Mechanism of Cobalt-Manganese Catalysts Deciphered

Combination of different methods was the key to success

22-Oct-2024 - The energy carrier hydrogen can be obtained from water by electrolysis. This works particularly well with Cobalt spinel electrocatalysts containing manganese. However, it was unclear why. Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are ...

Magnetic Vortices Defy Temperature Fluctuations

Common Magnetic Mineral is Reliable Witness to Earth's History

19-Apr-2016 - Magnetic nanovortices in magnetite minerals are reliable witnesses of the earth's history, as revealed by the first high-resolution studies of these structures undertaken by scientists from Germany and the United Kingdom. The magnetic structures are built during the cooling of molten rock and ...

Topological Insulators: Stacking Instead of Mixing

Research team improves the energy efficiency of topological insulators

20-Nov-2015 - The overheating of computer chips is a major obstacle to the development of faster and more efficient computers and mobile phones. One promising remedy for this problem could be a class of materials first discovered just a few years ago: topological insulators, which conduct electricity with less ...

A Breakthrough in Electron Microscopy

Scientists reconstruct third dimension from a single image

23-Sep-2014 - Imagine that you want to find out from a single picture taken of the front of a house, what the building looks like from behind, whether it has any extensions or if the brickwork is damaged, and how many rooms are in the basement. Sounds impossible? Not in the nanoworld. Scientists from Jülich ...

Potential future data storage at domain boundaries

Scientists discover polar domain walls in antiferroelectric materials

16-Jan-2014 - Storing more and more in an ever-smaller space – what sounds impossible is in fact just part of the daily routine in information technology, where for decades, increasing amounts of data have been successfully stored on media with ever higher densities. An international team, including ...

Researchers develop catalyst material for fuel cells

Platinum-nickel nano-octahedra save 90 % platinum

19-Jun-2013 - Efficient, robust and economic catalyst materials hold the key to achieving a breakthrough in fuel cell technology. Scientists from Jülich and Berlin have developed a material for converting hydrogen and oxygen to water using a tenth of the typical amount of platinum that was previously required. ...

Jülich Neutron Scientists Inaugurate Unique Device in the USA

European researchers obtain access to world’s strongest neutron source

09-Nov-2009 - A unique large-scale research device from Jülich went into operation in the USA. At the strongest neutron source in the world, the spallation source SNS in Oak Ridge, Tennessee, Forschungszentrum Jülich inaugurated a so-called neutron spin echo (NSE) spectrometer. The NSE spectrometer enables ...
