How catalysts age

"Our new, detailed results could help industrial companies optimise their catalysts and make them more durable"

11-Jun-2021

PSI researchers have developed a new tomography method with which they can measure chemical properties inside catalyst materials in 3D extremely precisely and faster than before. The application is equally important for science and industry. The material group of vanadium phosphorus oxides (VPOs) ...

'Flipped' metal oxide cage can sort CO2 from CO

Spherical vanadium oxide clusters that can trap and hold carbon dioxide

10-Jan-2019

How do you separate carbon dioxide from carbon monoxide? One way, showcased by a new study from Kanazawa University, is to use a bowl of vanadium. More precisely, a hollow, spherical cluster of vanadate molecules can discriminate between CO and CO2, allowing potential uses in CO2 storage and ...

Developing new materials for the fusion reactor

Success in developing vanadium alloys strong at high temperatures

11-Dec-2018

In the future fusion reactor, plasma is confined by using the magnetic field inside the doughnut-shaped vacuum vessel. The blanket is in a location where it almost touches the plasma, and as if to enfold the plasma the blanket is placed on the inner surface of the vacuum chamber. The blanket, by ...

Disordered materials could be hardest, most heat-tolerant carbides

Simulations predict new class of carbides

28-Nov-2018

Materials scientists at Duke University and UC San Diego have discovered a new class of carbides expected to be among the hardest materials with the highest melting points in existence. Made from inexpensive metals, the new materials may soon find use in a wide range of industries from machinery ...

Disorder plays a key role in phase transitions of materials

06-Nov-2018

Phase transitions are common occurrences that dramatically change the properties of a material, the most familiar being the solid-liquid-gas transition in water. Each phase corresponds to a new arrangement of the atoms within the material, which dictate the properties of the substance. While ...

Rutgers-led research could lead to more efficient electronics

07-Jun-2018

A Rutgers-led team of physicists has demonstrated a way to conduct electricity between transistors without energy loss, opening the door to low-power electronics and, potentially, quantum computing that would be far faster than today's computers. Their findings, which involved using a special mix ...
