Interface Between MTA and Dental Bonding Agents: Scanning Electron Microscope Evaluation
Journal of International Society of Preventive and Community Dentistry, 2017 Aims and Objectives: Nowadays, the material that offers the best sealing characteristic in the field of endodontic treatment is the mineral trioxide aggregate (MTA), nevertheless, this material necessities an adhesive bonding agent to perfectly join to ...

A fluorescence scanning electron microscope
Ultramicroscopy, 2009 Fluorescence techniques are widely used in biological research to examine molecular localization, while electron microscopy can provide unique ultrastructural information. To date, correlative images from both fluorescence and electron microscopy have been obtained separately using two different instruments, i.e.

A Simple Scanning Electron Microscope [PDF]
Review of Scientific Instruments, 1969 A simple scanning microscope has been built which uses a field emission electron gun alone, without the aid of auxiliary lenses. The design and operation of the microscope are described and the calculated performance is compared with experiment. Resolution of 100 Å has been obtained and is shown in transmission electron micrographs.

Closed-Loop Autofocus Scheme for Scanning Electron Microscope
MATEC Web of Conferences, 2015 In this paper, we present a full scale autofocus approach for scanning electron microscope (SEM). The optimal focus (in-focus) position of the microscope is achieved by maximizing the image sharpness using a vision-based closed-loop control scheme.

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

Research 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 ...

Scan Coil Dynamics Simulation for Subsampled Scanning Transmission Electron Microscopy [PDF]
arXiv, 2023 Subsampling and fast scanning in the scanning transmission electron microscope is problematic due to scan coil hysteresis - the mismatch between the actual and assumed location of the electron probe beam as a function of the history of the scan. Hysteresis limits the resolution of the microscope and can induce artefacts in our images, particularly ...
