There are two types of microscopes available: simple and compound microscopes. A simple microscope is equipped with one lens but a compound microscope has both an eyepiece and an objective lens.

The best microscopes for kids allow children to discover the world in miniature. As these naturally curious little scientists journey around the big wide world we see them inevitably become ...

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher ...

The caveat: due to sample damage only a single image can be collected from each crystal and interpreting the ... Microcrystal samples around 50nm are mounted onto a rotatable stage in a transition ...

explain modern methods in electron microscopy, electron diffraction, and spectroscopy. discuss the advantages and disadvantages of the different methods. describe the interaction between the inelastic ...

A unique requirement of near-field focused antennas is the requirement to characterize both transverse and axial resolution. We begin by revisiting the classical scalar Fresnel-Kirchhoffs diffraction ...

The paper provides a detailed explanation of how the profile of the light collected in a scanning tunneling microscope (STM ... that the light emitted by each electron tunneling with the right ...

Thanks to the diffraction limit, scientists could use the light microscope to see cells but not the proteins inside them or a virus attacking them. But there are optical microscopes today that can ...

A groundbreaking image of mouse brain tumor cells took top ... interacted.This took about three hours of precise observation under the microscope to capture the right moment, involving many ...

An electron microscope image of gold particles (yellow) on the graphene-chitosan sponge. “To the best of my knowledge, this is a record high value,” says Swiss Federal Institute of Technology ...
