Scanning Electron Microscopy Observations of Loa loa (Nematoda)
Case Reports in Ophthalmology, 2020 We present a case report of periocular Loa loa. The key feature of L. loa distinguishing it from other human filarial parasites are cuticular bosses, which are presented in images from a light microscope and a scanning electron microscope.

Scanning electron microscopy image representativeness: morphological data on nanoparticles. [PDF]
, 2017 A sample of a nanomaterial contains a distribution of nanoparticles of various shapes and/or sizes. A scanning electron microscopy image of such a sample often captures only a fragment of the morphological variety present in the sample.

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 ...

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.

Spin-polarized scanning electron microscopy [PDF]
Microscopy, 2005 Spin-polarized scanning electron microscopy (spin-SEM) is a magnetic domain observation method. In spin-SEM, polarization of secondary electrons emitted from a sample in a scanning electron microscope is detected by a spin detector and used as a signal for forming an image. The characteristics of spin-SEM are detection of all three magnetization vector

Low voltage scanning electron microscopy [PDF]
Journal of Microscopy, 1984 SUMMARYThe scanning electron microscope (SEM) is usually operated with a beam voltage, V0, in the range of 10–30 kV, even though many early workers had suggested the use of lower voltages to increase topographic contrast and to reduce specimen charging and beam damage. The chief reason for this contradiction is poor instrumental performance when V0=1–3

The first annotated set of scanning electron microscopy images for nanoscience
Scientific Data, 2018 In this paper, we present the first publicly available human-annotated dataset of images obtained by the Scanning Electron Microscopy (SEM). A total of roughly 22,000 SEM images at the nanoscale are classified into 10 categories to form 4 labeled ...
