However, there is a knowledge gap in understanding the thermal stability and combustion efficiency of HEFA-derived SAF (Hydroprocessed Esters and Fatty Acids Sustainable Aviation Fuel) and its blends compared to JET A-1. This study addresses this gap by evaluating the thermal and combustion properties of pure JET A-1 (J100), HEFA-SAF (HS100), and their blends (JxHSy) using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), supported by gas chromatography-mass spectrometry (GC-MS) for compositional insights. Results indicate that HS100 exhibits superior thermal stability, with degradation occurring between 100 °C and 205 °C, compared to J100's 85 °C to 168 °C range. TGA data show that HS100 degrades more gradually, while J100 undergoes rapid mass loss, suggesting differences in chemical composition. DSC analysis revealed that HS100 has a broader and higher exothermic peak (248 °C) compared to J100 (234 °C), supporting its cleaner combustion characteristics. Blended fuel samples demonstrated intermediate stability, with J30HS70 optimizing both thermal resilience and energy efficiency. GC-MS analysis showed higher paraffinic content in HS100 (79%) compared to J100 (55%), reducing soot emissions and improving combustion efficiency. However, HS-rich blends exhibited lower ignition and comprehensive performance indices, indicating trade-offs between cleaner combustion and ignition properties. This study demonstrated enhanced thermal stability and cleaner combustion characteristics of HEFA-SAF and its blends. It advances knowledge on fuel composition-thermal behavior relationships, offering insights into how SAF blending ratios influence combustion efficiency, ignition properties, and fuel system compatibility. By demonstrating that specific blends (<em>e.g.</em>, J30HS70) optimize both thermal resilience and energy efficiency, this research contributes to refining fuel standards (ASTM D7566) and shaping SAF adoption strategies for commercial aviation.</p>","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 8","pages":" 2159-2174"},"PeriodicalIF":5.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, surface and grain boundary defects in CsPbI<small>₂</small>Br contribute to significant non-radiative recombination and energy loss, while the energy level mismatch between the carbon electrode and CsPbI<small>₂</small>Br exacerbates open-circuit voltage (<em>V</em><small>_oc</small>) loss, limiting photovoltaic performance. To address these challenges, 3-(trifluoromethyl)phenylthiourea (3-TPT) and 4-(trifluoromethyl)phenylthiourea (4-TPT) were introduced as interfacial modifiers. The functional groups in 3-TPT and 4-TPT, including C<img>S, –CF<small>₃</small>, and –NH<small>₂</small>, effectively passivated cationic and anionic defects, reducing defect density and suppressing non-radiative recombination. Additionally, isopropyl alcohol (IPA) solutions of 3-TPT and 4-TPT promoted secondary crystallization and grain reorganization, resulting in larger grains and denser boundaries, which significantly enhanced the CsPbI<small>₂</small>Br crystal quality. Furthermore, 3-TPT and 4-TPT modulated the band structure of CsPbI<small>₂</small>Br, improving the energy level alignment with the carbon electrode and minimizing energy loss. The power conversion efficiencies (PCEs) of C-PSCs modified with 3-TPT and 4-TPT reached 13.78% and 14.15%, respectively, compared to 12.18% for the unmodified device.

However, these batteries are not without their limitations and face various degradation mechanisms that can impact their performance and safety. As the demand for more reliable and efficient batteries grows, it becomes crucial to understand these degradation mechanisms and develop strategies for improving the design and operation of LIBs. Therefore, degradation mechanisms have to be investigated to improve and re-design the commercial devices with the goal of enhancing their capacity, improving their safety and performances. Subsequently, the basic of understanding on the mechanisms involved in the degradation throughout the cycling life of LIBs became a crucial focal point for the research. &lt;em&gt;In situ&lt;/em&gt;/&lt;em&gt;operando&lt;/em&gt; studies are experiments that involve monitoring the behaviour of a system under realistic operating conditions. This analysis can provide valuable insights on the aging and degradation process on the battery materials and devices. In this work, fast &lt;em&gt;in situ&lt;/em&gt;/&lt;em&gt;operando&lt;/em&gt; X-ray diffraction computed tomography experiments have been conducted on MJ1-18650 commercial cells during non-stop high C-rate cycling. The goal was to map the changes occurring in the negative electrode of an aged cell during cycling by comparing the phase transitions and lithiation distribution of electrodes in an aged cell to those in a pristine cell. Moreover, comparisons between low and high C-rates were analysed to better understand the influence of the chosen current rate on lithiation distribution inside the cell. During the experiment, the pristine cell showed a uniform phase transition across the volume, with a homogeneous lithiation distribution for both electrodes in charged and discharged states. The aged cell showed a high degree of degradation and deformation after 1200 charge/discharge cycles, with a considerable capacity loss of 14.5%. During the experiment, the aged cell showed an inhomogeneous distribution of lithiation states at both charged and discharged states. The phase transition within the electrode was affected by the rate at which current was delivered to the cell, and it was discovered that at high rates, there were many lithiation states coexisting rather than the phase transition being uniform across the volume. High discharge rates have an impact on graphite phase transitions from the cell's initial condition. The cell was considerably more impacted by current rates after ageing, exhibiting a more marked co-existence of lithiation stage across the volume. The deterioration of the cell certainly had an effect on the phase transition: the divergent dynamics between the centre of the cell and the outside body were more pronounced than in the pristine cell, and the aged cell was unable to attain a fully delithiated or lithiated st","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 7","pages":" 1848-1858"},"PeriodicalIF":5.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/se/d4se00358f?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
