This study aimed to investigate the effect of Gadolinium oxide (Gd2O3) concentration (0.5%, 1%, and 2%) on performance polysulfone (PSF) membrane. The membranes were fabricated by a common phase inversion method. was determined based pure water flux, bovine serum albumin (BSA) permeation test. These characterized FTIR contact angle measurements. highest BSA rejection 53%. optimum membrane (2 % ...
In this work, the structural properties and spectroscopic behavior 80 mol.%TeO2-20mol.%LiF glasses which were doped with 0. 05, 0. 2 mole% Gd2O3 have been studied. It was shown that, by increasing the amount of Gd2O3 the glass stability was decreased. The PL emissions at 431nm and 627nm wavelengths were distinguished by 320nm excitation. The FT-IR analysis showed deformed TeO4 groups in these ...
Eu3+doped Gd2O3 nanophosphor were successfully obtained by a straightforward combustion method. The crystal structure and optical characteristics investigated methods: XRD, photoluminescence spectra (PL). XRD result indicates the Gd2O3:5%Eu had cubic phase average particle size was about 32 nm. showed strong red emission with 5D0-7F2 electric dipole transition dominant. intensities of 5D0-7FJ t...
The long-time temperature drift in a commercial Quantum Design MPMS SQUID magnetometer was evaluated using time-dependent magnetization measurements of Gd2O3. In contrast to earlier claims, the amplitude of the drift was found not to exceed 1-1.5 K. 30 minutes after system stabilization the temperature deviation did not exceed 0.2 K and the temperature was fully stabilized in less than 3 hours.

The mononuclear Gd(III) complex, [Gd(L)3(H2O)5] (where L is alizarin yellow R (NaC13H8N3O5)), has been prepared in H2O under reflux condition. The Gd(III) complex has been characterized by elemental analysis and spectroscopic methods (UV–Vis and FT–IR). The Gd2O3 nanoparticles were prepared by the calcination of the Gd(III) complex in air at different temperatures up to 600 °C for 2 h. The calc...
In this paper, two dielectric layers of Al2O3 and Gd2O3 were prepared by an atomic layer deposition (ALD) magnetron sputtering (SD), respectively. Based on this, a metal-oxide-semiconductor field-effect transistor (MOSFET) was successfully hydrogen-terminated single-crystal diamond (H-diamond), its related properties studied. The results showed that device had typical p-type channel MOSFET outp...
An extremely low frequency alternating magnetic field (ELF-AMF) was demonstrated to be able to effectively trigger drug release from carefully engineered magnetic ZIF-90 nanoparticles. The embedded Fe3O4 nanoparticles or alternatively Gd2O3 nanoparticles serve as effective MRI tracers for potential visualization of drug delivery to ensure drug delivery accuracy.
Gd2O3 nanoparticles were synthesized for the first time by sol-gel combustion method and YBCO high temperature superconductor by sol-gel method. X-ray powder diffraction pattern of the nanoparticles and prepared superconductor showed single phase by both methods. The average size of Gd2O3 nanoparticles, according to the Scherrer formula, computed 29 nm, which is consistent with the results obta...
Due to the higher hydrogen solubility and diffusivity, gadolinium sesquioxide (Gd2O3) could be expected as a proton conductive material. In this study, monoclinic Gd2O3 was used evaluate possible conductivity in Ar (?Ar), Ar+4% H2 (?H2), D2 (?D2), Ar+H2O (?H2O), Ar+D2O (?D2O), O2 (?O2) atmospheres temperature range from 500°C 1000°C, understand its application DT fuel system of nuclear fusion r...
