Nitrogen oxides, also known as NOx, form when fossil fuels burn at high temperatures. When emitted from industrial sources such as coal power plants, these pollutants react with other compounds to produce harmful smog.

A multi-institute team develops an imaging method that reveals how uranium dioxide (UO2) reacts with air. This could improve nuclear fuel development and opens a new domain for imaging the group of radioactive elements known as actinides.

Researchers are seeking to better understand how nitrogenase acts as a catalyst to break down nitrogen.

Researchers at PNNL have developed a model that predicts outcomes from the algae hydrothermal liquefaction process in a way that mirrors commercial reality much more closely than previous analyses.

PNNL’s Tim Johnson and lead researcher Tanya Myers were recently selected for the Applied Spectroscopy William F. Meggers Award.

Researchers at PNNL have introduced an alternative method using a molecular-based pump that could potentially use a quarter less energy than the age-old mechanical pump.

Researchers apply numerical simulations to understand more about a sturdy material and how its basic structure responds to and resists radiation. The outcomes could help guide development of the resilient materials of the future.

PNNL and National Renewable Energy Laboratory have partnered on a first-of-its-kind tool that estimates costs of catalysts.

The U.S. Nuclear Regulatory Commission, U.S. Army Corps of Engineers, and PNNL partnered to complete—in record time—an environmental impact statement for the nation’s first small modular nuclear reactor, to be sited at Clinch River, Tenn.

It’s hot in there! PNNL researchers take a close, but nonradioactive, look at metal particle formation in a nuclear fuel surrogate material. What they found will help fill knowledge gaps and could lead to better nuclear fuel designs.

Researchers at PNNL and their collaborators have made a significant improvement to a catalyst that is more rugged and can reduce tailpipe pollution at lower temperatures than existing methods.

Kelsey Stoerzinger leverages advances in surface chemistry to develop materials for clean energy and water purification.

Several years ago, a relatively new catalyst for vehicle emission control began showing failure. A team at PNNL found that this seemingly suicidal catalyst wasn’t actually self-destructing but was the victim of an external assailant.

The atomically precise insights obtained from our experiments and theoretical calculations helped to develop efficient electrochemical interfaces.

Xenon search successful! A new scanning transmission electron microscope helps PNNL researchers find xenon deep in a section of nuclear fuel cladding.

Researchers used novel methods to safely create and analyze plutonium samples. The approaches could prove influential in future studies of the radioactive material, benefitting research in legacy, national security and nuclear fuels.

Aluminum oxyhydroxide (boehmite) nanoplatelets align and attach to form neatly ordered stacks, a novel findings that involves both experimental and computational research.

Researchers explore why invisible water films adsorbed to mineral surfaces behave differently than bulk liquids.

A team of researchers reveal new insights about how nitrogenase does its job.

Researchers developed a new hybrid catalyst that achieved chemo-selective and site-selective hydrogenation of aromatic molecules under low pressure of dihydrogen and mild temperature.
