Ce-MOF@Au-Based Electrochemical Immunosensor for Apolipoprotein A1 Detection Using Nanobody Technology.

Apolipoprotein A1 (Apo-A1) is a well-recognized biomarker in tissues, closely associated with cardiovascular diseases such as atherosclerosis, coronary artery disease, and heart failure. However, existing methods for Apo-A1 determination are limited by costly equipment and intricate operational procedures. Given the distinct advantages of electrochemical immunosensors, including affordability and high sensitivity, along with the unique attributes of nanobodies (Nbs), such as enhanced specificity and better tissue permeability, we developed an electrochemical immunosensor for Apo-A1 detection utilizing Nb technology. In our study, Ce-MOF@AuNPs nanocomposites were synthesized by using ultrasonic methods and applied to modify a glassy carbon electrode. The Nb6, screened from an Apo-A1 immunized phage library, was immobilized onto the nanocomposite material, establishing a robust binding interaction with Apo-A1. The recorded peak current values demonstrated a logarithmic increase corresponding to Apo-A1 concentrations ranging from 1 to 100,000 pg/mL, with a detection limit of 36 fg/mL. Additionally, the developed immunosensors demonstrated high selectivity, good stability, and reproducibility. Our methodology was also effectively utilized for serum sample analysis, showing good performance in clinical assessments. This electrochemical immunosensor represents a promising tool for Apo-A1 detection, with significant potential for advancing cardiovascular disease diagnostics.

Minimally Invasive Real-Time Monitoring for Rapid and Sensitive Diagnosis of Spinal Cord Injury.

Spinal cord injury (SCI) is a serious neurological injury that is currently extremely difficult to cure clinically. SCI involves numerous pathophysiological processes, and microRNAs (miRNAs) play an important role in these processes. Meanwhile, miRNAs have received a lot of attention for their role in other diseases as well. Therefore, the detection of disease-related miRNAs is important for the study of disease development, treatment, and prognosis. With the rapid development of molecular biology, the traditional detection methods of miRNA can no longer meet the needs of experiments. Electrochemical detection methods are widely used because of their excellent detection performance. Here, we designed an electrochemical sensor prepared using borosilicate glass microneedle electrodes for real-time monitoring of miR-21-5p expression in vivo after SCI. The sensor showed a good linear relationship between the oxidation peak current value and the concentration of miR-21-5p in the concentration range 0-2 fM (Y = 12.025X + 90.396, R2 = 0.98). The limit of detection (LOD) of the sensor was 0.3667 fM. The experimental results showed that the borosilicate glass microneedle electrochemical sensor achieved fast, accurate, highly sensitive, highly specific, highly stable, and reproducible monitoring of miR-21-5p. More importantly, the electrochemical sensor has a better clinical translation prospect, which is important for the research of clinical diseases.

Development of inductive energy storage pulsed power supply using SiC semiconductor devices for ozone production by streamer discharges

Abstract Inductive energy storage (IES) pulsed power generator driven by the silicon carbide (SiC)-MOSFET with the blocking voltage of 1.2 kV was developed. The IES pulsed power generator consists of a capacitor, a pulsed transformer and the SiC-MOSFET used as an opening switch. The influence of turn ratio of the pulsed transformer on the output voltage was evaluated. The amplitude of output voltage increased with increasing the secondary turn ratio. Under the conditions of no lord , a peak output voltage of 13 kV and a pulse width of 120 ns were obtained with a voltage across the drain-source terminals of the MOSFET of 1kV with no lord. The peak voltage value increased, and the peak current and pulse width value decreased with increasing load resistance and decreased capacitance. The maximum energy transfer efficiency was obtained with 500 Ω and was Approximately 56%.

Noncirculating current series resonant converter with pulse frequency modulation

SummaryIn this paper, an asymmetric pulse frequency modulation (APFM) is applied to the full‐bridge series resonant converter with a secondary LC resonant tank. Different from the traditional PFM, the upper and lower switches have complementary gate drivers and the lower switches have constant on time of half‐resonant period in this paper. Thanks to the resonant tank moved to the secondary side with the adopted APFM, the maximum magnetic flux density Bm of a high‐frequency transformer (HFT) is only concerned with the fixed resonant frequency rather than the variable switching frequency. Hence, the switching frequency can be widely regulated, as well as the voltage gain. Furthermore, the circulating current flowing back to the input voltage source in the traditional LC series resonant converter can be eliminated by the APFM, leading to a low resonant current peak value. The operation principles and characteristics of the adopted method are analyzed in detail. Finally, a 500 W/70–120 V to 300 V/21–180 kHz prototype is built, and the experimental results verified the theoretical analysis well.

