Most modern TEM electron guns use either a LaB6 filament or a field emission filament to obtain the desired brightness. The condenser lens also serves the same function in both the SEM and the TEM and therefore TEM condenser lenses are designed in the same way as SEM condenser lenses. Sign...
“Our analysis [in the lab] shows that the living contact lens is [not harmful to cells]; [Live] studies are needed to rule out irritation or other problems,” she said. In their paper, the researchers also note that future studies will help them understand variables like bacterial density...

By considering CHAT in relation to current theories in sustainability transitions (Sovacool and Hess, 2017), it may be possible to begin jointly developing insights and complementary lenses with an interest in integration. This review highlights how different sustainability-oriented lab conceptualizations ...
q is the total tube factor (zoom and other tube lenses), and ME = eyepiece lens magnification. For the case of detecting an image of a microscope which is projected onto an electronic sensor, such as that of a digital camera, the magnification for the image formed at the sensor is...
