Four key synthesis variables—solvent ratio (BCA/EtOH), ultrasonic power, reaction temperature, and synthesis time—were evaluated using a full factorial design to control the thickness of the carbon layer on Ag–graphene particles. Statistical analysis, including ANOVA and Pareto charts, identified solvent ratio, ultrasonic power, and temperature as significant factors affecting carbon thickness, with time being negligible. Response optimization revealed optimal synthesis conditions that minimize thickness while ensuring uniform dispersion. For binder development, a mixture design approach was employed to determine the ideal proportions of epoxy resin, hardener, and additives. The optimal binder formulation was identified at a ratio of 0.90:0.01:0.09 (Resin:Hardener:Additive), ensuring stability and processability. Finally, Central Composite Design was applied to optimize the conductive paste by evaluating the effects of binder ratio and synthesis temperature on electrical conductivity and shear strength. A total of nine experimental conditions enabled the construction of second-order polynomial models. Statistical analysis confirmed high model significance (<i>P</i> &lt; 0.01) with <i>R</i>² values exceeding 0.95 for conductivity and 0.99 for shear strength. Contour plots revealed that reduced binder content improved conductivity, while both higher binder ratio and temperature enhanced mechanical strength. The optimized conditions achieved a balance between electrical performance and structural integrity, demonstrating the efficacy of the CCD approach for multivariable paste optimization.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"42 12","pages":"2997 - 3008"},"PeriodicalIF":3.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing sustainable methods to convert CO₂ into valuable products is crucial for mitigating global warming and meeting long-term energy demands. The development of novel photocatalysts and the use of solar energy via photocatalysis are key to achieving CO₂-to-CH₃OH conversion. Among these, TiO₂ anatase has shown significant results for photocatalytic CO₂ reduction; however, its high bandgap energy restricts its efficiency in utilizing visible wavelengths, highlighting the need for further optimization. By doping strategy with alkaline earth metal like Mg, it modified the electronic properties of anatase TiO₂ and introduced more Lewis basic sites. Furthermore, Nafion coating facilitates proton-coupled electron transfer (PCET), stabilizes intermediates, and prevents methanol back-oxidation. Under UV–Vis irradiation for 8 h, the CH₃OH yield from the photocatalytic CO₂-to-CH₃OH by Nafion/Mg–TiO₂ is 1559.82 μmol⁻¹ g⁻¹ h⁻¹, outperforming Mg–TiO₂ (1350.20 μmol⁻¹ g⁻¹ h⁻¹) and pristine TiO₂ (930.96 μmol⁻¹ g⁻¹ h⁻¹). Langmuir–Hinshelwood (L–H) kinetic model reveals that CO is an intermediate product in this process, where its subsequent reaction with oxygen produces CH₃OH, marking the rate-determining step. The synergistic effect of Nafion and Mg doping in TiO₂ optimizes acid–base interfaces contributed by Lewis’s base and acidic protonated Nafion, enabling efficient charge separation and enhanced photocatalytic activity. Nafion/Mg–TiO₂ is a promising platform for designing advanced photocatalysts for CO₂ reduction to methanol.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"42 11","pages":"2523 - 2542"},"PeriodicalIF":3.2,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144923259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-pressure hydrogen storage is relatively simple but suffers considerable exergy losses during compression. In contrast, the liquid organic hydrogen carrier (LOHC) system offers advantages in both efficiency and economic feasibility. By thermally integrating LOHC dehydrogenation with fuel cell reactions, the overall system efficiency increases by about 6%, achieving 2% higher exergy efficiency compared to high-pressure storage.

These microdomains—composed of polystyrene (PS) and silica (SiO₂) particles—serve as lateral templates that direct vertical rearrangement during monolayer collapse. Utilizing hydrophilic PS and SiO₂ particles with distinct interfacial adsorption affinities, we demonstrate that depletion interactions and compression-induced instabilities induce domain-selective subduction, a process in which one type of particle domain is driven beneath another. Specifically, more hydrophilic silica domains preferentially collapse and subduct beneath less hydrophilic PS domains, resulting in pronounced vertical asymmetry concentrated at the domain boundaries. Langmuir isotherm analysis and SEM imaging reveal that both the lateral extent of domain segregation and the vertical thickness of the resulting multilayers can be tuned by varying the compression distance and depletant concentration. Lower depletant concentrations reduce depletion pressure, facilitating enhanced particle desorption and enabling the formation of broader and more asymmetric multilayer structures. Importantly, this assembly framework remains effective even when the relative wettability of the particle types is reversed. By introducing sulfonic acid functional groups onto PS, we transform it into a highly hydrophilic species. Adjusting subphase pH to suppress SO₃H dissociation allows both particle types to adsorb at the interface. Under acidic conditions, the PS–SO₃H particles collapse first and subduct beneath silica domains, producing inverted stratification. This inversion confirms that the subduction-driven assembly is not limited to specific wettability pairings, but instead governed by dynamic interfacial energetics and domain interactions.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"42 11","pages":"2661 - 2672"},"PeriodicalIF":3.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144923305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several hundred <i>E. coli</i> strains have been identified to cause diseases ranging from mild, self-limiting gastroenteritis to renal failure and septic shock. Its virulence allows <i>E. coli</i> to evade host defenses and develop resistance to common antibiotics. The aim of our study was to develop an aqueous-soluble cefixime conjugate for the treatment of <i>E. coli</i> infections. Cefixime shows excellent activity against <i>E. coli</i> strains. However, it has poor aqueous solubility. Thus, it was conjugated with gelatin using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) to produce a Cefixime–gelatin chemical conjugate (CGcc) with a significantly higher solubility than that of the pure drug, which may produce a better therapeutic effect. The conjugate was characterized using spectral data. The conjugate was determined to be non-hemolytic and non-toxic to L929 cells. The antibacterial activity of CGcc against <i>E. coli</i> was evaluated in vitro using the disc-diffusion method. The results showed that CGcc was slightly soluble in methanol, but very soluble in water and PBS, and its melting point was found to be 224–230 °C. The SEM images revealed that the CGcc exhibited a spherical morphology. All spectral data support the chemical conjugation of gelatin. The conjugation efficiency of CGcc was 74.54 ± 3.358%. In addition to its hemocompatibility and biocompatibility, CGcc exhibited enhanced solubility.