Influence of Voltage Rising Time on the Characteristics of a Pulsed Discharge in Air in Contact with Water: Experimental and 2D Fluid Simulation Study

In the context of plasma–liquid interactions, the phase of discharge ignition is of great importance as it may influence the properties of the produced plasma. Herein, we investigated the influence of voltage rising time (τrise) on discharge ignition in air as well as on discharge propagation on the surface of water. Experimentally, τrise was adjusted to 0.1, 0.4, 0.6, and 0.8 kV/ns using a nanosecond high-voltage pulser, and discharges were characterized using voltage/current probes and an ICCD camera. Faster ignition, higher breakdown voltage, and greater discharge current (peak value) were observed at higher τrise. ICCD images revealed that higher τrise also promoted the formation of more filaments, with increased radial propagation over the water surface. To further understand these discharges, a previously developed 2D fluid model was used to simulate discharge ignition and propagation under various τrise conditions. The simulation provided the spatiotemporal evolution of the E-field, electron density, and surface charge density. The trend of the simulated position of the ionization front is similar to that observed experimentally. Furthermore, rapid vertical propagation (<1 ns) of the discharge towards the liquid surface was observed. As τrise increased, the velocity of discharge propagation towards the liquid increased. Higher τrise values also led to more charges in the ionization front propagating at the water surface. The discharge ceased to propagate when the charge number in the ionization front reached 0.5 × 108 charges, irrespective of the τrise value.

Bifunctional properties of Ag/α-Fe2O3/rGO nanocomposite for supercapacitor and electrochemical nitrate sensing using tetradodecyl ammonium nitrate as ion-selective membrane.

Noble metal nanoparticles incorporated in hybrid nanocomposites are considered as promising candidates for electrochemical applications owing to their physicochemical properties. In this work, we demonstrated the preparation of Fe2O3/rGO nanocomposite by hydrothermal method, followed by in situ Ag binding synthesis for the fabrication of hybrid nanocomposite (Ag/α-Fe2O3/rGO). The crystallographic structure of the hybrid nanocomposite is examined by X-ray diffraction (XRD) analysis which confirms the characteristics of Ag, Fe2O3, and rGO. The microscopic studies and energy-dispersive X-ray analysis (EDS) spectra confirmed the presence and formation of hybrid nanostructures. Raman analysis results further corroborate the formation of composite with significant D and G bands in Fe2O3/rGO and Ag/α-Fe2O3/rGO samples, which follow XRD results. Cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) studies were carried out to analyze the faradaic capacitor behavior. A specific capacitance of 209.09 F/g was observed by GCD studies for Ag/α-Fe2O3/rGO composites at a current density of 1 A/g, which exhibited good capacitance retention of 94% for 5000 cycles at 7 A/g. Furthermore, the Ag/α-Fe2O3/rGO electrode was used for the electrochemical detection of nitrate ions in soil by utilizing an ion-selective membrane over the surface of the Ag/α-Fe2O3/rGO electrode. The fabricated nanocomposite electrode showed a significant change in the peak current values with the concentration of nitrate in a linear range from 10 to 450μM with the sensitivity to be calculated 1.426 μA μM-1cm-2 and limit of detection (LOD) calculated to be 0.18μM. The reproducibility and interference studies showed a promising result to be utilized for detecting nitrate ions in soil and in real-time applications.

Assessment of Recast Layer while Machining Die Steel D3 on EDM

The material melted and quickly solidified on the surface, forming a Recast layer over the machined surface. The present experimental assessment measures the extent of influence of machine variables towards the deposition of recast material post-machining Die Steel D3. The microstructure of the recast layer is dendritic and columnar due to sudden quenching, causing complex phase transformation. Scanning Electron Microscopy is utilized to assess the range of recast deposition. The range of average recast deposition is between 32.7 to 68.5 µm. The sequential model and lack of fit tests depict that the EDM parameters and recast layer can be modeled using 2FI equations. The analysis apprised that peak current (p-value < 0.0001) has a crucial impact on recast deposition. The duration (p-value = 0.4694) was the minimal affecting factor amid selected variables for white layer thickness, which aligns with the previous literature. The impact of current and duration is almost linear towards recast layer thickness and higher deposits of recast layer (RL) are observed at higher levels of current and duration. Lower RL can only be attained by setting a lower current and on duration. The influence of lower voltage is not much on recast layer thickness at minimum value of peak current. The residual error of 3.13% during model validation illustrates the adequacy of the model.

