Abstract: Bismuth oxide (Bi2O3) is known for its application in several industries such as solid oxide fuel cells, optoelectronics, gas sensors and optical coatings. The present study was designed to evaluate the effect of biofield energy treatment on the atomic, physical, and thermal properties of Bi2O3. The Bi2O3 powder was equally divided into two parts: control and treated. The treated part was subjected to biofield energy treatment. After that, both control and treated samples were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, and electron spin resonance (ESR) spectroscopy. The XRD data exhibited that the biofield treatment has altered the lattice parameter (-0.19%), unit cell volume (-0.58%), density (0.59%), and molecular weight (-0.57%) of the treated sample as compared to the control. The crystallite size was significantly increased by 25% in treated sample as compared to the control. Furthermore, TGA analysis showed that control and treated samples were thermally stable upto tested temperature of 831°C. Besides, the FT-IR analysis did not show any significant change in absorption wavenumber in the treated sample as compared to the control. The ESR study revealed that g-factor was increased by 13.86% in the treated sample as compared to the control. Thus, above data suggested that biofield energy treatment has altered the atomic and physical properties of Bi2O3. Therefore, the biofield treated Bi2O3 could be more useful in solid oxide fuel cell industries.

Abstract: This study aims at investigating the influence of gas atmospheres on the dewetting properties of DC sputtered and rapid thermally annealed silver (Ag) nanofilms. The annealing temperature ranged from 400℃ to 600℃ and the gases studied were argon (Ar) and nitrogen (N2). Scanning electron microscope (SEM) and focused ion beam (FIB) were employed for morphological studies, while the X-ray diffraction (XRD) technique was applied in the structural analysis of the films. The SEM and top-view FIB-SEM images of Ag films annealed in both atmospheres were characterized by irregular shaped holes. At fixed temperature, the films annealed in the N2 atmospheres gave higher hole density and larger hole sizes than the film annealed in the Ar atmosphere. Additionally, the hole density decreased with the annealing time. For films annealed in the N2 atmosphere, isolated dewetted particles were only obtained at 600℃ substrate temperature. The XRD patterns of all the films were characterized by Ag metallic peaks. No significant difference was observed among the films’ crystal structures. The annealing atmospheres mainly influences the morphologies of Ag nanofilms.

Abstract: Nano-sized silver particles (AgNPs) were synthesized by easy and quite simple method, using pectin as both reducing and stabilizing agent. Solutions of AgNPs were applied to cotton fabrics in presence/absence of binder. The finished fabrics were examined for morphological and topographical features by using scanning electron microscopy which reveals that AgNPs- pectin composite are deposited on the surface of coated fabrics. Also, color coordinates were measured for the uncoated and coated fabrics to show the effect of nanosilver loading on the color of coated fabrics. The antibacterial activity of the treated fabrics loaded with AgNPs was evaluated against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus.
