Friction stir processing of pure titanium/nanodiamonds nanocomposites: Microstructure, tribological and corrosion properties

A titanium matrix surface nanocomposite with uniformly distributed nanodiamonds was developed using friction stir process for the first time. A dual phase (α+β) microstructure containing ultrafine equiaxed grains was formed within the matrix after three passes. The mean grain sizes were measured to be 0.7 and 0.9 μm for α and β phase, respectively. The stabilization of the β phase at room temperature was discussed, relying on post-processing cooling rate and the diffusion of W elements from the tool to the matrix. The processed nanocomposite exhibited a microhardness value of 618 Hv in the stir zone, which is 4 and 2.6 times to the initial material and pure Ti processed (without nanodiamonds), respectively. Upon friction stir processing of pure titanium (without nanodiamonds), an ultrafine-grained structure with an average size of 2.4 μm was produced, which led to an increase in microhardness up to 238 Hv. Based on conducted tribological evaluations, the processed surface nanocomposite exhibited a significant decrease in friction coefficient and wear weight loss. The results indicated a 47% decrease in friction coefficient and a 75% reduction in wear weight loss compared to the initial material. The investigation of worn surfaces implied that the wear mechanism was altered from delamination in initial pure Ti to abrasive wear in the Ti/NDs processed nanocomposite. Corrosion testing, including electrochemical impedance spectroscopy and potentiodynamic polarization techniques, revealed that Ti/NDs nanocomposite processing mitigated the material corrosion resistance, which were ascribed to the developed ultrafine grained structure as well as NDs nanoclusters to galvanic corrosion activation.

Synthesis, crystal structure, theoretical calculations, and corrosion study of thiazine[1,5]benzodiazepine

A derivative of 1,5-benzodiazepine, specifically 2-methyl-6-phenyl-2,3-dihydro-1H-[1,3]thiazino[3,2-a]-1,5-benzodiazepin-1-one (TBD), was synthesized by a cyclization [3 + 3] reaction involving the 4-phenyl-1,3-dihydro-2H-1,5-benzodiazepine-2-thione and methacryloylchloride. The structure of TBD was characterized through various spectroscopic methods, including FT-IR, 1H NMR, 13C NMR, and HRMS, also it was confirmed by X-ray analysis. The corrosion inhibitory effectiveness of TBD for mild steel (MS) in 1 M HCl acid was inspected by the exploitation of electrochemical impedance spectroscopy (EIS) and potentiodynamic techniques. Monte Carlo (MC) simulations were employed to study the adsorption behavior of TBD on the Fe (110) surface, providing insights into its inhibitory efficiency against MS corrosion. The simulations were also utilized to calculate the energy of adsorption of the inhibitor onto MS. A comprehensive theoretical investigation, employing density functional theory (DFT) at the B3LYP/6–311 G (d,p) level, was carried out to validate the experimental findings regarding the inhibition properties of the synthesized product and to elucidate the corrosion inhibition mechanism.

Cu corrosion in supernatant and sedimentation of bentonite slurry containing chloride

Cu corrosion in aerated NaCl solution containing different bentonite content was investigated using electrochemical impedance spectroscopy and surface analysis techniques. In NaCl solution, Cu corrosion proceeds with CuClads formation and its transformation to Cu2O. The outer deposit layer consists of Cu2O and Cu2(OH)3Cl. The self-catalyzed comproportionation reaction between Cu and CuClx(x−2)− produces CuClx(x−1)−, leading to accelerated Cu corrosion. Bentonite slurry (10–30 wt%) shows supernatant and sedimentation layers. In supernatant layer, Cu corrosion happens with the help of anions dissolved from bentonite minerals. In sedimentation layer, Cu corrosion is hindered due to suppressed cathodic reaction and the self-catalyzed comproportionation reaction.

