Corrosion inhibition mechanism of a functionalized schiff base–derived quaternary ammonium salt for carbon steel in 1 M HCl: electrochemical, adsorption, and theoretical studies
Mohamed I. Ahmed, M. Abd-El-Raouf, M. A. Migahed, Magdy A.M. Ibrahim, Sameh A. Rizk, et al.
Scientific Reports, 2026
To address costly corrosion and material degradation, we report the development of a new quaternary ammonium salt (Q-Ar) via functionalization of a Schiff base with benzyl chloride through a quaternization reaction, intended as a potential corrosion inhibitor for carbon steel (C-steel) in 1 M HCl. FT-IR and 1 H NMR spectroscopy confirmed the chemical structure of Q-Ar. Electrochemical potentiodynamic polarization (PDP) studies revealed that Q-Ar acted as mixed-type inhibitor and achieved corrosion inhibition efficiency 93.94% at 35 ppm. Electrochemical impedance spectroscopy (EIS) confirmed strong adsorption layer with charge transfer resistance (R ct ) of 737.3 Ω.cm 2 . The adsorption behavior followed the Langmuir isotherm model, suggesting chemical adsorption reaction of Q-Ar at room temperature over C-steel surface according to standard adsorption energy values (∆G ads ) of -43.2 kJ.mol − 1 for Q-Ar. Activation thermodynamic parameters of C-steel reaction in presence of Q-Ar suggested its inhibition action forming barrier film over C-steel surface as reflected by the increase in activation energy (Eₐ) from 21.60 kJ mol − 1 for the uninhibited system to 42.79 kJ mol − 1 in the presence of Q-Ar. Scanning electron microscopy (SEM) confirmed the protective effect of Q-Ar, showing that the C-steel surface remained largely free of corrosion products compared with the severely corroded blank sample. Energy-dispersive X-ray (EDX) analysis further verified this observation by revealing a marked reduction in iron oxide formation in the presence of Q-Ar. Theoretically, the lower energy gap (ΔE gap ) of the optimized Q-Ar molecule and the higher adsorption energy (E ads ) of the Q-Ar/Fe(110) system indicate strong interactions between the Q-Ar and the C-steel surface, corroborating the experimental observations.

Chemistryselect, 2026
A novel Fe (III) coordination polymer, was synthesized rapidly via a microwave/ultrasonication method utilizing the organic linker O‐HetCur‐CO and characterized using FT‐IR, powder x‐ray diffraction (PXRD), scanning electron microscopy (SEM)/EDX, x‐ray photoelectron spectroscopy (XPS), TGA, and density functional theory (DFT) computations. The linker and polymer were produced with yields of > 70%. The reaction to form the polymer took place in approximately 5 min at 70°C. Structural characterization methods confirm that coordination has occurred between Fe and the linker (stronger than expected). TGA results indicate that the Fe‐(O‐HetCur‐CO) coordination polymer (FeCP) is stable to ∼340°C. EDX data (weight percentages) show that the final polymer composition consists of C (72.50%), N (9.64%), O (12.75%), and Fe (5.11%). DFT calculations show that coordination with Fe significantly alters electronic properties of the linker: Band gap changes from 2.1410 to 3.9002 eV; the dipole moment changes from 5.5337 to 8.4542 D. Thus, the Fe coordination increases the polarity and structural stability of the final polymer. FeCP adsorption studies of 2,4,5‐T showed rapid uptake to equilibrium within 60 min at concentrations ranging from 10 to 50 ppm. The Langmuir isotherm model produced an excellent fit of equilibrium data ( R 2 = 0.9999) with a maximum adsorption capacity of 54.9 mg g − 1 , K L = 0.1689 L mg − 1 and R L = 0.10 indicating a highly favorable monolayer adsorption process; whereas, the Freundlich model yielded K F = 1.175, n = 0.361 and R 2 = 0.9219 revealing that the surface is heterogeneous but with a dominant chemical adsorption phenomenon. Adsorption studies theoretically validated the experimental results in that FeCP/2,4,5‐T adducts displayed a significant reduction in their band gap (1.9100 eV), an increase in dipole moment (11.43 D), and an electrophilicity index (41.2571 eV). All indicative of strong interfacial electron coupling and donor/acceptor interaction. Also of note, FeCP maintained satisfactory adsorption efficiency after five consecutive adsorption cycles, indicating its great promise for herbicide remediation from pollutant‐laden water.

