Hierarchical layered-silicate-- lamellar triblock copolymer nanocomposites
(Massachusetts Institute of Technology, 2003)The fundamental role of the layered-silicates in a styrene-butadiene-styrene triblock copolymer (SBS) as a function of layered-silicate dispersion during deformation was investigated. Predominantly immiscible composites ... -
Hierarchical mechanics of functional amyloid protein based materials
(Massachusetts Institute of Technology, 2015)Amyloid and amyloid-like proteins are a broad class of misfolded protein structures known for their their roles in a variety of neurodegenerative diseases, but also for their impressive mechanical properties and their ... -
High Deviatoric Strain Engineering/
(Massachusetts Institute of Technology, 2015)The structure of a material can be tuned reversibly or irreversibly by imposing elastic or inelastic strain, leading to change of properties. This defines the concept of strain engineering, which includes both elastic ... -
High efficiency thin film silicon solar cells with novel light trapping : principle, design and processing
(Massachusetts Institute of Technology, 2008)One major efficiency limiting factor in thin film solar cells is weak absorption of long wavelength photons due to the limited optical path length imposed by the thin film thickness. This is especially severe in Si because ... -
High fracture toughness and high modules silicone resins
(Massachusetts Institute of Technology, 2000)Rigid silicone resins, generally referred to as polyalkylsilsesquioxanes, are an important class of hybrid thermosetting polymers with both inorganic and organic characteristics. They have superior thermal stability, heat ... -
High index contrast platform for silicon photonics
(Massachusetts Institute of Technology, 2004)This thesis focuses on silicon-based high index contrast (HIC) photonics. In addition to mature fiber optics or low index contrast (LIC) platform, which is often referred to as Planar Lightwave Cirrcuit (PLC) or Silica ... -
