Improving selectivity in electrochemical CO₂-to-fuels catalysis : the role of catalyst mesostructure, surface structure, and electrolyte
(Massachusetts Institute of Technology, 2018)
Mitigating atmospheric CO₂ levels is an important challenge in curbing anthropogenic climate change. To this end, the storage of intermittently generated renewable energy in the chemical bonds of electro-reduced CO₂ is ...
Steric and kinetic measurements at well-defined surface sites
(Massachusetts Institute of Technology, 2018)
Extended sp² carbon materials display a wide variety of oxidic moieties on edge sites that can be selectively targeted for functionalization. Monarch 1300 (Cabot Corporation) is a carbon black consisting of 10 nm graphitic ...
Reactions of S-nitrosothiols with biomimetic iron complexes and other transition metals
(Massachusetts Institute of Technology, 2014)
Chapter 1. Bioinorganic Chemistry of Nitric Oxide and S-Nitrosothiols The interplay of nitric oxide (NO), biological thiols, and metals has been a topic of intense study since the discovery of NO as the endothelium-derived ...
The selective oligomerization of ethylene with metal-organic frameworks
(Massachusetts Institute of Technology, 2018)
The benefits of heterogeneous catalysis for industry and the society at large cannot be overstated, with approximately 90% of all industrial catalysis being performed with heterogeneous catalysts. Despite the undeniable ...
CO oxidation catalysis with substituted ceria nanoparticles
(Massachusetts Institute of Technology, 2016)
The low-temperature and cost-effective oxidation of carbon monoxide to carbon dioxide remains a fundamental challenge in heterogeneous catalysis that would enable a diverse range of technologies for electrochemical storage ...
Structures of oxalate oxidoreductase : C₂ activation by a microbial TPP-dependent ferredoxin oxidoreductase
(Massachusetts Institute of Technology, 2015)
Oxalic acid is a two-carbon diprotic acid that is toxic to humans. In large doses, it can cause death by poisoning, and in smaller doses over time it can lead to chronic renal disease, such as the formation of kidney stones, ...
Development of N-heterocyclic carbene ligands for nanomaterials in aqueous media and expanding the interface of metal-organic framework (MOF) and polymer chemistry via polyMOFs
(Massachusetts Institute of Technology, 2018)
In the field of coordination chemistry, there are many standard organic ligand designs that are optimized for their ease of synthesis as well as established and favorable properties. Nevertheless, there is still room to ...
Probing the two-dimensional assembly of inorganic complexes and heterocycles for sensing applications
(Massachusetts Institute of Technology, 2017)
Chemiresistive sensing is a facile, affordable, efficient, and translatable way to detect compounds at concentrations as low as parts per billion; however, the key mechanism of molecular sensing is still unknown. In this ...
Biomimetic carboxylate-bridged diiron complexes : from solution behavior to modeling the secondary coordination sphere
(Massachusetts Institute of Technology, 2015)
Chapter 1: Understanding the Utility of Hydrogen Bonding Donors in the Secondary Coordination Sphere of Non-heme Metal Complexes Chapter 1 is a mini-review that covers systematic studies on the effect of hydrogen bonding ...
The reactivity and cation exchange of MOF-5
(Massachusetts Institute of Technology, 2015)
The aim of this thesis is to demonstrate that the inorganic clusters within MOF-5 can be derivatized with redox-active cations for subsequent use in coordination chemistry and small-molecule activation. Rather than reproduce ...
