Molecular liquids

Two silver salts, silver tetrafluoroborate and silver trifluoromethanesulfonate were dissolved in two different room temperature ionic liquids (RTILs), 1-Butyl-3 methyl imidazolium tetrafluoroborate ([Bmim][BF4]) and 1-Butyl-1 methyl pyrrolidinium trifluoromethanesulfonate ([Bmpy][Tfms]). Triton x-100 (TX-100) surfactant and cyclohexane as nonpolar medium are used to dissolve these RTILs to create reverse micellar system. Pure reverse micellar system is characterized by dynamic light scattering (DLS)

Excess molar volumes, \(V_{123}^{\mathrm{E}}\) , of 1,3-dioxolane or 1,4-dioxane (1) + aniline (2) + benzene or toluene (3) ternary mixtures have been determined over the entire mole fraction range at 308.15 K. \(V_{123}^{\mathrm{E}}\) data have been fitted to the Redlich-Kister equation to evaluate ternary adjustable parameters and standard deviations. The observed \(V_{123}^{\mathrm{E}}\) data have been analyzed in terms of (i) Graph theory, (ii) Prigogine-Flory-Patterson theory, and (iii) Sanchez and Lacombe theory. It has been observed that \(V_{123}^{\mathrm{E}}\) values predicted by Graph theory compare well with the corresponding experimental values.

In the present study, we have synthesized silver nanoparticles (AgNPs) from the extract of P. dactylifera leaves and tested its dose dependent potency against E. coli and K. pneumoniae. The morphological characteristics (size and shape) of our biogenic AgNPs were confirmed by scanning electron microscopy and X-ray diffraction techniques. Growth kinetic studies for E. coli and K. pneumoniae were performed in the presence of various concentrations of AgNPs (0, 8, 16, 32 and 64 μg mL−1). 100% potency for E. coli (3.6 × 107 cfu mL−1) and K. pneumoniae (3.2 × 107 cfu mL−1) was achieved at the end of 3 h where the minimum inhibitory concentration (MIC) against former and latter bacteria was 8 and 16 μg mL−1 respectively. Surface morphological analyses of the deceased bacteria indicate that AgNPs ruptured the cell membrane that led to bacterial death. Hence, our findings confirm that AgNPs developed from P. dactylifera leaves serve as a fast acting potent antibacterial agent. The feasible and cost-effective synthesis would make our developed method as a potential contender in pharmaceutical products and medical devices.
