Electron scattering in atomic force microscopy experiments [PDF]

, 2005
It has been shown that electron transitions, as measured in a scanning tunnelling microscope (STM), are related to chemical interactions in a tunnelling barrier.

Multi-step atomic mechanism of platinum nanocrystals nucleation and growth revealed by in-situ liquid cell STEM

Scientific Reports, 2021
The understanding of crystal growth mechanisms has broadened substantially. One significant advancement is based in the conception that the interaction between particles plays an important role in the growth of nanomaterials.

Realization of aligned three-dimensional single-crystal chromium nanostructures by thermal evaporation [PDF]

, 2010
Aligned three-dimensional single-crystal chromium nanostructures are fabricated onto a silicon substrate by thermal evaporation in a conventional thermal evaporator, where the incident angle of Cr vapor flux with respect to the substrate surface normal ...

SCANNING ELECTRON MICROSCOPY [PDF]

Journal of the Royal Microscopical Society, 1964
Abstract Scanning electron microscopy is a method of microscopy that permits resolution better than that of the optical microscope (about 100 A) while examining one surface of a bulk specimen. The technique depends on electronic application to microscopy and has been developed over many years by electronic engineers rather than physicists or ...

Endocytosis-like DNA uptake by cell wall-deficient bacteria

Nature Communications, 2022
Horizontal gene transfer in bacteria can occur through mechanisms such as conjugation, transduction and transformation, which facilitate the passage of DNA across the cell wall. Here, Kapteijn et al. show that cell wall-deficient bacteria can take up DNA

Cathodoluminescence of stacking fault bound excitons for local probing of the exciton diffusion length in single GaN nanowires [PDF]

, 2014
We perform correlated studies of individual GaN nanowires in scanning electron microscopy combined to low temperature cathodoluminescence, microphotoluminescence, and scanning transmission electron microscopy.

Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]

, 2010
Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...

Scanning electron microscopy of cold gases

, 2015
Ultracold quantum gases offer unique possibilities to study interacting many-body quantum systems. Probing and manipulating such systems with ever increasing degree of control requires novel experimental techniques. Scanning electron microscopy is a high

Does drying affect gel networks? [PDF]

, 2018
The properties of low molecular weight gels are determined by the underlying, self-assembled network. To access information on the network, it is common for techniques to be used that require the gel to be dried, such as transmission electron microscopy ...
