Pd²⁺ on the SSCs enhanced the adsorption of CH₂N₂ through electrostatic interaction, efficiently forming metal carbene. The conversion and selectivity of norbornene cyclopropanation reached 99.9% and 96.9%, which are much higher than those of commercial Pd/C (conversion 42.3%, selectivity 80.8%). In addition, the obtained tricyclooctane shows excellent properties (density 0.93 g/cm³, calorific value 42.75 MJ/kg) to be a promising high-performance rocket fuel.

Addressing this, we developed a ceramic–metal composite membrane using 2D SnO₂ with blade-shaped pore walls and tunable pores (0.68–7.92 μm) via in situ hydrothermal synthesis. The blade-shaped pore walls reduce liquid metal surface tension, enabling smooth extrusion through pores while suppressing aggregation. This design leverages the membrane’s large metal contact angle and structural robustness to enhance emulsification under harsh conditions. The resultant microspheres exhibit precise size control (average particle size: 8.79–35.89 μm) and narrow distribution (Span: 0.41–0.84), outperforming traditional methods. By integrating adjustable pore engineering with ceramic–metal interfaces, this work establishes a scalable strategy for fabricating functional membranes tailored to high-surface-tension systems.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"51 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fini","doi":"10.1021/acs.iecr.5c00993","DOIUrl":"https://doi.org/10.1021/acs.iecr.5c00993","url":null,"abstract":"Moisture susceptibility is a major contributor to asphalt pavement deterioration, leading to increased maintenance costs and reduced service life. Despite the known importance of moisture damage, the molecular mechanisms by which oxidative aging influences water diffusion in bitumen─the primary binder in asphalt─remain insufficiently understood. This study aims to bridge that knowledge gap by examining how thermal aging alters the moisture resistance of bitumen through changes in its molecular structure and interfacial behavior. We employed differential Fourier transform infrared (D-FTIR) spectroscopy to monitor real-time water diffusion in thin films of thermally aged and unaged bitumen. Additionally, we used density functional theory (DFT) calculations to quantify water–bitumen interactions and identify how aging-induced chemical modifications affect bitumen’s polarity. D-FTIR analysis revealed that thermal aging significantly increased water uptake across all bitumen grades tested, with aged samples showing faster and more sustained diffusion. The spectra also showed codiffusion of polar bitumen components─particularly resins and asphaltenes─toward the water-exposed surface, while nonpolar molecules migrated away. DFT results confirmed that these polar compounds exhibit higher interaction energies with water, and that oxidation introduces polar functional groups (e.g., carbonyl and sulfoxide) that enhance hydrogen bonding and electrostatic interactions with water molecules. Overall, this work demonstrates that oxidative aging promotes water adsorption and accelerates diffusion by increasing molecular polarity and inducing surface redistribution of bitumen components. These findings offer important insights for the development of more durable, moisture-resistant bitumen formulations, ultimately supporting longer-lasting and more sustainable asphalt pavements.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"3 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Insights into the Electrolyte Roles of Electrochemically Activated Peroxymonosulfate in a CeO2 Electrode for RhB Degradation","authors":"Jing Di, Shihao You, Zhibo Li, Ruiqin Yang, Qixin Yang, Yin Li, Yesong Gao, Xikun Gai","doi":"10.1021/acs.iecr.5c00866","DOIUrl":"https://doi.org/10.1021/acs.iecr.5c00866","url":null,"abstract":"In the electrochemically activated peroxymonosulfate (EC-PMS) process, the electrolyte plays a pivotal role affecting the degradation efficiency, reusability, and cost. However, the function of the electrolyte on active species and degradation pathways remains uncertain to date. To address this, this study explores the degradation of Rhodamine B (RhB) using EC-PMS with a CeO₂ electrode (EC/CeO₂ + PMS) under three electrolytes (H₂SO₄, Na₂SO₄, and NaOH). While Na₂SO₄ was used as the electrolyte, the EC/CeO₂ + PMS system achieved 46.6% RhB removal within 60 min (100 mg/L RhB, 0.5 g/L PMS, and −10 mA/cm²), outperforming standalone PMS (30.8%) or EC (17.7%) systems. Notably, Ce ion leaching was electrolyte-dependent. The value reached 6.2 mg/L in H₂SO₄, while it remained much lower in Na₂SO₄ (0.06 mg/L) and NaOH (0.08 mg/L), demonstrating exceptional stability in neutral/alkaline conditions. Further analysis indicated that electrochemical activation could efficiently accelerate the Ce⁴⁺/Ce³⁺ circulation, thereby significantly enhancing the degradation process. Quenching experiments and electron spin resonance studies exhibited that the primary radicals varied depending on the electrolyte. Surface-bound radicals were the dominant reactive oxidation species in the H₂SO₄ electrolyte, while surface-bound radicals and singlet oxygen (¹O₂) codominated in the Na₂SO₄ electrolyte. In contrast, ¹O₂ was the main species in the NaOH electrolyte. Finally, the degradation pathways in different electrolytes were proposed based on the analysis of intermediates. The findings underscore a previously underestimated significance of electrolyte choice in the EC-PMS process and provide valuable understanding for efficient removal of organic pollutants using electrochemical PMS activation.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"48 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144146313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report an efficient and mild strategy for the rapid preparation of green-emissive CDs (G-CDs) via a microwave-assisted approach. The G-CDs were synthesized via microwave-assisted thermal treatment of <i>m</i>-phenylenediamine (<i>m</i>-PD) and phthalic acid in ethylene glycol for 10 min, followed by purification. The resultant G-CDs exhibit a bright green photoluminescence (PL) centered at 515 nm with an absolute quantum yield (QY) of 66.5%. Structural characterization revealed that the G-CDs possess a highly graphitized carbon core and are enriched with various surface functional groups. Mechanistic studies on fluorescence indicated that the green emission of G-CDs originates from the interaction between the surface-attached green fluorophore, phenazine-2,7-diamine (2,7-DAP), and the graphitized carbon core. In addition, the prepared G-CDs/polyvinylpyrrolidone (G-CDs/PVP) composite film exhibits excellent optical properties and was successfully applied in the fabrication of green light-emitting diodes (LEDs).

A thorough investigation of the esterification kinetics of SMA and sorbitol as well as the average reacted hydroxyl number (Ne) of sorbitol was conducted by a combination of Fourier transform infrared spectroscopy (FT-IR) and potentiometric titration.

The apparent viscosity of aqueous solutions thickened by SMA-<i>g</i>-sugar (alcohol) before and after further chain extension with diamine was evaluated by using a rotational rheometer. After chain extension with polyetheramine D230, great thickening property and excellent stability against thermal cycles and shear time can be achieved.
