Experimental determination of cell adhesion and proliferation response to substrata thickness
(Massachusetts Institute of Technology, 2008)
Controlling cell behavior has been a primary goal for scientists, and physical interactions, specifically cell-surface interactions, have the potential to be a robust system for cell control. Much research has been conducted ...
Microstructural study of two-phase marbles in simple shear
(Massachusetts Institute of Technology, 2009)
Microstructural and textural observations have been conducted on synthetic calcite with 20 wt% quartz deformed in simple shear using transmission electron microscopy and selected-area diffraction. The marbles were deformed ...
Implementing novel inventory controls and weighing the costs and benefits of supplier managed inventory (SMI) in a consolidated manufacturing center
(Massachusetts Institute of Technology, 2006)
The Largo manufacturing site of the Raytheon Company is a pure production facility with limited collocated design capabilities. All of the initial design and development engineering is done in four external sites - ...
Characterization of anodic bonding
(Massachusetts Institute of Technology, 2004)
Anodic bonding is a common process used in MicroElectroMechanical Systems (MEMS) device fabrication and packaging. Polycrystalline chemical vapor deposited (CVD) silicon carbide (SiC) is emerging as a new MEMS device and ...
Substrate and channel engineering for improving performance of strained-SiGe MOSFETs
(Massachusetts Institute of Technology, 2006)
With VLSI technology moving closer towards fundamental physical limits, a way to further improve the transistor drive current for superior circuit performance is enhancing the average velocity of carriers in the channel. ...
Gene-supplemented collagen-glycosaminoglycan scaffolds for nonviral gene delivery in articular cartilage tissue engineering
(Massachusetts Institute of Technology, 2006)
Three-dimensional scaffolds and growth factors have been shown to be important for articular cartilage tissue engineering. A major problem in using recombinant proteins in vivo, however, is the inability to maintain ...
Nanoscale influences on bioactivity : ultrastructure and nanomechanics of model bioactive hydroxyapatite based biomaterials
(Massachusetts Institute of Technology, 2006)
There is a significant need for improved synthetic materials as orthopedic implants to replace human bone lost and damaged due to disease or injury. Certain ceramics, such as hydroxyapatite (HA), have the special property ...
Process and design techniques for low loss integrated silicon photonics
(Massachusetts Institute of Technology, 2006)
Microprocessors have truly revolutionized the efficiency of the world due to the high-volume and low-cost of complimentary metal oxide semiconductor (CMOS) process technology. However, the traditional scaling methods by ...
Grain size control and microstructural evolution in nanocrystalline Ni-W alloys
(Massachusetts Institute of Technology, 2007)
Nanocrystalline materials have been studied extensively over the past two decades because of their useful and interesting physical properties. In most cases, these properties derive from the fine characteristic length scale ...
Critical thickness in silicone thermosets
(Massachusetts Institute of Technology, 2005)
Critical thickness effects are utilized to achieve high fracture toughness in brittle polymers. The postulate of critical thickness, which is: "Macroscopically brittle polymers deform in a ductile fashion below a critical ...
