Abstract:

This research aimed to obtain a C-based coating electrochemically applied on an AA6063 alloy. Two electrochemical cells were designed and manufactured to obtain the C-based coating film on flat and cylindrical samples. Structural and microstructural characterizations were performed along with fatigue and corrosion performance testing. The structural and microstructural characterization revealed that the C-based coating deposited on AA6063 corresponded to carbon nanofibers and/or polycrystalline graphite. The performance testing showed an increase in fatigue life along with a decrease in corrosion resistance. The fracture surfaces of the fatigued samples were inspected by Scanning Electron Microscopy and 3D optical microscopy to correlate them with fatigue life estimation. The aforementioned process is a step towards the future development of a complete coating system that will overcome corrosion susceptibility. The carbon film obtained by this electrochemical route has not previously been reported elsewhere.

Abstract:

Here, we report an electrochemical sensor realized using a nanocomposite consisting of nickel hydroxide nanosheets and exfoliated MoS2 nanosheets. The system was able to detect dopamine and α-lipoic acid in phosphate-buffered saline (PBS) solution at a pH of 7.4. The nanocomposites were characterized using microscopic and spectroscopic methods. The electrochemical characterizations were carried out using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). It was observed that Ni(OH)2/MoS2 composite in the weight ratio of 2:1 has better results in terms of electrochemically active surface area, impedance, analytical parameters and stability. The dynamic range for dopamine detection was 0.75 − 95 μM with a LOD value of 56 nM and for α-lipoic acid, the range was 1 − 75 μM and the LOD was 51 nM.

Abstract:

Since their discovery, MXenes have conferred various intriguing features because of their distinctive structures. Focus has been placed on using MXenes in electrochemical energy storage including a supercapacitor showing significant and promising development. However, like other 2D materials, MXene layers unavoidably experience stacking agglomeration because of its great van der Waals forces, which causes a significant loss of electrochemically active sites. With the help of MoS2, a better MXene-based electrodecan is planned to fabricate supercapacitors with the remarkable electrochemical performance. The synthesis of MXene/MoS2 and the ground effects of supercapacitors are currently being analysed by many researchers internationally. The performance of commercial supercapacitors might be improved via electrode architecture. This analysis will support the design of MXene and MoS2 hybrid electrodes for highly effective supercapacitors. Improved electrode capacitance, voltage window and energy density are discussed in this literature study. With a focus on the most recent electrochemical performance of both MXene and MoS2-based electrodes and devices, this review summarises recent developments in materials synthesis and its characterisation. It also helps to identify the difficulties and fresh possibilities MXenes MoS2 and its hybrid heterostructure in this developing field of energy storage. Future choices for constructing supercapacitors will benefit from this review. This review examines the newest developments in MXene/MoS2 supercapacitors, primarily focusing on compiling literature from 2017 through 2022. This review also presents an overview of the design (structures), recent developments, and challenges of the emerging electrode materials, with thoughts on how well such materials function electrochemically in supercapacitors.

Abstract:

Purpose The purpose of this paper is to report on the development of a simple electrochemical nanobiosensor for early detection of pancreatic cancer. The nanobiosensor uses the newly emerged stable micro ribonucleic acid (miR-21) as a cancer-associated biomarker for diagnosis, prognosis or therapy response. Design/methodology/approach The biosensing practice consists of two main steps: capturing probe immobilization on a working electrode modified with multi-walled carbon nanotubes and gold nanoparticles (MWCNTs-AuNPs) and then sensing the miR-21 interaction electrochemically. Two electrochemical techniques, atomic force microscopy and Fourier-transform infrared spectroscopy, were applied for characterizations. Findings The nanobiosensor sensitivity exhibited satisfying results to miR-21 and demonstrated a wide dynamic range with a detection limit of just about 3.68 femtomolar using the source measure unit (SMU). Originality/value Researchers commonly use potentiostats to perform the differential pulse voltammetry (DPV) measurements for the electrochemical biosensing applications. In this study, the SMU was used to perform the DPV to detect the biomarker miR-21 using the MWCNTs-AuNPs screen-printed electrode as the electrochemical system.

