Investigating lipid corona formation onto polystyrene nanoparticles through fluorescence correlation spectroscopy
Get PDFWhen a nanoparticle enters a biological environment, molecules are known to adsorb on the surface forming a corona. Systematically studying the formation of a corona is important to develop knowledge as to how a given nanomaterial will transform once entering a biological environment. A common interface met by a nanomaterial in the human body is the cell membrane, which is composed of phospholipid bilayer. Fluorescence correlation spectroscopy (FCS) is a promising tool that can be used to probe nanoparticle-cell interactions. FCS experiments focusing on exposure of lipid vesicles to different polystyrene nanoparticles indicate possible formation of a lipid corona. Further study varying the nanoparticle charge and lipid vesicle fluidity can help elucidate the mechanism of lipid corona formation. Such work can provide insight into understanding the complex nature of the nano-bio interface.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2017-12-01The student, Lisa Jacob, accepted the attached license on 2015-12-08 at 15:54.The student, Lisa Jacob, submitted this Thesis for approval on 2015-12-08 at 16:14.This Thesis was approved for publication on 2015-12-08 at 16:53.DSpace SAF Submission Ingestion Package generated from Vireo submission #8972 on 2016-03-02 at 14:07:53Made available in DSpace on 2016-03-02T20:24:17Z (GMT).

The 2004 Aceh-Andaman Earthquake: early clay dehydration controls shallow seismic rupture
No full textThe physical state of the shallow plate-boundary fault governs the updip extent of seismic rupture during powerful subduction zone earthquakes and thus on a first order impacts on the tsunamigenic hazard of such events. During the 2004 Mw 9.2 Aceh-Andaman Earthquake seismic rupture extended unusually far seaward below the accretionary prism causing the disastrous Indian Ocean Tsunami. Here we show that the formation of a strong bulk sediment section and a high fluid-pressured predécollement, that likely enabled the 2004 rupture to reach the shallow plate-boundary, result from thermally controlled diagenetic processes in the upper oceanic basement and overlying sediments. Thickening of the sediment section to >2 km ~160 km seaward of the subduction zone increases temperatures at the sediment basement interface and triggers mineral transformation and dehydration (e.g. smectite–illite) prior to subduction. The liberated fluids migrate into a layer that likely host high porosity and permeability and that is unique to the 2004 rupture area where they generate a distinct overpressured predécollement. Clay mineral transformation further supports processes of semi-lithification, induration of sediments, and coupled with compaction dewatering all amplified by the thick sediment section together strengthens the bulk sediments. Farther south, where the 2005 Sumatra Earthquake did not include similar shallow rupture, sediment thickness on the oceanic plate is significantly smaller. Therefore, similar diagenetic processes occur later and deeper in the subduction zone. Hence we propose that shallow seismic rupture during the 2004 earthquake is primarily controlled by the thickness and composition of oceanic plate sediments

Microbial enrichment culture responsible for the complete oxidative biodegradation of 3‑Amino-1,2,4-triazol-5-one (ATO), the reduced daughter product of the insensitive munitions compound 3‑Nitro-1,2,4-triazol-5-one (NTO)
No full text3-Nitro-1,2,4-triazol-5-one (NTO) is one of the main ingredients of many insensitive munitions, which are being used as replacements for conventional explosives. As its use becomes widespread, more research is needed to assess its environmental fate. Previous studies have shown that NTO is biologically reduced to 3-amino-1,2,4-triazol-5-one (ATO). However, the final degradation products of ATO are still unknown. We have studied the aerobic degradation of ATO by enrichment cultures derived from the soil. After multiple transfers, ATO degradation was monitored in closed bottles through measurements of inorganic carbon and nitrogen species. The results indicate that the members of the enrichment culture utilize ATO as the sole source of carbon and nitrogen. As ATO was mineralized to CO₂, N₂, and NH₄⁺, microbial growth was observed in the culture. Co-substrates addition did not increase the ATO degradation rate. Quantitative polymerase chain reaction analysis revealed that the organisms that enriched using ATO as carbon and nitrogen source were Terrimonas spp., Ramlibacter-related spp., Mesorhizobium spp., Hydrogenophaga spp., Ralstonia spp., Pseudomonas spp., Ectothiorhodospiraceae, and Sphingopyxis. This is the first study to report the complete mineralization of ATO by soil microorganisms, expanding our understanding of natural attenuation and bioremediation of the explosive NTO.Journal ArticleFinal article publishe
Dark Matter and the Dinosaurs: An Evening with Dr. Lisa Randall [Video]
No full textDr. Lisa Randall is a world-renowned theoretical physicist, best-selling author, and the Frank J. Baird, Jr. Professor of Science at Harvard University, where she researches and teaches theoretical particle physics and cosmology. Her most recent book, Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe (2015) received critical praise from far and wide, continuing a string of bestselling science books of the highest caliber. One esteemed fellow physicist hailed the book as “a masterpiece of science writing: a detective story that illuminates the nature of scientific research while explaining how our very existence may be connected to unexpected properties of the dark matter that fills the universe.”
Dr. Randall’s research connects theoretical insights to puzzles in our current understanding of the properties and interactions of matter. She has developed and studied a wide variety of models to address these questions, the most prominent involving extra dimensions of space. Her work has involved improving our under-standing of the Standard Model of particle physics, supersymmetry, baryogenesis, cosmological inflation, and dark matter. Randall’s research also explores ways to experimentally test and verify ideas and her current research focuses in large part on the Large Hadron Collider and dark matter searches and models.
