Investigating an impact origin for Hadean zircons from Western Australia

Hadean zircons, found in the Jack Hills, Western Australia, are the oldest known materials on Earth, dating back to nearly 4.4 Ga or only ~150 Ma after formation. These tiny grains have been essential in transforming our view of the Hadean from a hot, hellish environment to one that appears much more hospitable to life with continental crust, water, and possibly even plate tectonics. Understanding the magmatic environment that leads to the formation of these ancient grains is fundamental to interpreting the geochemical signatures within them. Hypothesis of formation environments have ranged from plate boundary interactions to impact melt sheets. One important characteristic of the Jack Hills zircons is their unique inclusion assemblage,...

Search for Magnetic Monopoles: from the Large Hadron Collider to Space

Student can get involved in the following aspects of the project: 1. Development of novel radiation detectors optimized for the magnetic monopole searches. The detectors are to be deployed at the Large Hadron Collider, CERN, and in the Low Earth Orbit using CubeSat satellites. No prior experience with detector development required. 2. Applying Deep Learning techniques to the data analysis of the MoEDAL experiment at the LHC. The work involves operation of a GPU based computing system, application of convolutional neural networks for event classification. No prior experience with machine learning methods required. Familiarity with programming languages (Python, C) is advantageous. Position is initially unpaid. ...

Synthesis and characterization of shape/size-controlled metal oxides nanopowders

The research objective of this project is to advance the fundamental understanding of structural and chemical features (morphology, size, atomic-level structure, etc) of metal oxide nanomaterials in order to develop stable catalysts with high reducibility at low temperatures for the application in automotive catalytic converter. Using low-temperature hydrothermal method, students will prepare a series of high surface-area metal oxides nanopowders with a focus on controlling particle morphology and size in such a way that highly catalytically active crystal faces are exposed on the particle surfaces. X-ray diffraction (XRD) will be used to establish the overall crystal structures of the nanopowders. The overall reducibility and catalytic act...

Xylochemistry - Chemistry for a Sustainable Future.

Xylochemistry - the use of wood as a source of raw materials for chemical synthesis - provides a climate-neutral alternative to the conventional use of fossil carbon sources such as natural gas or oil. Xylochemistry and specifically the STANCE Consortium (a collaboration between UA, the Johannes Gutenberg University-Mainz, Germany, and the Virginia Commonwealth University) is developing an economically and environmentally sustainable technological path from wood to commodity chemicals, materials, pharmaceuticals, and fuels. In the early days of organic chemistry natural substances such as ethanol or bitter almond oil (benzaldehyde) were the only organic chemical substances available with relative purity. In the 19th century the initiall...

Characterizing the Physical/Chemical Evidence of Volcanic Lightning

Volcanic eruptions and lightning strikes are two of the most impressive and destructive natural phenomena, but much is still unknown about the fundamental processes that allow these events to occur. An emerging new line of research is seeking to determine the complex relationship between explosive volcanism and lightning, specifically: The effect of lightning discharge on the textural and chemical properties of volcanic ash and the resulting signature of volcanic lightning occurrence in the geologic record. Fundamental questions addressed by this project, and the integral educational component that involves learners of all ages, may result in potentially transformative concepts the geosciences, atmospheric sciences, and hazard assessment. ...

Computational peptide chemistry

Advanced computational electronic structure methods will be used to calculate the geometries, vibrational frequencies, energetics, and excited state properties of important compounds of biological interest. Both correlated molecular orbital theory and density functional theory will be used. The focus of the work is on charging of peptides for explaining mass spectrometry results for both cationic and anionic peptides. The cationic work will focus on transition metal ion charging. Both types of studies are relevant to the study of the Human proteome....

computational catalysis

The control of chemical transformation via catalysis is both an exceptional intellectual challenge and critically important to the Nation. Catalysis is central to energy production and utilization, to chemical manufacturing, to the minimization of environmental impact, and it has been arguably the single most important agent for sustainable development in the developing world. The revolutions in nanotechnology and high performance computing provide unprecedented new opportunities to elucidate the fundamental principles governing the control of chemical transformation by catalysts. Indeed, the coupling of theory, modeling and simulation with experiment will provide the most profound insights into catalyst behavior and thus enable the design ...

Reconstructing paleoclimate in the Late Cretaceous

One of my field areas is in the Hell Creek are of central-eastern Montana which contains rocks that preserve the Cretaceous - Paleogene (K-Pg) boundary, which is the interval where dinosaurs (and many other organisms) went extinct. I have two projects related to samples I've collected from the area: 1. I'm trying to reconstruct climatic conditions in the latest Cretaceous using geochemical tests of fossil mussel shells and descriptions of rock types. This work will help us understand what environments fossils are preserved in, and the hydrology of the area during the Cretaceous. 2. I've also collected samples at high resolution across the K-Pg for chemical tests of the sediment. This will help us locate the K-Pg boundary precisely, assess...
