Over the past few years we’ve seen several impressive projects where people try to manufacture integrated circuits using hobbyist tools. One of the most complex parts of this process is lithography: ...

Electron beams have transcended their traditional roles in imaging and lithography to become vital platforms for exploring fundamental quantum phenomena. Central to recent advances is the manipulation ...

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for ...

Back in 2010, crystallographer Tim Gruene heard a scientist from drugmaker Novartis say something that stuck with him. The pharmaceutical giant had amassed a collection of around 2 million small ...

A new way of imaging frozen biological samples using electron microscopy is providing new glimpses into the nanoscopic world of cells. Images reveal bent in-vitro tubulin microtubules next to and in a ...

You’ve probably seen Lichtenberg figures before, those lightning-like traces left by high-voltage discharge. The safe way to create them is using an electron beam to embed charge inside an ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed and tested the world's highest voltage polarized electron gun, a key piece of technology needed for ...

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 ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds ...
