Shanmugam,&nbsp;Seeniappan Kaliappan","doi":"10.1007/s11696-026-05186-6","DOIUrl":"10.1007/s11696-026-05186-6","url":null,"abstract":"<div><p>Biocomposite materials have gained significant attention in recent decades due to their lightweight nature, low cost, environmental sustainability, and wide range of applications in automotive, aerospace, construction, and sports industries. In this study, a novel comparative investigation was conducted on silane-treated and untreated Sesbania grandiflora stem fiber and palm oil fuel ash-derived silicon nitride (Si₃N₄) particle reinforced vinyl ester composites. The composites were fabricated using the hand lay-up technique and evaluated according to relevant ASTM standards.The results revealed that silane treatment significantly enhanced the interfacial adhesion between the reinforcement and the vinyl ester matrix, leading to improved composite performance. Among the developed composites, TC2 containing 4 vol.% Si₃N₄ exhibited the highest mechanical properties, achieving a tensile strength of 114 MPa, flexural strength of 124 MPa, and impact strength of 5.0 J. These improvements were attributed to effective stress transfer, strong fiber–matrix bonding, and uniform filler dispersion.TC3 containing 6 vol.% Si₃N₄ demonstrated superior functional performance, exhibiting a hardness of 85 Shore-D, thermal conductivity of 0.42 W/mK, and the lowest water absorption of 0.49%, corresponding to a 42.35% reduction compared with the control composite. Furthermore, TC3 showed the greatest tribological improvement, with reductions of 26.92% in specific wear rate and 27.42% in coefficient of friction. The enhanced performance was primarily associated with the synergistic effect of silane treatment and the incorporation of palm oil fuel ash-derived Si₃N₄ particles.The findings confirm the effectiveness of silane surface modification in improving the overall performance of natural fiber-reinforced vinyl ester composites. While TC2 is most suitable for applications requiring high mechanical strength, TC3 is particularly advantageous for thermal management, wear-resistant, and moisture-resistant engineering applications.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 11","pages":"13373 - 13385"},"PeriodicalIF":2.5,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149310350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review critically evaluates major classes of additives, including antioxidants, cold flow improvers (CFIs), lubricity improvers, cetane enhancers and multifunctional formulations, with main focus on their performance consistency across diverse feedstocks. Comparative analysis reveals that antioxidant additives, particularly phenolic and aminic compounds, demonstrate the most reliable improvement in oxidative stability across all feedstocks. CFIs shows strong feedstock dependence, performing most effectively in paraffinic rich diesel but they exhibit reduced efficiency in biodiesel dominant blends. Cetane enhancers consistently improve ignition quality with relatively low dosage requirements, although their impact on emissions varies with engine conditions. Lubricity improvers are found to be essential for ultra-low sulfur diesel (ULSD), where sulfur removal compromises inherent lubricity, while multifunctional additives offer synergistic benefits but they also have antagonistic interactions under certain conditions. A key contribution of this review lies in integrating performance trends with feedstock chemistry, additive concentration and operational parameters, to identify practical optimization, rather than isolated outcomes. The analysis highlight that no single additive class is universally optimal, instead tailored additive combinations are necessary to balance operability, stability and environmental performance. This work establishes an integrated framework for the rational selection and design of fuel additive systems, and also highlight the emerging directions, to expedite the development of next generation fuel additives.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 11","pages":"12615 - 12650"},"PeriodicalIF":2.5,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149309641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a quaternary graphene oxide–hydroxyapatite–zirconia–ferrocene (GO–HAp–ZrO₂–Fc) composite was developed as a bone pin material prototype using a controlled precipitation route followed by powder metallurgy processing. The composite was compacted at 400 MPa and sintered at <span>(800^{circ }hbox {C})</span> to improve densification and structural integrity. Structural and physicochemical analyses using HRTEM, SAED, XRD, FTIR, Raman spectroscopy, EDX, TGA–DSC, and BET confirmed the successful integration of GO, HAp, ZrO₂, and Fc into a stable multiphase nanocomposite with mesoporous surface characteristics and good thermal stability. Biological evaluation showed low cytotoxicity, with 91.13% cell viability at <span>(25,upmu )</span>g/mL in short-term MTT testing and 94.74% viability at <span>(20,upmu )</span>g/mL after extended cytocompatibility assessment. The composite also exhibited antibacterial activity against <i>Escherichia coli</i> and maintained cellular redox balance without inducing intracellular ROS generation in L929 fibroblast cells. Mechanical testing demonstrated a Micro-Vickers hardness of 530 HV, compressive strength of 81.2 MPa, and direct tensile strength of 92 MPa.

