aInverters use advanced power switching semiconductors (you might hear them called IGBTs) and microprocessor controls that operate thousands of times faster than "conventional" power switching devices and controls. As a result, inverters push the arc through the zero crossing very quickly. This very...
Most discussions of industrial policy in the U.S. focus on semiconductors, batteries, or electric vehicles. But there’s an incredibly important industry where the U.S.has fallen badly behind, and where its deficiencies could cost the U.S. Military its edge over China. I’m talking aboutdro...
aLater, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDs he invented in 1962 now last about 10 times longer than incandescent bulbs, and are...
However, after being put in contact with the physiological environment, these grafting materials were surrounded by a fibrous capsule of scar tissue that compromised their integration with the host tissue. After listening to some studies about gamma rays applied to vanadia-phosphate semiconductors ...
