Single-component Li₂O solid electrolyte interphase on lithium : probing transport properties in battery environments
(Massachusetts Institute of Technology, 2020)
Lithium (Li) anodes suffer numerous challenges arising from the chemically inhomogeneous nature of the native solid electrolyte interphase (SEI), which impedes smooth Li plating and leads to dendrite growth. In spite of ...
Numerical simulation of heavy oil droplets mixing in supercritical water at conditions relevant to supercritical water heavy oil upgrading
(Massachusetts Institute of Technology, 2020)
Supercritical water (SCW) crude oil upgrading is a promising technology for upgrading and desulfurization of heavy crude oil and residues. The outcome of this process is determined by an interplay of hydrocarbon cracking ...
Light manipulation with photonic fibers and optical light guides : dynamic structural color and light distribution in microalgae cultures
(Massachusetts Institute of Technology, 2020)
Optical and photonic fibers represent versatile systems for light manipulation. They are used to guide, reflect, emit, and absorb light, and can be designed to alter the light's spectral composition in any of these ...
A universal assistive door unlatching device
(Massachusetts Institute of Technology, 2020)
A seemingly easy task for some, opening doors can cause frustration or pain for many people, due to difficulty spinning or gripping the handle. While technology does exist to make door handles more accessible or easy to ...
Parametric design and performance validation of low-cost, low-pressure drip emitters and irrigation systems
(Massachusetts Institute of Technology, 2020)
This thesis proposes and validates methods to reduce the cost and energy use of drip irrigation systems, with the aim of increasing their adoption among smallholder farmers. By 2050, the growing world population will require ...
Design, construction, and analysis of a modular ship model and open-source autonomous surface vehicle
(Massachusetts Institute of Technology, 2020)
Existing models used to explore hydrostatic, hydrodynamic, seakeeping, and maneuvering characteristics of ships are limited in that their characteristics are essentially static. The effects of various hull appendages, ...
The design, feasibility and cost analysis of sea barrier systems in Norfolk, Virginia and the comparative cost of shoreline barriers
(Massachusetts Institute of Technology, 2020)
Protecting a coastline from the damage of a storm surge, or tidal flooding associated with sea level rise, is a challenging and costly engineering endeavor. Low lying properties located directly on an ocean coastline are ...
A review of the environmental impacts of meat and meat alternatives
(Massachusetts Institute of Technology, 2020)
Awareness of the personal impacts individuals have on the environment is increasing in the United States. There are many different trends in the perception of how individuals can reduce their environmental impact. Examples ...
A model for the dig-in instability in serial sectioning and iterative orthogonal cutting
(Massachusetts Institute of Technology, 2021)
Microtome serial sectioning is a key part of building brain maps of neurological tissue, which are made by serially cutting resin-embedded brain tissue into thin sections, followed by imaging on an electron microscope; ...
Data driven manufacturing risk assessment for turbine engine programs
(Massachusetts Institute of Technology, 2020)
Waste and uncertainty can be managed at all levels of a production process from a program level down to a single step in a manufacturing cell, and is done by assessing risk. Risk is defined as uncertainty in the ability ...