Intermediate Bulk Containers are widely used for packaging and shipping bulk materials. Dry refined hazardous materials are packaged inside Flexible Intermediate containers or FIBC super-sacks, which are widely used in the chemical industry for bulk handling of powders, granules, and specialty materials. These materials require packaging solutions which guarantee containment, integrity, electrostatic safety, and compliance with DOT hazardous material regulations. This paper explores progress in FIBC super-sack designs and specifications, including different fabric thicknesses, various liner materials, and UN-certified configurations for sensitive chemical compounds. A comparative examination of two specifications will help us determine potential cost savings. The project proposal is to develop the best packaging solution for hazardous chemicals. This paper studies the regulatory requirements and technical standards for UN-rated Flexible Intermediate Bulk Containers (FIBCs), commonly known as super sacks, used to transport hazardous chemicals in Packing Groups II and III. It provides an overview of classification systems, performance criteria, and compliance obligations under international and U.S. regulations (International Air Transport Association 2023; International Maritime Organization 2023). Flexible Intermediate Bulk Containers (FIBCs), commonly referred to as super sacks, are widely used for the bulk handling and transport of dry hazardous materials in the chemical industry. For substances classified under U.S. DOT regulations as Packing Group III (Class 9), UN packaging certification is required prior to shipment. This study evaluated two FIBC configurations of 190 GSM and 230 GSM woven polypropylene body fabric to determine whether the lower-specification bag meets UN certification requirements under 49 CFR Part 178, Subpart O, and whether it represents a viable cost-reducing alternative. Both configurations were U-shaped, 4-panel bags with a duffel-top inlet, a 3 mil polypropylene liner, and a safe working load of 2,500 lbs. Both the 190 GSM and 230 GSM FIBCs passed all six required PG III tests: Top Lift (178.812), Drop (178.810), Stacking (178.815), Topple (178.816), Righting (178.817), and Tear (178.818) (Pipeline and Hazardous 2022, 2025). No performance differences were observed between the two setups throughout any test. These data show that the 190 GSM bag is a suitable alternative to the 230 GSM bag for packaging hazardous chemical shipments in bulk under the tested conditions, with potential procurement cost savings for high-volume orders. Limitations encompass the single-material scope of testing and the absence of long-term storage or cyclic load assessments.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 9","pages":"10635 - 10645"},"PeriodicalIF":2.5,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148871763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The compounds were structurally and physiochemically characterized using elemental analysis, conductivity measurements, FT-IR, UV–visible, ¹H and ¹³C NMR spectroscopy, mass spectrometry, magnetic susceptibility, powder XRD, and TGA. Spectroscopic data confirmed azomethine formation and coordination through nitrogen donor atoms of both ligands.

Magnetic and electronic spectral evidence showed octahedral geometry for Co(II) and Ni(II) complexes and distorted square-planar geometry for Cu (II) complexes. From the results of XRD, Co(II)-HL₂ and Ni(II)-HL₂ complexes gave nanocrystalline character, whereas the remaining complexes are amorphous solids. DFT calculations at the level of B3LYP confirmed such geometries and revealed that HL₁ is more chemically reactive, HL₂ being more stable. Biological testing of the free ligands showed no antibacterial activity, whereas the metal complexes exhibited moderate antibacterial activity against Escherichia coli and Staphylococcus aureus. The DPPH antioxidant test revealed that the Co(II)-HL₁ complex possessed the best free radical scavenging performance (with an inhibition of 22.51%).

Most notably, it is used as the electrolyte in the FFC Cambridge process for metal/alloy production. Despite its widespread use at elevated temperatures, CaCl₂ is often treated as a chemically and structurally invariant salt, with limited consideration of its solid-state history prior to melting. This review examines how hydration history, dehydration pathways, and associated microstructural evolution govern the thermodynamic stability and functional performance of CaCl₂ across solid, liquid, and electrochemical regimes. The crystal chemistry of CaCl₂ hydrates and their stepwise dehydration behavior are summarized, with emphasis on insights from in-situ high-temperature X-ray powder diffraction that reveal the coexistence of multiple hydrated, partially dehydrated, and anhydrous phases. Particular attention is given to the existence of distinct anhydrous CaCl₂ polymorphs with different unit-cell volumes, their relative stability above 150 °C, and the role of lattice densification during dehydration. The limitations of conventional thermal analysis and the advantages of in-situ diffraction for resolving metastable intermediates and phase competition are critically discussed. Beyond the solid state, the review considers how pre-melting structural states, defects, and residual disorder may influence molten-salt structure, ionic transport, and electrochemical stability. The implications of these structure–stability relationships for molten-salt electrochemical processes are highlighted. Finally, key knowledge gaps and future research directions are identified, underscoring the need for integrated in-situ structural, thermal, and electrochemical studies to enable rational control of CaCl₂ performance in high-temperature technology applications worldwide.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 11","pages":"12755 - 12774"},"PeriodicalIF":2.5,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149309503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
