Charge-based transport and drug delivery into cartilage for localized treatment of degenerative joint diseases
(Massachusetts Institute of Technology, 2015)
Traumatic joint injuries significantly increase synovial fluid levels of pro-inflammatory cytokines that can initiate cartilage degeneration leading to osteoarthritis (OA). Articular cartilage is a highly negatively charged, ...
Ultrathin crystalline silicon solar cells incorporating advanced light-trapping structures
(Massachusetts Institute of Technology, 2015)
Solar photovoltaics, which convert the energy potential of photons from the sun directly into electrical power, hold immense promise as a cornerstone of a clean energy future. Yet their cost remains greater than that of ...
Ion transport across individual sub-continuum graphene nanopores : phenomenology, theory, and implications for industrial separations
(Massachusetts Institute of Technology, 2015)
Atomically thin materials, and in particular graphene, provide a new class of solid-state nanopores - apertures that allow for the exchange of matter across thin membranes - with the smallest possible volumes of any ion ...
Instantaneous continental-shelf scale sensing of cod with Ocean Acoustic Waveguide Remote Sensing (OAWRS)
(Massachusetts Institute of Technology, 2015)
Reported declines in the population of Atlantic cod have a potential to affect long-term ecological balance and the sustainability of the cod fishery along the US northeast coast. These assessments have led to severe fishing ...
Shipboard integrated engineering plant survivable network optimization
(Massachusetts Institute of Technology, 2015)
Due to the complexity of naval ship systems, and the iterative nature of classical design, the U.S. Navy has struggled to meet the spirit of Cost-as-an-Independent Variable (CAIV) policy. In particular, distinguishing ...
Towards the development of a horizontal ribbon growth process to produce thin, monocrystalline silicon sheets via the stabilization of the (111) plane in undercooled melts
(Massachusetts Institute of Technology, 2015)
A new manufacturing process that directly produces thin, monocrystalline silicon wafers would significantly reduce the cost and energy used to make high efficiency, crystalline-silicon solar panels. Although alternative ...
Edge fracture of AHSS sheets under out-of-plane loading followed by in-plane loading
(Massachusetts Institute of Technology, 2015)
In recent years edge fracture has become a challenge in the manufacturing industry with the dramatical increase in the application of light-weight materials such as Advanced High Strength Steels (AHSS) and aluminum alloys. ...
Ductile fracture after complex loading histories : experimental investigation and constitutive modeling
(Massachusetts Institute of Technology, 2015)
In engineering practice, sheet metal often fails after complex strain paths that deviate substantially from the widely studied proportional loading paths. Different from previous works on the ductile fracture of sheet ...
Defect Engineering in Cuprous Oxide (Cu₂O) Solar Cells
(Massachusetts Institute of Technology, 2015)
This thesis is focused on the development of a cuprous oxide (Cu₂O) thin-film (TF) solar cell that is fabricated by manufacturing-friendly methods such as electro-deposition, sputtering and atomic layer deposition. Due to ...
Observation and manipulation of the wave nature of phonon thermal transport through superlattices
(Massachusetts Institute of Technology, 2015)
As the scale of electronic, photonic, and energy harvesting devices has shrunk, the importance of understanding nanoscale thermal transport has grown. In this thesis, we investigate thermal transport through superlattices ...
