Replacing OER/CER with thermodynamically more favorable anodic reactions presents a promising strategy for reducing energy consumption and overcoming chlorine-based toxic products. This study reports a hybrid seawater electrolysis system that couples the ethanol oxidation reaction (EOR) with the hydrogen evolution reaction (HER), enabling the co-production of green hydrogen and value-added potassium acetate in alkaline seawater. Utilizing bimetallic NiCu hierarchical nanostructures supported on nickel foam (NiCu–HNS@NF) as a bifunctional electrocatalyst, this promising system required 220 mV less potential for EOR compared to OER to achieve a current density of 20 mA cm<small>⁻²</small>. Meanwhile, the HER required a low overpotential of only 97 mV to attain the same current density, with a faradaic efficiency (FE) of 97.6%. The CO<small>₂</small>-free selective conversion of ethanol into acetate, along with the high faradaic efficiency (FE) for H<small>₂</small>, may be attributed to the bubbles-templated interconnected hierarchical nanostructures and the bimetallic synergistic effect.

These microfluidic components require significant external energy to apply external forces. Hence, the lack of reliable and sustainable power sources impedes the widespread adoption of these devices. Since the 1970s, photobatteries have been the subject of scientific inquiry with a resurgence in recent years, catalysing the creation of diverse photobattery designs. Among these, paper-based systems have emerged as a particularly promising avenue, offering a potential solution to mitigate the environmental footprint of disposable energy storage devices. Their performance and longevity, however, are heavily dependent on the photoactive battery electrode materials and architectures employed. This comprehensive review article examines the cutting-edge research on bifunctional nanomaterials optimally suited for paper-based lithium-ion photobatteries. The focus is primarily on two-electrode configurations where a single electrode integrates both light harvesting and energy storage capabilities. Such a design is particularly advantageous for electrochemical point-of-care (POC) medical sensors, offering a compact and efficient energy solution. The work highlights the unique requirements and challenges associated with these systems and provides a comprehensive overview of potential photoactive materials. It critically evaluates their performance metrics, such as specific energy, power density, safety, and environmental impact, in the context of solar-powered POC medical sensor applications. Successful case studies and real-world applications are discussed, showcasing their potential to improve healthcare accessibility and quality, particularly in underserved and resource-constrained communities.

This study presents a comprehensive Life Cycle Assessment (LCA) of a chemolithotrophic bacterial platform for simultaneous CO<small>₂</small> mitigation and biodiesel production using <em>Bacillus cereus</em> SSLMC2 cultivated in 10 and 20 L bubble column bioreactors. Unlike phototrophic systems, this process leverages light-independent bacterial metabolism, offering year-round operation, high biomass yield, and compatibility with flue gas as a carbon source. Experimental data were integrated with LCA modeling using Umberto NXT Universal software and the ReCiPe 2016 and CML baseline methods to quantify environmental impacts across cultivation, biomass harvesting, lipid extraction, and transesterification stages. The results identify dewatering and homogenization as major environmental hotspots, contributing significantly to climate change, fossil depletion, and human toxicity categories. Endpoint analysis revealed human health and resource availability as the most impacted areas, primarily due to electricity use and chemical inputs. Cumulative energy demand assessments confirmed that scale-up from 10 to 20 L does not proportionally increase energy use, suggesting promising scalability. Recommendations include replacing centrifugation with membrane-based dewatering, solvent recovery systems, integration of renewable energy, and recycling of CO<small>₂</small> and water. This is the first LCA study to evaluate chemolithotrophic CO<small>₂</small> bio-mitigation coupled with biodiesel production at pilot scale using empirical data.

Herein, 18-crown-6 and fluoroethylene carbonate (FEC) were introduced as combined additives to improve the stability of the electrode/electrolyte interface and enhance long-term cycling performance. The presence of FEC promotes the formation of a LiF-rich solid electrolyte interphase (SEI), which guides lithium deposition and accelerates the transport of Li<small>⁺</small> ions. Additionally, 18-crown-6 can eliminate “hotspots” during the lithium deposition and dissolution processes, leading to superior electrochemical performance.
