Nanomaterials for Energy
- Principal Investigators:Linda Helen Doerrer, Bennett Goldberg, Mark Grinstaff, Catherine Klapperich, Pritiraj Mohanty, Anna Swan and Joyce Wong
Nanomaterials are playing a critical role in many areas of technology development for energy. At Boston University, we have a set of efforts that are focused on next generation nanomaterials for the area of oil and gas exploration and discovery, supported by the Advanced Energy Consortium. In particular, the industry recognizes that the chemical and physical properties of reservoir fluids and rocks beyond the wellbore, the three dimensional distribution of reservoir fluids and rocks, and the dynamic paths of fluids are areas in which nanomaterials will play a crucial role.
Research Areas
- Boston University faculty are working with graphene, a single atom thick membrane of carbon from graphite, to develop a novel coating impervious to the harsh environments in deep borehole. Graphene is also being explored as a membrane to make nanoscale pressure sensors, capable of enormous pressure differences without rupture.
- Powering sensors and autonomous micromachines will require nano- and micro-scale power sources, Boston University faculty are working to develop a new class of Li-ion networks embedded in a polymer matrix that could be used for micron-scale batteries.
- To illuminate the properties of the oil fields beyond the bore hole, Boston University faculty are developing new nanomaterials that include a magnetic core surrounded by a coating with functional sensitivity to pH, reactivity with various chemicals, and hydrophobicity and hydrophilicity. Such nanoparticles can be imaged by MRI and track fluid interfaces.
- Additional efforts include novel MEMS devices in high temperature materials being developed by Boston University faculty, and multiplexed nanowire sensors.
Nanophotonics for Solar Energy
Boston University is supporting several efforts in the area of nanophotonics for solar energy. Our focus is on functional nanomaterials that improve efficiency through novel mechanisms, but that can be produced cheaply and in large enough scale to affect real change.
Research Areas
- Boston University faculty are developing carbon nanotubes for energy efficient window coatings.
- Faculty are developing nanoparticles to place in solar cell coatings to compress and shift the solar spectrum to match the absorption properties of solar cells.
- Metal nanoparticles to use plasmon enhancement to improve efficiency are currently in development by Boston University Faculty.
- Boston University faculty are also developing nanopillars of dielectrics to enhance coupling into silicon nanocrystals.
- Silicon-based nanoscale solar cells are yet another renewable resource mechanism being developed by faculty at Boston University.
