This study aimed to design the poly (acrylamide-maleic anhydride-POSS)/(FA &amp; TPGS) nanocarrier (P(AAm-MA-POSS)/(FA &amp; TPGS) NC) as a GSH-sensitive and folic acid (FA)-modified targeted drug delivery system. For this purpose, the P(AAm-MA-POSS)/(FA &amp; TPGS) copolymer was synthesized via free radical polymerization of AAm, MA, and POSS-glycidyl methacrylate (POSS-GMA) monomers, followed by chemical grafting of FA-NH₂ and TPGS-SS-NH₂. Finally, the synthesized copolymer was self-assembled into the P(AAm-MA-POSS)/(FA &amp; TPGS) nanocarrier with a hydrophobic POSS-based core surrounded by the hydrophilic TPGS and FA moieties. Sorafenib tosylate (ST) drug was encapsulated during the nanocarrier preparation. The TEM and DLS results confirmed the successful preparation of a self-assembled nanocarrier with around 100 nm diameter. The prepared nanocarrier exhibited enhanced cellular uptake through FA receptor-mediated endocytosis and GSH-sensitive drug release owing to the disulfide bond cleavage in the presence of reductive GSH. The efficiency of prepared ST-loaded nanocarrier against MCF-7 cancer cells was verified by MTT, and decreased amounts of the IC₅₀ for this ST-loaded nanocarrier compared to pure ST exhibited higher cytotoxicity of the drug-loaded nanocarrier. Thus, the developed targeted nanocarrier can be a suitable choice for inhibiting cancer cells.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 10","pages":"12073 - 12091"},"PeriodicalIF":2.5,"publicationDate":"2026-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007451","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}

Its quantity and quality depend on several parameters; a few important ones are the type of biomass, reaction temperature, and time. In this study, effects of temperature and reaction time on pyrolysis of <i>Erythrina indica</i> (EI) biomass were examined in a tubular reactor at temperatures of 400–700 °C and reaction times of 60–120 min. The resulting pyrolytic products, especially biochar, underwent a comprehensive characterization employing advanced analytical techniques. The results revealed a clear dependence of product yield and quality on pyrolysis temperature and reaction duration. The surface morphology of fibrous lignocellulosic biomass transformed from compact to a porous biochar structure during pyrolysis. The experimental BET analysis showed that maximum surface area (250.76 m²/g) biochar obtained at 500 °C for 60 min, while XRD indicated partial graphitization at higher pyrolysis temperatures. The bio-oil exhibited acidic characteristics (pH = 3.2–4.4) and a maximum HHV is obtained at 500 °C for 90 min.

In this study, the effects of nanofluid over two different reactor geometries on liquid–liquid flow for mass transfer applications have been systematically investigated using a model system, toluene–acetic acid–water. Three different aqueous-phase nanofluids based on (i) metallic nanoparticles (Ni NP) of 60 nm particle size, (ii) metalloid oxide nanoparticles (SiO₂ NP) of 22 nm particle size, and (iii) carbon nanoparticles (CNPs) of 80 nm particle size have been synthesized to enhance interfacial transport. Further, to elucidate the effect of reactor geometry on mass transfer, a comparative study was conducted using both a straight tube and a coiled flow inverter (CFI) reactor at a constant inlet toluene velocity while varying the aqueous-phase velocity. The results reveal that nanofluid in CFI geometry significantly improve the overall volumetric mass transfer coefficient (kₒᵥₐ). Among the tested systems, SiO₂ nanofluids in the CFI configuration delivered the highest enhancement, achieving up to a threefold increase compared to straight tubes. Flow mapping analysis resolves that nanoparticle-assisted CFIs promote stable slug flow, leading to enhanced interfacial renewal and reduced mass transfer resistance leading to energy sustainability. The observed enhancements arise from the increased interfacial area resulting from the dispersion of nanoparticles, along with enhanced mixing induced by geometry-driven secondary flows. This study demonstrates that nanofluid-assisted coiled flow inverters represent a promising and scalable platform for process intensification for separation processes.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 10","pages":"11805 - 11816"},"PeriodicalIF":2.5,"publicationDate":"2026-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007361","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 objective is to evaluate the effect of bottom ash incorporation on geopolymerization behavior through kinetic modeling and material characterization. Experimental investigations were conducted using X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, and compressive strength testing under curing temperatures of 30–90 °C. The geopolymerization kinetics were analyzed using an iso-conversional approach, and multiple solid-state reaction models were evaluated. The results demonstrate that the third-order reaction model provides the best fit to the experimental data, as indicated by the highest correlation coefficients across different compositions and curing conditions. The incorporation of bottom ash reduces the reaction rate due to its lower reactivity and higher crystallinity, as confirmed by XRD analysis. However, an optimal composition of 25% bottom ash (75:25 ratio) achieves a compressive strength of up to 41 MPa at 90 °C, indicating a favorable balance between kinetics and mechanical performance. Furthermore, the FTIR-derived correlation parameter (Corr value) shows strong agreement with compressive strength evolution, confirming its applicability as a semi-quantitative indicator of geopolymerization. These findings highlight the potential of integrating bottom ash into fly ash-based geopolymers to enhance sustainability while maintaining adequate mechanical performance. The study also demonstrates that iso-conversional kinetic modeling provides a robust framework for understanding and optimizing geopolymerization processes.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"80 10","pages":"11875 - 11889"},"PeriodicalIF":2.5,"publicationDate":"2026-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149007427","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}
