Transmission electron microscopy of thiol-capped Au clusters on C: Structure and electron irradiation effects
(Elsevier, 2015)
High-resolution transmission electron microscopy is used to study interactions between thiol-capped Au clusters and amorphous C support films. The morphologies of the clusters are found to depend both on their size and on ...

Removing the effects of the “dark matter” in tomography
(Elsevier, 2015)
Electron tomography (ET) using different imaging modes has been progressively consolidating its position as a key tool in materials science. The fidelity of a tomographic reconstruction, or tomogram, is affected by several ...

Tomographic Heating Holder for In Situ TEM: Study of Pt/C and PtPd/Al2O3 Catalysts as a Function of Temperature
(Cambridge University Press, 2014)
A tomographic heating holder for transmission electron microscopy that can be used to study supported catalysts at temperatures of up to ~1,500°C is described. The specimen is placed in direct thermal contact with a tungsten ...

Strong quantum confinement effects in SnS nanocrystals produced by ultrasound-assisted method
(Springer, 2013)
Nanocrystalline SnS powder has been prepared using tin chloride (SnCl2) as a tin ion source and sodium sulfide (Na2S) as a sulfur ion source with the help of ultrasound irradiation at room temperature. The as-synthesized ...

Direct observation of doping incorporation pathways in self-catalytic GaMnAs nanowires
(American Institute of Physics, 2015)
Doping mechanisms of Mn in GaAs nanowires (NWs) that have been grown self-catalytically at 600 C by molecular beam epitaxy (MBE) are investigated using advanced electron microscopy techniques and atom probe tomography. Mn ...

Transmission electron microscopy of unstained hybrid Au nanoparticles capped with PPAA (plasma‐polyallylamine): structure and electron irradiation effects
(Elsevier, 2014)
Hybrid (organic shell–inorganic core) nanoparticles have important applications in nanomedicine. Although the inorganic components of hybrid nanoparticles can be characterized readily using conventional transmission electron ...
