Roles of grain boundaries in cleavage cracking and thermal crack arrest experiments in iron-silicon alloy
(Massachusetts Institute of Technology, 2002)
High-angle grain boundaries in steel offer an important resistance to the propagation of cleavage cracks that affects the fracture toughness and can modulate the ductile-to-brittle transition temperature of fracture downward. ...
Finite element analysis of shells with layers
(Massachusetts Institute of Technology, 2002)
It is well established that thin shell structures frequently feature narrow bands of strain concentration and localized displacement irregularities referred to as boundary and internal layers. It is crucial to capture these ...
Time-frequency variations in cerebellar intention tremor and prediction of drug response limb loading resulted results
(Massachusetts Institute of Technology, 1995)
Photo-electroforming, a new manufacturing process for micro-electro-mechanical systems
(Massachusetts Institute of Technology, 1995)
A perturbation/correlation approach to force-guided robot control
(Massachusetts Institute of Technology, 1996)
Cell-seeded type II collagen scaffolds for articular cartilage tissue engineering
(Massachusetts Institute of Technology, 2007)
Defects in articular cartilage exhibit little spontaneous healing response, in part due to the limited number of chondrocytes available to infiltrate the defect and the absence of a provisional fibrin scaffold to accommodate ...
Development of a microfabricated turbine-driven air bearing rig
(Massachusetts Institute of Technology, 1999)
A team at MIT has been working to develop the technology for a micro gas turbine generator that is capable of converting chemical energy from fuel into electrical power. Such a MEMS device would represent a big leap in ...
Materials characterization and structural design of ceramic micro turbomachinery
(Massachusetts Institute of Technology, 1999)
Since 1995, MIT has been developing the technology for micro-gas turbine-generators capable of producing 50 W of electrical power in a package less than one cubic centimeter in volume. The initial goal of this project is ...
The development of a proff of principle superfluid Joule-Thomson refrigerator for cooling below 1 Kelvin
(Massachusetts Institute of Technology, 2005)
A new type of sub-Kelvin refrigerator, the superfluid Joule-Thomson refrigerator, has been developed and its performance has been experimentally verified. This refrigerator uses a liquid superfluid mixture of He and 4He ...
Structure and formation of β-sheet fibers
(Massachusetts Institute of Technology, 2003)
The spontaneous organization of protein monomers into fibers, bundles and networks is central to biology. Inspired by the repetitive patterns found in the amino acid sequence of natural fibrous proteins, short peptides ...
