Design of electrostatic phase elements for sorting the orbital angular momentum of electrons
Giulio Pozzi, Vincenzo Grillo, Peng-Han Lu +3
The orbital angular momentum (OAM) sorter is a new electron optical device for measuring an electron s OAM. It is based on two phase elements, which are referred to as the unwrappe…

Highly Deformable and Mobile Palladium Nanocrystals as Efficient Carbon Scavengers
Peng-Han Lu, De-Gang Xie, Bo-Yu Liu +7
Fouling of surfaces leads to performance degradation in many energy-intensive industrial processes, but the present solutions are either too complicated to be routinely used or inc…