Abstract:

Abstract At different calcination conditions, titanium-based manganese oxides (MnOx) electrodes were fabricated by spraying method without adhesive. The MnOx/Ti electrodes were applied in electrochemical oxidation of wastewater treatment for the first time. The surface morphologies of electrodes were tested by scanning electron microscopy. The formation of different manganese oxidation states on electrodes was confirmed by X-ray diffraction and X-ray photoelectron spectroscopy. The electrochemical properties of the electrodes have been performed by means of cyclic voltammetry and electrochemical impedance spectroscopy. The characterizations revealed that the MnOx/Ti-350(20) electrode, prepared at calcination temperature of 350 °C for 20 min, exhibited fewer cracks on the electrode surface, larger electrochemically effective surface area and lower charge transfer resistance than electrodes prepared at other calcination conditions. Moreover, Acid Red B was used as target pollutant to test the electrode activity via monitoring the concentration changes by UV spectrophotometer. The results showed that the MnOx/Ti-350(20) electrode presented the best performance on decolorization of Acid Red B with the lowest cell potential during the process of electrochemical oxidation, and the chemical oxygen demand (COD) conversion was 50.7%. Furthermore, the changes of Acid Red B during the electrochemical oxidation process were proposed by the UV–vis spectra.

Abstract:

In this work, a novel electrochemical sensor was developed by electron-withdrawing substituent modification of 1-phenyl-3-methyl-4-(4-fluorobenzoyl)-5-pyrazolone on a graphene-modified glassy carbon electrode (HPMpFP-graphene/GCE) for glucose detection. The results of characterizations using a scanning electron microscope, Fourier transform infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance spectroscopy showed the successful fabrication of HPMpFP-graphene nanocomposite, which served as an electroactive probe for glucose detection. The electron transfer ability of HPMpFBP-graphene/GCE has been successfully revealed using cyclic voltammetry and electrochemical impedance spectroscopy results. The good electrochemical performance was shown by well-defined peak currents of square wave voltammetry under various parameters, including pH, HPMpFP and graphene composition, and scan rate effect. A high electrochemically evaluated surface area using chronoamperometry suggested that the present glucose detection response was intensified. The chronoamperometry results at a work potential of 0.4 V presented a wide linear range of 1 × 103–90 µM and 88–1 µM with 0.74 µM (S/N = 3) as the detection limit. An acceptable recovery has been revealed in the real sample analysis. The electrochemical sensing behaviour of the composite indicates that it may be a promising candidate for a glucose sensor and it significantly extends the range of applications in the electrochemical field.

Abstract:

Graphene is a highly studied material due to its unique electrical, optical, and mechanical properties. Graphene is widely applied in the field of energy such as in batteries, supercapacitors, and solar cells. The properties of graphene can be further improved by making nanocomposites with conducting polymers. In this work, graphene oxide nanoribbons (GONRs) were synthesized by unzipping multiwall carbon nanotubes. Graphene nanoribbons were used to make nanocomposites with polypyrrole for energy storage applications. The synthesized nanocomposites were structurally and electrochemically characterized to understand their structure and electrochemical properties. The electrochemical characterizations of these nanocomposites were carried out using cyclic voltammetry. The specific capacitance of the nanocomposites was observed to decrease with increasing scan rates. The highest specific capacitance of 2066 F/g was observed using cyclic voltammetry for the optimized nanocomposite of GONR and polypyrrole. Our study suggests that the electrochemical properties of graphene or polypyrrole can be improved by making their composites and that they could be successfully used as electrode materials for energy storage applications. This study can also be extended to the self-assembly of other conducting polymers and graphene nanoribbons through a simple route for various other applications.

Abstract:

Lithium-ion batteries (LIBs) are remarkable electrochemical energy storage systems, which play a critical role in modern society. Demanding new applications have been pushing for further battery advancements, such as developments of all-solid-state and sodium-ion batteries. However, both the LIBs and these new technologies still face challenges that limit their full realization. These include irreversible electrochemical reactions, electrode structure degradations, and surface/interface side reactions. Solving them requires comprehensive characterizations of battery systems over multiple length and time scales. Among the advanced probing techniques, neutron-based ones have unique advantages in exploring battery material structures, ionic diffusions, electrochemical reactions, and cell failure mechanisms, information that will aid the development of next-generation high-performance battery systems. In this Perspective, we briefly review the principles and characteristics of various neutron techniques and their recent applications in battery system studies. Operando neutron characterizations of batteries on spatiotemporal scales and prospects of their future designs and applications are discussed.

