To better understand the effects of solution chemistry on particle aggregation in the complex legacy tank wastes at the Hanford (WA) and Savannah River (SC) sites, we have performed a series of tumbler small- and ultra-small-angle neutron scattering experiments on 20 wt % solid slurries of...

Understanding molecular-scale factors governing the precipitation of aluminum hydroxides, such as gibbsite, under alkaline conditions is important for the formation of laterite deposits, as well as aluminum processing. However, mechanisms enabling tetrahedral aluminate ions to assemble into...

Nonadiabatic dynamical processes such as proton-coupled electron transfer and excited state intramolecular proton transfer have been the subject of much research. One of the promising theoretical methods to describe these processes is the nuclear–electronic orbital (NEO) approach. This approach...

Over the last several decades, there have been several studies examining the radiation stability of boehmite and other aluminum oxyhydroxides, yet less is known about the impact of radiation on boehmite dissolution. Here, we investigate radiation effects on the dissolution behavior of boehmite by...

ABSTRACT Tissue- and cell-specific expression patterns are highly variable within and across individuals, leading to altered host responses after acute virus infection. Unraveling key tissue-specific response patterns provides novel opportunities for defining fundamental mechanisms of virus-host...

Our understanding of the process of mineral nucleation is starting to evolve from the solely thermodynamical aspects in classical nucleation theory toward a mechanistic study of reactions influenced by solvation structures of ions and their dynamics. A knowledge of how these atomic and molecular...

Andrea is a Post Masters Research Associate at PNNL. She is recently working on the CEDS project, tracking and analyzing historical anthropogenic emissions. Before joining JGCRI, she received her master's in Renewable and Clean Energy and bachelor's in Mechanical Engineering from the University of...

Smith is an Earth Scientist at PNNL whose recent research has focused on the interactions between air pollution and climate, the potential near-term role of short-lived climate forcers, and the development of comprehensive estimates of historical air pollutant emissions over the industrial era...

Hamza is a Post Masters Research Associate at JGCRI within the Earth and Biological Sciences Directorate of PNNL. He has recently been working on the CEDS project to help develop a database of historical pollutant emissions for research and analysis. Prior to joining PNNL, Hamza completed graduate...

"DNA Viral Diversity, Abundance, and Functional Potential Vary across Grassland Soils with a Range of Historical Moisture Regimes" Soil viruses are abundant, but the influence of the environment and climate on soil viruses remains poorly understood. Here, we addressed this gap by comparing the...

"Deconstructing the Soil Microbiome into Reduced-Complexity Functional Modules" The soil microbiome represents one of the most complex microbial communities on the planet, encompassing thousands of taxa and metabolic pathways, rendering holistic analyses computationally intensive and difficult. Here...

Representing biological networks as graphs is a powerful approach to reveal underlying patterns, signatures, and critical components from high-throughput biomolecular data. However, graphs do not natively capture the multi-way relationships present among genes and proteins in biological systems...

Soil fungi facilitate the translocation of inorganic nutrients from soil minerals to other microorganisms and plants. This ability is particularly advantageous in impoverished soils, because fungal mycelial networks can bridge otherwise spatially disconnected and inaccessible nutrient hotspots...

Dr. Yinghui Wu is an Assistant Professor in the Department of Computer and Data Sciences, Case School of Engineering at Case Western Reserve University, US, and a joint staff scientist at Pacific Northwest National Lab, US. He received his Ph.D. in Computer Science from the University of Edinburgh...

Sheng Guan is currently pursuing a Ph.D. degree from Case Western Reserve University under the supervision of Dr. Yinghui Wu. Sheng got his master’s and bachelor’s degree from Florida International University (major in computer science, 2017), The Hong Kong University of Science &Technology (major...
