Inverse magnetic catalysis in field theory and gauge-gravity duality

, 2012
We investigate the surface of the chiral phase transition in the three-dimensional parameter space of temperature, baryon chemical potential and magnetic field in two different approaches, the field-theoretical Nambu-Jona-Lasinio (NJL) model and the ...

Unraveling the structure and role of Mn and Ce for NOx reduction in application-relevant catalysts

Nature Communications, 2022
The role of Ce one Mn-based catalysts for the selective catalytic reduction of NOx at low temperature is an ongoing debate. Here the authors demonstrate that Ce has a structural promoting effect but impacts negatively on the intrinsic catalytic activity ...