Journal of Heterocyclic Chemistry, 2026
A new series of pyrazoline and pyrazoline–thiazole derivatives conjugated with tetralin ring 5a, b–19 was created starting with the chalcones 3a , b . The new compounds were tested as potential anticancer agents on three human cancer cell lines (HCT‐116, HepG‐2, and MCF‐7) and one human normal cell line (BJ‐1). The Compounds 5a , b , 7a , 9a , b , 10 , 13a , d , and 16b were identified as strong candidates against the MCF‐7 cell line (IC 50 = 2.0 ± 0.1–5.6 ± 0.2 μM), where all the compounds exhibited significant activity against the HCT‐116 cell line (IC 50 = 2.8 ± 0.1–6.5 ± 0.5 μM). Compounds 5b, 9b , and 10 were chosen to study VEGFR‐2 inhibitors in comparison with sorafenib (IC 50 = 2.9 ± 0.08, 8.6 ± 0.41, 1.1 ± 0.04, and 0.2 ± 0.01 nM, respectively). A molecular docking study was conducted to ascertain the latter compounds' binding interactions with VEGFR‐2 kinase.

Multifunctional PES-based nanocomposites: from water treatment membranes to effective radiation shielding materials
Abdelmoniem E. Alahmer, Sameh A. Rizk, Atef S. Darwish, Abdelfatah T. Elgendy, Mohamed E. M. Ali, et al.
Journal of Materials Science Materials in Electronics, 2025
In this study, novel composite membranes based on polyethersulfone (PES) reinforced with nano-copper (N-Cu) particles were developed using the phase inversion method. The primary aim was to enhance water treatment performance, while simultaneously evaluating their potential as lightweight radiation shielding materials, thus providing a dual-functional platform. The prepared membranes were systematically characterized using FTIR, SEM, TEM, EDX, TGA, as well as adsorption tests and contact angle measurements. Results revealed successful and homogeneous dispersion of N-Cu within the PES matrix, leading to significant improvements in surface and hydrophilic properties. The contact angle decreased from 59.7° to 36.5°, confirming enhanced wettability, while the pure water flux (PWF) increased dramatically from 28 LMH for pristine PES to 135 LMH for PES/N-Cu FSM, indicating nearly a fivefold enhancement. Additionally, the PES/N-Cu FSM exhibited superior adsorption capacity toward pollutants (methylene blue), achieving ~ 25% higher removal efficiency compared to pristine PES. Radiation shielding performance was further assessed using Monte Carlo (MCNP) simulations validated by EpiXS software. The results confirmed that PES/N-Cu FSM displayed significantly higher linear attenuation coefficients than pristine PES, with effective shielding against γ-rays and fast neutrons up to 15 MeV. The incorporation of nano-copper increased the effective density and photon interaction probability, thereby improving radiation attenuation while maintaining lightweight characteristics. Overall, PES/N-Cu FSM demonstrates a unique dual functionality by combining efficient water purification with effective radiation shielding. This positions it as a promising candidate for applications in medical, industrial, and environmental fields where both clean water and radiation protection are simultaneously required.

This study focused on the synthesis of six bio-based zwitterionic surfactants derived from oleic acid to assess their applicability in different petroleum fields. The final bi-zwitterionic surfactants were synthesized from oleic acid, utilizing the double bond and carboxylic group. Friedel–Crafts alkylation, sulfonation, chlorination, amidation, and quaternization were performed to synthesize six bi-zwitterionic surfactants. The bi-quaternary surfactants derived from benzene are represented by the general formula Bi Q 10, BOAS (Amide), with the symbols BE, BP, and BPh. In contrast, those derived from naphthalene are represented by Bi Q 10, NOAS (Amide), with the symbols NE, NP, and NPh. The structures of these surfactants were confirmed using FT-IR and H1-NMR techniques. The surface activity and thermodynamic properties of the synthesized surfactants were analyzed through surface tension measurements conducted at various temperatures (30, 40, 50, and 60°C). Additionally, CMC, γ CMC , π CMC , Γ max , A min, and Pc 20 were measured. The thermodynamic variables for micellization and adsorption were also measured. The structural effect of the obtained surfactants was assessed. The maximum value of the structural effect was 4.33 KJmol-1, corresponding to BE. The results indicated that the negative values of ΔGads were greater than the negative values of ΔGmic, indicating that these surfactants are absorbed in the interface prior to the formation of micelles. The more negative values of ΔGads suggest that these surfactants are strongly adsorbed onto solid particles, such as sands and rocks, indicating their potential utilization in oil production in different petroleum fields.
