1. Electrochemical and Spectroscopic Studies of Zinc Oxide in an Eco-Friendly Deep Eutectic Solvent for Zn Electrodeposition.
PMID:日期:2025-05-01Zinc oxide (ZnO) is a waste produced from end-of-life Zinc-air batteries. Recycling of these spent batteries is important to reduce the pressure on primary zinc sources and to mitigate environmental pollution. To address the recyclability of waste ZnO from different sources, here we have studied ZnO dissolution and Zn electrodeposition in deep eutectic solvents (DES) of betaine hydrochloride (Betaine-HCl) and formic acid (FA) using spectroscopic and electrochemical techniques. Additionally, the effect of water in the DES on the dissolution of ZnO and its electrochemical and spectroscopic behaviour was also studied. Solubility of ZnO in DES was found to be 95 g l which decreased slightly to 85 g l in the DES containing 10% water. Fourier transform infrared and Raman studies revealed that ZnO dissolved in DES by forming a [ZnClFA] complex. Electrochemical studies showed that Zn deposit morphology and structure varied with water content in the DES. A uniform Zn deposit was achieved in ZnO-DES mixture whereas the presence of water gave a porous morphology. Thus, this study revealed an easy and eco-friendly route to recycle ZnO.

2. Electrochemical HOCl Production Modeling for an Electrochemical Catheter.
PMID:日期:2024-11-01Hypochlorous acid (HOCl) is a strong oxidizing agent that damages cells by interacting with lipids, nucleic acids, sulfur-containing amino acids, and membrane components. It is an endogenous substance produced by the immune system to protect mammals from pathogens. Previously, we developed an HOCl-generating electrochemical catheter (e-catheter) and demonstrated its ability to prevent central line-associated bloodstream infections. The e-catheter is an electrochemical system consisting of two parts - an e-hub and a tube. Working, counter, and reference electrodes are placed in the e-hub, which contains 0.9% NaCl as an electrolyte. Although a prototype of this device has shown activity against pathogens, it is helpful to understand the factors influencing associated electrochemical/chemical processes to optimize design and efficacy. A mathematical model could predict factors influencing HOCl generation and distribution in the catheter and could aid in optimizing these devices. Here, we developed an Electrochemical Hypochlorous Acid Production (EHAP) model to predict factors influencing electrochemical generation and distribution of HOCl in e-catheters, including polarization time, diffusion of HOCl into the e-catheter, operational voltage, working electrode length, and surface area.

3. Electrochemical Screening and DFT Analysis of Acetylacetonate Metal Complexes in Organic Solvents.
PMID:日期:2024-10-15Seven acetylacetonate (acac) metal complexes ranging from early transition metals to post-transition metals were examined by cyclic voltammetry in acetonitrile (MeCN), dichloromethane (DCM), tetrahydrofuran (THF), dimethyl sulfoxide (DMSO), and dimethylformamide (DMF). The electronic potential of any observed redox events is reported along with an analysis of the reversibility of those events across a range of scan rates. Group 8 compounds Fe(acac) Ru(acac) showed at least quasi-reversible reductions across all solvents while Ru(acac) also featured a reversible oxidation. The early and post-transition compounds VO(acac), Ga(acac) and In(acac) exhibited irreversible reductions, while TiO(acac) showed no redox activity within the examined potential ranges. Mn(acac) featured an oxidation that showed solvent-dependent reversibility, and a reduction that was irreversible in all examined solvents. DFT calculations indicated minimal solvent effects on the HOMO-LUMO gap for the majority of compounds, but a significant effect was observed for Ru(acac). This study serves as a valuable initial step for further examination of acetylacetonate metal complexes for applications as electrochemical internal standards, nanoparticle precursors, and electrocatalysts.

4. Screen-Printed Sensors Modified with Nafion and Mesoporous Carbon for Electrochemical Detection of Lead in Blood.
PMID:日期:2024-02-01Lead (Pb) has long been acknowledged as a systemic toxicant, with pronounced health impacts observed even at low exposure levels, particularly in children. Adverse effects include diminished cognitive function, altered behavior, and developmental delays. Consequently, it is imperative to conduct regular monitoring of Blood Lead Levels (BLLs). In this work, we report on an electrochemical sensor based on screen-printed carbon electrode (SPCE) coated with Nafion and mesoporous carbon (MC). The sensor system uses simple sample preparation (acidification and dilution of whole blood), minimal sample volume (a few blood drops, 200 l), and swift time-to-results (1 h). A limit of quantitation (LOQ) of 0.3 g dL Pb was achieved in whole blood. To demonstrate the practical utility of our sensor system, we evaluated its performance in the analysis of blood samples collected from children (n = 25). Comparative analysis with the laboratory-based gold standard method of inductively coupled plasma mass spectrometry (ICP-MS) demonstrated approximately 77% accuracy and 94% precision. We anticipate that our approach will serve as a valuable tool for more frequent BLL monitoring, particularly in communities where access to laboratory testing is impractical or expensive.

5. Characterization of Factors Affecting Stripping Voltammetry on Thermoplastic Electrodes.
PMID:日期:2023-09-27Thermoplastic carbon electrodes (TPEs) are an alternative form of carbon composite electrodes that have shown excellent electrochemical performance with applications in biological sensing. However, little has been done to apply TPEs to environmental sensing, specifically heavy metal analysis. The work here focuses on lead analysis and based on their electrochemical properties, TPEs are expected to outperform other carbon composite materials; however, despite testing multiple formulations, TPEs showed inferior performance. Detailed electrode characterization was conducted to examine the cause for poor lead sensing behavior. X-Ray photoelectron spectroscopy (XPS) was used to analyze the surface functional groups, indicating that acidic and alkaline functional groups impact lead electrodeposition. Further, scanning electron microscopy (SEM) and electrochemical characterization demonstrated that both the binder and graphite can influence the surface morphology, electroactive area, and electron kinetics.

