Rate dependent rupture of solid-supported phospholipid bilayers.
(Massachusetts Institute of Technology, 2006)An experimental study on solid-supported phospholipid bilayers was performed in order to investigate rate-dependent behavior of force and probability of bilayer rupture. 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine ... -
Rational control of hydrothermal nanowire synthesis and its applications
(Massachusetts Institute of Technology, 2010)Hydrothermal nanowire synthesis is a rapidly emerging nanowire discipline that enables low temperature growth and batch process. It has a major impact on the development of novel energy conversion devices, high density ... -
Rational design strategies for oxide oxygen evolution electrocatalysts
(Massachusetts Institute of Technology, 2016)Understanding and mastering the kinetics of oxygen electrocatalysis is instrumental to enabling solar fuels, fuel cells, electrolyzers, and metal-air batteries. Non-precious transition metal oxides show promise as ... -
Re-strengthening demineralized bone via tannin-iron crosslinking
(Massachusetts Institute of Technology, 2019)As the world population continues to age, the social and economic impacts resulting from osteoporosis will continue to rise. New treatments for the disease are needed now more than ever. Using tannin iron complexes we show ... -
Reactions of Na2SO4(l) and CoSo4-Na2SO4(l) with SO3(g) and Al2O3(s), 900 - 1250 K
(Massachusetts Institute of Technology, 1988) -
Reactive infiltration processing and compression creep of NiAl and NiAl composites
(Massachusetts Institute of Technology, 1998)Reactive infiltration processing of bulk and composite NiAl was investigated with powder and wire preforms of nickel. Inhomogeneous microstructures were often obtained with powder preforms because their high surface-to-volume ... -
Recycling production designs : the value of coordination and flexibility in aluminum recycling operations
(Massachusetts Institute of Technology, 2013)The growing motivation for aluminum recycling has prompted interest in recycling alternative and more challenging secondary materials. The nature of these alternative secondary materials necessitates the development of an ... -
Red emitting photonic devices using InGaP/InGaAlP material system
(Massachusetts Institute of Technology, 2005)In this thesis, two red emitting photonic devices are presented using the InGaP/InGaAlP material system. InGaP/InGaAlP material system provides large flexibility in the band gap energy while being lattice matched to GaAs ... -
Redefining manufacturing quality control in the electronics industry
(Massachusetts Institute of Technology, 2000)The most time consuming and capital intensive portion in the assembly of power electronic devices is the test system. A comprehensive test system including functional and stress screening technologies can significantly ... -
Reducing inventory and order delivery time in an internal extended value chain
(Massachusetts Institute of Technology, 2005)The extended value stream for the ABB Power Technologies Medium Voltage Business Area consists of numerous factories situated across various different countries. Most of these facilities were originally acquired by ABB to ... -
Reducing recombination in organic photovoltaics
(Massachusetts Institute of Technology, 2011)In this thesis, I consider two methods to improve organic photovoltaic efficiency: energy level cascades and promotion of triplet state excitons. The former relies on a thin layer of material placed between the active ... -
Reducing the cost of quality (COQ) through increased product reliability and reduced process variability
(Massachusetts Institute of Technology, 2004)Today, Dell, Inc. (Dell) spends millions of dollars each year to prevent product defects from reaching the end customer and to manage those product defects that have escaped to the end customer. The cost of the equipment, ... -
Reduction of rework at a large aerospace manufacturer
(Massachusetts Institute of Technology, 2012)It is an axiom of the manufacturing of any complex product that errors will occur that require repair or discard of said product. In building aircraft, Raptor Aerospace encounters and repairs numerous deviations from the ...
