Fuel cell technology has come a long way since the early days in the Apollo space program. Certainly the idea of running a car on pure hydrogen is an exciting prospect as the only emissions will be pure water.

But how much will you be willing to pay for this car? Current fuel cell technologies, need platinum (Pt) catalysts which are costly and insufficient for industry demand.Beside the high cost of platinum, another major drawback for commercialization of fuel cell technology is the sluggish oxygen reduction reaction (ORR) at cathode. Although, Pt and its alloys have been considered to be the most reliable cathodic ORR electrocatalysts in fuel cells, it also suffers from methanol crossover/carbon monoxide (CO) poisoning effects and poor long-term operation stability.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
