“…The scan was performed over the 2θ range (10°-80°) at 22.1°C in 0.03° step/scan with an integration time of 1 s/step. The Bragg law (2d sinθ = nλ) was used to calculate the interlayer spacing [37], where d is the interplanar spacing in nm, θ denotes the Braggʼs/ scattering angle in degrees, n is the diffraction order and for rst-order n = 1, and λ is the X-ray wavelength (CuK α radiation = 0.154064 nm). A Fluorolog (Horiba Jobin -Yvon) instrument with a slit width of 5 nm for both excitation and emission was used to perform photoluminescence properties of N-CDs.…”

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...

“…The intelligent impressive strategy of fabricating nanocontainers/nanoreservoirs loaded by inhibitive species as a safe indirect inclusion of corrosion inhibitors into the coatings possesses an on-demand controlled release of the inhibited species as a self-healing activity. In recent years, several nanocontainers have been developed for self-healing functions in anticorrosive coatings such as the spherical carbon hollow sphere (CHS), layered β-cyclodextrin, layered double hydroxides (LDHs), and tubular carbon nanotubes (CNTs) . However, designing efficient nanoreservoirs suitable for the high rate of doping of the organic/inorganic corrosion inhibitors with smart stimuli-responsive as well as barrier functionalities is still an appealing challenge .…”

For the first time, organic tannic acid (TA) molecules and then inorganic praseodymium (Pr) cations as corrosion inhibitors were successfully loaded into a zeolitic imidazolate framework (ZIF8)-type porous coordination polymer (PCP) decorated on molybdenum disulfide, MoS2, (MS)-based transition metal dichalcogenides (TMDs) to create novel hybrid mesoporous Pr/TA-ZIF8@MS nanoreservoirs. Thereafter, the hybrid nanoreservoirs were embedded into the epoxy matrix for the preparation of smart pH-triggered nanocoatings. Characterizations of the Pr/TA-ZIF8@MS nanoreservoirs via Fourier transform infrared (FT-IR), X-ray diffraction (XRD), thermogravimetric (TG), Brunauer–Emmett–Teller (BET), and field emission-scanning electron microscopy (FE-SEM)/energy-dispersive X-ray spectroscopy (EDS) experiments confirmed the fabrication of mesoporous structures comprising Pr/TA interfacial interactions with ZIF8-decorated MS nanoplatelets possessing high thermal stability and compact/dense configuration features with a framework reorientation. A remarkable smart release of the inhibited cations (Pr3+ and Zn2+) in the presence of inbuilt TA at both acidic and alkaline media was achieved under inductively coupled plasma (ICP) examination. The superior pH-triggered self-healing inhibition through the smart controlled-release of Pr, tannate, Zn, and imidazole inhibited species/complexes from EP/Pr-TA-ZIF8@MS via ligand exchange was obtained from electrochemical impedance spectroscopy (EIS) assessments of the scratched coatings during 72 h of saline immersion. In addition, the long-term barrier-induced corrosion prevention (log |Z|10 mHz = 10.49 Ω·cm2 after 63 days) of the EP/Pr-TA-ZIF8@MS was actualized. Moreover, efficient increments of the coating cross-link density (56.45%), tensile strength (63.6%), and toughness value (56.5%) compared to the Neat epoxy coating revealed noticeable thermomechanical properties of the EP/Pr-TA-ZIF8@MS.
