SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950s, scanning electron microscopes ...

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

How flu viruses enter cells has been directly observed thanks to a new microscopy technique with the potential to revolutionize research on membrane biology, virus–host interactions and drug discovery ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

Since the first transmission electron microscope was sold in 1935, microscopes that use electrons--rather than light waves--to image objects have brought into focus levels of detail that were ...

The FEI Philips XL 40 Environmental Scanning Microscope (ESEM) is a large-chamber, tungsten source, environmental scanning electron microscope capable of high and low vacuum imaging. The FEI Philips ...

Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.
