Vapor-liquid-solid (VLS) growth of lead chalcogenide thin films for infrared sensing applications
(Massachusetts Institute of Technology, 2018)Infrared sensors are used in a variety of applications, from gas and moisture analysers, to human body detection to spectrophotometers. Available IR technology falls on two ends of the spectrum: state-of-art photon detectors ... -
Variation of electrical resistance in superelastic NiTi for sensor applications
(Massachusetts Institute of Technology, 2008)Nickel-Titanium (NiTi) is a most commonly known as a heat-activated shape memory alloy. However, the material sometimes displays a constant-temperature property called "superelasticity." A superelastic material is one which ... -
Variation reduction in a wafer fabrication line through inspection optimization
(Massachusetts Institute of Technology, 1997) -
Variation reduction of a closed-loop precision ceramic micromachining process
(Massachusetts Institute of Technology, 1996)This report details the investigation of the micromachining of a TiC.A1203 ceramic using a closed-loop lapping process. Currently the micromachining process laps a ceramic bar with only a priori flatness adjustment. Bar ... -
Variations in grain boundary segregation for nanocrystalline stability and strength
(Massachusetts Institute of Technology, 2012)In the last few decades, nanocrystalline metals have been of increasing interest. Their ability to show increased yield strength and uniform structure show them to be potentially useful in many applications. Additionally, ... -
Versatility of M13 bacteriophage in medicine : vaccine storage and cancer diagnostics
(Massachusetts Institute of Technology, 2007)Two novel ways of engineering the filamentous bacteriophage, M13, for the prevention, diagnosis, and treatment of human disease are proposed. Both ways are founded on the unique structural properties of the M13 bacteriophage ... -

Virus constructed iron phosphate lithium ion batteries in unmanned aircraft systems
(Massachusetts Institute of Technology, 2010)Since lithium ion batteries first became commercially available in 1991, they have been repeatedly improved, continually redefining just how much we can do with electronic devices. Today, battery powered Unmanned Aerial ... -
Virus-based 3-dimensional nanowire network copper and nickel electrodes
(Massachusetts Institute of Technology, 2011)Synthesizing a scalable microelectrode at room temperature is possible using bio-templating. To create a novel 3D electrode, we report M13 virus cross-linking and nickel and copper nanowire synthesis. In this process, virus ... -
Virus-enabled synthesis and 2D/3D assembly of nanowire networks
(Massachusetts Institute of Technology, 2013)Dense networks of high aspect ratio nanowires can provide important functionality to electronic devices through a unique combination of electronic and structural properties including high conductivity, high surface area, ... -
Virus-enabled synthesis of titanium oxide nanowires
(Massachusetts Institute of Technology, 2006)Bio-assisted materials fabrication methods allow for the production of high technology materials and devices at lower costs and with less environmental impact. To expand the biological toolkit for synthesizing materials, ... -
Viscous flow and volume relaxation in simple glass-forming liquids.
(Massachusetts Institute of Technology, 1969) -
Voltage programmable materials
(Massachusetts Institute of Technology, 2015)The physical and chemical properties of nanoscale materials derive largely from structure and composition at interfaces. The possibility to electrically modify these interfacial characteristics would provide a powerful ... -
Wafer surface cleaning for silicon homoepitaxy with and without ECR hydrogen plasma exposure
(Massachusetts Institute of Technology, 1994) -
Water modeling the solid oxide membrane electrolysis with rotating cathode process
(Massachusetts Institute of Technology, 2004)The Kroll process for refining titanium is an expensive batch process which produces a final product that still requires intensive post processing to create usable titanium. A new process, Solid Oxide Membrane Electrolysis ... -
Welded repair and maintenance in the space environment
