Optical characterization of the synthesized AA-stacked hBN revealed enhanced second-harmonic generation (SHG)—a hallmark of non-centrosymmetric crystal structures—indicating promising applications in nonlinear optics. Additionally, the material exhibited sharp band-edge emission in the DUV region, suggesting its potential for high-efficiency optoelectronic devices operating in the DUV spectrum.

Researchers at Westlake University have disclosed a two-dimensional (2D) mechanically interlocked polymer (MIP) that mimics medieval chainmail at the molecular scale. This micrometer-scale 2D material exhibits exceptional flexibility and stiffness, potentially revolutionizing next-generation lightweight protective gear and smart armor systems.

This development holds significant promise for applications that involve sudden or extreme temperature changes, such as rocket or jet engines, automotive exhaust systems, power plant turbines, and pipelines. The alloy’s ability to maintain stable performance under such conditions can greatly enhance both safety and efficiency in these demanding environments.

In metals, perfect crystals are weak. The regular patterns of perfect crystals make it easier for the atoms to slip past each other. When that happens, the metal bends, stretches or breaks. Quasicrystals break up the regular pattern of the aluminum crystals, causing defects that make the metal stronger.

In twisted moiré photonic crystals, how the layers twist and overlap can change how the material interact with light. By changing the twist angle and the spacing between layers, these materials can be fine-tuned to control and manipulate different aspects of light simultaneously — meaning the multiple optical components typically needed to simultaneous measure light’s phase, polarization, and wavelength could be replaced with one device.