Abstract:

A flexible electrochemical sensor based on the carbon felt (CF) functionalized with Bisphenol A (BPA) synthetic receptors was developed. The artificial Bisphenol A receptors were grafted on the CF by a simple thermal polymerization molecular imprinting process. Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and electrochemical characterizations were used to analyze the receptors. Characterization results demonstrated that the Bisphenol A synthetic receptors successfully formed on the CFs surface. Because the synthetic receptor and the porous CFs were successfully combined, the sensor displayed a better current response once Bisphenol A was identified. The sensor’s linear range was determined to be from 0.5 to 8.0 nM and 10.0 to 300.0 nM, with a detection limit of 0.36 nM. Even after being bent and stretched repeatedly, the electrode’s performance was unaffected, demonstrating the robustness, adaptability and viability of installing the sensor on flat or curved surfaces for on-site detection. The designed electrochemical sensor has been used successfully to identify Bisphenol A in milk samples with satisfactory results. This work provided a promising platform for the design of implantable, portable and miniaturized sensors.

Abstract:

A facile hydrothermal strategy was proposed to synthesize RuO2⋅nH2O/mesocarbon microbeads (MCMBs) composites. Further physical characterizations revealed that RuO2⋅nH2O nanoparticles (NPs) were well dispersed upon the surfaces of the MCMB pretreated in 6 M KOH solution. Electrochemical data indicated that the RuO2⋅nH2O/MCMB composites owned higher electrochemical utilization of RuO2species, better power property, and better electrochemical stability, compared with the single RuO2phase. The good dispersion of RuO2⋅nH2O NPs and enhanced electronic conductivity made the H+ions and electrons easily contact the RuO2⋅nH2O phase for efficient energy storage at high rates.

Abstract:

It is necessary to investigate effective energy storage devices that can fulfill the requirements of short-term and long-term durable energy outputs. Here, we report a simple one-pot hydrothermal technique through which to fabricate the MoS2/Te nanocomposite to be used as an effective electrode material for high-performance supercapacitors. Comprehensive characterization of the as-fabricated nanomaterial was performed using FESEM, HRTEM, XRD, FTIR, XPS, etc., as well as electrochemical characterizations. The electrochemical characterization of the as-fabricated nanocomposite electrode material showed a high specific capacitance of 402.53 F g−1 from a galvanostatic charge-discharge (GCD) profile conducted at 1 A g−1 current density. The electrode material also showed significant rate performance with high cyclic stability reaching up to 92.30% under 4000 cycles of galvanostatic charge-discharge profile at a current density of 10 A g−1. The highly encouraging results obtained using this simple synthetic approach demonstrate that the hetero-structured nanocomposite of MoS2/Te electrode material could serve as a promising composite to use in effective supercapacitors or energy storage devices.

Abstract:

Benzylation of the electrochemically generated dianion from N-p-tolyl-[60]fullerooxazolidinone with benzyl bromide provides three products with different addition patterns. The product distribution can be dramatically altered by varying the reaction conditions. Based on spectral characterizations, these products have been assigned as mono-benzylated 1,4-adduct and bis-benzylated 1,2,3,16- and 1,4,9,25-adducts, respectively. The assigned 1,2,3,16-adduct has been further established by X-ray diffraction analysis. It is believed that the 1,4-adduct is obtained by decarboxylative benzylation of the dianionic species, while bis-benzylated 1,2,3,16- and 1,4,9,25-adducts are achieved via a rearrangement process. In addition, the electrochemical properties of these products have been studied.

Abstract:

Solid oxide cells (SOCs) have attracted a growing attention thanks to their high efficiency and ability to operate in both electrolysis (SOEC) and fuel cell (SOFC) modes. Despite its great potential, the current SOC technology faces significant cell degradation during long-term operation. The degradation phenomena are still not well understood as they involve complex and intricate processes arising at different length scales. Additionally, it has been shown that the degradation rate under SOEC operation is generally higher than in SOFC mode. To address this issue, durability tests were performed in SOEC mode at 750, 800 and 850 °C for 2000 h at -1 A cm-2 in 10/90 vol.% H2/H2O and dry air. The electrochemical performance of the cells was assessed using electrochemical impedance spectroscopy. In addition, advanced characterization techniques with nanometer and atomic resolution have been used to study material degradation after long-term testing.

