“…The desorption or/ degradation of the inhibitor layer at elevated temperature appeared to be the main contributing factor behind this observation, causing increased exposure of the metal surface to the acidic corrosive solution. A decrease in η % with the increase in temperature for all synthesized CDs suggested some physical adsorptions and the weak Vander Waals forces responsible for such type of interaction tended to disappear at elevated temperatures [70]. However, the high-density chemical adsorption processes was predominant.…”

N-CDs, as a novel and eco-friendly inhibitor, were synthesized easily by hydrothermal carbonization technique aiming to inhibit mild steel corrosion in 1 mol. L − 1 HCl. XRD, TEM, SEM, FTIR, UV-vis spectrophotometer and photoluminescence (PL) were utilized to characterize N-CDs. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques along with the complementary surface studies were combined to investigate the corrosion inhibition capability of N-CDs for MS. N-CDs were found nanometer-sized (≈ 4 nm) with quasi-spherical morphology and high crystallinity. Inhibition e ciency, directly proportional to concentration but inversely with temperature, was measured as high as 96.73% (PDP) and 95.21% (EIS) at 200 mg. L − 1 . Inhibition mechanism refered mainly to adsorption process that good obeyed Langmuir adsorption isotherm. The surface studies, quantitatively veri ed by EDX, showed a smoother surface of MS in presence of the N-CDs. Furthermore, the UV-visible spectroscopy effectively revealed the complexations between iron and metal surfaces. IntroductionRecently, designing materials at nanoscale has acquired fundamental applications in many elds starting from everyday life to space innovation. Materials at the nanoscale have extraordinary physical, chemical, electrochemical, mechanical, thermal and biological properties due to their nanoscale size, surface and quantum impacts, that allow to manufacture stronger, harder, biocompatible, and highly corrosion-resistant materials with a wide range of applications in biomedicine, diagnosis, electronics, agriculture, food, pharmaceuticals, energy harvesting for self-powered nano systems, chip fabrication, batteries, fuel cells, corrosion protection of materials, aerospace materials, cosmetics, etc. [1] Among nanomaterials are carbon dots (C-Dots) which plays an important role in nanoscience and nanotechnology since its discovery in 2004 due to their exceptional properties like high uorescencence, water solubility and biocompatibility, low toxicity, and extra small sizes in the range 1-10 nm [2-4]. The subsequent extensive studies gradually revealed the potential applications of C-Dots including anti-counterfeiting [5], optoelectronics [6], uorescence imaging both in vitro & in vivo [7-9], solar cells [10], nanosensing both in vitro & in vivo [8, 11-13], light-emitting devices [14], photocatalysis [11], drug delivery [15], diagnosis of diseases [16], etc. Since 2017, the carbonization of either synthetic and natural organic compounds give rise to the carbon nanodots that revolutionized the eld of metals corrosion inhibition [17-21]. Next work deals with synthesis of C-Dots by the traditional, eco-friendly hydrothermal carbonization method. The properties exhibited by C-Dots depend on the C-sources and conditions used in the synthesis.Most industrial equipment like engineering vehicles, reaction vessels and packaging machineries made from metallic products are inclined to corrosion. One of the most e cient ways of relieving corrosion process is usin...

“…It constitutes an important class of heterocyclic compounds which, even when part of a complex molecule, possess a wide spectrum of biological activities (Rharmili et al, 2023b), such as anticancer (Esmaeelian et al, 2013), antioxidant (Andreani et al, 2010), antimalarial (Chiyanzu et al, 2005), anti-inflammatory (Sharma et al, 2016), analgesic (Prakash et al, 2012) and antianxiety (Medvedev et al, 2005). They have also been studied and been reported as efficient inhibitors against aluminium and steel corrosion (Abdellaoui et al, 2021). In a continuation of our ongoing research work devoted to the study of Oalkylation and N-alkylation reactions involving isatin derivatives (Rharmili et al, 2023b), we report herein the synthesis and the molecular and crystal structures of 1-(4-methylbenzyl) indoline-2,3-dione (Scheme 1) obtained by an alkylation reaction of 1H-indoline-2,3-dione using an excess of 4methylbenzyl bromide as an alkylating reagent and potassium carbonate in the presence of tetra-n-butylammonium bromide as catalyst in phase-transfer catalysis (PTC).…”

The indoline portion of the title molecule, C16H13NO2, is planar. In the crystal, a layer structure is generated by C—H...O hydrogen bonds and C—H...π(ring), π-stacking and C=O...π(ring) interactions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (43.0%), H...C/C...H (25.0%) and H...O/O...H (22.8%) interactions. Hydrogen bonding and van der Waals interactions are the dominant interactions in the crystal packing. The volume of the crystal voids and the percentage of free space were calculated to be 120.52 Å3 and 9.64%, respectively, showing that there is no large cavity in the crystal packing. Evaluation of the electrostatic, dispersion and total energy frameworks indicate that the stabilization is dominated by the dispersion energy contributions in the title compound. Moreover, the DFT-optimized structure at the B3LYP/6-311G(d,p) level is compared with the experimentally determined molecular structure in the solid state.

“…In the presence of water molecules, the DFT approach was used at B3LYP with the 6-311G/(d,p) basis set and the Gaussian 09 program [20].

This article is part of the contribution to the development of two medicinal plants widely used by the Moroccan population: white wormwood (Artemisia herba-alba) andArâr (Juniperus phoenicea), species belonging to the Asteraceae and Cupressaceae families, respectively. The present work was conducted to investigate the chemical composition and anticorrosive properties of essential oils (EOs) extracted from these plants. The chemical analysis of the essential oils (EOs) was carried out by GC-MS/MS. Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and quantum chemical calculations by density-functional theory at B3lYP were used to study the anticorrosive effect of the researched oils on mild steel in 1 M hydrochloric acid solution. Moreover, SEM-EDX analysis was used to identify the surface morphology of mild steel surface. GC-MSMS results showed the presence of 32 potentially active compounds in the EOs of Artemisia herba-alba. The average yield of the EOs was about 1.39 ± 0.17 mL/100 g dry matter. Beta thujone (30.07%) and alpha thujone (13.32%) are the main components, while for the EOs of Juniperus phoenicea, the study showed the presence of 30 constituents, with alpha-pinene (43.61%) and manoyl oxide (11.5%) as the main components. The average yield of HE was 1.10 ± 0.03 mL/100 g dry matter. The findings demonstrated an important anticorrosive action of EOs from Artemisia herba-alba and Juniperus phoenicea. Notably, the experimental results showed good efficiency of the studied essential oils and correlated well with the density-functional theory (DFT) calculations. The results of potentiodynamic polarization measurements showed that hydrazone acted as a mixed-type inhibitor. The EIS results showed an increase in charge transfer resistance accompanied by a noticeable decrease in Cdl values, revealing that both studied oils were effective as reliable inhibitors for the protection of mild steel in 1 M HCl solution. Also, the efficiency decreased with decreasing inhibitor concentrations. Surface studies ensure the effectiveness of both investigated oils and the reduction of the surface roughness of mild steel. Furthermore, DFT results of the major constituents of Artemisia herba-alba and Juniperus phoenicea EOs revealed insights into the chemical reactivity of the tested oils while supporting the experimental conclusions and showed outstanding adsorption ability of both investigated EOs on the steel surface.
