CFD modelling coupled with the Reynolds stress model was employed to analyze hydrodynamics, turbulence characteristics and mixing process in TC reactors equipped with these novel cylinders, alongside a classical smooth cylinder for baseline comparison. Simulation results show the corrugated surfaces significantly affect Taylor vortex dynamic, NZ20 exerts the strongest influence on velocity fields, while NZ80 shows the weakest effect, with its flow field closely resembling that of a smooth cylinder. All novel cylinders generate higher flow strain rates compared to the smooth cylinder (e.g., NZ20 achieves a ∼40 % increase), while improving strain rate uniformity (reducing the coefficient of variance by 10–15 %). NZ20 further outperforms others by exhibiting the highest turbulent kinetic energy dissipation rate (∼60% higher than the smooth cylinder), effectively reducing micro-mixing time. At Reynolds number exceeding 1249, NZ20 and NZ40 display steeper concentration-response curves and achieve 10–25% shorter macro-mixing times than NZ80 and the smooth cylinder. This discrepancy arises from the enhanced axial flow induced by their larger corrugation wavelengths; in contrast, NZ80 and the smooth cylinder show comparable mixing times due to NZ80’s high roughness density mitigating such effects. To facilitate practical applications, an empirical correlation for predicting macro-mixing time in TC reactors with various rotating cylinders has been developed. These findings provide critical insights for optimizing TC reactor performance through purposeful surface modification strategies.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"25 ","pages":"Article 100976"},"PeriodicalIF":7.1,"publicationDate":"2025-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145748329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, released from industrial and hospital effluents, FLT is not fully removed by conventional water treatments, resulting in contamination of water sources that threatens aquatic ecosystems and thus human health. Therefore, there has been a pressing need for sensitive and reliable FLT monitoring, but existing techniques are often costly, labor-intensive, and complex, limiting their practicality. To address this challenge, herein we report the novel design of electrochemical sensor based on a new class of electrode modifier, ZS-CN nanocomposite, synthesized by integrating zirconium (Zr)-doped SnO₂ nanoparticles (ZS) onto 2D graphitic carbon nitride nanosheets (CN). Especially, we introduce Zr as a new dopant in SnO₂ and reveal that the correlative coupling of ZS with porous CN allows for their intimate interfacial contact that promotes efficient electron transfer and electrocatalytic activity, while keeping the functional groups of both components active. As a result, the electrochemical sensor designed by the ZS-CN nanocomposite coated glassy carbon electrode demonstrates an outstanding level of selectivity and sensitivity (1.6553 µA µM⁻¹ cm⁻²) for FLT with a low detection limit (0.009 µM) and a wide detection linear range (0.04–1166 µM), alongside robust reproducibility, stability, and applicability in real-world samples (e.g., human urine and river water). Furthermore, its cyclic voltammetric responses provide mechanistic insights into the correlation between multi-electron redox process and FLT transformation pathways, informing future interfacial engineering strategies for designing versatile electrochemical systems for pharmaceutical pollutant monitoring.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"25 ","pages":"Article 100981"},"PeriodicalIF":7.1,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145691920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recycled zeolites were characterized by NMR-MAS, FT-IR, XRD, SEM, EDX-mapping and TGA/DSC analysis. XRD analysis after adsorption showed that the peak intensity decreased due to the presence of adsorbed ions on the zeolite surface. NMR-MAS revealed the chemical shift of ²⁹Si and ²⁷Al after adsorption due to the presence of Co and Ni in the samples, which tend to affect the chemical environment of the orbital spin. The maximum capacities (Q_m,_exp) obtained were ∼780, ∼600, ∼1000 and ∼1300 mg/g for Sr²⁺, In³⁺, Ni²⁺ and Co²⁺, respectively. The Langmuir isotherm provided the most accurate non-linear fit to the experimental data, with an R² &gt; 0.993, indicating that the metal ions undergo homogeneous monolayer adsorption on the adsorbent surface. The Freundlich isotherm showed the presence of multilayer adsorption and heterogeneous adsorption energy. The removal of ions was favored by ion exchange and chemical reaction on monolayers with energetic heterogeneity at the zeolite surface. Pseudo-first order non-linear kinetic models were favorable with (R² ≥ 0.99) indicating the presence of chemisorption. MC modelling showed that ion capture was favorable in neutral media, with individual adsorption energies (dEads/dNi) of -0.03, -0.05, -5.8 and -13.8 kcal/mol for Co, Ni, Sr and In, respectively, in a mixed ion system at 298 K. The affinity of zeolite to adsorbed Co(II) on Ni(II), Al(III), Bi(III), Ca(II), In(III), Sr(II), K(I), Cd(II), Cr(III) and Pb(II) was observed by the highest values of the distribution coefficient (K_d) and low separation factor (α).

Conversion of solid biomass into syngas is often operated in fluidized inert material, where severe operational issues like tar condensation and aerosol formation, corrosion, fouling, are mitigated by integrating specific tar-reducing catalysts (e.g. olivine). However, the resulting ternary bed (biomass, inert and catalyst) is prone to inefficiency owing to solids’ segregation. The present study examines the fluidization and segregation behavior of mixtures of a biomass (crushed olive pits), sand and olivine of given size, shape and density, at different compositions, by an experimental characterization of the voidage, fluidization velocity intervals, vertical concentration profiles and mixing index. Interpretation of these profiles is carried out according to the Particle Segregation Model (PSM). Originally developed for segregation in two-component fluidized beds, the PSM is conceptually extended to three-component systems. Initially, the role of composition is investigated for a biomass-rich and a sand-rich mixture. Given the contrasting sizes and densities, the former system maintains its state of mixing at low olivine fractions (maximum deviation from nominal composition: Δx_S = 0.06). In the sand-rich mixture, the size-segregating behavior leads to modest segregation of the biomass and olivine towards the bed surface (Δx_B = 0.15 max deviation) and sand at the bottom (Δx_S = 0.13 max deviation). In a third examined mixture with extended olivine fraction, a similar behavior to the sand-rich mixture is observed (Δx_S = 0.27 max deviation). Both tendencies are well captured by the PSM, whose analytical formulation allows drawing triangular plots that effectively compare experimental points and equilibrium lines.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"25 ","pages":"Article 100977"},"PeriodicalIF":7.1,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145691905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
