Organic waste is one of the most diverse, abundant, and persistent types of pollutants, creating an urgent need for green and effective remediation strategies. Among various approaches, electrochemistry offers a unique opportunity, providing a flexible, scalable, efficient, and reagent-free method. Moreover, there is a strong correlation between the mechanistic understanding of organic waste degradation at the molecular level and the efficiency of the overall remediation process. Herein, we discuss major methods for remediating various types of halogenated organic waste and polymers, briefly explore the mechanistic insights behind each approach, and highlight key challenges and opportunities from a practical perspective.

This review describes a four-dimensional (4D) impedance analysis approach for analyzing the oxide film formation process that accompanies the dissolution of metals and alloys. In this analysis, the measured impedance was plotted on a three-dimensional (3D) complex impedance plot composed of real, imaginary, and time axes. Since the impedance plots of the same frequency in each spectrum are smoothly connected using a spline under tension function, the instantaneous impedance can be determined at an arbitrary time on the 3D complex impedance plot. In this review, the application of 4D impedance analysis to an additively manufactured aluminum alloy produced by a laser powder bed fusion process is introduced as a representative additive manufacturing technology. Additionally, the corrosion resistance mechanisms are discussed based on the impedance variation, which is attributed to dissolution and oxide film formation to generate a unique alloy structure.

The growing demand for food quality, safety and sustainability is driving the adoption of cost-effective real-time monitoring systems across the agricultural and food chain. This review critically examines the status of electrochemical biosensors for monitoring key agri-food targets including bacteria and foodborne contaminants, nutritional components, pesticide residues, soil nutrients, fertilizers and environmental pollutants, and their potential to address global food challenges. Following an overview of sensor types, target analytes, detection mechanisms and performance metrics, we discuss key barriers to field deployment such as stability, matrix interference, calibration, standardization and user acceptance. Proposed solutions such as integration with mobile platforms, data analytics and intuitive interfaces are outlined as potential pathways to accelerate adoption. With further development, electrochemical biosensors have the potential to become powerful tools in data-driven decision support systems, enabling precision agriculture, risk assessment and improved food quality.

The electrochemical reduction of carbon dioxide (CO2RR) to valuable multi-carbon (C2+) products presents a promising strategy for sustainable fuel and chemical production. Copper (Cu)-based catalysts are particularly suited for C–C bond formation thanks to their unique interaction with key CO2RR intermediates. Recent advancements in catalyst design, including surface engineering, molecular coating, doping and alloying, and tandem catalysis, have significantly improved C2+ product selectivity at the laboratory scale. However, translating these improvements to large-area electrodes remains a critical challenge due to difficulties in catalyst synthesis, structural stability, and fabrication techniques. This review explores the latest progress in Cu-based CO2RR catalysts, highlights the barriers to scaling up synthesis and electrode fabrication, and proposes potential solutions inspired by established industrial technologies. Addressing these challenges could bring CO2RR closer to commercial viability, enabling the large-scale production of sustainable carbon-based fuels and chemicals.

This review underscores the growing relevance of impedance spectroscopy (IS) in neuromorphic research and its capacity to advance brain-inspired computation. Neuromorphic systems, which emulate biological neural networks, provide compact, adaptive, and energy-efficient solutions for edge applications such as robotics, wearable health monitoring, and environmental sensing. Since early studies on electrochemical oscillators, IS has been pivotal in probing neuron-like dynamics. Frequency-domain analysis of artificial synapses yields essential insights into synaptic plasticity—the core mechanism of learning and memory—shaped by functions like retention and filtering. Memristor-based synapses display chemical inductor behavior, evident as a negative arc in impedance spectra, highlighting their complex dynamics. More broadly, IS is increasingly positioned not only as a diagnostic tool for material performance but also as a framework for designing systems governed by ion migration, accumulation, and relaxation. By capturing these processes, IS provides a powerful perspective for analyzing and engineering physical computation components.

Porous electrodes are important in practical applications of electrochemistry. Single cylindrical pore models are first presented. In the presence of direct current (DC) DC potential and DC concentration gradients appear. These gradients are related to each other. Analytical solutions exist only in the absence of the DC potential gradient. When a concentration gradient is present, two semicircles appear on the complex plane plots. Solution resistivity in pores causes formation of the high frequency line at 45° on the complex plane plots.
However, the real pores are multidimensional containing macro, meso, and micro pores. Many models of inhomogeneous porosity were developed. Further models used Poisson–Nernst–Planck theory to include charge interactions. In very narrow pores, double layers of the pore walls overlap. Future challenge is to obtain pore parameters from the impedance measurements of complex systems.

Real-time, continuous in vivo molecular monitoring is crucial for advancing biomedical research and clinical healthcare, yet traditional methods face significant limitations. Electrochemical DNA-based (eDNA) biosensors are emerging as a powerful and highly versatile platform to address these needs. This review highlights key advancements within the last three years in eDNA biosensors tailored for in vivo continuous monitoring, emphasizing strategies to overcome challenges in stability, selectivity, and reversibility. Specifically, we delve into core eDNA biosensor designs and their in vivo applications, such as therapeutic drug monitoring, pharmacokinetic studies, real-time tracking of disease and neurochemical biomarkers, and feedback-controlled drug delivery. Furthermore, we critically examine significant progress in developing calibration-free operational strategies and ongoing efforts to tackle challenges related to long-term stability, receptor responsiveness, and target selectivity. The continued evolution of these platforms and their integration with artificial intelligence, positions eDNA biosensors as transformative tools for future biomedical breakthroughs and precision healthcare.