6. Ionic Liquids Containing the Sulfonyl Fluoride Moiety: Integrating Chemical Biology with Materials Design.
PMID:日期:2023-06-23The persistent achievements of ionic liquids in various fields, including medicine and energy necessitate the efficient development of novel functional ionic liquids that exhibit favorable characteristics, alongside the development of practical and scalable synthetic methodologies. Ionic liquids are fundamentally understood as materials in which structure begets function, and the function and applicability of ILs is of utmost concern. It was recently reported that "full fluorosulfonyl" electrolyte is compatible with both the Li metal anode and the metal-oxide cathode that is crucial for the development of high-voltage rechargeable lithium-metal batteries. Inspired by these results, for the first time, we reported the synthesis of a series of ionic liquids with a sulfonyl fluoride motif using an highly effective and modular fluorosulfonylethylation procedure. Herein, we present a detailed analysis of novel sulfonyl fluoride-based ionic liquids paired with the hexafluorophosphate anion. We employed a combination of computational modeling and X-ray crystallographic studies to gain an in-depth understanding of their structure-property correlations.

7. Scanning Ion Conductance Microscopy of Nafion-Modified Nanopores.
PMID:日期:2023-06-21Single nanopores in silicon nitride membranes are asymmetrically modified with Nafion and investigated with scanning ion conductance microscopy, where Nafion alters local ion concentrations at the nanopore. Effects of applied transmembrane potentials on local ion concentrations are examined, with the Nafion film providing a reservoir of cations in close proximity to the nanopore. Fluidic diodes based on ion concentration polarization are observed in the current-voltage response of the nanopore and in approach curves of SICM nanopipette in the vicinity of the nanopore. Experimental results are supported with finite element method simulations that detail ion depletion and enrichment of the nanopore/Nafion/nanopipette environment.

8. {"_":"Polymer-Regulated Electrochemical Reduction of CO on Ag.","sub":["2"]}
PMID:日期:2023The influence of polymer overlayers on the catalytic activity of Ag for electrochemical CO reduction to CO is explored. Polystyrene and poly(4-vinylpyridine) films of varying thicknesses are applied as catalysis-directing overlayers atop Ag electrodes. For polystyrene, substantial suppression of CO reduction activity is observed while the hydrogen evolution reaction (HER) increases. The addition of a nitrogen heteroatom into the phenyl groups of polystyrene (e.g., a pyridine ring) results in an increase in the conversion of CO to CO and suppression of HER. Block copolymer variants containing both phenyl and pyridyl functionalities exhibit similar activity for CO evolution but appear to suppress HER further than the polymer layer containing only pyridine groups. The size of the blocks for the copolymer influences the catalytic output of the Ag electrode, suggesting that the hierarchical structure that forms in the block copolymer layer plays a role in catalytic activity at the electrode surface. Analysis of the polymer overlayers suggests that polystyrene significantly inhibits all ion transport to the metal electrode, while poly(4-vinylpyridine) enables CO transport while modifying the electronics of the Ag active site. Therefore, the engineered application of polymer overlayers, especially those containing heteroatoms, enables new avenues of electrochemical CO reduction to be explored.

9. Electrochemical Determination of Manganese in Whole Blood with Indium Tin Oxide Electrode.
PMID:日期:2022-05-11In this work, we demonstrate accurate and precise measurement of manganese (Mn) concentration in human whole blood with indium tin oxide (ITO) electrode using square wave stripping voltammetry. While an essential trace metal for human health, elevated levels of Mn due to environmental or occupational exposure have been associated with severe neuromotor dysfunction characterized by parkinsonism and cognitive dysfunction making the monitoring of Mn in whole blood necessary. Pediatric populations are particularly susceptible to Mn given their developing brain and potential long-term impacts on neurodevelopment. The current gold standard for whole blood Mn measurements is by ICP-MS, which is costly and time consuming. The electrochemical detection with ITO working electrode in this work showed a limit of detection of 0.5 μg l and a linear range of 5 to 500 μg l, which encompasses the physiological Mn levels in human whole blood (5-18 μg l). Our results of Mn measurement in whole blood show an average precision of 96.5% and an average accuracy of 90.3% compared to ICP-MS for both the normal range (5-18 μg l) and the elevated levels (>36 μg l) that require medical intervention. These results demonstrate the feasibility of Mn measurements in human blood with electrochemical sensors.

10. {"_":"Translocation Behaviors of Synthetic Polyelectrolytes through Alpha-Hemolysin (α-HL) and Porin A (MspA) Nanopores.","i":["Mycobacterium smegmatis"]}
PMID:日期:2022-05-11DNAs have been used as probes for nanopore sensing of noncharged biomacromolecules due to its negative phosphate backbone. Inspired by this, we explored the potential of diblock synthetic polyelectrolytes as more flexible and inexpensive nanopore sensing probes by investigating translocation behaviors of PEO-b-PSS and PEO-b-PVBTMA through commonly used alpha-hemolysin (α-HL) and porin A (MspA) nanopores. Translocation recordings in different configurations of pore orientation and testing voltage indicated efficient PEO-b-PSS translocations through α-HL and PEO-b-PVBTMA translocations through MspA. This work provides insight into synthetic polyelectrolyte-based probes to expand probe selection and flexibility for nanopore sensing.
