Energy-Related Research Projects for summer 2017

Sigrid Adriaenssens, CEE

During operation, buildings use as much as 41% of all energy consumed in the US. Since current adaptive building skins generate operational energy savings on the order of 50%, in hot and moderate climates, the potential for energy demand reduction by implementing adaptive skins is significant. The proposed project seeks to develop a digital methodology to predict the solar and mechanical behavior of bimetal adaptive façade elements. This project will be carried out in collaboration with designer and artist Prof. Doris Kim Sung (DOSU-Architecture). Sophomore or junior with a civil, environmental, mechanical or architecture background preferred.

Bamboo, like wood, is a natural composite material with a high strength-to-weight ratio useful for the construction of buildings and bridges in regions with rapidly developing economies. The objective of this research project is to determine and optimize the efficiency of structural bamboo connections. The student will also explore the engineering design of a bamboo hypar-grid shell system intended as a bus shelter canopy.

Metabolic Engineering for the production of renewable fuels and chemicals – Metabolic engineering involves the genetic engineering of organisms to rewire their metabolism for the production of compounds of interest. In our lab we focus on metabolic engineering of different yeast species, using cutting edge technologies in molecular biology. Multiple projects are available in this area, including for the sustainable production of biofuels, bioplastics, chemicals, and drugs.

Synthetic Biology for cellular control – Synthetic biology combines molecular biology, genetic engineering, directed evolution, biophysics, computational biology, and protein engineering with the aim to generate synthetic phenotypes. There are several projects available to use synthetic biology to develop biosensors, genetic circuits, and enzyme control, which will allow us to accelerate strain development, control engineered metabolic pathways, and optimize engineered strains.

Mitochondrial engineering – This project involves engineering yeast mitochondrial physiology to enhance metabolic pathways targeted to this organelle. Several projects are available to target mitochondrial fusion, fission, biogenesis, and mitophagy to study mitochondrial physiology, facilitate mitochondrial engineering, and develop synthetic organelles.

Carbon Neutral Methods for Ammonia Synthesis and Oxidation – The synthesis of ammonia from its elements, N2 and H2, and the reverse reaction, the oxidation of NH3 to dinitrogen and dihydrogen are chemical transformations that are key for carbon neutrality. The industrial Haber-Basch industrial ammonia synthesis relies on methane-derived hydrogen, generates considerable CO2 pollution and inspires the search for alternative methods compatible with renewable H2. Our research group is exploring proton coupled electron transfer (PCET) methods as a pathway for N-H bond formation and scission. Measurement of N-H bond dissociation free energies (BDFEs) of coordinated nitrogen ligands (amides, imides, hydrazides, and ammonia) accompany our approach and guides rational design of transition metal complexes and optimization of ligands to attenuate redox potentials and N-H acidity. As described in the references given below, we have devised methods to rationally control the strengths of N-H bonds in coordinated ammonia to either synthesize NH3 or release H2 from coordinated ammines. Students involved in the project will synthesize new transition metal compounds, conduct state-of-the-art bond strength calculations and make physical methods for measuring N-H bond strengths.

Yiguang Ju, MAE

Biofuel Screening Using Micro Cool Flames – A lot of biofuels have been proposed but are difficult to be tested in engines because of the test costs and amount of fuels needed. This project will develop a micro cool flame reactor to screen the reactivity of biofuels with small quantities. The undergraduate student will work with a graduate student for this project.

Bruce Koel, CBE

Photoelectrochemistry at Modified Hematite (α-Fe2O3) Surfaces for Production of Renewable Hydrogen – This project involves research and development of new hematite (α-Fe2O3)-based photoelectrocatalysts for water splitting to generate renewable H2. Students working on the project will gain experience in synthesis of oxide nanomaterials and deposition of oxide thin films, characterizing these materials, and operating a three-electrode photoelectrochemical (PEC) cell to evaluate their performance. Surface-bound intermediates, as well as their thermal stabilities in the dark and illuminated conditions, will be characterized using in-situ and operando FTIR studies.

Generation of Fuels From Cold Plasma Catalysis of Natural Gas – We study the direct conversion of methane to chemical fuels using a non-equilibrium (cold) plasma generated by a dielectric barrier discharge in combination with a heterogeneous catalyst system. Students working on the project will gain experience in heterogeneous catalysis, synthesis of supported catalysts, plasma processes, and use of gas chromatography.

Hydrogen Uptake and Retention in Li Films for Plasma-Materials Interactions – This project uses surface science instrumentation to obtain quantitative measurements on hydrogen uptake and retention and to elucidate surface chemistry that affects the use of Li coatings on metal (Mo, W) plasma-facing components (PFCs) in high power fusion energy devices. A focus is improve our understanding of chemical erosion (chemical sputtering) and other ion-surface interactions at low incident ion energies as low as 1 eV. This research will take place at the Princeton Plasma Physics Laboratory (PPPL).