Improving inhibition efficiency of 304 stainless steel using an organic extract in acidic and high temperature environment: Experimental and theoretical studies

Many organic inhibitors have been proposed for corrosion protection of 304 stainless steel (SS), but its effectiveness in acidic and high temperature environment is challenged. We utilized Tithonia diversifolia (Hemsl) A. grey leaf extract (TDLE) as an eco-friendly organic inhibitor to protect 304 stainless steel (SS) in acidic environment (1 M HCl) at high temperature (65 °C). The performance of TDLE was studied electrochemically using potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The surface of the metal was characterized using scanning electron microscopy (SEM). The theoretical calculation was also studied to understand the inhibition process. The corrosion inhibition efficiency increases reaching 98.48 % at 65 °C in the presence of 3.5 g/L TDLE. The inhibition of TDLE on 304 SS surface was adsorption spontaneously based in Langmuir's adsorption isotherm. The SEM images show significant improvement of the 304 SS surface with TDLE. A theoretical study indicates that methyl 3.5-dicaffeoyl quinate is the most active inhibitor in TDLE. The study revealed that TDLE had good performance for inhibiting in acidic and high temperature environment.

Methanol electrooxidation performance of nickel-modified polyaniline thin films for direct methanol fuel cells

A metal–organic composite thin film composed of polyaniline (PANI) and Ni was prepared and characterized for methanol electrooxidation reaction. First, PANI thin films were electrodeposited on a fluorine-doped tin oxide (FTO) coated glass support in an aqueous acidic solution. Subsequently, the polymer film was modified with Ni particles (FTO/PANI-Ni) by chronoamperometric (CA) technique. The composite film was characterized by structural, morphological and electrocatalytic analyses. X-ray diffraction (XRD) results confirmed the crystallization of Ni according to the cubic structure. Scanning electron microscopy (SEM) images showed that the Ni nanoparticles were uniformly dispersed on the PANI surface. The electrocatalytic performance of the FTO/PANI-Ni composite electrode for the methanol electrooxidation reaction was investigated in 0.5 M KOH solution containing methanol using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA) techniques. The effects of temperature and methanol concentration on the methanol electrooxidation performance were also studied. The modified composite catalyst exhibited an electrochemically active surface area of 0.5235 cm2. The presence of Ni nanoparticles on the polymer surface promoted the adsorption of methanol molecules and facilitated the oxidation process, leading to higher current densities and better overall performance. The maximum current density was 14 mA cm-2 and the electrode maintain 68 % of its initial activity even after 200 cycles, indicating that the FTO/PANI-Ni electrode exhibited good stability. The high methanol oxidation performance of the composite electrode was associated with large real surface area, a possible synergistic effect between the polymer moleucles and Ni particles as well as high intrinsic activity of Ni for this process.

Novel in-situ encapsulation of tin phosphide particles in MXene conductive networks as anode materials of the durable sodium-ion battery

Sodium-ion battery (SIB) is one of potential alternatives to lithium-ion battery, because of abundant resources and lower price of sodium. High electrical conductivity and long-term durability of MXene are advantageous as the anode material of SIB, but low energy density restricts applications. Tin phosphide possesses high theoretical capacity, low redox potential, and large energy density, but volume expansion reduces its cycling stability. In this study, tin phosphide particles are in-situ encapsulated into MXene conductive networks (SnxPy/MXene) by hydrothermal and phosphorization processes as novel anode materials of SIB. MXene amounts and hydrothermal durations are investigated to evenly distribute SnxPy in MXene. After 100 cycles, SnxPy/MXene reaches high specific capacities of 438.8 and 314.1 mAh/g at 0.2 and 1.0 A/g, respectively. The capacity retentions of 6.0% and 73.6% at 0.2 A/g are respectively obtained by SnxPy and SnxPy/MXene. The better specific capacity and cycling stability of SnxPy/MXene are attributed to less volume expansion of SnxPy during charge/discharge processes and relieved self-stacking of MXene by encapsulating SnxPy particles between MXene layers. Electrochemical impedance spectroscopy and Galvanostatic intermittent titration technique are also applied to analyze the charge storage mechanism in SIB. Higher sodium ion diffusion coefficient and smaller charge-transfer resistance are obtained by SnxPy/MXene.

