Scientists have made a "vitamin mimic" - a molecule that looks and acts just like a natural vitamin to bacteria - that offers a new window into the inner workings of living microbes.
PNNL will manage the newly formed Lightweight Materials National Lab Consortium or LightMAT – a network of nine national labs with technical capabilities that are highly relevant to lightweight materials development and use.
Scientists have shown that a process known as oxidative stress is at work during the rendezvous between certain nanoparticles and immune cells known as macrophages.
Calcium carbonate found in chalk, shells and rocks is one of the most important materials on earth. New insights on how it turns into hard, strong materials will help scientists design materials needed for a low-carbon future.
Nuisance alarm rates in radiation detectors at seaports and ports of entry are down significantly due to PNNL data analysis efforts that are saving time and money at the ports.
Enjoying the beauty of science year-round is easy with a new digital calendar and computer wallpaper containing captivating images that illustrate research at PNNL.
Dr. Morris Bullock and Dr. Monte Helm reviewed the catalysis research at the Center for Molecular Electrocatalysis, where Bullock is the director, in a recent article in Accounts of Chemical Research.
Generating power without gasoline, diesel, or coal could change our nation's energy and security landscape. However, replacing technologies that use fossil fuel with ones that require rare metals is unsustainable.
Making hydrogen economically demands a quick, efficient reaction. Creating that reaction demands a catalyst. CME scientists found that a proton and water-packed environment lets the catalyst work 50 times faster—without added energy.
Quickly, reliably turning wind energy into fuel means looking beyond the catalyst to its foundation, according to a recent study from the Center for Molecular Electrocatalysis.
PNNL researchers have demonstrated a process for the expanded use of lightweight aluminum in cars and trucks at the speed, scale, quality and consistency required by the auto industry.
At PNNL, scientists have elaborated on a strategy to map the catalytic route. Scientists can now explore design decisions with molecular catalysts that store or release energy from the chemical bond in dihydrogen (H2).
Where protons, or positive charges, decide to rest makes the difference between proceeding towards ammonia (NH3) production or not, according to scientists at PNNL and Villanova University.
In an invited ACS Catalysis Viewpoint paper, scientists at PNNL proposed a way to measure and report the energy efficiency of molecular electrocatalysts.
Taking a cue from enzymes, researchers at PNNL placed the amino acid arginine at the periphery of a hydrogen-splitting catalyst that cleaves hydrogen into protons and electrons.
Scientists at the Center for Molecular Electrocatalysis (CME) devised a new computation-based method to predict the catalytic intermediates that could represent a thermodynamic sink.
Like ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast.
