The exact birth of the scanning microscope principle is not clear, as the work of numerous scientists contributed to its inception. However, it is generally accepted that the first scanning microscope ...

Have you ever seen a hibiscus flower? Although its petals have a range of colors, what makes the trumpet-shaped flower more ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

The kidneys are vital organs that sustain life by filtering the blood and producing urine. This filtration process takes ...

The Thermo Fisher Apreo 2 Variable Pressure Field Emission Scanning Electron Microscope (FE-SEM) is a thermionic field emission high-resolution scanning electron microscope. The Apreo 2 FE-SEM is an ...

Transmission electron microscopy (TEM) has long been the gold standard for detecting asbestos fibers in air samples drawn at construction sites. But researchers have found that a cheaper, less ...

Atoms measure roughly 0.1 nanometers across, a scale so small that scientists spent more than six decades developing instruments capable of resolving them with any clarity. The journey from the first ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Beam-sensitive zeolites are difficult to study at high resolution because traditional electron microscopy often damages or destroys their delicate crystal structures before meaningful data can be ...
