Double Photoionization to Probe Electron Correlation in Atomic and Molecular Systems with More than Two Electrons - National Science Foundation- $75,000

Principal Investigator: Dr. Frank Yip, Associate Professor

This project will examine the consequences of correlated electron dynamics of small atoms and molecules with more than two electrons in order to better understand the similarities and differences in different target atoms and molecules that result from having many electrons. Electron correlation is a fundamental phenomena with great impacts on the behavior and structure of all matter. Many decades of research towards developing more accurate ways of accounting for the non-approximated dynamics of electronic motion in even the simplest atoms and molecules have been focused on bound states (energy levels of atoms, potential curves of molecules, etc.) but the consequences of this correlation also greatly impact the resulting double continua when two electrons are ejected from a target by photons. These correlated electron interactions are fundamental to the organization and structure of matter at the atomic level and continue to be of vital importance to study and better understand. Broader consequences of pursuing more a complete understanding of electron correlation in simple atoms and molecules with more than two electrons would impact many other fields of study, including chemistry, atomic and molecular physics, molecular biology, and material science, to name a few.

This project will investigate the impacts of these fundamental electronic correlations for non-trivial atoms and molecules with more than two electrons in order to better understand the ways that the initial and final states of the electrons that remain bound to the atom or diatomic molecule can affect the two photoejected electrons leaving the others behind. Theoretical calculations describing these events from first principles will be applied to targets with many electrons that continue to interact with the fully correlated electrons before, during and after the photoionization event. It is hoped that this project can further elucidate the broader consequences of how all of the electrons bound to an atom or molecule can affect those that will be moved into the continuum and how consequences of symmetry and electronic structure impacts outgoing electrons. Both time-dependent and time-independent approaches will be explored. The work is closely coupled to kinematically complete experimental investigations of these systems.


Development of a Neurosleeve System for Stroke Rehabilitation - California State University Chancellor's Office - $5,421

Principal Investigator: Dr. Tomas Oppenheim, Assistant Professor 

The aim of this project is to develop a low cost and highly sensitive Neurosleeve for tracking arm and hand joint angles of stroke patients for rehabilitation purposes.  A low-cost (<$500) and highly accurate joint-angle tracker will prove extremely beneficial for (1) better understanding of how much motor skill is lost after a stroke; (2) development of novel rehabilitation methods to improve stroke patient recovery; (3) allowing the patients to take these devices home and perform these tests.  Once a reliable, accurate, and low cost method of tracking arm joint-angles is established, stroke patients will be recruited to monitor their motor skill.  The high accuracy of this numerical data allows for statistical analysis that will elucidate the details of motor skill loss.  Based on these results, novel rehabilitation methods can be designed. 


Collegiate Wind Competition 2018 – National Renewable Energy Laboratory (U.S. Department of Energy) - $18,308

Principal Investigator: Dr. Thomas Nordenholz, Professor 

The Collegiate Wind Competition challenges undergraduate students from a variety of programs to offer a unique solution to a complex wind energy project; providing each student with real-world experience as they prepare to enter the wind industry workforce.


Nutrient Processing and Links to Foodweb – Delta Stewardship Council - $71,615

Principal Investigator: Dr. Alex Parker, Associate Professor 

The focus of this project is to quantify the links between wastewater nitrogen and phytoplankton standing stock, community composition and carbon and nitrogen production.  We will: 1. Validate in situ monitoring approaches for phytoplankton standing stock and community composition (i.e. using size-fractionated chlorophyll-a and diagnostic phytopigments via HPLC) and 2. Provide estimates of ambient and nitrogen-saturated phytoplankton NH4 and NO3 uptake rates as well as C uptake.  This project will provide much needed baseline characterization of nutrient processes in the Delta prior to Regional Sanitation upgrades.


Ballast Water Treatment - US Maritime Administration (MARAD) - Current Funding $300,000

Principal Investigator: Bill Davidson, Director Golden Bear Facility

Ships traveling the oceans will soon be required by the International Maritime Organization to have certified ballast water treatment systems in place to identify and combat the marine organisms that can live in water taken onboard a ship in one port, and later discharged in a new marine environment.  These organisms can multiply rapidly, outpacing the growth of native species and causing havoc for fisheries, seabeds, and friendly organisms that routinely absorb other contaminates.  Additionally international requirements specify that a third party analyze test data and certify that systems meet the latest standards.

Cal Maritime has partnered with industry, government and research teams to create the first of its kind testing facilities, the Shipboard Ballast Water Treatment test facility aboard Cal Maritime's 500-foot Training Ship Golden Bear.  Available year round for testing, the Golden Bear is truly a unique environment for testing ballast water systems.

The project allows the Golden Bear to function as a "plug-and-test" platform for research teams.  Organizations can install their system in a standard 20-foot shipping container, using connection specifications provided by Cal Maritime to access ballast water tanks, electricity, and ancillaries.
