“…The positions of high intensity peaks refer to the formation of pure Ru/Ag/Pd trimetallic NPs. Peaks appeared at 2θ = 40.11, 46.15, and 68.31 which correspond to (111), (200), and (220), respectively, and are consistent with a conventional Pd-NPs phase pattern [29,30]. Ag NPs showed typical peaks corresponding to the (111), ( 200), (220), and (311) planes at 2θ values of 38.14, 44.35, 65.00, and 77.5, respectively [31].…”

Green synthesis of nanocomposite ruthenium/silver/palladium (Ru/Ag/Pd)-Np was carried out using garlic leaves extract for the reduction of equal quantities of ruthenium nitrate, silver nitrate, and palladium acetate. Some physico-chemical approaches were used to characterize the Nps, including infrared spectra (FT-IR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and scanning electron microscope (SEM). XRD revealed that the crystal size of the nanocomposite was 15.67 nm. After removing all of the precursor's anionic portions, TGA revealed a straight line, confirming the creation of a composite metallic form. Due to metal-metal interactions and the absence of typical bands of acetate and nitrate groups, IR spectra revealed faint multiple bands in the far infrared range. The antimicrobial efficacy of the nanocomposite was examined against Aspergillus flavus, Aspergillu niger, Candida albicans, Candida glabrata, Escherichia coli, and Bacillus cereus. The results showed a potent antimicrobial activity toward all tested microorganisms. UV irradiation greatly improved the antiproliferative efficacy of the nanocomposite against HepG2, Caco2, and K562 cancer cell types. After UV exposure, (Ru/Ag/Pd)-Np also caused Caco2 cells' cell cycle arrest, apoptosis, and necrosis. In conclusion, Ru/Ag/Pd-Np exhibits potent antimicrobial activity and antiproliferative efficacy against different cancer cell lines. The antiproliferative potential of Ru/Ag/Pd-Np was significantly improved following UV irradiation.

Two compounds were prepared: cadmium oxide/cobalt oxide (referred to as oxide A) and silver decorated cadmium oxide/cobalt oxide (referred to as oxide B). Yttrium aluminium garnet (Nd:YAG) lasers, doped with neodymium, were used to irradiate the samples at 532 nm and 1064 nm. The effect of the Nd:YAG laser on the morphological, optical, structural, and antibacterial properties was investigated. The XRD data shows that both oxides are polycrystalline, and the laser irradiation increases the crystal size. Additionally, scanning electron microscopy results (SEM) show that particle size increases with laser irradiation and laser wavelength. While both oxides expand under the influence of a laser, oxide A has a larger optical band gap than oxide B. The intensity of PL increases with the pulsed laser effect and the addition of Ag. The antibacterial test shows that silver is quite effective in eliminating germs and other harmful microbes for human health. Moreover, the results show that, after adjusting the other laser parameters, the wavelength of 1064 nm performed better compared to the wavelength of 532 nm in pure water.

“…The XRD analysis has also been applied to determine the crystallite size of the deposited particles and lattice strain induced. The average crystallite size can be determined by the line broadening technique of XRD using the Debye Scherrer Equation which is given by [21], where D represents nanometric particle size, k represents a constant known as ‘crystallite shape factor’ (0.94), λ represents the wavelength of X-ray radiation (1.5405 Å, CuK α radiation), β represents full width at half maximum of the peak in radians and θ represents Bragg's angle in degrees [22]. The average crystallite size of the deposited particle is calculated as 25.77 nm.…”

Now-a-days carbon nanotube (CNT) is widely used because of its inimitable properties such as high electrical and thermal conductivities, high tensile strength, etc. In this work, an attempt has been made to modify the surface of Al-7075 alloy using Cu-MWCNT powder metallurgy green compact tool in the electric discharge machining process. The effects of contributing parameters i.e. peak current (I p ), voltage and compact load (CL) have been investigated with respect to performance measures such as, Material Deposition Rate (MDR), Tool Wear Rate (TWR) and Surface Roughness (Ra). The modified surface has been assessed by optical microscopy, FESEM, XRD and EDS analyses. Highest MDR of 0.15 mg min -1 , lowest TWR of 2.05 mg min -1 and lowest Ra of 2.57 µm have been attained. The deposition of tool materials has improved the microhardness up to 2.6 times than that of base material.
