New Self-Assembled Silicon-Carbon Nanocomposite Anodes for Li-ion Batteries Offer More Than 5X The Reversible Capacity of Graphite Anodes

Green Car Congress

The synthesis process is simple, low-cost, safe and broadly applicable, they say, providing new avenues for the rational engineering of electrode materials with enhanced conductivity and power. This is a significant step toward commercial production of silicon-based anode materials for lithium-ion batteries. Resources.

How the Graphical User Interface Was Invented

Cars That Think

In 1984, the low-cost Macintosh from Apple Computer Inc., tested all the commercially available pointing devices, from the still-popular light pen to a joystick and a Graphicon (a curve-tracing device that used a pen mounted on the arm of a potentiometer). Cupertino, Calif., were derivatives of those in Appleā€™s Lisa and Mac.
