Electric eels generate voltage through long stacks of thin cells that run end-on-end through their bodies. Called electrocytes, these cells create electricity by allowing sodium ions to rush into one end and potassium ions out the other, all at the same time.
Breakthroughs Could Make Commercial Laser Nuclear Fusion Through Billion Times Improvements In Yield
A research paper claims experimentally confirmed reaction gains one billion times higher than the classical values, placing it far ahead any DT fusion approaches. Lasers are being demonstrated as more and more important in scientific research and in the access to new processes.
new holographic printing technique makes it possible to create the entire thing at once — in as little as a second or two, quickly producing the desired structure.
Researchers 3D-print WiFi-connected Objects That Don’t Need Power – The Objects Contain Antennas That Reflect Surrounding WiFi Signals.
“But the big challenge is how do you communicate wirelessly with WiFi using only plastic? That’s something that no one has been able to do before.” To do this, the team used things like 3D-printed springs, gears and switches that could be used to translate motion into antenna-transmitted information.
There are other differences. While traditional 3D printers build parts from computer files, the cold-spray machine uses digital scans of actual jet engine parts to accurately reconstruct the broken part.
n research described in the journal Nature Photonics, the Turkey-based researchers have developed a 3D laser fabrication technique that deliberately creates the conditions for exploiting these interactions, known as nonlinear feedback mechanisms.
