Ancient engineering : selective ceramic processing in the Middle Balsas Region of Guerrero, Mexico
(Massachusetts Institute of Technology, 2008)
Previous experimental research into ancient pottery production has proven that potters can produce vessels with varying materials properties, such as thermal shock resistance and permeability. These properties are ...
A conjugated polymer plastic gel
(Massachusetts Institute of Technology, 2008)
We present a gel route to process highly oriented conjugated polymer films and fibers. The incorporation of hexafluoroisopropanol, a strong and stable dipolar group, to the polythiophene backbone enhances the solubility ...
Templated self-assembly of nanoporous alumina : pore formation and ordering mechanisms, methodologies, and applications
(Massachusetts Institute of Technology, 2005)
Porous anodic aluminum oxide (AAO), also known as porous alumina, is a self-ordered nanostructured material well-suited for use in electronic, magnetic, optical and biological applications due to its small pore size (4-200nm) ...
Pottery engineering in ancient Guerrero, Mexico : the site of Las Fundiciones
(Massachusetts Institute of Technology, 2007)
This thesis examines ancient pottery from the site of Las Fundiciones, Guerrero, Mexico. Because this site provides the only documented evidence of prehispanic metal smelting in Mesoamerica it is critical to examine artifacts ...
Effects of catalyst pretreatment for carbon nanotube growth
(Massachusetts Institute of Technology, 2007)
The effects of pretreatment of iron catalyst for carbon nanotube (CNT) growth was studied. CNTs were grown on Fe/A1203 (1/10 nm) thin-film catalyst deposited on silicon substrates via exposure to C2H4 in a thermal chemical ...
Temperature effects on the electronic conductivity of single-walled carbon nanotubes
(Massachusetts Institute of Technology, 2007)
The room-temperature electronic conductivity and temperature dependence of conductivity were measured for samples of carbon nanotubes of three types: pristine; functionalized with a nitrobenzene covalent functionalization, ...
Processing factors contributing to growth and decline in the steel industry
(Massachusetts Institute of Technology, 2007)
During the second half of the twentieth century, a technological shift occurred in the steel industry. A different mix of refining and melting furnaces were used, with increasing use being made of basic oxygen and electric ...
Commercialization of bit-patterned media
(Massachusetts Institute of Technology, 2009)
Realm of data storage density has expanded from gigabyte- to terabyte-domain. In such a high areal density, bit-patterned media is a promising candidate to overcome the superparamagnetic limit faced by the conventional ...
Shape memory ceramics in small volumes
(Massachusetts Institute of Technology, 2016)
Shape memory ceramics rely on martensitic transformations which are similar to those found in metallic shape memory materials, but ceramics offer several advantages over metals such as higher operating temperatures and ...
Transformation toughening of [gamma][prime]-strengthened metastable austenitic steels
(Massachusetts Institute of Technology, 1990)
