Understanding alkali contamination in colloidal nanomaterials to unlock grain boundary impurity engineering
Se-Ho Kim, Su-Hyun Yoo, Poulami Chakraborty +10
Metal nano-aerogels combine a large surface area, a high structural stability, and a high catalytic activity towards a variety of chemical reactions. The performance of such nanost…
Automated crystal orientation mapping by precession electron diffraction assisted four-dimensional scanning transmission electron microscopy (4D-STEM) using a scintillator based CMOS detector
Jiwon Jeong, Niels Cautaerts, Gerhard Dehm +1
The recent development of electron sensitive and pixelated detectors has attracted the use of four-dimensional scanning transmission electron microscopy (4D-STEM). Here, we present…
Investigation of the orientation relationship between nano-sized G-phase precipitates and austenite with scanning nano-beam electron diffraction using a pixelated detector
Niels Cautaerts, Edgar F. Rauch, Jiwon Jeong +2
Scanning nano-beam electron diffraction with a pixelated detector was employed to investigate the orientation relationship of nanometer sized, irradiation induced G-phase (MNi$…
The interfacial spin modulation of graphene on Fe(111)
J. Hong, H. -N. Hwang, A. T. NDiaye +13
When Fe, which is a typical ferromagnet using d- or f-orbital states, is combined with 2D materials such as graphene, it offers many opportunities for spintronics. The origin of 2D…
