlying metal. Historically, small amounts of lead were added during the galvanizing process because lead improves how well zinc spreads and adheres to steel. However, due to environmental and health concerns, modern standards have largely eliminated lead from galvanized coatings. While this improves safety, it may unintentionally reduce corrosion resistance.

This project aims to understand why galvanized pipes may corrode faster after lead removal and to develop effective, lead-free strategies to improve pipeline durability. The researchers hypothesize that lead indirectly slowed corrosion by improving coating quality and possibly influencing microbial activity on pipe surfaces. Without lead, zinc coatings may be more prone to breakdowns, localized pitting, or attack by corrosion-causing bacteria present in irrigation water.

The study will compare three types of pipelines: uncoated steel, galvanized steel with lead, and galvanized steel without lead. Laboratory corrosion tests will be performed using both purified water and real irrigation water from Nebraska. Based on our findings, the project will work with irrigation companies and utilities to develop practical lead-free solutions. The goal is to extend pipeline service life, reduce repair costs for farmers, protect water quality and strengthen the long-term reliability of Nebraska’s irrigation infrastructure—without reintroducing lead.

Principal Investigator (PI) – Dr. Yongfeng Lu, Lott University Professor of Electrical and Computer Engineering, College of Engineering

Co-Principal Investigator (Co-PI) – Dr. Bai Cui, professor of mechanical and materials engineering, College of Engineering

Abstract – This research aims to improve laser-based nuclear fusion by developing better ways to create and inspect the tiny fuel targets used in experiments, supporting the U.S. Department of Energy’s efforts to advance clean fusion energy. Turning fusion into a practical source of unlimited clean power still faces big hurdles. One key issue is reliably making the precise fuel targets and checking the frozen fuel layer inside them at extremely cold temperatures before the laser shot. To tackle this, the project proposes using two cutting-edge tools: a high-precision 3D printing method called two-photon polymerization to build better targets, and an advanced imaging technique called cryogenic coherent anti-Stokes Raman scattering to create detailed 3D views of the targets and fuel under those freezing conditions.

Cycle 19 research projects secure Year 2 funding

To determine the projects that receive Year 2 funding, the NCESR Progress Review Committee reviewed the Cycle 19 Principal Investigators (PIs) six-month reports, and each PI presented to the committee on October 15, 2025. The review allowed the committee and PIs to discuss the progress of each project in more detail. The Progress Review Committee is comprised of the NCESR Director and Associate Director, NPPD Liaisons and NUtech staff. The committee meeting also allows NUtech to connect with the PIs and Co-PIs, if they haven’t already, regarding disclosures and intellectual property (IP). Following committee deliberations, all five Cycle 19 projects received Year 2 funding, which began on January 1, 2026.

We look forward to receiving future updates regarding their research progress, external funding awards, and any IP results.

Congratulations to the Darrell J. Nelson 2026 Summer Internship Recipients

Enhancing students’ research, critical thinking, and professional communication skills.

For the 13th year, NCESR offered a summer internship opportunity for undergraduate students in energy sciences research. To better align with undergraduate decision timelines, NCESR revised the application process by moving the application deadline and award notification to November–December 2025 instead of February–March 2026. Because many students accept summer internships by the end of December, this earlier timeline allowed undergraduates to apply before committing to other summer opportunities.

Each award recipient receives up to $6,000 to support their research work during the summer of 2026. Faculty sponsors may also request an additional $1,000 in travel funds to assist interns with expenses related to presenting their summer research at a relevant conference.

Interns and their faculty sponsors will participate in a meet-and-greet event in May with the NCESR team and NPPD liaisons. During this session, participants will learn about the work of NCESR and NPPD, as well as the history of NCESR and its summer internship program. Interns will also have the opportunity to share and discuss their research projects with fellow interns and faculty sponsors.

Additional summer activities include a tour of Cooper Nuclear Station, consistently noted by interns as a program highlight, and the presentation of a research poster at the UNL Summer Research Symposium in August 2026, where interns will compete for a $500 award recognizing the best NCESR summer intern poster. At the conclusion of the paid internship, each student will submit a summary report describing their accomplishments and/or research outcomes in energy sciences.

Through the collaboration between the University of Nebraska–Lincoln Summer Research Program (SRP) and NCESR, interns will have the opportunity to participate in seminars, workshops, and social events on the UNL campus, if interested. These activities provide opportunities to connect with students conducting research in other sciences, technology, engineering, and related disciplines and to build friendships with students from across the country.

Transitioning to a sustainable bioeconomy requires converting up to one billion tons of captured and waste carbon into biofuels each year. Methanosarcina is a promising microbial platform that can be engineered to generate renewable methane and bioisoprene fuels from CO2 and waste carbon at low cost at industrial scale. This project aims to design novel enzymes, bioreactors, and Methanosarcina cells to optimize CO2 conversion selectivity to biogas and bioisoprene, a high-value chemical that can be converted to jet fuel or synthetic rubber. Computational modeling and high-throughput enzyme engineering will be used to design and select for novel enzymes that can be used to enhance carbon capture and biofuels synthesis. Plasmids containing modified enzymes have been synthesized and mutant library validation and screening are in process. Engineered cells and biocatalysts will be embedded into soft materials to design and develop robust gas-liquid contactors for biorefining processes. Methods have been developed to synthesize polyvinylidene fluoride (PVDF) and cellulose triacetate (CTA) nanoparticles <200nm in diameter, which will be used to encapsulate enzymes and whole cell catalysts. If successful, the project’s enzymes, materials, and engineered cells are expected to improve carbon capture technologies and enable sustainable biofuel and biomanufacturing in various applications, including for (ethanol) fermentation and biomedical uses. When combined, the novel bioreactors, strains, and enzymes produced have the potential to make a significant impact on converting captured and waste carbon for sustainable aviation and transportation fuel, decarbonizing heavy industry, and reducing greenhouse gas emissions.

