Continuous ion-selective separation by shock electrodialysis
(Massachusetts Institute of Technology, 2019)
Cleaning water remains a challenge across sectors and across the globe. Many go without access to clean drinking water simply because the technologies that exist are too expensive in capital or energy. Areas thought to ...
Pathway and protein engineering for improved glucaric acid production in Escherichia coli
(Massachusetts Institute of Technology, 2019)
Microbial fermentation is an attractive method for the renewable production of chemicals. Glucaric acid was identified as a "top value added chemical from biomass" by the Department of Energy in 2004, and a biological route ...
Physics-based models of hysteresis in multiphase flow in porous media
(Massachusetts Institute of Technology, 2019)
We propose a novel probabilistic framework based on pore-scale probabilistic events to derive a theory of hysteresis in multiphase flow in porous media. In particular, we define the pore-space accessivity to contrast the ...
Theoretical and experimental study of electrochemically mediated adsorption processes
(Massachusetts Institute of Technology, 2019)
Water treatment by electrosorption is a topic of increasing interest in recent years due to the high efficiency, low cost, small footprint and no secondary treatment required. Electrochemically mediated adsorption, is one ...
Ideal reversible polymer networks : theory and applications
(Massachusetts Institute of Technology, 2019)
Hydrogels are crosslinked polymer networks with high water contents that can be designed to have similar properties as native tissue. Due to the tunability and unique properties of this class of materials, they are considered ...
Ion-exchanged metal-organic frameworks for industrially relevant catalysis applications
(Massachusetts Institute of Technology, 2019)
The inorganic clusters of metal-organic frameworks (MOFs) offer a unique combination of synthetic tunability, structural uniformity, and site accessibility uncommon in conventional heterogeneous catalysts. As such, the ...
Engineering nanolayers for localized delivery of siRNA
(Massachusetts Institute of Technology, 2020)
RNA interference (RNAi) is a promising technology for therapeutic application. The RNAi pathway involves sequence-specific gene silencing directed by RNA fragments of 21-23 nucleotides long known as short interfering RNA ...
Tuning geometric and electronic structure of noble metal with core-shell platform as enhanced catalysts
(Massachusetts Institute of Technology, 2020)
The noble metals (NMs) are special materials satisfying the Sabatier principle which bind adsorbates neither too strongly nor too weakly. Along with the resistance to corrosion and bulk oxidation, this makes noble metals ...
Novel applications of ionic Liquids in molecular crystallization
(Massachusetts Institute of Technology, 2019)
In recent years, pharmaceutical companies have made efforts to study the properties of other potential solvents in active pharmaceutical ingredient (API) synthesis and manufacturing, in order to seek substitutes for toxic ...
Sequence design principles for 3D wireframe DNA origami
(Massachusetts Institute of Technology, 2018)
DNA is a highly programmable molecule that can be designed to self-assemble into nearly arbitrary 2D and 3D nanoscale structures. DNA origami is a particularly versatile method to achieve complex molecular architectures. ...