Electrochemical chiral sensor developed using nanofibrous polyaniline chiral Structures: Detection and differentiation of D- and L-tryptophan

In this work, a simple strategy for electrochemical detection and differentiation of D- and L- forms of tryptophan is demonstrated using nanofibrous structures of chiral polyaniline (CP). Basically, CP with desired chirality is prepared using a chiral acid namely, ± camphor sulfonic acid (±CSA) in presence of either a cationic (or) anionic surfactant (CTAB / SDS) through a simple oxidative polymerization process. Structure, morphology and phase purity of the resultant CP materials are characterized by field emission scanning electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray diffraction studies. Moreover, the chiral properties of these conducting polymers are evaluated using circular dichroism (CD) spectroscopic studies. From these analyses it is found that CP exhibited twisted nanofibrous morphology and possesses the chirality whereas the non-chiral polyaniline (PANI), prepared in the absence of chiral acid, displayed the formation of a simple fibrous structures without any twists or chirality. Interestingly, such CP materials are found to be electrochemically selective for the detection and differentiation of D- and L- forms of tryptophan (Trp). Among the different chiral materials, CP-CT(−) prepared using CTAB displayed a much better sensing characteristics with higher IL/ID ratio, wider concentration range of detection and lower detection limit of 0.98 µM for l-Trp and 1.2 µM for d-Trp respectively. On the other hand, non-chiral PANI does not display any sensing behavior towards the differentiation of amino acid, Trp. Further, chronoamperometric studies reveal the selectivity of this chiral sensor for the detection of Trp among the other potentially interfering analytes. Although the difference in the measured peak current value is smaller, a significant difference of 70 mV peak potential is observed for the differentiation of L- and d-Trp. Moreover, the proposed CP-based sensing platform exhibits excellent stability and reproducibility with statistically negligible error values suggesting the potential use of the developed material towards electrochemical chiral detection and differentiation of amino acid, Trp.

In this study, activated carbon (AC) is synthesized from waste thermocol sheets and functionalized it with amine groups to enhance the surface properties and selectivity. The synthesized material is further characterized using X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and X-ray Photoelectron Spectroscopy (XPS). SEM images revealed excellent porosity, XRD confirmed AC synthesis, and FTIR and XPS verified amine functionalization. The size of particles of the synthesized material is determined to be 38.4 nm using Dynamic Light Scattering (DLS). The modified carbon is used as a working electrode in an innovative portable electrochemical sensing prototype for detecting 2-chloroethyl Phenyl Sulphide (2-CEPS). Electrochemical characterizations, including cyclic voltammetry (CV) and differential pulse voltammetry (DPV), were conducted to evaluate the electrode's performance. Studies on analyte concentration effects, calibration plots, reproducibility, and stability were also performed. The prototype demonstrated a limit of detection (LOD) of 82.89 µM and a limit of quantification (LOQ) of 251.18 µM, with a linear range of 50-300 µM. Stability tests using 150 µM of 2-CEPS at pH 6 showed consistent peak current values, indicating the device's reliability. The prototype is cost-efficient, portable, and suitable for onsite detection of 2-CEPS, with potential applications in environmental monitoring, war zones, emergency response, border security, and industrial safety.

