From zirconia to yttria: Sampling the YSZ phase diagram using sputter-deposited thin films

open access: yesAIP Advances, 2016
Yttria-stabilized zirconia (YSZ) thin films with varying composition between 3 mol% and 40 mol% have been prepared by direct-current ion beam sputtering at a substrate temperature of 300 °C, with ideal transfer of the stoichiometry from the target to the

A Deep Learning Approach to Identify Local Structures in Atomic‐Resolution Transmission Electron Microscopy Images [PDF]

open access: yesAdvanced Theory and Simulations, 2018
Recording atomic‐resolution transmission electron microscopy (TEM) images is becoming increasingly routine. A new bottleneck is then analyzing this information, which often involves time‐consuming manual structural identification.

Is Small Perfect? Size Limit to Defect Formation in Pyramidal Pt Nanocontacts [PDF]

open access: yes, 2007
We report high resolution transmission electron microscopy and ab initio calculation results for the defect formation in Pt nanocontacts (NCs). Our results show that there is a size limit to the existence of twins (extended structural defects).

Quality of extracellular vesicle images by transmission electron microscopy is operator and protocol dependent

open access: yesJournal of Extracellular Vesicles, 2019
Transmission electron microscopy (TEM) has nanometre resolution and can be used to distinguish single extracellular vesicles (EVs) from non-EV particles. TEM images of EVs are a result of operator image selection. To which extent operator image selection

Scanning Transmission Electron Microscopy

open access: yesDefinitions, 2020
The scanning transmission electron microscope () has become one of the preeminent instruments for high spatial resolution imaging and spectroscopy of materials, most notably at atomic resolution. The principle of STEM is quite straightforward.

Biomass derived mesoporous carbon monoliths via an evaporation-induced self-assembly [PDF]

open access: yes, 2013
Evaporation-induced self-assembly has been applied in the synthesis of crack-free mesoporous carbon monolith with good mechanical stability using a waste plant material as carbon precursor and triblock copolymer F127 as template.
