Zhe is a scientist at PNNL. His recent efforts involve understanding the impact of climate change to mesoscale convective systems and extreme precipitation and using innovative methods and advanced observations to evaluate and improve the representations of convective clouds, mesoscale convective...
Jianfeng is a Post Doctorate Associate at PNNL. He is interested in combining atmospheric chemistry and physics to explore the comprehensive impacts of atmospheric processes on air quality and climate change. His recent research is to investigate the relationship between convection and extreme...
As part of the Pacific Northwest National Laboratory’s (PNNL) Science Focus Area program, we are investigating the impact of environmental change on microbial community function in grassland soils. Three grassland soils, representing different moisture regimes, were selected for ultra-deep...
Increasing levels of nutrients, persistent hypoxia, harmful algal blooms, and increased frequency of fish kills are degrading the ecological health of the Salish Sea. An improved version of a diagnostic hydrodynamic and biogeochemical model (nutrients, phytoplankton, carbon, dissolved oxygen, and pH...
Professor Suresh D. Pillai is the Director of the National Center for Electron Beam Research (NCEBR). He brings together researchers from across the Texas A&M University System and around the world to harness their skills to make paradigm-shifting changes in how we address contemporary food, public...

Emily Craven has spent the last 20 years finding better ways to use radiation for industrial applications. An engineering physicist and licensed Professional Engineer by training, Emily is a recognized expert in gamma, electron beam and x-ray sterilization. She has been a radiation physicist and a...

The literature on the effects of radiation on the properties of various polymers and composites has been briefly reviewed for the purpose of identifying polymeric materials that could be irradiated to improve their performance. Radiation treatment of polymers may lead to cross-linking or chain...

Scientific advancements in healthcare driven both by technological breakthroughs and an aging and increasingly obese population have lead to a changing medical device market. Complex products and devices are being developed to meet the demands of leading edge medical procedures.Specialized materials...

An alternative method is presented for determining the maximum acceptable dose in products irradiated in electron beam processes. When the presentation of an individual product to the radiation field results in a high dose uniformity ratio, this can present a challenge for accurate testing of a...

Ionizing radiation has been found to be widely applicable in modifying the structure and properties of polymers, and can be used to tailor the performance of either bulk materials or surfaces. Fifty years of research in polymer radiation chemistry has led to numerous applications of commercial and...

Today, the most common methods used for medical device sterilisation are by gaseous ethylene oxide and by electron beam or gamma irradiation. With X-ray sterilisation about to enter the market, its material compatibility needs to be assessed at doses typically encountered during a sterilisation...

Predicting phenotypic expression from genomic and environmental information is arguably the greatest challenge in today’s biology. Being able to survey genomic content, e.g., as single-nucleotide polymorphism data, within a diverse population and predict the phenotypes of external traits, represents...
Buildings consume over 30% of the total primary energy consumed worldwide and contribute to a third of the world greenhouse gas (GHG) emissions. In the US, buildings consume over 40% of total energy and contribute to almost 38% in GHG emissions. In addition, buildings in the US consume over 75% of...
