Opto-Mechanical Characterization and Antimicrobial Performance of iPP/TiO2 and iPP/Ag Nanocomposite Fibers: A Combined Stokes Polarimetry and Birefringence Analysis Moayad M. Khashoqji, Thamer S. Alraddadi, Alaa M. Munshi, Mohammed D. Sharahili, Hawra A. Alghasham, Maer Alanazi, Nahla Albarakati, Nashwa M. El‐Metwaly Luminescence, 2026 This study investigates the opto‐mechanical properties and antimicrobial performance of isotactic polypropylene (iPP) nanocomposite fibers reinforced with TiO 2 and Ag nanoparticles at 2.5 wt% loading. A modified Mach–Zehnder interferometer integrated with Stokes polarimetry was developed for direct birefringence quantification using S 2 and S 3 parameters, with three‐dimensional optical anisotropy profiles reconstructed via inverse Abel transform. Antimicrobial evaluation against four clinically relevant pathogens demonstrated superior performance for iPP/Ag nanocomposites (78.4 ± 8.4% growth inhibition) compared to iPP/TiO 2 systems (66.8 ± 7.3%). Birefringence analysis revealed significant enhancement upon nanoparticle incorporation, with iPP/TiO 2 fibers showing 39% higher birefringence (0.0146) compared to pristine iPP (0.0105), whereas iPP/Ag systems exhibited 26% enhancement (0.0132). Progressive mechanical drawing demonstrated that iPP/TiO 2 nanocomposites achieved superior drawability (maximum draw ratio 4.2) with exceptional birefringence development (0.0459), surpassing iPP/Ag systems (draw ratio 3.9, birefringence 0.0394) and pristine iPP fibers (draw ratio 3.4, birefringence 0.0312). These findings establish comprehensive structure–property relationships for advanced nanocomposite fiber systems with tailored multifunctional properties.
Dye removal by the designed carbon nanostructures@TiO2: infrared-assisted synthesis and methylene blue degradation Yasmeen A. S. Hameed, Alaa M. Munshi, Marwah A. Alsharif, Abdulrhman M. Alsharari, Rami Pashameah, Deemah M. Alenazy, Nada Alkhathami, Nashwa M. El-Metwaly Applied Water Science, 2025 Titanium dioxide (TiO 2 ) is applicable in photocatalysis and light-induced processes for activation of substrates, to be superiorly applicable for converting toxic containments into harmless fragments. Carbon nanostructures (CNs) are extensively attracted the attention of researchers, attributing to their diversity and exclusive physicochemical characters. Herein, the affinity of CNs either under acidic or basic conditions is studied for enhancing the catalytic potency of TiO 2 in order to be applicable without light, that is considered to be more economic, energy and cost-saving purposes. Currently, carboxymethyl starch was exploited as an origin for CNs under the infrared-assisted conditions. Afterward, CNs were successfully uploaded within TiO 2 under both acidic (CNs@TiO 2 -formic) and basic (CNs@TiO 2 -NaOH), to be applicable for catalytic degradation of methylene blue. CNs-formic were successfully prepared with slight smaller average size (6.6 ± 1.9 nm) rather than the base-CNs-NaOH (9.8 ± 3.7 nm). CNs@TiO 2 -formic were exhibited with higher catalytic performance rather than CNs@TiO 2 -NaOH. MB degradation percent reaches 98% after only 30 min by exploiting CNs@TiO 2 -formic as a catalyst in the absence of light. Moreover, without irradiation, t 1/2 was superiorly shortened by nearly ten times under the catalytic performance of CNs@TiO 2 -formic in the absence of light.
Facile Synthesis and Characterization of Novel Fe0.65Mg0.35Cr2O4@C Nanocomposite for Efficient Removal of Cd(II) Ions from Aqueous Media Ehab A. Abdelrahman, Reem K. Shah, Mortaga M. Abou-Krisha, Fawaz A. Saad, Alaa M. Munshi Inorganics, 2025 Cd(II) ions pose significant environmental and health threats due to their extreme toxicity, persistence, and bioaccumulation in ecosystems. They are associated with severe health disorders such as bone damage, kidney failure, and carcinogenic effects and disrupt aquatic life by impairing enzymatic and reproductive processes. In this research, novel Fe0.65Mg0.35Cr2O4@C nanocomposites, synthesized using the Pechini sol–gel method at 600 °C (F600) and 800 °C (F800), were investigated for their efficacy in removing Cd(II) ions from aqueous media. FE-SEM analysis showed that F600 had agglomerated spherical nanoparticles with an average grain size of 45.71 nm and a relatively porous structure, while F800 displayed denser and more compact spherical nanoparticles with an average grain size of 73.65 nm. HR-TEM images confirmed these findings, showing that F600 nanoparticles were loosely arranged with an average particle diameter of 14.72 nm, whereas F800 exhibited larger, more aggregated particles with an average diameter of 59.22 nm, reflecting enhanced particle coalescence at higher temperatures. EDX analysis confirmed the elemental composition of both samples, with F600 containing higher carbon content (7.0%) compared to F800 (3.4%), attributed to the more complete combustion of organic precursors during F800’s synthesis. This difference in composition, along with the structural variations, influenced their adsorption performance. F600 demonstrated superior adsorption with a maximum capacity of 295.86 mg/g compared to F800’s 185.19 mg/g. Thermodynamic and kinetic analyses confirmed that the adsorption was exothermic, spontaneous, and governed by a physical mechanism following the pseudo-second-order model and Langmuir isotherm. The superior performance of F600 is attributed to its higher surface area, porosity, and smaller particle size, which enhance the availability of active adsorption sites.
