Exploring leakage in dielectric films via automated experiment in scanning probe microscopy [PDF]
, 2021 Electronic conduction pathways in dielectric thin films are explored using automated experiments in scanning probe microscopy (SPM). Here, we use large field of view scanning to identify the position of localized conductive spots and develop a SPM workflow to probe their dynamic behavior at higher spatial resolution as a function of time, voltage, and ...

Phase imaging in scanning transmission electron microscopy using bright-field balanced divergency method [PDF]
Ultramicroscopy 245 (2023): 113665, 2023 We introduce a phase imaging mechanism for scanning transmission electron microscopy that exploits the complementary intensity changes of transmitted disks at different scattering angles. For scanning transmission electron microscopy, this method provides a straightforward, dose-efficient, and noise-robust phase imaging, from atomic resolution to ...

Comparative scanning electron microscopy of bullous diseases [PDF]
Anais Brasileiros de Dermatologia, 2014 The purpose of this study is to compare scanning electron microscopy findings of the blister roof in three distinct bullous diseases: one intraepidermal acantholytic (pemphigus foliaceus); one due to hemidesmosomal dysfunction (bullous pemphigoid); and ...

Scanning ultrafast electron microscopy [PDF]
Proceedings of the National Academy of Sciences, 2010 Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode.

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 ...

Transmission and scanning electron microscopy of cutis rhomboidalis
Anais Brasileiros de Dermatologia, 2021 Cutis rhomboidalis nuchae was assessed in a 65-year-old patient. Optical microscopy showed basophilic agglomerations in the reticular dermis with decreased elastic fibers.

Flash Scanning Electron Microscopy [PDF]
, 2013 Scanning Electron Microscopy (SEM) is an invaluable tool for biologists and neuroscientists to study brain structure at the intracellular level. While able to image tissue samples with up to 5 nm isotropic resolution, image acquisition is prohibitively slow and limits the size of processed samples.

Cryoprotection of porcine cornea: a scanning electron microscopy study
Veterinární Medicína, 2005 Porcine corneas were frozen with Me2SO, glycerol, 1,2-propanediol and PEG-400. The effects of the range of concentrations (5% and 10%) and temperature regimen (1ºC/min and 5ºC/min) were investigated.