Natural deep eutectic solvent-supported exfoliated graphite nanoplatelet-based electrochemical sensor for the determination of tyramine in fermented beverages

A novel electrochemical sensor was developed for the determination of tyramine. The sensor was constructed by modifying the surface of a glassy carbon electrode (GCE) with a film composed of exfoliated graphite nanoplatelets (xGnPs) dispersed in a natural deep eutectic solvent (NADES). The NADES was prepared by simply mixing equimolar amounts of caprylic acid and menthol and heating at 80 °C for 30 minutes. Characterization studies confirmed the formation of a NADES through the attenuated total reflectance-Fourier transform infrared spectroscopy technique, while transmission electron microscopy demonstrated the ability of the NADES to disperse the xGnPs. Electrochemical impedance spectroscopy data showed that the modified sensor exhibited lower resistivity than the unmodified electrode. By optimizing the parameters of square wave voltammetry and experimental conditions to obtain the highest peak current values for tyramine oxidation, a calibration curve was constructed in a 0.1 mol L−1 phosphate buffer (pH 7.0), obtaining detection and quantification limits of 0.06 and 0.20 mg L−1, respectively. Finally, the sensor was successfully applied to the determination of tyramine in fermented milk, beer, and non-alcoholic beer samples, with satisfactory recovery data.

Synergistic effects of coordinated metals and fluoridation in metal-covalent organic framework for efficient triboelectric nanogenerator

Improving the performance of triboelectric nanogenerators (TENG) depends on the development of new and effective friction electrode materials. Metal-covalent organic frameworks (MCOFs) are promising functional materials with applications in various fields owing to their structural diversity and tunability; howerver, the use of MCOFs in the preparation of TENG devices has not yet been investigated. In this study, a MCOF (Cu-COF) was designed and constructed via the post-metalation method by introducing transition metal ions through the delicate chelating structure of a CF3 substituted covalent organic framework (CF3-COF) for the first time. The constructed Cu-COF exhibited higher triboelectric nanogenerator output performance, with a peak value of short circuit current of 104.0 µA and an output voltage of 1107 V, which are 1.47 and 1.39 times those of CF3-COF, respectively. This can be attributed to the excellent charge density, improved conductivity and narrow band gap of Cu-COF. In addition, the Cu-COF-based TENG exhibits excellent stability and power density, and is capable of lighting 1440 commercial green LEDs. This study also suggests that the strategy for engineering metalation coordination environments on the skeletons of COFs could provide a novel method to fabricate TENG devices with MCOFs.

Physics-based 3D simulation of single event transient current in GaN high-electron-mobility transistor and super-heterojunction field-effect transistor

Physics-based 3D simulations were conducted on a GaN high-electron-mobility transistor (HEMT) and a super-heterojunction field-effect transistor (SHJFET) to investigate the single event effect mechanism under heavy ion irradiation. Most of the single event transient current in HEMT was attributed to the punch-through effect in the bulk caused by the local increase in electrostatic potential. With improved E-field management and a more favorable potential profile to suppress source electron injection, the SHJFET had a 70% lower transient current peak value compared to the HEMT.

Taurine-Functionalized Carbon Nanotubes as Electrode Catalysts for Improvement in the Performance of Vanadium Redox Flow Battery

The vanadium redox flow battery (VRFB) is a highly favorable tool for storing renewable energy, and the catalytic activity of electrode materials is crucial for its development. Taurine-functionalized carbon nanotubes (CNTs) were prepared with the aim of augmenting the redox process of vanadium ions and enhancing the efficiency of the VRFB. Sulfonated CNTs were synthesized through a simple modification process in a taurine solution and used as electrocatalysts for redox reactions involving VO2+/VO2+ and V2+/V3+. The SO3H-CNTs modified at 60 °C for 2 h exhibit the best electrocatalytic activity, showing higher redox peak current values compared to pristine carboxylated CNTs (COOH-CNTs). Sulfonic acid groups added to the surface of CNTs increase active sites for redox reactions and act as carriers for mass transfer and bridges for charge transfer, accelerating the rate of the electrode reactions. A battery consisting of SO3H-CNTs as catalysts demonstrates the outstanding charge–discharge performance at a current density of 300 mA∙cm−2. This configuration displays voltage and energy efficiencies of 81.46% and 78.83%, respectively, representing enhancements of 6.15% and 6.12% compared to that equipped with conventional graphite felts (75.31%, 72.71%). This study illustrates that taurine-functionalized carbon nanotubes serve as an efficient and promising catalyst for both the anode and cathode, leading to the improved performance of the VRFB.

