The Science Polyolefin materials are challenging to recycle, leading to environmental and resource concerns. One strategy for managing this waste is plastic upcycling, where discarded or used plastics are converted into other carbon products. Researchers …
Evangelina Galvan Shreeve, chief diversity officer and director of Science, Technology, Engineering, and Math (STEM) education at Pacific Northwest National Laboratory (PNNL), was recently honored with the Tri-Cities Champion of Diversity Award. Galvan …
Pacific Northwest National Laboratory (PNNL) hosted the inaugural Global Wildlife Data Sharing Conference on May 20–21, 2024. The conference brought together international experts and stakeholders in wildlife health, One Health security, and data science …
Kriston Brooks, a Project Management Office director (PMOD) at Pacific Northwest National Laboratory (PNNL), was recently recognized for his performance as a derivative classifier (DC) at the Annual Classification Officers’ Technical Program Review. Brooks …
The Science Effectively and safely processing nuclear waste involves understanding how ionizing radiation interacts with materials, especially in extreme environments. This study investigated how gamma radiation affects the thermodynamic stability of …
The Science Particles in wildfire smoke can lower air quality and harm human health. Smoke aerosols can also influence weather and climate by modifying cloud formation and changing how much of the sun’s energy is reflected or absorbed by the atmosphere. …
Buoys are critical for various types of marine observations and research. To help inform and support offshore wind energy development, for example, Pacific Northwest National Laboratory (PNNL) deploys lidar buoys that carry scientific instruments to …
The Science An extreme heat event occurred near the North Pole in late December 2015. The near-surface air temperature was above 0 °C, exceeding the melting point for pure water ice. Although this event has been extensively studied, knowledge about similar …
Jordan Corbey is a staff scientist at Pacific Northwest National Laboratory (PNNL), supporting the National Security Directorate. Corbey joined PNNL in 2015 and applies her knowledge to nuclear material processing research. Recently, she was selected as a …
A research paper from a collaborative team including Pacific Northwest National Laboratory (PNNL) researchers received a best scientific paper award from the Mineralized Tissue Group (MTG) of the International Association for Dental Research (IADR). The …
The Science Earth system models (ESMs) are essential tools to understand climate change impacts on wetlands. However, current ESMs usually represent wetland hydrology in oversimplified ways, resulting in low confidence of their projection of wetland …
The Science Aerosols, often emitted alongside greenhouse gases, can brighten clouds and cause significant cooling. However, the uncertainty associated with aerosol–cloud interactions (ACIs) is large and potentially significant enough to mask a sizable …
The Science Earth system models (ESMs) help us understand climate and environmental changes. With advances in computing power, ESMs can now be run at kilometer-scale (k-scale) resolutions, capturing very fine details to better predict extreme weather and …
Today’s manufacturing industry faces several challenges. Companies are looking for ways to increase efficiency, reduce costs, lower carbon emissions and improve their products—all while remaining competitive. At the Department of Energy’s Pacific Northwest …
The Science Two-dimensional (2D) materials have unique physical and chemical properties and potential for a wide variety of applications. Peptoids, a type of molecule, compose a class of sequence-defined polymers that mimic biological compounds and can …
With the advent of exascale computing, scientists can perform complex calculations to address difficult challenges in research for energy and national security. However, some problems are still inaccessible for even these powerful computers. For certain …
The Science Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a specialized mass spectrometry technique. It can be used to identify the composition of solid surfaces, providing elemental, isotopic, and molecular information with part per …
The Science Arctic Amplification (AA)—the amplified surface warming in the Arctic relative to the global mean—is a robust feature of climate change. However, there is a considerable spread in the reported magnitude of AA. While earlier observations and …
The Science The impact of aerosol–cloud interactions (ACIs) on the Earth’s radiative budget is among the most uncertain aspects of climate prediction. Earth system models estimate the contribution of ACIs to Earth’s energy budget in different climate …
RICHLAND, Wash.—Just how much heat does city sprawl add to large-scale warming? That’s one longstanding question researchers sought to answer in a new study recently published in the journal One Earth. Once thought to cover too little of the Earth’s …
