Using diamond microparticles to create high security anti-counterfeit labels hkuniversity NatureComms
. For example, some AI algorithms could be applied for the rapid and accurate authentication of the diamond-PUFs by comparing the “fingerprint” of shape features and light scattering spectra of the diamond particles. Furthermore, actual perturbations must be considered in practical applications. Therefore, robust AI-assisted authentication is critical for practical usage.
In summary, we propose and demonstrate an advanced anti-counterfeiting material, i.e., diamond microparticles with SiV centers on Si wafer by CVD fabrication. Our findings offer the welcome prospect of the immediate development of a robust, dynamic, trustworthy, and intelligent anti-counterfeiting strategy. The PUF nature of the light scattering patterns, spectra, shape, and the SiV PL intensity of the diamond microparticles offer high-capacity static encoding.

Mammalian maxilloturbinal evolution does not reflect thermal biology - Nature CommunicationsThe maxilloturbinal, an area of the mammalian nasal cavity, has been proposed to play a pivotal role in body temperature maintenance. Here, the authors use computed tomographic data to show that neither corrected basal metabolic rate nor body temperature significantly correlate with the relative surface area of the maxilloturbinal.