Electrochemical supercapacitors, one of the storage devices, have attracted much attention owing to their high power density, fast charge-discharge and long cycle life. In this study, we present findings of a hybrid system comprised of gold and polyaniline, fabricated via an in-situ, one pot synthesis route and designed for use in symmetric supercapacitor applications. The gold-polyaniline (Au-PANI) based hybrid material was thoroughly characterized using microscopic, optical, and surface analytical techniques to gain a comprehensive understanding of the system. The electrochemical performance of Au-PANI based electrode was examined using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) techniques. The hybrid system exhibited maximum specific capacitance (CS) 387 F/g at the current density of 12 A/g for three electrode system. The symmetric supercapacitor exhibited a maximum specific capacity (QS) 303 mAh/g at the current density of 0.1 A/g and achieved a maximum energy density (ED) and power density (PD) of 243 mWh/kg and 619 W/kg at the current density of 0.1 A/g and 0.9 A/g, respectively. Further, the Au-PANI based symmetric device was applied to generate low-frequency waveforms.

Production of Sulphur-Doped Graphene Oxide as an Anode Material for Na-Ion Batteries

Sodium-ion batteries have been the focus of interest in recent years due to abundance and cost-effectiveness of sodium resources globally as opposed to lithium. In this work, sulfur-doped graphene oxide (SGO) was synthesized using a straightforward, one-step, cost-effective, and eco-friendly chronoamperometric method at room temperature. The resulting powder was then utilized as active anode material for Na-ion batteries. The surface of the synthesized SGO powder, which consists of approximately three layers with 19 sp2 hybridized carbon rings and a domain size of about 50 nm, is covalently doped with –C-SOx-C- (x = 2,3) groups. The deduced diffusion coefficient from electrochemical impedance spectroscopy and galvanostatic intermittent titration technique measurements for SGO as anode in NIBs is in the range of 10−11–10−12 cm2.s−1. At 0.1 C rate, the initial discharge capacity recorded 256.7 mAh.g−1 at 0.1 C rate. In addition, the capacity retention for long-term cycling of 100 cycles at 2 C rate was 99.85%. The unique structure of SGO allows us to achieve satisfactory anode performance in capacity and rate capability, with potential for further enhancement.

Intercalation of decanoate anions (C10) in layered double hydroxide Mg[sbnd]Al and its application as controlled-release corrosion inhibitor of steel

This study focuses on the preparation and characterization of a novel anticorrosion pigment based on decanoate anions (C10‐) intercalated within layered double hydroxide (LDH) MgAl. The LDH-NO3, LDH-C10 were synthesized by a simple co-precipitation method and analyzed by XRD, infrared spectroscopy, thermogravimetry and electronic microscopy. The LDH-C10 pigment with a basal distance of about 20 Å was consistent with the arrangement of C10 anions in bilayer. The inhibition efficiency of the LDH-C10 pigment in electrolyte and in alkyd resin paint was studied by electrochemical impedance spectroscopy and potentiodynamic techniques. The pigments act as a C10− nanocontainer, which release the C10− anions in contact with chloride ions that lead to the formation of a passive layer on steel. In alkyd resin, the LDH-C10-enriched organic coating exhibit very interesting anticorrosive performance in NaCl electrolyte during 40 days of immersion.

EVALUATING ACETONE AND METHANOL FOR ELECTROPHORETIC DEPOSITION OF SS 316L COATED WITH HYDROXYAPATITE/MULTIWALLED CARBON NANOTUBES DENTAL IMPLANTS: A FOCUS ON CORROSION RESISTANCE

