Summary: This study investigates the use of green-mediated copper oxide nanoparticles as a corrosion inhibitor for dental alloy Ti-6Al-4V. The copper salt was reduced to metal nanoparticles using Murraya koenigii leaves, resulting in agglomeration and nanocluster formation. The synthesized nanoparticles were then characterized and electrodeposited on the alloy, and their corrosion resistivity in a dental medium was analyzed. The study confirms the advantage of using these nanoparticles as a coating agent in dental implant alloys to enhance corrosion efficiency.

Summary: The study demonstrated that the methanolic extract of Clerodendrum serratum had an anti-fertility effect on mature male rats, resulting in reduced fertility in female rats that mated with treated male rats. This effect was shown through changes in testicular cholesterol and ascorbic acid concentration, as well as reductions in reproductive hormones and enzyme levels. These findings support the traditional use of this plant as a male contraceptive in the Indian subcontinent.

Numerical calculations and experimental research were conducted, and a thermal-stress coupled finite element model was established. The results show that as the laser energy density increases, the removal rate of CuO particles initially increases and then decreases, while the roughness of the silicon substrate decreases and then increases.

Summary: This study investigates the AlN nucleation layer issue in GaN high frequency telecommunication and power switching systems fabricated after heteroepitaxy on Silicon or Silicon Carbide. It is shown that using 3C-SiC as an intermediate layer can significantly decrease RF propagation losses. Measurements and analyses demonstrate that dopant diffusion into the 3C-SiC pseudo-substrate is confined beneath the interface, and a slightly conductive zone is present beneath the AlN/3C-SiC interface, explaining the low propagation losses obtained for the devices. This work highlights the importance and efficiency of the 3C-SiC intermediate layer as a pseudo-substrate.

The researchers found that the Au/Ta2O5/GaN devices prepared on Ta2O5/GaN heterojunction with post-annealing exhibited improved photoresponsivity, EQE, and rise/fall times. This improvement is attributed to the optimized band configuration of the Ta2O5/GaN heterostructure and the effect of post-annealing on photogenerated charge carriers.
