Through the Pareto analysis, it was identified that the ethanol-water ratio is the critical variable for maximizing phenolic content. The determined ideal conditions were 0.90 mL of ethanol per mL of water, 120 min of extraction, and 400 rpm. Notably, a 50:50 ethanolic extract exhibits superior antioxidant activity, underscoring the importance of solvent composition. Weight loss measurements (200 to 1700 ppm) at 303 to 333 K indicate increased efficiency with specific solvent proportions, with freeze-drying yielding slightly better results (95.88 %) than rotatory evaporation (89.49 %). Also, it was noticed that temperature enhances adsorption of organic compounds, with best inhibition observed at 1700 ppm, favoring improved performance. Electrochemical results indicated that the inhibitor efficiency decreases over time due to desorption, while surface characterization through confocal laser scanning microscopy confirmed reduced roughness in the presence of the inhibitor and incipient localized corrosion. Additionally, synergistic effects with intensifiers such as KI and DMSO (dimethyl sulphoxide) are noted, leading to enhanced corrosion protection (95.21 %) in aggressive acidic environments (15 % HCl). Overall, the broccoli-derived inhibitor demonstrates potential for effective corrosion inhibition for carbon steel across mild and aggressive acidic conditions.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"17 ","pages":"Article 102562"},"PeriodicalIF":2.5,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704194","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}

Bandgap engineering and surface modifications of the photocatalyst are crucial to effectively generating H₂ in the visible range and improving charge carrier (CC) usage. In this investigation, the simple hydrothermal method was used to develop an effective and stable Cu/Zr/TiO₂ (CZT) nanocomposite-based photocatalyst for hydrogen generation. The CZT nanocomposite-based photocatalyst was investigated for various structural, morphological, and optical characteristics. The XRD analysis disclosed the highly crystalline structure of the nanocomposite, while SEM images depicted an aggregation of small, roughly cubic, and irregularly shaped particles. Further, the effective electron transport was rendered by the CZT nanocomposites-based photocatalyst, which in turn facilitated the separation and movement of photogenerated charge carriers in a particular direction. The optimized CZT photocatalyst achieved an impressive H₂ production rate of 1241 μmol·g⁻¹·h⁻¹, significantly surpassing that of pristine TiO₂ nanoparticles (NPs) (561 μmol·g⁻¹·h⁻¹), Zr/TiO₂ (578 μmol·g⁻¹·h⁻¹), and Cu/TiO₂ NPs (693 μmol·g⁻¹·h⁻¹) by factors of 2.21, 2.15, and 1.79, respectively. Additionally, the CZT nanocomposite demonstrated exceptional stability, maintaining a consistent H₂ evolution rate over four consecutive photocatalytic (PC) cycles, confirming its durability. The enhanced H₂ evolution rate is due to synergistic characteristics of nanocomposites, including efficient electron transport, particle shape and size, oxygen vacancies, and improved visible light (VL) absorption.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"17 ","pages":"Article 102561"},"PeriodicalIF":2.5,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704195","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}

The characterization of the as-produced C-dots was conducted through the measurement of their absorption (Abs), photoluminescence (PL), and FTIR spectra before and after synthesis with Zn²⁺ ions, X-ray diffraction (XRD) patterns and transmission electron microscopy (TEM) image. The Abs spectrum of these C-dots demonstrated two Abs peaks at 250 and 292 nm corresponding with π → π* and n → π* transitions, respectively. The appearance of these two Abs peaks confirmed the formation of the C-dots from dragon fruit peel in ethanol solution. By using an excitation wavelength of 350 nm, the PL peak at 434 nm corresponds to the blue emission color of typical C-dots. Thus, the FTIR spectrum strongly displayed O<img>H and C<img>O bonds as hydroxyl and carbonyl groups on the surface of the C-dots, respectively. The characterization of XRD patterns and TEM image displayed an amorphous state and dispersed spherical shape of C-dots, respectively. Fortunately, the PL intensity of these C-dots quenched after coordination with Zn²⁺ ions with the enhancement of the concentration of Zn²⁺ ions.

Also, their antibacterial effectiveness against <em>Escherichia coli</em> (<em>E. coli</em>) and <em>Staphylococcus aureus</em> (<em>S. aureus</em>) were tested. The scaffolds were prepared with 1 % and 1.5 % κ-carrageenan and cross-linked with glutaraldehyde.

The scaffolds were loaded with Lawsone, and their antibacterial properties against <em>E</em><em>.</em> <em>coli</em> and <em>S</em><em>.</em> <em>aureus</em> were investigated using the disk diffusion method. The result was that all scaffolds had a sponge-like structure, a desirable porosity of 50–80 %, and a pore size of 30–260 μm. The degradation rate over 35 days was less than 30 %, which was satisfactory, and the scaffolds containing 1.5 % κ-carrageenan showed better hydrophilicity than others.

The raw macadamia nutshell and MMN were characterized using several analytical techniques: Fourier Transform Infrared (FTIR) spectroscopy for functional groups, X-ray Diffraction (XRD) for crystallinity, Scanning Electron Microscopy (SEM) for surface morphology, and Brunauer-Emmett-Teller (BET) analysis for textural properties. Various experimental factors affecting CV adsorption were investigated, including contact time, dosage, pH, temperature, initial concentration, particle size, and water chemistry. The results showed that CV removal reached equilibrium within 5 min and remained nearly constant thereafter. The optimal dosage and pH for CV removal were 0.2 g and 4, respectively. Higher temperatures enhanced CV removal efficiency, while changes in water chemistry significantly influenced the sorption process. The adsorption process was best described by the Freundlich isotherm, and the kinetics followed a pseudo-second-order model.

Batch adsorption experiments were conducted under varying pH (2−10), contact time (10–60 min), temperature (298–343 K), and initial concentration (100–500 mg/L). Adsorption isotherms were analyzed using Langmuir, Freundlich, Redlich–Peterson, Toth, and other models. The Langmuir model best described the data (R² &gt; 0.999), indicating monolayer adsorption with maximum capacities of 145.71 mg/g for Cd²⁺ and 81.44 mg/g for Cu²⁺. Kinetic analysis showed that the pseudo-second-order (PSO) model best fit the data (R² &gt; 0.998), suggesting chemisorption as the dominant mechanism. Thermodynamic parameters (ΔG°, ΔH°, ΔS°) were calculated from Van't Hoff plots. Negative ΔG° values confirmed spontaneity, while positive ΔH° and ΔS° supported the endothermic and entropy-driven nature of the process. Statistical physics modeling further revealed the number of active sites, the mean adsorption energy (E &lt; 20 kJ/mol), and the adsorption stoichiometry factor (n). These results indicated predominant physisorption with partial chemisorption, particularly for Ni²⁺ and Cu²⁺.