Dental implants offer a reliable solution for replacing damaged tooth roots. This research investigates the comparative performance of acetone and methanol as suspension media in the fabrication of stainless steel type 316L-based dental implants using the Electrophoretic Deposition (EPD) method, a technique known for its simplicity and cost-effectiveness. Voltage variations of 20V, 30V, and 40V were applied to both acetone and methanol suspensions for a duration of 20 minutes. The morphology of the Hydroxyapatite/Multiwalled Carbon Nanotube (HA/MWCNT) coatings was meticulously characterized using Scanning Electron Microscopy (SEM). Corrosion resistance was evaluated through Potentiodynamic Polarization (PDP) and Electrochemical Impedance Spectroscopy (EIS) techniques. Remarkably, at 30V, a homogeneous and crack-free coating was achieved, demonstrating superior corrosion resistance. This was further corroborated by the resistance values of 23.891 Ω and 114.990 Ω for the acetone and methanol samples, respectively. Additionally, the corrosion rates of 0.075 (mmpy) and 0.0004 (mmpy) for the acetone and methanol samples further emphasized the superiority of methanol as a suspension medium. These findings unequivocally establish methanol as the optimal choice for achieving superior deposition quality and corrosion resistance in the context of the EPD method for stainless steel type 316L-based dental implants.

Non-Faradaic Impedimetric Detection of Heavy Metal Ions via a Hybrid Nanoparticle-DNAzyme Biosensor.

Due to rapid industrialization, novel water-quality monitoring techniques for the detection of highly toxic and hazardous heavy metal ions are essential. Herein, a hybrid noble nanoparticle/DNAzyme electrochemical biosensor is proposed for the simultaneous and label-free detection of Pb2+ and Cr3+ in aqueous solutions. The sensor is based on the combination of a two-dimensional naked-platinum nanoparticle film and DNAzymes, whose double-helix configuration disassembles into smaller fragments in the presence of target-specific heavy metal ions. The electrochemical behavior of the fabricated sensor was investigated with non-faradaic electrochemical impedance spectroscopy (EIS), resulting in the successful detection of Pb2+ and Cr3+ well below their maximum permitted levels in tap water. So far, there has been no report on the successful detection of heavy metal ions utilizing the non-faradaic electrochemical impedance spectroscopy technique based on advanced nanomaterials paired with DNAzymes. This is also one of the few reports on the successful detection of chromium (III) via a sensor incorporating DNAzymes.

Abstract Electrodialysis (ED) and electrodeionization (EDI) are the new methods that are being used in water desalination processes. Reliable, electrochemically stable and efficient electrodes are the crucial components of the ED/EDI electrodialysers. The article proposes a new material for electrodes in electromembrane desalination systems. Graphene composite electrodes were created by bonding carbon fibres with epoxy resin and then coated with a layer of nanostructured, reduced graphene oxide. The graphene electrode material underwent electrochemical characterization by cyclic voltammetry, electrochemical impedance spectroscopy and potentiostatic polarization techniques. FTIR and Raman spectroscopy were used to determine the material’s chemical structure. The change in the surface morphology and elemental composition of the electrodes after fabrication and exploitation of the composite was studied by SEM and EDS. The electrodes were used successfully in multi-electrode electrodialysis devices, resulting in a desalination rate of over 90%. The electrodes were proven to be functional and durable. It was also confirmed that the oxidation/reduction phenomena on the electrode surfaces were fully reversible after changing their polarization, which was used cyclically to clean the electrodialyser. The parameters obtained indicate that this material can also be successfully used in other electrode processes. Graphical Abstract

Solvothermal Synthesis of Cu2ZnSnSe4 Nanoparticles and Their Visible-Light-Driven Photocatalytic Activity.

Cu2ZnSnSe4 (CZTSe) nanoparticles (NPs) were successfully synthesized via a solvothermal method. Their structural, compositional, morphological, optoelectronic, and electrochemical properties have been characterized by X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Field-emission scanning electron microscopy (FE-SEM), transmission electron microscope (TEM), UV-vis absorption spectroscopy, and electrochemical impedance spectroscopy (EIS) techniques. Porosimetry and specific surface area in terms of the Brunauer-Emmett-Teller (BET) technique have also been studied. XRD indicates the formation of a polycrystalline kesterite CZTSe phase. Raman peaks at 173 and 190 cm-1 confirm the formation of a pure phase. TEM micrographs revealed the presence of nanoparticles with average sizes of ~90 nm. A BET surface area of 7 m2/g was determined. The CZTSe NPs showed a bandgap of 1.0 eV and a p-type semiconducting behavior. As a proof of concept, for the first time, the CZTSe NPs have been used as a visible-light-driven photocatalyst to Congo red (CR) azo dye degradation. The nanophotocatalyst material under simulated sunlight results in almost complete degradation (96%) of CR dye after 70 min, following a pseudo-second-order kinetic model (rate constant of 0.334 min-1). The prepared CZTSe was reusable and can be repeatedly used to remove CR dye from aqueous solutions.

