Moore's law is hitting a wall, so researchers are stacking silicon chip layers instead of shrinking them

University of Illinois team stacks three active silicon layers on a single chip, achieving 98-100% transistor yield
Forward-looking: For years, the chip industry has chased better performance by shrinking transistors and squeezing more of them onto a flat slice of silicon. That strategy is running into hard limits. A group at the University of Illinois thinks the next gains will come not from going smaller, but from going vertical.

This ultra-cheap, water-based iron battery could last 16 years without degrading

The all-iron flow battery completed 6,000 cycles with no measurable capacity loss
Forward-looking: Lithium-ion batteries are everywhere, but their cost, supply chain issues, and potential to fail in fiery ways make them less than ideal for grid-scale energy storage. Chinese researchers say they have taken a major step toward an alternative in the form of an all-iron flow battery built from cheap, abundant materials and a water-based electrolyte that cannot explode.
