Parabolic trough solar collectors : design for increasing efficiency
(Massachusetts Institute of Technology, 2011)
Parabolic trough collectors are a low cost implementation of concentrated solar power technology that focuses incident sunlight onto a tube filled with a heat transfer fluid. The efficiency and cost of the parabolic trough ...
Analytic and numerical study of underwater implosion
(Massachusetts Institute of Technology, 2013)
Underwater implosion, the rapid collapse of a structure caused by external pressure, generates a pressure pulse in the surrounding water that is potentially damaging to adjacent structures or personnel. Understanding the ...
Inverse Monte Carlo simulation of biomolecular conformation and coarse-grained molecular modeling of chondroitin sulfate conformation, titration, and osmotic pressure
(Massachusetts Institute of Technology, 2004)
The first part of this thesis is concerned with the solution structure determination problem. Whereas many biomacromolecules, such as proteins, can be adequately characterized by a single conformation in solution, numerous ...
Peripheral nerve regeneration through tubular devices : a comparison of assays of device effectiveness
(Massachusetts Institute of Technology, 2000)
Peripheral nerve injury affects nearly 200,000 patients annually in the United States and unless treated results in paralysis of skeletal muscle and loss of sensation. Previous studies in this laboratory have focused on ...
Photonic engineering of near- and far-field radiative heat transfer
(Massachusetts Institute of Technology, 2016)
Radiative heat transfer is the process by which two objects exchange thermal energy through the emission and absorption of electromagnetic waves. It is one of nature's key fundamental processes and is ubiquitous in all ...
Mechanisms of reorientation in phytoplankton : fluid shear, surface interactions, and gravitaxis
(Massachusetts Institute of Technology, 2014)
Phytoplankton are a vital part of the ecosystem in oceans and lakes, where they form the base of the food chain and have major global impacts, for example producing 50% of the planet's oxygen. Phytoplankton can also serve ...
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 ...
Predictive design and fabrication of complex micro and nano patterns via wrinkling for scalable and affordable manufacturing
(Massachusetts Institute of Technology, 2014)
There is a demonstrated need for scalable and affordable manufacturing of complex micro and nano scale structures for applications such as fluidics-based medical diagnostics and photonicsbased sensing. Although high-rate ...
Ductile fracture at intermediate stress triaxialities : experimental investigations and micro-mechanical modeling
(Massachusetts Institute of Technology, 2013)
Accurate predictions of the onset of ductile fracture play an increasingly important role in the design of lightweight sheet metal structures. With the development of virtual prototyping practices, most transportation ...
