Our study used the SS-FCCVD method to grow vertically aligned carbon nanotubes (VACNTs) on an alumina ceramic reactor surface at 850 °C under a nitrogen atmosphere. The experimental setup included a camphor/ferrocene ratio of 20:1 and a specific temperature gradient of 21 °C/cm. To minimize the catalyst agglomeration, we positioned the chemical sources at a distance of 15 cm from the inlet of the CVD reactor. Alumina ceramic surfaces proved highly effective for VACNT production, showing minimal agglomeration of iron particles, facilitating the formation of reactive sites essential for VACNT growth. The VACNTs grew readily on alumina ceramic surfaces, forming bundled, forest-like structures with segment lengths up to 1.2 mm and diameters around 60 nm. When compared to conventional substrates, the surface area of the reaction zone substrate increases by up to 705%, resulting in a significant boost in VACNT yield. A detailed evaluation of characterization results confirmed the growth mechanism and behavior of Fe particles such that carbon-encapsulated particles are attached to the inner and outer surfaces of the CNTs. These VACNT surfaces exhibited superhydrophobic properties, similar to the lotus leaf effect. The synthesized iron-dispersed CNTs exhibit exceptional efficiency in Chromium (VI) removal, with an impressive adsorption capacity of 0.206 mmol/m², positioning them as a promising solution for effective water treatment. This scalable SS-FCCVD method using the ferrocene route achieved the longest VACNTs reported to date.</p></div>","PeriodicalId":496,"journal":{"name":"BMC Chemistry","volume":"19 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://bmcchem.biomedcentral.com/counter/pdf/10.1186/s13065-025-01460-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, “green” chemical procedures are being gradually included in science for sustainable development. This concept has been extended and inspired chemists to fabricate novel green carbon dots (CDs) from natural plants. Herein, we represent novel CDs synthesized by recycling seeds obtained from bell pepper as fluorescent probe for the determination of Edoxaban tosylate hydrate (EDO) a non-fluorescent drug; we exploit the advantage of the inner filter effect between the absorption peak of the drug and the emission peak of the CDs. This overlap resulted in quenching the fluorescence of CDs by increasing the concentration of EDO within the range 0.80–20.00 µg/mL with a limit of detection 0.23 and 0.22 µg/mL and a limit of quantitation 0.69 and 0.72 µg/mL for Microwave CDs and Plate CDs, respectively, at λ_ex/λ_em 310/409 nm. Two facile preparation techniques for the CDs were used, the microwave-assisted method and the thermal decomposition method, using a single-step approach. The fabricated CDs were characterized using various techniques, including UV-vis, fluorescence and Fourier transform infrared spectroscopies, energy-dispersive X-ray, high-resolution transmission electron microscope, X-ray Diffaction, X-Ray photoelectron spectroscopy and zeta potential. The performance of the synthesized fluorescent probe for the determination of EDO was evaluated according to ICH guidelines. The accomplished results, together with the simplicity, sensitivity, and low cost of the developed probe, recommended its appropriateness for the routine quality control assay of EDO pharmaceutical formulation, as good % recovery was obtained upon the investigation of the marketed tablets with 99.77% and 98.79% recoveries for microwave CDs and plate CDs, respectively.

This requires continuous and competitive attempts to achieve the sustainable development goals at every step of the analytical methodology by adhering to the principles of green, blue and white analytical chemistry.

The herein illustrated work represents a comparative study between two newly developed normal-phase and reverse-phase HPTLC methods for the simultaneous quantitative determination of Remdesivir (RMD), Favipiravir (FAV) and Molnupiravir (MOL). For normal-phase HPTLC method, the employed mobile phase consisted of ethyl acetate: ethanol: water (9.4:0.4:0.25, v/v), while, for reverse-phase HPTLC procedure, a greener mobile phase was employed consisting of ethanol: water (6:4, v/v). For both methods, detection wavelength of RMD and MOL was 244 nm while FAV was detected at 325 nm. Both methods were validated following the International Council for Harmonisation (ICH) guidelines with respect to linearity, range, accuracy, precision and robustness. The two established methods were proved to be linear over the range of 50-2000 ng/band for FAV and MOL and over the range of 30–800 ng/band for RMD. The excellent linearities were proved by the high values of correlation coefficients not less than 0.99988. The developed methods were successfully applied for the determination of the three drugs in their bulk form and in their pharmaceutical formulations. Furthermore, a thorough comparative and integrative trichromatic evaluation of sustainability of the designed methods was performed. The Analytical Eco-Scale, the novel Modified Green Analytical Procedure Index (MoGAPI) (2024) and the Analytical GREEnness (AGREE) metrics were applied for greenness assessment and the recent Blue Applicability Grade Index (BAGI) (2023) tool was employed for blueness evaluation.
