Before silicon got its own valley, this mild-mannered element had to vanquish many other contenders to prove itself the premier semiconductor technology. It did so in the 1950s and 1960s. Today, carbon is poised at a similar crossroads, with carbon-based technologies on the verge of transforming computing and boosting battery-storage capacities. Already, researchers have used these technologies to demonstrate paper-thin batteries, unbreakable touch screens, and terabit-speed wireless communications. And on the farther horizon they envision such carbon-enabled wonders as space elevators, filters that can make seawater drinkable, bionic organs, and transplantable neurons.

Whatever miracles emerge from Carbon Valley, its carbon-tech titans will surely think fondly upon their field's founding mother, Mildred Dresselhaus. This MIT professor of physics and engineering has, since the early 1960s, been laying the groundwork for networks of nanometer-scale carbon sheets, lattices, wires, and switches. Future engineers will turn these things, fabricated from carbon-based materials such as graphene, into the systems that will carry computing into its next era.

Vanadium Anodes for Faster-charging, Longer-lived Batteries

Startup TyFast aims for 3-minute charging, 20,000-cycle life

Startup Tyfast is making batteries based on a new anode material that allow it to charge in minutes and last for several thousands of charge cycles

Tyfast

To fulfill the vision of EVs that travel a thousand miles or phones that run for days on a single charge, most battery developers are racing to make batteries that can pack twice the energy in the same weight.

Not startup Tyfast, which is “approaching next-generation battery development in a counter-current direction,” says GJ la O’, CEO and cofounder of the 2021 spinoff from the University of California, San Diego.

IEEE STEM Activity Kits Are In Demand at 150 U.S. Public Libraries

Kids can build robots, write code, and design video games

Two boys and one girl standing in front of a computer monitor. On the left side of the monitor is a backpack containing a science activity kit.

These youngsters are checking out one of their local library’s IEEE-funded science activity kits.

John Zulaski

More than 150 public libraries throughout the central United States now lend out activity kits that let children explore just about any aspect of science, technology, engineering, and mathematics. The kids can check them out just like they would a book. The kits teach youngsters what engineers do, as well as how to code, build robots, design video games, and create animations.

The collections have been made possible by the IEEE Region 4 Science Kits for Public Libraries program with funding from Region 4 members and corporate sponsors. The SKPL program is the brainchild of IEEE Life Senior Member John A. Zulaski, the chair of the SKPL committee.
