Digging into Clouds from the Bottom Up
Researchers created new code commands to compute the cloud droplet number concentration using existing surface measurements
Scientists at PNNL got creative with the data they already have to calculate a cloud property normally acquired by research aircraft flying through it. What is this valuable measurement they seek? The cloud droplet number concentration provides insight into how reflective and long-lasting a cloud is, to understand the amount of sunlight energy that hits Earth's surface.
A New Way to Model the Complex Metabolism of Microbial Communities
Using community-level data to reconstruct elusive multi-species metabolic networks
A new paper in the Journal of Cellular Physiology proposes a novel way to model and predict the metabolic interactions across species in microbial communities. It is authored by five researchers at the PNNL and two colleagues at Argonne National Laboratory.
New Material Has Potential to Cut Costs and Make Nuclear Fuel Recycling Cleaner
Computer modeling helps pinpoint best material out of a hundred thousand options
Researchers are investigating a new material that might help in nuclear fuel recycling and waste reduction by capturing certain gases released during reprocessing. Conventional technologies to remove these radioactive gases operate at extremely low, energy-intensive temperatures. By working at ambient temperature, the new material has the potential to save energy, make reprocessing cleaner and less expensive. The reclaimed materials can also be reused commercially. Appearing in Nature Communications, the work is a collaboration between experimentalists and computer modelers exploring the characteristics of materials known as metal-organic frameworks.
