Hitachi High-Tech Corporation ("Hitachi High-Tech"), has launched the Ultrahigh-Resolution Scanning Electron Microscope SU9600, which allows for highly accurate and precise observation of substances ...
The National Institute for Materials Science (NIMS) and JEOL, Ltd. have developed a lanthanum hexaboride (LaB 6) nanowire-based field emission gun that is installable on an aberration-corrected ...
Vacuum sealed chamber that contains the field emission gun. A pneumatic valve seals the gun chamber in the event of an accidental vacuum vent. This prevents dust and debris from reaching the tip.
Scanning electron microscopy (SEM) has been an important tool for forensic science since the 1970s, and it continues to find forensic applications today. The technique – capable of 100,000x ...
