• Silver just solved a major solid-state battery problem
  Solid-state batteries could store more energy and charge faster than today’s batteries, but they tend to crack and fail over time. Stanford researchers found that a nanoscale silver treatment can greatly strengthen the battery’s ceramic core. The silver helps seal tiny flaws and prevents lithium from causing further damage. This simple approach could help unlock next-generation batteries.
• Engineers just created a “phonon laser” that could shrink your next smartphone
  Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can produce ultra-fast surface waves that already play a hidden role in smartphones, GPS systems, and wireless tech. Unlike today’s bulky setups, this single-chip device could deliver far higher performance using less power, opening the door to smaller, faster, and more efficient phones and wireless devices.