Modification of nickel ferrite nanoparticles by sodium docusate surfactant for superior crystal violet dye removal from aqueous solutions Nada S. Al-Kadhi, Ghadah M. Al-Senani, Fawaz A. Saad, Alaa M. Munshi, Ehab A. Abdelrahman Scientific Reports, 2024 In this study, nickel ferrite (NiFe 2 O 4 ) nanoparticles were synthesized using the Pechini sol-gel method and modified with sodium docusate surfactant. The modified nanoparticles showed an enhanced adsorption capacity of 384.62 mg/g for crystal violet dye, compared to 237.53 mg/g for unmodified NiFe 2 O 4 . Characterization was performed using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM) techniques. The adsorption process was spontaneous, exothermic, and followed the Langmuir isotherm and pseudo-second-order kinetic model. Optimal conditions for maximum dye removal were achieved at pH 10, 50 min, and 298 K. Additionally, the synthesized adsorbents demonstrated excellent regeneration and reusability over five adsorption-desorption cycles with minimal efficiency loss.
Efficient removal of crystal violet and acid red 88 dyes from aqueous environments using easily synthesized copper ferrite nanoparticles Asma S. Al-Wasidi, Ehab A. Abdelrahman, Khalil ur Rehman, Fawaz A. Saad, Alaa M. Munshi Scientific Reports, 2024 ) nanoparticles for the efficient removal of acid red 88 and crystal violet dyes from aqueous solutions. Utilizing a combustion method, nanoparticles were synthesized with succinic and malic acids as fuels, yielding samples with crystallite sizes of 28.54 ± 0.90 nm for the sample synthesized with malic acid and 19.79 ± 0.75 nm for the sample synthesized with succinic acid. Optimum removal conditions were found at a pH of 2 for acid red 88 and pH 10 for crystal violet, with a contact time of 80 min and an adsorbent dosage of 0.05 g in a 100 mL solution. Under these conditions, the sample synthesized using succinic acid achieved sorptive capacities of 452.49 mg/g for acid red 88 and 446.43 mg/g for crystal violet, while the sample synthesized using malic acid reached 408.16 mg/g and 374.53 mg/g, respectively. Both adsorption processes followed the pseudo-second-order kinetic model and aligned with the Langmuir isotherm. Thermodynamic analysis confirmed the process as exothermic and spontaneous. Practical trials demonstrated removal efficiencies above 95% for both dyes in real wastewater samples, underscoring the method's practical potential in water purification applications.
Adsorbent beads based on Fe-BTC@Chitosan/microcrystalline cellulose for simultaneous removal of sulfa drugs Kaseb D. Alanazi, Basmah H. Alshammari, Fatmah M. Alkhatib, Kholood M. Alkhamis, Alaa M. Munshi, Amal H. Al-Bagawi, Amal H. Alsehli, Nashwa M. El-Metwaly Cellulose, 2024 Sulfa drugs are mostly used as antimicrobial regents for treatment of several infections. Sulfa drugs can easily be accumulated in the human cells and can be leached out to cause water pollution. Nowadays, the removal of sulfa drugs from polluted wastewater is of research interest. According to our knowledge, application of bead-based biopolymers and metal organic framework (MOF) in the removal of sulfa drugs has not been investigated. The novelty in the current approach is to exploit a composite of chitosan and MOF for removal of sulfa drugs. The approach synthesizes a composite bead that is based on Fe-benzenetricarboxylic acid (Fe-BTC) a superiorly applicable MOF, and the biopolymers chitosan (Chs) and microcrystalline cellulose (MCC) for removal of sulfa drugs. The present study interests in the efficient removal of two kinds of sulfa drugs (sulphanilamide and sulfamethazine) by using the currently prepared bead. Chitosan (Chs) and microcrystalline cellulose (MCC) were used as sources for the bead. The materials interacted together to obtain Fe-BTC@Chs/MCC bead. Fe-BTC was well-distributed over the networked structure of Chs/MCC and filled the pore structure. Adsorption of sulfa drugs onto the synthesized beads was well-fitted to the pseudo-second order and isothermally to Langmuir. The affinity of Fe-BTC@Chs/MCC bead toward sulfamethazine was notably higher than that of sulphanilamide. Adsorption capacity of sulfa drugs onto Fe-BTC@Chs/MCC bead was decreased by only 16.4–15.5% after five reuse cycles which declare the substantial stability during the regeneration process.