Abstract:

The complex origins of solid-state battery failure call for multidimensional diagnostics utilizing a combination of tools that can quantify the void and dendrite formation, identify the chemical and mechanical natures of the Li dendrites and electrolyte decomposition products. However, there is lack of tools that connect multiple techniques with desirable length scale, resolution and sensitivity for characterizing solid-state batteries. We will present out effort in developing an air-free vessel with an in-situ cell test platform connecting FIB-SEM tomography, ToF-SIMS, and in-SEM nanoindentation for structural, chemical, and mechanical characterizations of solid-state Li batteries. We fabricated solid-state micro-cells with electrochemical performance on par with their bulk-type counterparts. Electrochemical tests with precise temperature control, external pressure, and pressure monitoring of thin solid-state cells were demonstrated with structural, chemical and mechanical characterizations.

Abstract:

Herein, this study shows three different synthesis of gold nanoparticles with various nano-shapes and an investigation of the correlation between nano-shapes and electrochemical effects on dopamine oxidation. To synthesize nano-shaped gold nanoparticles green reducing sources such as rose extract, glucose, and pomegranate juice were used. Thereby, three different gold nanoparticles were synthesized. In order to examine nanoparticle shapes microscopic and spectroscopic characterizations of nanoparticles were carried out. Subsequently the effects of shapes on electrochemical probes and dopamine were accomplished. As a result, it was confirmed that the shapes of the same metal nanoparticles had different effects on electrochemical experiments.

Abstract:

Composite anode material based on Fe3O4 and reduced graphene oxide is prepared by base-catalysed co-precipitation and sonochemical dispersion. Structural and morphological characterizations demonstrate an effective and homogeneous embedding of Fe3O4 nanoparticles in the carbonaceous matrix. Electrochemical characterization highlights specific capacities higher than 1000 mAh g−1 at 1C, while a capacity of 980 mAhg−1 is retained at 4C, with outstanding cycling stability. These results demonstrate a synergistic effect by nanosize morphology of Fe3O4 and inter-particle conductivity of graphene nanosheets, which also contribute to enhancing the mechanical and cycling stability of the electrode. The outstanding capacity delivered at high rates suggests a possible application of the anode material for high-power systems.

Abstract:

In this work, the reaction and nucleation mechanisms of the electrochemical deposition of copper on an indium-doped tin oxide (ITO) conductive glass substrate in a sulfate solution were characterized respectively by electrochemical methods Such as: cyclic voltammetry and chronoamperometry.The transients (current-time) obtained were analyzed by the model of Scharifker and Hills. The deposited copper layer can be described by a model involving instantaneous nucleation at active sites and diffusion controlled 3D growth. The values of the diffusion coefficient D for the Cu2 + ions are also calculated. Electrochemical techniques were followed by morphological characterizations with atomic force microscopy (AFM).All experiments were carried out in an acid solution at pH 4.

Abstract:

This work reports the effects of microstructural changes due to the secondary phases, in particular sigma (σ), on the mechanical properties and electrochemical behavior of thermally aged duplex stainless steel (DSS). Structural, morphological, mechanical, and electrochemical characterizations were performed. Sigma phase content increased with increasing aging treatment time. It had a net-like shape, as observed by electron backscatter diffractometry (EBSD). Its presence directly damaged mechanical properties. The corrosion assessment included electrochemical impedance spectroscopy (EIS) in 1 M NaCl solution at temperatures of 25, 40, and 65 °C. EIS results demonstrate that an increase in the σ phase content decreased the corrosion resistance (21.1–0.8, 3.5–0.3, and 3.1–0.2 kΩ cm2 at 25, 40, and 60 °C, respectively).

Abstract:

Conducting polymer – polypyrrole (PPy) microstructures were fabricated in an aqueous solution of dodecylbenzenesulfonic acid (DBSA) by electrochemical polymerization. The study implied the concentration of DBSA had great effect on the morphologies and conductivities of PPy microstructures. At lower DBSA concentration (0.2M), no obvious microstructures were generated. Increasing DBSA concentration, some novel “chayote-like”, “flower-like” microstructures were obtained by modulating electrochemical conditions. The growth process of microstructures was studied by scanning electron microscopy and relevant mechanism was discussed. Raman characterizations indicated that the microstructures were made of conductive PPy doped by DBSA.
