UT Dallas researchers use 2D MoS2 as protective layer for Li-metal anodes in Li-S batteries; extended cycle life

Green Car Congress

Researchers at The University of Texas at Dallas have used two-dimensional (2D) MoS 2 (molybdenum disulfide) as a protective layer for Li-metal anodes, greatly improving the performances of Li–S batteries. However, sulfur is a poor electrical conductor and can become unstable over just several charge-and-recharge cycles.

How the Graphical User Interface Was Invented

Cars That Think

It took some 30 years of effort by engineers and computer scientists in universities, government laboratories, and corporate research groups, piggybacking on each other’s work, trying new ideas, repeating each other’s mistakes. Menus list choices of action. But the development of today’s graphical user interface was anything but simple.

Designing the First Apple Macintosh: The Engineers’ Story

Cars That Think

Generally, a multitasking operating system tracks the progress of each of the programs it is running and then stores the entire state of each program—the values of its variables, the location of the program counter, and so on.
