In autonomous vehicle systems, millimeter-wave (mmWave) automotive radars are promising candidates for object detection. These systems include key components such as a signal-processing electronic circuit, a transmitter, and an mmWave receiver. The graphyne (GY) family ($alpha$-, $beta$-, and $gamma$ -GY) can represents a novel class of two-dimensional carbon allotropes that may serve as promising candidates for mmWave receivers; however, their attributes need to be evaluated for this application. In this regard, the present study aims to investigate the bending stiffness, stretching behavior, resonant frequencies, and mechanical stability of GY-based materials, as well as their interaction with mmWave in terms of their applicability as receiver materials. To achieve these goals, a hybrid approach combining continuum mechanics-based theory and molecular dynamics simulations is employed in addition to solving Maxwell's equations. The outcomes highlight the potential of GY sheets for object visualization within the frequency band of U (40-60 GHz), E (60-90 GHz), and D (110-170 GHz) for $alpha$ -GY; the F (90-140 GHz), V (50-75 GHz), and W (75-110 GHz) for $beta$ -GY; and the V (50-75 GHz), W (75-110 GHz), and Q (30-50 GHz) for $gamma$-GY. An inverse relationship is observed between mmWave absorption and mechanical stability, with the absorption capability following $alpha$-GY $>$$beta$-GY $>$$gamma$-GY. Moreover, with respect to vibrational modes, the order follows the same sequence as the absorption capability.

2-Butanone is a common colorless, flammable volatile organic compound (VOC) in chemical, electronics, new energy, and petroleum fields. However, its hazards to human health and its danger as a raw material for crystal methamphetamine production underscore the high necessity for developing detection technologies targeting it. In this study, Ni-doped ZnO was synthesized from a ZIF-8 derivative precursor for gas sensing applications.The phase composition, microstructure, and elemental chemical states of the samples were characterized by XRD, SEM, TEM, and XPS. Gas sensing tests showed that Ni doping reduced the optimal operating temperature from 320 °C for pure ZnO to 300 °C. The Ni-doped ZnO exhibited a significantly enhanced response (Ra/Rg = 287.5) to 100 ppm 2-butanone at 300 °C, along with excellent selectivity and repeatability. Furthermore, the sensor achieved effective detection of 2-butanone at concentrations as low as 0.1 ppm (Ra/Rg = 2.5). This study confirms that utilizing ZIF-8 as a precursor combined with Ni doping is an effective strategy for enhancing the detection performance of ZnO-based sensors for 2-butanone, providing a viable direction for developing high-sensitivity metal oxide (MOX) gas sensors.
