✦ Synopsis

We grew high-quality single crystals of an enhanced Pauli paramagnet NpGe 3 and measured the de Haas-van Alphen (dHvA) effect. The topology of the Fermi surfaces are well explained by the band calculations based on the 5f-itinerant band model. The cyclotron effective masses are ranging from 2.6 to 16m 0 , which are approximately 3.5 times enhanced from the corresponding band masses.

## Abstract The design and fabrication of various nanostructures with predefined geometry and composition is a big challenge of nanotechnology. Here we demonstrate an Au nanoflake film replicated from a self‐assembled, well‐ordered, dipeptide flower‐like hierarchical architecture. Such morphology c
