Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside ...

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 ...

A computer-assisted design schematic showing how an electron beam is routed within a microscope. After going through the sample, it crosses a bright cyan beam representing the laser beam. A schematic ...

For decades, a laboratory procedure known as transmission electron microscopy (TEM) has been used to test for asbestos in samples taken at construction sites. In 1989, the U.S. Environmental ...
