previous laser diodes needed to be cooled with liquid nitrogen to work. The advent of semiconductor lasers and the parallel innovation of optically pure glass fibers meant that AT&T could finally ...

The "Sarco" capsule, which has never been used before, is presumably designed to allow a person sitting in a reclining seat inside to push a button that injects nitrogen gas into the sealed chamber.

"Laser technology isn't perfect for spider veins," adds Baumann. "It's good, but saline injections are often more effective." Liquid nitrogen still ... problem from the inside; it stimulates ...

Measuring tiny magnetic fields, such as those generated by brain waves, enables many new novel opportunities for medical ...

As part of the global effort to harness power from fusing plasma, scientists worked on the computer codes, engineering and physics for a new and unique fusion reactor: the SMall Aspect Ratio Tokamak.

But the other benefit of a direct-injection engine is to reduce the harmful nitrogen oxides ... main challenge with laser ignition lies with getting the laser light inside the cylinder itself.

Like atoms coming together to release their power, fusion researchers worldwide are joining forces to solve the world's ...

The spaceflyers also cannot purge nitrogen from their systems and avoid ... Polaris Dawn will also feature a new ...

Shortly after liftoff, the Dragon's pressure began to slowly lower while oxygen levels inside the cabin increased, helping purge nitrogen from ... been testing a new laser-based satellite ...

Nitrogen makes up about 78% of the Earth's atmosphere. Liquid nitrogen is very cold, so it is often used to freeze food. The boiling point of nitrogen is −196 °C, so liquid nitrogen is very ...

A federal judge is hearing testimony about Alabama's nitrogen gas executions as the state plans another using this method for inmate Carey Dale Grayson. Grayson's attorneys argue for a preliminary ...

Two hours into the flight, they had their first meals and began testing a new laser-based satellite ... while oxygen levels inside the cabin increased, helping to purge nitrogen from the crew ...
