The study was published today, July 24, in the journal Nutrients. It aims

Heat shield just 10 atoms thick to protect electronic devices: Atomically thin heat shields could be up to 50,000 times thinner than current insulating materials in cell phones and laptops

To guard against such ills, engineers often insert glass, plastic or even layers of air as insulation to prevent heat-generating components like microprocessors from causing damage or discomforting users. Now, Stanford researchers have shown that a few layers of atomically thin materials, stacked like sheets of paper atop hot spots,
