Despite the limited exploration of electrochemical sensors utilizing SA, their integration into sensing electrodes holds great promise for improving the sensitivity and selectivity of bioactive molecule detection. In this study, SA modified electrodes were developed by anchoring transition metal atoms (Fe, Co, or Cu) onto nitrogen-doped graphene (N–C) via M–N–C coordination, synthesized through a ball milling–pyrolysis method. Electrochemical impedance spectroscopy measurements demonstrated a significant reduction in electrochemical impedance for Fe, Co, and Cu SA electrodes, indicating an enhanced electron transfer rate at the sensor interface. To evaluate the electrochemical sensing performance of SA-modified electrodes, dopamine (DA) and hydrogen peroxide (H₂O₂)—two biologically important molecules—were selected as representative analytes. Chronoamperometry revealed that Fe SA exhibited an enhanced sensitivity toward DA, reaching 0.02 A/µM, attributed to the unique electronic structure and catalytic properties of Fe sites, whereas Co SA and Cu SA did not show a notable improvement in DA detection sensitivity compared to the N–C electrode (0.01 A/µM). In contrast, Fe, Co, and Cu SA electrodes demonstrated improved sensitivity for H₂O₂ detection, achieving 0.35, 0.28, and 0.35 A/mM, respectively, surpassing the performance of the N–C electrode (0.076 A/mM). Density functional theory calculations of DA oxidation kinetics demonstrated that Fe–N site facilitated the adsorption and conversion of OH, thereby improving electrochemical response. These findings highlight the potential of SA as an effective electrode modification strategy for advancing electrochemical sensing technologies and enabling highly sensitive biomolecular detection.</p></div>","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the management of their carbon emissions has become particularly important. To track the carbon emission status of various carbon emission sources in large substations, this paper takes a typical 500 kV substation as an example and establishes an evaluation model for the full life cycle carbon emissions of the substation. The research shows that there are obvious differences in the characteristics of carbon emission sources in each stage of the full life cycle of substation projects. In the equipment manufacturing stage, a large amount of carbon emissions are generated due to the input of materials and energy, among which SF₆ gas plays a dominant role. In the decommissioning stage, however, the recycling of materials such as SF₆ generates a large amount of negative carbon emissions. Improving the recycling efficiency of materials like SF₆ can effectively reduce carbon emissions. The proportion of actually consumed SF₆ during the operation and maintenance stage in the full life cycle is the highest, reaching 52.4%. Scientifically managing and monitoring SF₆ gas and reducing its leakage rate will help significantly reduce the full life cycle carbon emissions of substation projects. Actively addressing global climate challenges is the responsibility of a major country. The construction of the carbon emission accounting model for substation projects provides a theoretical basis for the country to formulate scientific and reasonable emission reduction targets and policies, and promotes the transformation of power enterprises towards clean energy and the improvement of energy utilization efficiency.</p>","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the bicontinuous nano-heterostructure consisting of ultrathin Ni₄N/Ni₃N particles on hollow tubular carbon fibers was fabricated, and it exhibits superior catalytic activity with a very low overpotential of 75 mV@10 mA cm⁻² for HER and stable performance for over 50 h. Theoretical calculation results revealed that the built-in interfacial electric field (BIEF) is formed due to the distinct lattice arrangements and uneven charge distribution in biphasic metal nitrides. The BIEF promotes the electron localization around the interface and enables high valence Ni and more exposed binding sites on the surface of Ni₄N/Ni₃N/NiO/CFs to accelerate the HER. Meanwhile, the pore connectivity effects facilitate the full exposure of the optimized Ni₄N/Ni₃N heterointerface, which possesses enhanced intrinsic catalytic activity as active sites. Moreover, the pore connectivity microstructure of the Ni₄N/Ni₃N/NiO/CFs is conceptualized and verified through the utilization of three-dimensional tomograph reconstruction technology.

In this perspective, we categorize recycling approaches for nickel manganese cobalt (NMC) cathodes and assess their advantages and limitations for practical commercialization. We argue that the successful integration of recycled materials into precursor cathode production critically depends on overcoming challenges related to impurity control, energy efficiency, and structural stability of recycled materials.

Aberration-corrected scanning transmission electron microscopy (STEM) directly demonstrates distinct zinc vacancies (V_Zn), which is also confirmed by electron spin resonance analysis. The results of experiments and density functional theory (DFT) calculations manifest that Er/La-doping not only promotes the formation of V_Zn but also enhances the built-in electric field, thus facilitating the rapid transfer of carriers. In addition, femtosecond transient absorption spectroscopy (fs-TAS) reveals that V_Zn induces a supplementary charge transfer pathway, thereby enhancing charge separation efficiency.
