Commercial antifungal drugs lead to develop fungal resistance and cause their
own side effects to humans. Alternative use of plant essential oil as antifungal
agent was attempted. The present study revealed that the extracted essential
oil from Artemisia nilagirica was assessed for its chemical constituents and
antifungal activity against four food borne fungi. Forty compounds were present
in the essential oil out of which thujone was the major compound followed by
γ- curcimene, α- caryophyllene, lavundulol and germacrene. Minimum inhibitory
concentration for Aspergillus flavus, Aspergillus niger, Fusarium oxysporum and
Penicillium notatum was 57.33, 32.66, 87.66 and 13.66 µl/L air respectively.
Results obtained showed that the Essential oil has more potency against P.
notatum followed by other fungal species at a slightly higher concentration localization and exciton generation rate distribution happened to be available in such nanostructures and influence in exciton generation in perovskite absorbing materials deposited atop in tandem configuration. Figure as shown below depicts the evidence of Si-NPys of Si-NWs growth using Si wafer as initial materials. It is noteworthy to mention that the dimension of such silicon nanostructures depends on experimental conditions such as temperature, precursor concentration, etching time etc.FDTD simulation suggested confined exciton generation rate distribution in such nanometric structures and thus active absorbing material such as perovskite would get enormous influence thereof.Authors acknowledge CoRERE, RI, KFUPM, Dhahran 31261, Saudi Arabia.