Ultrasonic synthesis of borophene as a 2D electrode material with high electrocatalytic activity for use in fuel cell applications

Green energy systems must be able to provide a significant proportion of the energy needed to meet the ever-increasing demand for energy. Fuel cells are a promising solution to bridge the gap in the green energy transition. This study aims to enhance the energy efficiency of fuel cells by utilizing 2D supported nanocatalysts in the anode compartment. Borophene was synthesized using the liquid phase exfoliation method to be used as a support structure due to its superior properties. To use borophene as a supporting material in methanol fuel cells, a borophene-palladium hybrid structure (Pd@Borophene) was prepared using the chemical reduction method. The scanning electron microscopy (SEM) images showed that the obtained particle had a partially formed layered structure. The electrocatalytic activity of the Pd@Borophene was investigated through anodic reactions in Direct Methanol Alcohol Fuel Cells (DMFC). Electrochemical analyses were conducted to compare the effect of borophene on Pd and Pd@borophene nanocatalysts on the anodic reaction. The anodic peak current value of methanol oxidation for Pd@borophene was found to be 24.3 mA/cm2, which is approximately four times higher than that of unsupported Pd nanoparticles. Additionally, the ratio of forward current (If) to reverse current (Ib), which serves as an indicator of catalyst poisoning, was determined to be 2.27. This study contributes significant findings to the literature by demonstrating that borophene, an advanced 2D material, can be synthesized using a low-cost liquid phase exfoliation method and can be utilized in fuel cell applications for energy generation.

Effect of pulse time (Ton), pause time (Toff), peak current (Ip) on MRR and surface roughness of Cu–Al–Mn ternary shape memory alloy using wire EDM

Shape memory and super elasticity are two outstanding properties of Cu–Al–Mn SMAs together with additional copper-based shape memory alloys that make them superior to NiTi alloys. It's quite hard to machine Cu–Al–Mn SMA. The machinability properties of Cu–Al–Mn SMAs during Wire Electrical Discharge Machining (WEDM) were experimentally investigated using molybdenum wire as the electrode material. Material Removal Rate (MRR) and Surface Roughness (SR) are two machining qualities that are studied in relation to the combinational values of pulse time (Ton), pause time (Toff), and peak current (Ip), which are selected as the changeable input process factors. From the experimental investigation, it was found that both MRR and Ra values were increased with an increase in pulse on time(Ton), pulse off time(Toff), and peak current (IP)values. Because the wire electrode contains maximum current under these conditions, it is easy to remove more material at the tool and work material interface, resulting in moderate surface finish. Surface quality was higher on samples machined at low energy input than it was on samples machined at high energy input. This SEM micrograph clearly shows that a lower pulse on time produces a superior surface quality.SEM images and the analysis of the machined surface morphology on the surface of the CAM7 alloy clearly showed that the machined surface of the alloy had a lower surface roughness value at a lower Ip-2A and was associated with a higher surface roughness value at a higher Ip-6A, as well as a lot of uncleared debris and blow holes.

Development of a method for measuring pulse currents of large magnitude

The paper presents the results of a study on the search for correct methods for measuring a high-value current pulse, which will be used to conduct research on the electroplastic effect. The electroplastic effect is the effect of electric current pulses on the plastic flow of metals. Electroplastic metal forming technology is a relatively new metal forming process that is energy efficient, environmentally friendly and versatile. In particular, it can be used to process metals or alloys that are difficult to process using conventional manufacturing processes. For the experimental study of the electroplastic effect, it became necessary to measure pulse currents of large magnitude, not only in amplitude, but also in the shape of the pulse. The pulsed current causes the formation of an alternating electromagnetic field near the conductors, so it can be measured with a Rogovsky current transformer. The results of the work present a schematic electrical diagram and a photograph with the appearance of an experimental installation for the study of the electroplastic effect. The results of measurements of the current value, the voltage drop on the sample and the dependence of the peak voltage values on the sample on the peak current value are shown. After making calculations and renormalising the data for the voltage drop on the sample according to the peak value of the current obtained on the transformer, the authors obtained the desired current values. The error of this method is estimated by calculating the total capacitance of capacitors, which does not exceed 2%.

