Hexagonal boron nitride's remarkable toughness unmasked

It's official: Hexagonal boron nitride (h-BN) is the iron man of 2D materials, so resistant to cracking that it defies a century-old theoretical description engineers still use to measure toughness.

Zero-carbon energy from seawater now a step closer

Researchers at McGill University have demonstrated a technique that could enable the production of robust, high-performance membranes to harness an abundant source of renewable energy.

Unveiling what governs crystal growth

With brilliant colors and picturesque shapes, many crystals are wonders of nature. Some crystals are also wonders of science, with transformative applications in electronics and optics. Understanding how best to grow such ...

New tech builds ultralow-loss integrated photonic circuits

Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications. With an incredibly low loss of 0.2 dB/km, optical fibers made from silica have laid the foundations of ...

Heat conduction record with tantalum nitride

A thermos bottle has the task of preserving the temperature—but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed. ...
