Impact of ablation time on Cu oxide nanoparticle green synthesis via pulsed laser ablation in liquid media

Abstract: Large-scale commercial production of nanoparticles via efficient, economical, and environmentally friendly methods is a challenging endeavour. The laser ablation method being a green and potential route of nanoparticles synthesis can be exploited to achieve this end. In this work, we report the ablation of a copper target submerged in distilled water by pulsed Nd:YAG laser. The influence of ablation time on the structure and optical properties of grown copper oxide nanoparticles are studied. Such nanoparticle composition and structure is determined by X-ray diffraction (XRD), Fourier transform infrared, and Raman analyses. Results from transmission electron microscopy images established that synthesised nanoparticles are a spherical shape with average sizes of 24–37 nm. Fluorescence spectra revealed the enhancement of nanoparticle concentration and reduction in the sizes with increasing ablation time, where the optimum ablation time is demonstrated to be 60 min. Photoluminescence spectra exhibited a prominent visible peak (green), which blueshifted from 542 to 537 nm, confirming the shrinkage of copper oxide particle size at higher ablation time. The XRD pattern showed that the prepared nanoparticles possess a single phase of monocline cupric oxide nanostructure.

Molecular Epidemiology of Bovine Papillomatosis and Identification of Three Genotypes in Central Iraq.

Abstract: Objective: This study aims to provide a molecular and epidemiological characterization of bovine papillomavirus (BPV) infections in Iraq. Methods: The present study focuses on identifying BPV based on clinical and epidemiological manifestations, histopathological examinations, and polymerase chain reactions (PCR). Samples were collected from 163 animals suffering from cutaneous bovine papillomatosis, including 129 females (79.14%) with an age range of 16–40 months and 34 males (20.85%) with an age range of 17–29 months. Results: The incidence rate was significantly higher in females than in males. The most commonly affected sites were the teats and neck, though warts were found in other areas of the body. Histological sections were diagnosed as fibropapilloma. PCR results showed that 80.13% of the extracted papilloma DNA samples corresponded to the BPV-1 genotype. Furthermore, 7.94% of the samples showed a mixed infection of BPV-1 and BPV-13. While, 40.63% of the extracted DNA blood samples showed 2 DNA fragments corresponding to both genotypes BPV-1 and BPV-2. Conclusions: This study confirmed the presence of BPV-1, BPV-2, and BPV-13, which belong to the Deltapapillomavirus genera, for the first time in the DNA of Iraqi cattle. Understanding BPV diversity and epidemiology is of critical importance for starting prevention strategies.

Magnetic dipole moments, electric quadrupole moments, and electron scattering form factors of neutron-rich s d -p f cross-shell nuclei

Abstract: Magnetic dipole and electric quadrupole moments are calculated for neutron-rich sd-pf cross-shell nuclei. These nuclei include open shell isotopes with the number of protons less than 20 and neutrons greater than 20, for which experimental data are available. Shell model calculations are performed with full $sd$ shell model space for $Z$\ensuremath{-}8 valence protons and full $pf$ shell model space for $N$\ensuremath{-}20 valence neutrons, where the remaining 20 neutrons are frozen in $s$, $p$ and $sd$-shells. Also, magnetic and Coulomb electron scattering form factors are calculated for some of these nuclei. Excitation out of major shell space are taken into account through a microscopic theory which allows particle-hole excitation from the core and model space orbits to all higher orbits with $2\ensuremath{\hbar}\ensuremath{\omega}$ excitation. Effective charges are obtained for each isotope. Core polarization (CP) is essential for obtaining a reasonable description of the electric quadrupole moments and enhance the Coulomb form factors but has no effect on the dipole magnetic moments but squeezes the magnetic form factors. The magnetic static and dynamic properties can be described by free $g$ factors for the model space nucleons without introducing CP effect, on the contrary to the electric static and dynamic properties, which cannot be described properly by the model space nucleons without taking into account CP effects.
