What is measured is managed : statistical analysis of compositional data towards improved materials recovery
(Massachusetts Institute of Technology, 2015)
As materials consumption increases globally, minimizing the end-of-life impact of solid waste has become a critical challenge. Cost-effective methods of quantifying and tracking municipal solid waste contents and disposal ...
Characterizing hydrogel imposed strain fields on brain tissue phantom for use in neural implant device coatings in presence of micromotion
(Massachusetts Institute of Technology, 2014)
Glial scar tissue forms in the brain as a response to the implant injury and hampers the effectiveness of the implant treatment. Constant relative micromotion between the mechanically mismatched neural implant and brain ...
Production of phosphorus alloys through thermal reactions and electrochemical reduction of molten apatite
(Massachusetts Institute of Technology, 2020)
A process for extracting phosphorus from fluorapatite through high temperature electrochemical means. Theoretical modelling and calculations show that P-alloys can be manufactured directly from decomposed molten fluorapatite. ...
Synthesis of guanidinium-functionalized amphiphiles for the exploration of chaotropic supramolecular nanoribbons
(Massachusetts Institute of Technology, 2021)
Nanoscale self-assembly driven by the hydrophobic effect is of intense research interest due to the ability to synthesize complex, chemically diverse structures with molecular length scales. Supramolecular self-assemblies ...
Simulating and calibrating stretchable optical fibers for studying neural dynamics
(Massachusetts Institute of Technology, 2020)
Study of the central nervous system (CNS) in freely-moving animal behavior experiments is greatly limited by the materials available for neural probing and optical recording, such as silica, which are stiff and can damage ...
Development and research of porous alumina xerogel membranes for electrospray propulsion applications
(Massachusetts Institute of Technology, 2020)
Electrospray engines have been under development at the MIT Space Propulsion Laboratory (SPL) for many years. The operating principle of electrospray engines is a voltage drives a charged liquid fuel through an extractor ...
A more comprehensive life cycle cost analysis of pavement materials alternatives
(Massachusetts Institute of Technology, 2014)
Life Cycle Cost Analysis (LCCA) is a commonly used tool in analyzing the economic viability of highway construction investments. The initial and life-cycle materials costs associated with highway construction involve a ...
Construction of a classification hierarchy for process underspecification to streamline life-cycle assessment
(Massachusetts Institute of Technology, 2014)
Concerns over global warming potential and environmental degradation have created a demand for accurate assessment of the impact of various products and processes. Life cycle assessment (LCA), a quantitative assessment ...
Equilibrium configurations of oxygen bubbles on surfaces for applications in nanostructured hematite electrodes
(Massachusetts Institute of Technology, 2015)
The variability of a nanostructured material's fundamental properties as compared to its bulk state has led to the rich field of nanotechnology and the quest to uncover unique properties of structures at the nanoscale. An ...
Fabrication of nanoscale magnetic domains using block-copolymer lithography
(Massachusetts Institute of Technology, 2014)
The tendency of PS-b-PDMS to phase separate, the tunability of the resulting morphology and the sufficient etch contrast between PS and PDMS makes the block copolymer ideal for creating patterns that can be transferred ...
