A multi-institution research team found how the protein environment surrounding some enzymes can alter the direction of a cellular reaction, as well as its rate—up to six orders of magnitude—in a phenomenon referred to as catalytic bias.
Their consistency and predictability makes tidal energy attractive, not only as a source of electricity but, potentially, as a mechanism to provide reliability and resilience to regional or local power grids.
New technique galvanizes iron-based nanoparticles to create an exceptional catalyst. PNNL researchers describe a new technique that produces metal nanoparticles supported on solid iron oxide, in one step, at near room temperature.
On World Oceans Day, an international team of marine scientists reports that the potential impact of marine renewable energy to marine life is likely small or undetectable, though some uncertainty remains.
In a recent review article, an interdisciplinary team of researchers led by PNNL biogeochemist Nick Ward proposed a path to refining the representation of coastal interfaces in Earth systems models used to predict climate.
With the help of a diagnostic tool called the Salish Sea Model, researchers found that toxic contaminant hotspots in the Puget Sound are tied to localized lack of water circulation and cumulative effects from multiple sources.
PNNL researchers and professional staff led discussions ranging from biothreats and climate change to science careers at the 2020 annual meeting of the American Association for the Advancement of Science, held this year in Seattle.
A new Co-Optima report describes an assessment of 400 biofuel-derived samples and identifies the top ten candidates for blending with petroleum fuel to improve boosted spark ignition engine efficiency.
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.
