Ultrafast carotenoid-mediated dynamics in the light-harvesting complex of green plants
(Massachusetts Institute of Technology, 2020)
Photosynthetic organisms, including green plants, have mastered the ability to efficiently capture sunlight and rapidly transport the absorbed energy to drive life-sustaining chemical reactions. At the same time, they have ...
The control of complex double emulsions through reactive interfaces
(Massachusetts Institute of Technology, 2020)
This thesis summarizes the use of interfacial reactions, responsive surfactants, and specific tuning of interfacial tensions to discover novel ways to manufacture and manipulate dynamic double emulsion systems. In Chapter ...
Carbohydrate and bacterial binding specificity of human intelectin-1
(Massachusetts Institute of Technology, 2021)
The mucosal surfaces of the human body exist in close contact with complex communities of resident microorganisms termed the microbiome. The microbiome is crucial for host health, and therefore the host must discern between ...
Metal-triazolate frameworks for the capture of water vapor and ammonia
(Massachusetts Institute of Technology, 2019)
Metal-organic frameworks (MOFs) are emerging materials for applications in gas sorption and separations, however, they are widely believed to be unstable towards coordinating vapors such as water and ammonia due to often-rapid ...
Carbon nanotube-based chemical sensing
(Massachusetts Institute of Technology, 2019)
In this thesis, we introduce approaches to carbon nanotube-based sensing for applications in environmental monitoring, disease diagnostics, and food analysis: In Chapter 1, we introduce carbon nanotube-based sensing. We ...
Enantioselective synthesis of pretomanid & investigations of Raman spectroscopy for through-tube monitoring of reactions
(Massachusetts Institute of Technology, 2019)
Chapter 1: Enantioselective Synthesis of Pretomanid [color illustrations] Pretomanid is a potential cornerstone active pharmaceutical ingredient for the treatment of tuberculosis (TB). It is found in several advanced ...
Stochastic regulation of signaling in lymphocytes
(Massachusetts Institute of Technology, 2016)
Humans are exposed to a variety of infectious pathogens, such as virus, bacteria, etc. But we survive thanks to our immune systems. One of the important immune systems is the adaptive immune system, which mounts pathogen ...
New methods for synthesis and modification of peptides and proteins
(Massachusetts Institute of Technology, 2017)
Chemical modification of peptides and proteins is an enabling suite of tools for tailoring the properties of these biomolecules to specific applications. A number of bio-conjugation reactions allows fine-tuning of the ...
Spectroscopy and dynamics of high orbital angular momentum Rydberg states
(Massachusetts Institute of Technology, 2020)
Rydberg states of molecules with high orbital angular momentum (l >/~ 3) are a unique class of electronic states. These high-l Rydberg states escape the rapid non-radiative decay by predissociation, which is typical of the ...
Large scale analysis of electronic effects in protein structure
(Massachusetts Institute of Technology, 2019)
Protein crystal structures provide a valuable source of information on the internal interactions of a protein and provide a starting point for simulations. In this thesis, we examine how large-scale analysis of protein ...