Nanoconstructs of gold nanoparticles (AuNPs) conjugated with SARS-CoV-2 specific antisense oligonucleotides (ASO) have been utilized to develop sensitive electrochemical nucleic acid biosensor for the detection of SARS-CoV-2 RNA. AuNPs were prepared through a one-pot synthesis method by utilizing Poly-L-Lysine (PLL) biopolymer and as synthesised AuNP were characterized by various analytical techniques such as UV–Vis spectroscopy, X-ray Diffraction (XRD) analysis, Fourier Transform Infra-Red spectroscopy (FT-IR), zeta potential, and Transmission Electron Microscopy (TEM). Poly-L-Lysine functionalized AuNPs (PLL-AuNPs) nanoconstructs platform was employed for immobilization of SARS-CoV-2 specific antisense oligonucleotides (ASO-conjugated PLL-AuNPs) via electrostatic interactions. The PLL-AuNPs were drop casted on glassy carbon electrode (GCE) following immobilization of ASO for fabrication of electrochemical biosensor. The ASO-conjugated PLL-AuNPs nanoconstructs were characterized by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS) techniques. The responsiveness of ASO-conjugated PLL-AuNPs nanoconstructs in presence SARS-CoV-2 RNA was monitored using the DPV, SWV and EIS technique, where methylene blue was employed as an electrochemical indicator for DNA-RNA hybridization detection. The biosensor exhibits a detection range for SARS-CoV-2 RNA infection ranging from 0 to 100 nM, with a limit of detection at 30.2 nM. The electrode, modified with ASO-conjugated PLL-AuNPs, was employed for the detection of SARS-CoV-2 RNA from clinical samples collected from COVID-19-positive individuals.

Retardation of the C-Steel Destruction in Hydrochloric Acid Media Utilizing an Effective Schiff Base Inhibitor: Experimental and Theoretical Computations.

The corrosion inhibition of (N 1 E)-N 1,N 2-bis(4-(dimethylamino)benzylidene)-ethane-1,2-diamine, DMAB, against the destruction of C-steel in dilute HCl media (1.0 M) was examined. The techniques of gravimetry, gasometry, potentiodynamic, and electrochemical impedance spectroscopy are utilized. The rate of corrosion is found to decrease with more additions of the DMAB compound. The inhibition efficacy increases with concentrations to reach 97.7% at 5.0 mM and 298 K. The protection of metal destruction is controlled by the adsorption of the DMAB molecules on the metallic surface obeying Langmuir's pattern. The computed ΔG°ads values are characterized by negative sign, explaining the spontaneity of the adsorption process. These values vary between -38.70 and -35.13 kJ mol-1 depending on the temperature, which proves the physio- and chemisorption mechanisms. The reduction in K ads values with T can be attributed to the desorption of some DMAB molecules from the electrode surface. Theoretical quantum computation confirms the adsorption of the DMAB compound in concurrence with the data obtained by practical techniques.

Due to its higher selectivity and long term stability, the composite electrode was applied to the detection of ACP in pharmaceutical formulations.

One-Step Hydrothermal Synthesis of Sn-Doped Sb2Se3 for Solar Hydrogen Production.

