The 2011 accident at the Fukushima-Daiichi plant in Japan inspired extensive research and analysis that elevated nuclear energy into a standard bearer for safety. It also inspired a number of studies at the U.S. Department of Energy's (DOE) Argonne National Laboratory. Scientists want to look more closely at nuclear fuel materials to better understand how they will behave at extremely high temperatures.

In a global first, scientists working in the Clarion-Clipperton Zone in the North Pacific Ocean have found that metallic nodules on the seafloor produce their own oxygen, dubbed "dark oxygen."

The quest for boundless energy takes an electrifying turn with this magic mineral.

By design, synthetic molecules typically have specific jobs to prevent or accelerate reactions between other molecules. To help control more complicated reactions, researchers may harness spare space in one molecule to synthesize another chemical structure. The host-guest assembly can better induce the specific desired reaction than either component individually—if the scientists designing the assembly get it right.

The eutectic structure of metals and ceramics occurs when multiple solid phases solidify from a liquid phase, forming a three-dimensional (3D) pattern through a self-organizing phenomenon. Traditionally, it was believed that eutectic structures could only be obtained through a melt-solidification process.

A U.S.-based rare earth supply chain could boost clean energy and electric vehicles — and military weapons.

The so-called three-way catalytic converter in the exhaust system of a car consists of expensive materials and only works correctly when the exhaust gases have a temperature that is several hundred degrees Celsius.

Scientists from Jilin University, the Center for High Pressure Science and Technology Advanced Research, and Skoltech have synthesized lanthanum-cerium polyhydride, a material that promises to facilitate studies of near-room-temperature superconductivity. It offers a compromise between the polyhydrides of lanthanum and cerium in terms of how much cooling and pressure it requires. This enables easier experiments,…

Visible Light Absorption of Titanium Dioxide Through Cerium Synchronous Doping in Anatase The introduction of rare earth elements into TiO2 can effectively improve the electron-hole separation of TiO2 and prolong the visible light response of TiO2. Cerium (Ce) shows variable valence states Ce3+/

In Germany, wind power turbines, catalytic converters, optical cables and plasma monitors: They all contain Rare Earth metals. Since these 17 metal elements are indispensable to modern technologies, cost and demand are constantly rising. Minable deposits are limited and production is often difficult and harmful to the environment. Recycling these resources as efficiently as possible, […]

A team of researchers led by scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has discovered the mechanisms behind a very effective catalyst for methane dry reforming, a chemical reaction in which two greenhouse gases, methane and carbon dioxide, are simultaneously converted into a mixture of hydrogen molecules and carbon monoxide. This mixture is generally called synthesis gas…

Atomica attracts capital from Cerium Technology Ventures, Novo Tellus Capital Partners, and St. Cloud Capital

Although much of the discourse on reducing vehicle emissions centers on electric vehicles (EV), their sales remain low—with EV vehicles accounting for a mere 1% of car purchases in Japan in 2021. Meanwhile, the European Union is expected to pass stricter emission standards in the near future. This makes improving the performance and functionality of exhaust gas purification catalysts in petrol or diesel-powered…

A new MIT-developed material could be used by Tesla to produce all-electric vehicles with just a few massive, 3D-printed parts.

University of Central Florida material sciences engineers Melanie Coathup and Sudipta Seal have designed a cerium oxide nanoparticle—an artificial enzyme—that protects bones against damage from radiation. The nanoparticle has also shown abilities to improve bone regeneration, reduce loss of blood cells and help kill cancer cells.

Researchers have developed an innovative catalyst for the synthesis of propylene, which has potential benefits for the chemical industry and carbon recycling. Their findings were reported in the journal Nature Catalysis.

President Donald Trump says the United States and Ukraine are poised to sign an agreement on rare earth minerals "and other things" — or at least they were before a heated moment between him, Vice President JD Vance, and Ukrainian Ukrainian President Volodymyr Zelenskyy in the Oval Office on Friday.

The president-elect's undiplomatic talk in recent days of reclaiming the Panama Canal — and annexing Greenland and even Canada — have some experts comparing his strategy to Nixon's "Madman Theory."

They are found in everyday tech devices, and China controls a huge part of the market.
