[Birdbrain] is trying to make their own microfluidic devices. To aid in this quest, they need a quality microscope to see what they’re doing. Instead of buying one outright, they purchased a cheap ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair.

Manipulating nanoscale light in scanning tunneling microscope junctions is attained by nanofabrication of gold tips using a focused ion beam technique. Researchers have demonstrated that a spectrum of ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

This relatively simple circuit uses a 6-V DC supply with a PWM current-source configuration to provide efficient, adjustable dimming of a white LED over a wide range, needed to accommodate the unique ...
