Using a ceramic, rather than a plastic package, Cree allows SSL designers to pack mid-power LEDs more closely while delivering more light. Cree has announced the new XLamp XQ family of mid-power LEDs that are built using the same ...
Theoretical physicist Michio Kaku believes Moore's Law has about 10 years of life left before ever-shrinking transistor sizes smack up against limitations imposed by the laws of thermodynamics and quantum physics. That day of reckoning ...

Simulations reveal that the formation of some glassy materials is like the setting of a bowl of gelatin. Gelatin sets by forming a solid matrix full of random, liquid-filled pores — much like a saturated sponge. It turns out that a ...
Any new toy that wants to get its product into retail needs to appreciate that they will not be alone. Retail buyers are inundated with calls from start-ups, inventors and product designers, almost daily. To get noticed you really need a ...
