During this study, we report the green synthesis of  magnetic copper ferrite nanoparticles using tragacanth gum as a reducing and stabilizing agent by the sol-gel method. The green synthesized CuFe2O4 MNPs are characterized by powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy...

The tertiary structural changes occurring during the photocycle of bacteriorhodopsin (BR) are assigned by X-ray diffraction to distinct M states, M1 and M2. Purple membranes (PM) of the mutant Asp96Asn at 15, 57, 75 and 100% relative humidity (r.h.) were studied in a parallel X-ray diffraction and Fourier transform infrared (FTIR) spectroscopic investigation. Light-dependent conformational chan...

Depth sensitivities: Research into the initial stages of hydrogenation in a material necessitates the use of a variety of methods that provide the capabilities for characterization of structure and bonding with distinct depth sensitivities. This study makes extensive use of Fourier Transform Infrared (FTIR) spectroscopy, x-ray diffraction (XRD), x-ray absorption spectroscopy (XAS), and soft x-r...

In this study, we have reported the green synthesis magnesium ferrite using tragacanth gel by the sol-gel method without using any organic chemicals. The sample was characterized by powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy (SEM). The X-ray powder diffraction (XRD) analysis revealed the fo...

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...
