Evaluating the efficacy of desensitizing dentifrices on dentinal hypersensitivity management: A scanning electron microscopic analysis

open access: yesJournal of Indian Society of Periodontology, 2021
Introduction: Dentin hypersensitivity (DH) adversely affects quality of life by impairing the ability to eat and drink certain foods, therefore, should be addressed promptly with a contingency plan that includes initial treatment with a noninvasive ...

Ultra-structural Observations of Colletotrichum orbiculare on Cucumber Leaves Pre-treated with Chlorella fusca

open access: yesResearch in Plant Disease, 2017
Chlorella is one of the microorganisms which can live autotrophically by their own photosynthesis. It was previously revealed that pre-treatment of Chlorella fusca caused a suppression of appressorium formation on the cucumber leaves after inoculation ...

Mechanical scanning of the specimen in the scanning electron microscope [PDF]

open access: yesScanning, 2004
AbstractA scanning electron microscope (SEM) system equipped with a motor drive specimen stage fully controlled with a personal computer (PC) has been utilized for obtaining ultralow magnification SEM images. This modern motor drive stage works as a mechanical scanning device.

Scanning Electron Microscope: Advantages and Disadvantages in Imaging Components

open access: yes, 2017
An account of the early history of SEM has been presented by McMullan (1988 and 2006) Although Max Knoll produced a photo with a 50 mm object-field-width showing channeling contrast by the use of an electron beam scanner, (Knoll, 1935) it was Manfred von

High-resolution, high-throughput imaging with a multibeam scanning electron microscope

open access: yesJournal of Microscopy, 2015
Electron–electron interactions and detector bandwidth limit the maximal imaging speed of single‐beam scanning electron microscopes. We use multiple electron beams in a single column and detect secondary electrons in parallel to increase the imaging speed

Nitrogen implantation with a scanning electron microscope [PDF]

open access: yesScientific Reports, 2018
AbstractEstablished techniques for ion implantation rely on technically advanced and costly machines like particle accelerators that only few research groups possess. We report here about a new and surprisingly simple ion implantation method that is based upon a widespread laboratory instrument: The scanning electron microscope.

Formation of Three-Way Scanning Electron Microscope Moiré on Micro/Nanostructures

open access: yesThe Scientific World Journal, 2014
Three-way scanning electron microscope (SEM) moiré was first generated using a designed three-way electron beam (EB) in an SEM. The spot-type three-way SEM moiré comes from the interference between the three-way EB and the specimen grating in which the ...

Nanotip electron gun for the scanning electron microscope [PDF]

open access: yesScanning, 2005
Experimental nanotips have shown significant improvement in the resolution performance of a cold field emission scanning electron microscope (SEM). Nanotip electron sources are very sharp electron emitter tips used as a replacement for the conventional tungsten field emission (FE) electron sources.

Microleakage of different provisionalization techniques for class I inlays

open access: yesJournal of Dental Sciences, 2013
Background/purpose: To investigate the effects of different provisionalization methods on the microleakage of class I inlay cavities. Materials and methods: Class I inlay cavities were prepared on human molars (n = 60). Teeth were divided into six groups

A scanning electron microscope for ultracold atoms [PDF]

open access: yesLaser Physics Letters, 2006
We propose a new technique for the detection of single atoms in ultracold quantum gases. The technique is based on scanning electron microscopy and employs the electron impact ionization of trapped atoms with a focused electron probe. Subsequent detection of the resulting ions allows for the reconstruction of the atom's position.
