“…36-1451 [34]. Very similar values have also been reported by Arefi and Saeed [35], Dutta and Bichitra [36] and Prabhu et al [34]. A peak at 60°was observed at both wavelengths; this might be due to the glass substrate.…”

Picosecond laser generation of nanoparticles was only recently reported. The effect of laser wavelength in picosecond laser generation of nanoparticles is not yet fully understood. This investigation reports the new findings comparing the characteristics of Au, Ag, Ag-TiO 2 , TiO 2 , ZnO and iron oxide nanoparticles generated by picosecond laser ablation in deionised water at 532 and 1064 nm laser wavelengths. The laser ablation was carried out at a fixed pulse width of 10 ps, a repetition rate of 400 kHz and a scan speed of 250 mm/s. The nanoparticles were characterised by UV-Vis optical spectroscopy, transmission electron microscopy (TEM) and X-ray diffraction (XRD). The work shows that there is no noticeable difference in the size of the metal oxide nanoparticles produced at 532 and 1064 nm, especially for the TiO 2 and ZnO nanoparticles; however, a considerable size difference can be seen for metallic (e.g. Au) and metallic compound (e.g. Ag-TiO 2 ) nanoparticles at the two wavelengths. It demonstrates that noble metals are more profoundly affected by laser wavelengths. The reasons behind these results are discussed. In addition, the work shows that there are different crystalline structures of the TiO 2 nanoparticles at 1064 and 532 nm wavelengths.

“…The absorption band of control and treated sample of ZnO was observed at 440/cm and 425/ cm, respectively. The treated ZnO sample showed lower wavenumber (425/cm), that may be due to unit cell distortion or change in Zn-O bond length [44].

Transition metal oxides (TMOs) have been known for their extraordinary electrical and magnetic properties. In the present study, some transition metal oxides (Zinc oxide, iron oxide and copper oxide) which are widely used in the fabrication of electronic devices were selected and subjected to biofield treatment. The atomic and crystal structures of TMOs were carefully studied by Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD) studies. XRD analysis reveals that biofield treatment significantly changed the lattice strain in unit cells, crystallite sizes and densities in ceramics oxide powders. The computed molecular weight of the treated samples exhibited significant variation. FT-IR spectra indicated that biofield treatment has altered the metal-oxygen bond strength. Since biofield treatment significantly altered the crystallite size, lattice strain and bond strength, we postulate that electrical and magnetic properties in TMOs (transition metal oxides) can be modulated by biofield treatment.

Bioinspired synthesis of nanoparticles is a way to synthesize nanoparticles by using biological sources. It's gaining importance due to its ecofriendly, cost effective and large scale production properties. In this present study, the plant Ficus carica was taken to study its ability for synthesizing zinc oxide nanoparticle. The leaf extract of antimicrobial susceptibility showed that most of the antibiotics were resistant towards bacterial isolates of zinc sulphate hepta hydrate and sodium hydroxide, were used to synthesize the zinc oxide nanoparticles and were confirmed by their change of color to yellowish white due to the phenomenon of reduction. The characterization studies were done by UV-vis spectroscopy, Scanning electron microscopy (SEM), Energy dispersive Analysis of X-rays (EDAX), X-Ray diffraction (XRD), and Fourier Transmission infrared spectroscopy (FTIR). It was confirmed from the XRD pattern that the structure of ZnO nanoparticles (NPs) is crystalline and the average crystalline size of ZnO NPs is 66 nm. The morphology of the nanoparticle was confirmed through SEM and EDAX analysis which shows the hexagonal shape of zinc oxide nanoparticles respectively. FTIR analysis proved that the particle is of biological origin and identified that phenols played a role as a reducing agent. For antibacterial activities, selected antibiotics were impregnated with Zinc oxide nanoparticles synthesized from Ficus carica which showed good activities against Staphylococcus
