The Interdisciplinary Research Center for Membranes and Water Security (IRC-MWS), in collaboration with the Central Research Facilities (CRF) at KFUPM, provides access to state-of-the-art characterization tools that support advanced research in membrane science, nanomaterials, and water treatment technologies. Our facilities include a wide range of microscopy platforms such as scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS) for morphology and elemental analysis, transmission electron microscopy (TEM) for high-resolution structural imaging, and atomic force microscopy (AFM) for surface topography and roughness measurements. Spectroscopic and compositional analyses are supported by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and UV–Vis spectroscopy. Crystallographic and structural insights are provided through X-ray diffraction (XRD), while thermal and stability assessments are enabled by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA). In addition, the center leverages facilities for surface charge and wettability measurements (zeta potential and contact angle analysis), porosity and surface area evaluation (BET analysis), and water quality and performance testing using advanced filtration and separation platforms. This comprehensive suite of tools ensures that IRC-MWS researchers and collaborators can conduct cutting-edge studies from nanoscale material development to pilot-scale water treatment applications.
