PolishEM: Image enhancement in FIB-SEM
(Oxford University Press, 2020-03)
We have developed a software tool to improve the image quality in focused ion beam-scanning electron microscopy (FIB-SEM) stacks: PolishEM. Based on a Gaussian blur model, it automatically estimates and compensates for the ...
Exploring the interior of cuticles and compressions of fossil plants by FIB-SEM milling and image microscopy
(Wiley Blackwell Publishing, Inc, 2017-07)
We present the first study of cuticles and compressions of fossilleaves by Focused Ion Beam Scanning Electron Microscopy(FIB-SEM). Cavities preserved inside fossil leaf compressionscorresponding to substomatal chambers ...
FIB analysis of fossils plant remains: Technical and experimental aspects
(Akadémiai Kiadó, 2018-11)
We present a comprehensive study about the technical aspects of the application of focused ion beam (FIB) to thestudy of cuticles and compressions of fossil leaves.The technique allowed us to cross section and image fossil ...
Microscopic investigation of pitting corrosion in plasma nitrided austenitic stainless steelMikroskopische Untersuchung von Lochkorrosion an Plasmanitriertem austenitischem rostfreiem Stahl
(Carl Hanser Verlag, 2014-09)
UNS 31603 austenitic stainless steel was nitrided using different techniques, and pitting corrosion resistance was analysed in a chloride solution. All nitriding techniques, LEII, PI· and convectional DC nitriding produced ...
A Gas Sensor Based on a Single SnO Micro-Disk
(Mdpi, 2018-10-01)
In this study, individual nanofabricated SnO micro-disks, previously shown to exhibit exceptional sensitivity to NOx, are investigated to further our understanding of gas sensing mechanisms. The SnO disks presenting different ...
