Abstract Thin film composite (TFC) polyamide membranes are crucial for efficient reverse osmosis (RO) desalination, offering high selectivity and permeability. This study investigates the fabrication optimization of TFC on polysulfone supports, focusing their structural, morphological, performance properties enhanced desalination efficiency using phase inversion technique, a method that enables precise control over membrane structure. Key parameters including concentrations m-phenylene...
Layered Double Hydroxide (LDH) based on Metal Organic Framework (MOF) structures has attracted a great deal of attention due to their high surface area, tailoring structure the MOF, and pseudocapacitance LDH. Herein, an Ni-ZIF-67/Mn-LDH supercapacitor electrode was prepared via solvothermal method at room temperature. A Ni-ZIF-67/GO-LDH by replacing active metal Mn with graphene oxide (GO) also synthesized enhance capacitance retention stability from 78% 97% after 1000 cycles. The morphology...
Electron paramagnetic resonance (EPR) studies are carried out on composite samples of SmBa2Cu3O7-δ/(MnFe2O4)x superconductors with 0.00 ≤ x 0.20 wt% at different temperatures 100K T 295K. An EPR signal Cu2+ ions in the orthorhombic local symmetry is observed. Moreover, intensity increases as temperature decreases from room down to 100 K. The dependence g-factors indicates pseudogap onset (T*), corresponding peak observed curves between 127 K and 162 number spins (N) participating calculated...
SmBa2Cu3O7-δ /(ZnFe2O4)x superconducting composites with 0.00 ≤ x 0.20 wt% were prepared by the usual solid-state reaction method. The samples investigated using X-ray powder diffraction (XRD) at room temperature and electron paramagnetic resonance (EPR) measurements in range (100-295 K). It is found that EPR spectra are dominated an anisotropic Cu2+ pattern. Moreover, spectral intensity increases as decrease from down to 100 K. number of spins (N) participating resonance, activation energy...
Perovskite solar cells (PSCs) represent one of the most models organic-inorganic which have achieved a great success in last years.However, there are some challenges facing this such barrier between layers' interfaces and presence grains that impedes passage charge carriers.Consequently, aim work is to synthesize characterize passivated peroviskte layers using different passivation techniques for producing treated perovskite cells.These were characterized by scanning electron microscope...