Modeling the Prospective Decarbonization of the U.S. Power Grid Using Advanced Generation & Storage Technologies – In collaboration with power producer NRG, ACEE’s Energy Systems Analysis Group (ESAG) is building a model of the U.S. electricity grid to study the prospects for deep decarbonization under high levels of intermittent renewable electricity (IRE). What is the potential role of novel low-carbon generation & storage technologies? Help us discover which policies and advanced technologies will guide the U.S. along the most favorable/least costly decarbonization pathway(s) so that we can meet the aggressive 2050 greenhouse gas emission targets recently agreed to in Paris.

Intern roles, responsibilities, and opportunities:
The intern will assist with

  • research into performance and cost of advanced low-carbon power generation, including wind and solar IRE, and storage technologies and developing simplified representations of these for use in grid modeling;
  • researching current technologies comprising – and policies governing – an actual power grid, e.g. PJM ISO and developing simplified forms that will serve as the grid model’s initial conditions and operating “rules” that govern economic dispatch competition;
  • running the grid model over time, using different assumptions about IRE growth and carbon mitigation policies, to discover if decarbonization occurs, how long it takes, and at what cost to society; and 4) diagnosing failures in the design of current wholesale power markets and incentives for low carbon technologies and propose and assess the efficacy of potential new technologies and policies.

Denise Mauzerall, CEE/WWS

Natural gas is considered a cleaner fossil fuel than coal, but the benefits of using natural gas as a way to reduce emissions of carbon dioxide and hence protect climate could be greatly reduced as a result of methane leakage during extraction, collection, transmission and distribution. Methane is a strong greenhouse gas and a chemical precursor of surface ozone. Since the nineteenth century, oil and gas production companies have halted production at wells when they become economically unviable. Although some wells are plugged, others are simply abandoned. Some of these abandoned wells have been observed to emit significant quantities of methane. Our research group will be working to measure fugitive methane emissions from historic oil and gas fields using novel approaches in remote locations. We will then scale-up to state and national-scale to estimate the potential long-term climate impacts of natural gas extraction.

Forrest Meggers, ARC/ACEE

Novel building system prototyping: The CHAOS lab is looking for an undergraduate research assistant to help with experimental setups for building system prototypes and experimental setups involving novel desiccant dehumidification and latent heat exchange systems. The prototyping will involve 3D printing fabrication techniques, and usage of sensors for data collection and analysis. Another aspect will be surveying ventilation systems on Princeton campus as part of Campus as a Lab using Internet of Things sensors. Previous students have also contributed to and been co-authors of academic publications.

Michael Mueller, MAE

Alternative Fuel-Sensitive Combustion Modeling – When new alternative bio-derived or synthetic fuels are developed, these must be “certified” before they can be used in automotive or aviation engines. Experimental certification in a real engine can be very expensive and requires large quantities of the new fuel, which may be extremely expensive to produce initially. Computational certification using numerical simulations could be used as a more economical fuel screening tool, but models are required that are sensitive to variations in fuel composition. Our group has recently developed a new modeling approach for such fuel sensitivity, and this project will involve performing numerical simulations of turbulent combustion to validate this new approach.

Catherine Peters, CEE (2 available projects)

Carbon capture and storage (CCS) is a climate change mitigation technology that has been cited as essential to meet international climate targets. To manage the safe storage of carbon dioxide in deep subsurface aquifers, the risk of leakage of carbon dioxide from these aquifers needs to be understood and represented in policies. This project aims to investigate how the leakage of subsurface fluids in CCS environments affects rock fractures and resultant leakage using experimental and modeling techniques.

Investigate the effects of solution chemistry on the removal of hazardous metals from wastewater generated by hydraulic fracturing of shales. Will use analytical chemistry methods (ICP-MS, IC) and imaging (SEM, TEM, XRD) to analyze removal by chemical precipitation in batch experiments. Help develop a model of the reaction and compare to experimental results.

Barry Rand, ELE/ACEE

Toward Biodegradable, Non-toxic Computing Systems – Electronic, or e-waste, is a major issue that has considerable environmental impacts owing to heavy metals and other toxic components. This summer research project deals with developing processes that are amenable to electronic circuits and systems that degrade in time and return to the environment without deleterious effects. In particular, we are interested in developing self-assembled monolayers, or SAMs, on an insulating layer of Al2O3 to enhance the mobility and uniformity of pentacene transistors. This project will be experimental in nature and involve solution processing, microscopy, and transistor characterization.

Alexander Smits, MAE

We research a new device for generating power from the wind that couples a piezoelectric element to a Helmholtz resonator. These resonators can generate up to 6 W/m^2 of available energy, exceeding the performance of wind turbine farms. We envision these resonators can be used as an alternative energy source for small- and large-scale power needs, such as powering remote sensors, providing the energy needs of a single house, augmenting local energy needs by mounting them of the roofs of buildings in city environments, or using them in large arrays to enhance the power density of conventional wind farms.

Howard Stone, MAE