Electrocatalytic performance of Shape-Controlled synthesized PdNi-rGO nano Cube on sodium borohydride and methanol electrooxidation

In recent years, increasing climate change, environmental pollution and water problems have increased the need for sustainable and environmentally friendly solutions in energy production. In this context, renewable energy sources, especially fuel cells, have become an important focus. In this study, the synthesis and characterization of the shape-controlled synthesized PdNi-rGO Cube electrocatalyst was carried out. X-ray diffraction (XRD), scanning electron microscopy with energy dispersive x-ray (SEM-EDX), and transmission electron microscope (TEM) characterization experiments were performed to examine the shape of the particles. TEM analysis revealed the formation of nanostructures with a size of 19.18 nm in the cubic structure of the PdNi-rGO. Furthermore, cyclic voltammetry (CV) measurements evaluated the usability of this electrocatalyst in the electrooxidation of sodium borohydride (NaBH4), and methanol (CH3OH). In this context, the anodic peak current density values were 77.34 mA/cm2 and 13.47 mA/cm2, for electrooxidation of sodium borohydride (NaBH4), and methanol (CH3OH), respectively. This study demonstrates that PdNi-rGO cube contains shape-controlled nanostructure, and these structures can play an important role in future renewable energy sources. It can also be considered an important step forward in the development of nanomaterial-based electrocatalysts capable of efficient energy conversion.

Innovative Fault Current Evaluation Method for Active DC Grids

DC smart grids are a promising solution for the efficient integration of renewable energy sources and loads. Still, their widespread adoption is hindered by significant challenges related to fault response, identification, and clearance. The traditional DC fault analysis method is a useful tool for straightforwardly understanding the behaviour of fault current contributions from DC converters in LVDC networks during a fault. However, when a system with multiple converters and non-negligible fault impedance need to be considered, its accuracy is severely limited due to the assumptions included in the problem solution, thus leading to the following: (a) the dependency of the results’ reliability on fault impedance values and/or other converter fault current contributions; (b) the inaccuracy of the diode current estimation; and (c) the inaccuracy of the conductor joule integral. Thus, these results’ data may be unreliable for designing protection systems for one converter or for an entire network. In order to overcome these issues, this paper proposes an innovative, simple numerical approach to DC fault current evaluation, which can be adopted when the number of converters become significant, or the network is complex. This method arises from the primary interest in solving the circuit to extract the indicators (current peak value and time, joule integral, etc.) necessary for designing circuit protections. This approach proved to grant two main advantages over traditional methods: (a) it provides accurate results, with no need to introduce any specific assumption; (b) it can be structured to manage an arbitrary number of converters; and (c) it reduces the computational processing times and resources necessary to simulate an entire DC network in comparison to other circuit solution software.

This article presents a theoretical study on the negative differential resistance (NDR) behavior of a bilaterally hydrogen-passivated Zigzag GeSe nanoribbon based single-gate field-effect transistor. It is focused on a 5-nm channel length device, and the study utilizes a simulation calculation that combines the density functional theory and non-equilibrium Green’s function. In this study, a nitrogen atom is introduced as a substitutional dopant to replace the Ge atom in the source and drain regions of the GeSe field-effect transistor to created special symmetry structure. The numerical results demonstrate that the current peak-to-valley ratio (PVR) of the device can be effectively controlled by applying a gate voltage and up to 105 with the current peak value of 0.3 nA at room temperature (300 K). The device configuration described in this study meets the requirements of real-world industrial applications. These findings highlight the potential of GeSe Zigzag nanoribbon for future electronic device applications at nanoscale.

Facile Synthesis of Fiber‐Reinforced Catalyst for High Performance Ethanol and 2‐Propanol Oxidation

In this study, Pd@TiO2 nanostructure is formed by using TiO2 fibers obtained by the electrospinning method and chemical reduction method, and this nanostructure is used in C2, and C3 alcohol oxidation studies as an application. In addition, TiO2 is compared with the Pd catalyst to investigate the effect of TiO2. In the results obtained, peak current values of 193 and 66.7 mA cm−2 for ethanol oxidation and 127.38 and 36.18 mA cm−2 for 2‐propanol oxidation are observed for Pd@TiO2 and Pd catalysts, respectively. With the addition of TiO2 to the structure, the electrocatalytic activity of C2 and C3 alcohol oxidations increases 3–3.5 times and contributes to the onset potential at an earlier potential. It also shows higher durability and stability in long‐term tests. Moreover, the addition of TiO2 to the structure enhances the electrocatalytic activity and provides high current density and long‐term stability in alcohol oxidation. These results show that fibrous structures in combination with metals improve the effect of catalysts and exhibit high potential for their application in alcohol fuel cells.
