Probing Dynamics of Photosystem | Oligomerization Using SANS and Cryo-EM

On earth, the process of photosynthesis has had to evolve highly adaptive processes to deal with light levels that regularly fluctuate. These organisms are able to respond to changing environmental stimuli to optimize growth in highly variable conditions. Bruce’s project aims to develop an imaging platform for investigating the multiscale phenomena associated with the photoconversion process.

Development of Capacitive Dimensional Change Sensors for Nuclear Materials Measurement

There is a critical need for sensors that provide real-time data regarding material evolution under high accelerated irradiation. One such sensor is currently under development at ORNL.  Coble’s project proposes to create a complementary sensor to provide an alternate measurement modality for in-pile measurement of dimensional change.

Next-generation Neuromorphic Coprocessor Power Consumption in the Beyond Exascale Era

The von Neumann computer architecture has been the basis for computer design for more than half a century, but in recent years neuromorphic computing has emerged as a compliment to that architecture. The primary drawback of these systems currently is the communication between elements and processing units. Dean proposes to develop a new configuration of these elements and processors to address this issue.

Seddik Djouadi

Seddik Djouadi – Min H. Kao Department of Electrical Engineering and Computer Science

Robust Control Design for Power Electronics-Enabled Grid Architectures

Modern power networks are made up of classical electromechanical machines and renewable energy resources interconnected through electronic devices, resulting in characteristics that inhibit performance. Djouadi proposes the creation of a framework to maximize controllability and ensure safe system operations.

Claudia Rawn

Claudia Rawn – Department of Materials Science and Engineering

Complementary X-ray Diffraction Studies for the Characterization of Chromium Dissolution into Molten Chloride Salts

Rawn’s project seeks to leverage the Diffraction Facility at the Joint Institute of Advanced Materials to study the effects of high heat on chromium and molten salts under high heat conditions. The data uncovered may help advance the understanding of the fundamental science behind the depletion of chromium in alloys.

Mining GWAVA for Key Factors Shaping Microbiome Structure

Recent studies have demonstrated a clear overlap in the internal microbial communities among plants, the interactions of which contribute to root microbiome composition. Werner’s project aims to identify and test predictions to define a new role for the bacteria Streptomycetacea in the root microbiome.

 

Steven Wilhelm – Department of Microbiology

Microeukaryotes and Their Viruses : Uncovering Their Hidden Role in One of the Largest Terrestrial Carbon Sinks

In the last two decades, it has become clear that microbes drive nearly all of the major biogeochemical processes on the planet, including activities within microbiomes that range from individual multicellular organisms to entire ecosystems. Wilhelm aims to statistically determine which viruses infect which cells in a microbiome, outside of lab culture efforts, and extend that information to functional processes.
