Earth's Toxic Nano-compartments : Metal Behavior During Natural Nano-particle Maturation
(2015-04)The purpose of this study was to answer this question: how do nanoparticles in natural, metal rich environments behave in terms of metal content with growth into a more "crystalline" phase? -
Evaluation of Microfiber Cloths in the Removal of Microorganisms
(2021-04)Staphylococcus aureus is a species of bacteria that can cause a variety of different illnesses in humans, from mild skin infections to life-threatening diseases such as meningitis. Bacillus subtilis and Escherichia coliare ... -
Evaluation of Nanoparticles and Colloids in a Public Water Supply from Well-Head to the Consumer Tap
(2017-03-27)Nanoparticles (NP) (<100nm in one dimension) are ubiquitous in low temperature environments including surface and groundwater. NP are extremely reactive due to large ratio of surface area to volume. Synthetic NP used in ... -
Mechanical Properties of Organic-Inorganic Composite Films : Comparing the Impacts of Flexible vs. Rigid Organic Components
(2025-04)A series of organic-inorganic composite films composed of close-packed, alkanethiol-capped gold nanoparticles and rigid, aromatic dithiol crosslinking molecules were assembled upon the air-water interface within a Langmuir ... -
Mechanical Properties of Organic-Inorganic Composite Films: Comparing the Impacts of Flexible vs. Rigid Organic Components
(2024-04)A series of organic-inorganic composite films composed of alkanethiol-capped gold nanoparticles and dithiol crosslinking molecules were assembled upon the air-water interface within a Langmuir trough. The mechanical ... -
Metal Sequestration During Aggregation Based Crystal Growth
(2018-01-09)This project is focused on determining how associated metals of environmental concern (especially Pb) behave during aggregationbased crystal growth as a function of increasing Crystallinity Index (CI). -
Morphological and Trace Element Analysis of Nano Spherical Soot from the Central Valley of California
(2018-04-13)Cancer clusters in the Central Valley of California have been linked to metal exposure. One suspected pathway for metal exposure is through air particulates and soot makes up a large portion of air particulates in many ... -
Native Ligand Shell Rigidity and Crosslinking Ligand Dimensions Determine Interparticle Spacing In 2-D Arrays of Covalently-Crosslinked Gold Nanoparticle Films
(2019-05)Alkane thiol-capped gold nanoparticles were compressed into 2-d arrays using a Langmuir trough, and covalently crosslinked using a solution of alkanethiols to yield a flexible film of nanoparticles. These nanoparticles ... -
Prospecting Through TEM Analyis of Metallic Nanoparticles in Groundwater
(2018-03-07)With the search for new deposits of metallic resources pushing prospecting into increasingly poorly exposed areas, this project aims to test an experimental prospecting technique developed in China to discover potential ... -
Structural Characteristics of Crosslinked Gold Nanoparticle Networks Formed at an Air-water Interface
(2013-05)The structural dynamics of thin films of surfactant molecules can be characterized by their behavior in a Langmuir trough, where the molecules reside at the air-water interface. Parameters such as molecular order, film ... -
