“…The hydrodynamic sizes of metallomicelles as estimated using DLS were 150 nm in ethanol, 160 nm in propanol, and 168 nm in butanol. The size was found to increase with increase in the hydrophobicity of alcohols . The particle size analyses data are given in Supporting Information as Figure S3.…”

“…Micelles as templates were chosen for simplicity; however, because complex 1 have limited aqueous solubility and to understand the formation of metallomicelles of complex 1 , alcohols were selected as medium . A similar attempt with solvophobic palladium dodecylammonium acetate complex had been made earlier, where metallomicelles were studied in n -alcohols. Keeping this in view, the micellization behavior of complex 1 in ethanol, propanol, and butanol was investigated.…”

“…Five different nonisothermal methods, 43 namely, those of Horowitz−Metzger, Coats−Redfern, Madhusudanan− Krishnan−Ninan, Wanjun−Yuwen−Hen−Cunxin, and Van Krevelen, were employed to determine the activation energy for the first decomposition step of complex 1 (Table 4) by plotting linearization curves. The details of equations are as follows:…”

A one-pot synthesis of solvophobic bisdodecylaminepalladium(II) chloride (complex 1) was performed. Complex 1 was characterized using X-ray crystallography and other techniques, namely, mass spectrometry, Fourier transform infrared, NMR, elemental analysis, etc. A multifaceted approach was taken to explore the potential applications of complex 1. The micellization ability of complex 1 was estimated using conductivity method in n-alcohols. The metallomicelles are formed in alcohols, and the process is thermodynamically spontaneous in nature. Using complex 1 as precursor, palladium (Pd) nanoparticles were fabricated using two-phase redox method, where reduction is being performed in core of metallomicelles formed by complex 1 in dichloromethane (DCM). The micellization in DCM is confirmed by small-angle X-ray scattering (SAXS). The SAXS measurements reveal that the micellar of core 4-5 nm is being formed, which further controls the size of nanoparticle. This approach was advantageous in terms of size control, methodology, and yield. Pd nanoparticles were characterized using transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and UV-visible spectroscopy and were also screened for bovine serum albumin interactions. Complex 1 and Pd nanoparticles were found to possess antimicrobial property with broad spectrum and are active against bacteria and fungi. The cytotoxicity analyses were performed over healthy cells (Vero cell lines extracted from kidney of green monkey), and the results reveal IC50 value of 10 μg/mL for complex 1.

“…The best method for the two decomposition phases (i.e., CPyC decomposition and MoO 3 decomposition) was identified using least-squares linear regression (Figure 5). Various kinetic parameters 31,32 of thermal decomposition such as the frequency factor (A), enthalpy (H), Gibbs free energy (G), and entropy (S) are also calculated and tabulated in Table S2 (see the Supporting Information).…”

Cetyl pyridinium chloride (CPyC)-capped stabilized stable spherical molybdenum trioxide nanoparticles (MoO 3 NPs) were synthesized and explored for the degradation of the Eriochrome Black T dye and toxicity profiling via the seed germination assay. The results were supported with exhaustive analytical techniques such as diffuse reflectance spectroscopy, Fourier transform infrared spectroscopy, and dynamic light scattering along with zeta potential, X-ray diffraction, and thermogravimetric analysis. The results from electron microscopic techniques, i.e., transmission electron microscopy and scanning electron microscopy, corroborated the formation of sphericalshaped NPs of ∼10 nm. The NPs illustrate a high electrostatic interaction with the dye molecules and demonstrate good dye removal efficiency (96% in 10 min) because of their higher surface area. The active species (•OH > h + > •O 2 − ) play a prominent role in photocatalytic degradation of dye molecules by NPs. They were also found to assist seed germination as compared to pure Mo. Further, the cytotoxic properties of NPs were also analyzed on the cervical cancer cell line, i.e., HeLa cells. The NPs showed good anti-cancerous activity with an IC 50 value of 12.79 μg/mL, incorporating the synergistic activity of CPyC and MoO 3 .