Our project, Innovative Approaches to Sustainable Agriculture: Greening Ammonium Sulfate Production, is developing a sustainable pathway to produce ammonium sulfate fertilizer by integrating renewable energy with emission control systems. Leveraging modeling work, we have designed processes where alkaline water electrolyzer generates green hydrogen, which is then fed into a modified Haber–Bosch loop to synthesize green ammonia. This ammonia serves as the reagent in an ammonia-based flue gas desulfurization (FGD) process that captures sulfur dioxide from power plant emissions and converts it into ammonium sulfate fertilizer. During the first reporting period, we achieved significant progress by completing process models for green hydrogen and ammonia production, and initiated detailed modeling of the Efficient Ammonia-Based Desulfurization (EADS) system to target more than 99% SO₂ capture and high ammonia utilization efficiency. By directly linking fertilizer production capacity to Nebraska’s agricultural demand, this approach provides dual benefits: reducing greenhouse gas and sulfur emissions while supplying farmers with a sustainable, locally produced fertilizer. In addition, the project is training graduate and undergraduate students in advanced modeling, techno-economic analysis, and sustainable design, contributing to workforce development in clean energy and agricultural technology.

Over the first six months, they have accomplished fabricating laser-induced periodic surface structures (LIPSS) on nickel substrates to enhance electrocatalytic areas, synthesizing NiCo2O4 powders via hydroxide decomposition and fabricating electrodes through electrophoretic deposition, and conducting initial electrochemical characterizations via cyclic voltammetry and DFT simulations to assess doping effects on OER activity. The team has successfully nanostructured Ni substrates, synthesized NiCo2O4 materials, and identified doping strategies for improved performance.

The increasing presence of artificial intelligence (AI) in everyday life has brought an immediate need for innovative thermal management solutions in AI computing datacenters. The next generation of thermal management solutions will increase the sustainability of AI datacenters by decreasing the environmental impact associated with cooling AI computing components while simultaneously extending their lifetime. With NCESR’s support, we have developed a highly tunable and scalable surface engineering method that can dissipate the thermal loads generated by AI computing components by using waste heat from the components to boil commercially available engineered fluids that can directly interface with AI server racks. The femtosecond laser-based surface processing technique generates microscale structures that are blanketed in nanoparticles on bulk copper blocks. These features, finer than a human hair, promote boiling and lead to remarkably efficient heat transfer, which will keep computing components cool and prevent the need for the inefficient current thermal management solution of air cooling. Since the beginning of NCESR’s support, we have isolated the role of the laser-generated microscale and nanoscale roughness layers for boiling heat transfer, and devised methods to control each layer independently which has opened doors for us to create optimized boiling surfaces for several different thermal loads.

CNS tour creates lasting memories for interns and faculty

Interns and faculty from the Nebraska Center for Energy Sciences Research (NCESR) visited NPPD’s Cooper Nuclear Station (CNS) on July 9 to learn about safe, reliable, emissions-free nuclear energy and how the station has generated it for over fifty years.  

The site tour started with a presentation led by Nuclear Engineer Supervisor Eric Wilke that included the background and history of CNS, how a boiling water reactor generates nuclear power, and the value of existing nuclear power plants and the growing interest in advanced nuclear options. After the presentation, Wilke, Design Engineer Jacob Patrick, and Design Electrical Engineer Steven Thiem escorted the NCESR team to the Protected Area, where they received an interactive demonstration in the Control Room Simulator. While in the Training Building, the tour leaders explained the control rod and fuel bundle mock-up displays and showed the group the Independent Spent Fuel Storage Installation. Additional tour stops included the reactor building’s refuel floor, control room corridor, turbine building, emergency diesel generator and switchyard. The tour concluded with lunch and a question-and-answer session.

In 2024, CNS celebrated fifty years of commercial operation. In those fifty years, CNS generated approximately 275 million MWhs of carbon-free electricity, eliminating emissions of approximately 275 million tons of CO2 into the atmosphere.

In June 1968, NPPD (known as Consumers Public Power District at the time) received permission to begin construction of CNS, using more than 90,000 cubic yards of concrete and 10,000 tons of steel. The plant started commercial operation on July 1, 1974, and its General Electric BWR/4 reactor can generate a nominal 800-MWhs of electricity.

CNS received a license renewal from the Nuclear Regulatory Commission (NRC) in November 2010, extending the operating license to January 2034. NPPD’s board of directors authorized management to pursue a subsequent license renewal that, if approved by the NRC, would extend the operating license to January 2054. Since its inception, CNS has achieved many notable accomplishments. In 1998, it was the first plant in the U.S. to load nuclear fuel containing uranium provided under the Megatons to Megawatts Program. That program, in which uranium removed from nuclear weapons of the former Soviet Union was turned into low-enriched uranium and then into fuel, helped make the world safer and powered Nebraska’s economy.
