A series of novel ethyl-7-（（1-（b.nzyl）-1H-1,2,3-triazol-4-yl）methoxy）-2-oxo-2H-chromene-3-carb.xylates 8a-h as potential antifungal agents were synthesized via click chemistry. The antifungal activity was evaluated against five human pathogenic fungal strains, such as Candida alb.cans, Fusarium oxysporum, Aspergillus flavus, Aspergillus niger and Cryptococcus neoformans. Compound 8c, 8d, 8e and 8h were found to b. equipotent against C. alb.cans when compared with miconazole and compound 8f was found to b. two-fold more active compared with miconazole and equipotent to fluconazole against ***. The coumarin-b.sed triazole derivatives were also evaluated for antioxidant activity and compound 8a was found to b. potent antioxidant when compared with standard dr.g. Furthermore,molecular docking study of the newly synthesized compounds was performed and results showed good b.nding mode in the active site of fungal C. alb.cans enzyme P450 cytochrome lanosterol 14 ademethylase. Moreover, the synthesized compounds were also analyzed for ADME properties and showed potential to b.ild up as good oral dr.g candidates.

In this study, a series of Gd^(3+)-doped mixed Ni-Cu-Zn ferrites with composition of Zn_(0.5)Ni_(0.3)Cu_(0.2)Fe_(2-x)Gd_(x)O_(4)(x = 0, 0.025, 0.05, 0.075, 0.1) was prepared using self-ignition sol-gel method. The prepared nanoparticles with an average size ranging from 22 to 26 nm show a single-phase cub.c structure b.longing to the spinel matrix. A rise in the Gd^(3+)concentration leads to an increase in crystallite size and lattice parameter. In Fourier transform infrared spectra, two main ab.orption b.nds b.longing to the spinel structure are ob.erved. The high-frequency b.nds(v_(1)) represent the tetrahedr.l complex, while the lowfrequency b.nds(v_(2)) signify the octahedr.l complex. The optical b.ndgap of the nanoferrites is found within the range of 2.91 to 2.41 eV, depending on their size. The magnetic characteristics of the material,such as saturation magnetization and coercivity are significantly altered with the concentration of Gd^(3+)in the solution. Using Rhodamine b.Rhb. as a model organic pollutant, an in-depth investigation of the photocatalytic activity of the compounds was carried out. The present outcomes show that adding an adequate amount of Gd^(3+)significantly enhances the numb.r of hydr.xyl radicals produced b. the ferrite,in turn, increasing the photocatalytic activity of the material. Mechanism elucidated b. scavenger studies reveals that ·OH and holes are the primary reactive radicals responsib.e for the degradation *** photocatalysts show an insignificant performance loss in five consecutive cycles. Thus, it is concluded that these photocatalysts are highly suitab.e for the remediation of dye-contaminated wastewater.

本研究采用高速火焰喷涂(HVOF)沉积技术,将碳化钒(VC)和铜镍铬(CuNiCr)复合涂层应用于SS316不锈钢上,以解决不锈钢在海洋环境中的腐蚀问题。在室温环境下,在3.5%氯化钠溶液中进行电化学腐蚀,通过扫描电子显微镜(SEM)和能量色散光谱(EDS)对有涂层和未覆涂层样品的表面形貌进行检测。结果表明,涂层内由铜(Cu)、镍(Ni)和铬(Cr)组成的金属间黏合剂在氯化钠介质的影响下发生变质,从而导致出现衬底间的局部点蚀现象。有趣的是,在涂层配方中加入碳化钒(VC)显著地增强了表面的耐腐蚀性能,从而阻止了密闭腐蚀凹坑的出现。在不同类的涂层中,加入VC的效果最好,最小的腐蚀速率为72.38×10^(-3)mm/a,相比之下,SS316基底的腐蚀速率最快。
