Abstract: Hitachi Lab-in-Gap transmission electron microscopy (TEM) technologies are introduced. The term Lab-in-Gap refers to a special function that allows in situ and in operando TEM studies of materials in gas or liquid environments while stimulations, such as thermal or electrical fields, are applied to the specimen sitting in the pole piece gap in a TEM system. Physical or chemical process can be activated and imaged in real time using TEM or other imaging modes. The new generation environmental TEM platform with large pole piece gap and advanced aberration correctors opens wide possibilities for integrating multiple stimuli sources as well as large-area, sub-Å resolution live imaging for dynamic structural changes.

Fluorescence microscopy has employed mercury arc lamps for decades because of their high power and broad spectrum. Fluorophores and filter sets have been developed around the peaks of the spectrum offered by these lamps. When LEDs first entered the fluorescence microscopy arena, prices were high and output was low, but in recent years there have been significant advancements in LED capabilities for microscopy. This article aims to educate users of fluorescence microscopy about the benefits of LEDs compared to conventional mercury arc lamps.