Antimony selenide (Sb2Se3) has recently been intensively investigated and has achieved significant advancement in photoelectrochemical (PEC) water splitting. In this work, a facile one-step hydrothermal method for the preparation of Sn-doped Sb2Se3 photocathodes with improved PEC performance was investigated. We present an in-depth study of the performance enhancement in Sn-doped Sb2Se3 photocathodes using capacitance-voltage (CV), drive-level capacitance profiling (DLCP), and electrochemical impedance spectroscopy (EIS) techniques. The incorporation of Sn2+ into the Sb2Se3 results in increased carrier density, reduced surface defects, and improved charge separation, thereby leading to improved PEC performance. With a thin Sb2Se3 absorber layer (270 nm thickness), the Sn-doped Sb2Se3 photocathode exhibits an improved photocurrent density of 17.1 mA cm-2 at 0 V versus RHE (V RHE) compared to that of the undoped Sb2Se3 photocathode (14.4 mA cm-2). This work not only highlights the positive influence of Sn doping on Sb2Se3 photocathodes but also showcases a one-step method to synthesize doped Sb2Se3 with improved optoelectronic properties.

In the proposed method using optimized experimental conditions, two different linearities were obtained for DAB in the concentration range of 0.04–0.8 μM and 1.0–10.0 μM. The LOD value obtained is 0.014 μM. In this study, the resulting electrochemical sensor was applied for the first time to investigate the electrochemical behavior of DAB with high sensitivity and reproducibility, as well as the possible electrochemical oxidation mechanism.

Protection of mild steel from corrosion in HCl solution via green Rumex acetosella extract: Experimental and theoretical studies

The efficiency and potential of green Rumex acetosella extract (RAE) on the inhibition of the mild steel (MS) corrosion were investigated in the acidic environment. The high inhibitive capability of RAE on the mild steel was studied by electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) techniques. In addition, potentiodynamic (PD) polarization measurements were carried out to examine corrosion mechanism. The achieved electrochemical tests showed that RAE has a significant inhibition effect on mild steel corrosion. The results of surface analysis recorded by scanning electron microscopy (SEM), and atomic force microscopy (AFM) depicted that RAE provide strong protective layer on the steel surface via adsorptive groups. The inhibition efficiency was calculated as 99.7 %, and 99.6 % from LPR and EIS after 120 h exposure time. Adsorption free energy (∆Gadso) value is found as −29.79 kJ mol−1, indicating that both physical and chemical adsorptions occur. Furthermore, the obtained experimental findings were supported with quantum chemical calculation results.

Eco-friendly corrosion inhibition of steel in acid pickling using Prunus domestica Seeds and Okra stems extracts

The corrosion inhibition process during acid pickling in petroleum industries often employs toxic chemicals, facing stringent environmental regulations. This study explores a sustainable alternative by investigating the inhibitory effects of eco-friendly food waste extracts, namely Prunus domestica seeds (P.S) and Okra stems (O.St), on B7 grade steel corrosion in 1.0 M HCl aqueous solution, simulating an acid pickling environment. The corrosion inhibition efficiency was estimated via both electrochemical methods, including electrochemical impedance spectroscopy and potentiodynamic polarization techniques, and chemical methods, such as weight loss measurements. Fourier transform infrared spectroscopy (FTIR) and Gas chromatography-mass spectrometry (GC-MS) elucidated the extracts' main functional groups and potential chemical constituents. Remarkably, both extracts exhibited a maximum inhibitory efficiency of up to 80 %. Adsorption isotherms were employed to analyze the inhibition mechanisms, including Langmuir and Flory–Huggins models, alongside the Kinetic-thermodynamic model. Activation parameters have been obtained using Arrhenius and transition state equations. The synthesis of the activated complex is characterized as an endothermic process, as evidenced by the positive values of enthalpy of activation (ΔH*). Conversely, negative entropy of activation (ΔS*) values indicate that the activated complex signifies a process of association rather than separation. Quantum chemical calculations identified potential active inhibitor compounds within the extracts. The quantum parameters, including ionization potential, electronegativity, softness, and hardness of the chemical constituents of the extracts, were calculated using DFT with the B3LYP/6–31 G(+) method. This study underscores the innovative approach of utilizing waste food extracts as corrosion inhibitors, addressing environmental concerns while offering practical implications for industrial applications.
