Interaction energy calculations, as well as other analyses including QTAIM, SAPT0, NCI and EDD were conducted to analyze how drug molecules interact with the CTF-0 framework. The adsorption energies of −22.49 and −24.77 kcal/mol for MET@CTF-0 and CPD@CTF-0 respectively, suggest strong host-guest interactions between studied systems. NCI and QTAIM analyses revealed that both drugs are mainly stabilized by the van der Waals interactions and hydrogen bonds, while SAPT0 affirms the role of dispersive forces in stabilizing these types of host-guest interactions. Charge transfer from the host molecule to the drugs was studied through EDD and NBO calculations. The reduced band gap from 8.19 eV to 6.67 eV after adsorption of MET suggests that MET is more electronically responsive. Dipole moment for both complexes demonstrates their good solubility in polar solvents. MD simulation results indicate that both complexes maintain their structural integrity throughout the 200 ns simulation period. Overall, these findings indicate that CTF-0 can be considered as an efficient carrier to deliver anti diabetic drugs, particularly metformin.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"186 ","pages":"Article 116320"},"PeriodicalIF":5.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147384659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

W₁₈O₄₉ was synthesized using the solvothermal method, yielding nanoparticles along with sparsely separated nanorods. The intrinsic properties (i.e., crystal structure, morphology, and defect states) of the W₁₈O₄₉ were examined. While operating at RT, the W₁₈O₄₉-based gas sensor demonstrated superior behavior to acetone among eight (8) other tested gases (ethanol, methanol, m-xylene, p-xylene, o-xylene, benzene, CO, and NO₂). The sensor was exposed to a minimal concentration of 0.08 ppm acetone, resulting in a response (R_a/R_g) of 1.04. At 1.8 ppm, the response was 1.49, respectively. The repeatability measurements at 1.8 ppm revealed that the sensor could output a constant response over multiple cycles, with a standard deviation in the spread of the data of 0.1 ppm. Relative humidity (RH) measurements indicated that the sensor performed optimally in humid conditions, suggesting that humidity acted as a catalyzing agent. The sensor displayed the best responses to acetone at lower concentrations than the other gases. The underlying data was then used for Principal Component Analysis (PCA) analysis and the k-Nearest Neighbor (kNN) algorithm. The PCA plot of the sensor responses clearly showed well-separated clusters for the tested gases, indicating that the W₁₈O₄₉-based sensor produced distinct response patterns suitable for data-driven classification. Then, the PCA-kNN classification algorithm achieved a recognition accuracy of 93%, confirming the sensor system's excellent ability to differentiate acetone from other VOCs, even at trace levels. This highlights the benefit of combining nanostructured W₁₈O₄₉ sensing materials with Machine-Learning tools for reliable VOC detection in complex environments. Density Functional Theory analysis was then performed to understand the affinity of the sensor towards acetone compared to the other gases tested. Finally, a proposed sensing mechanism was discussed in detail.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"186 ","pages":"Article 116164"},"PeriodicalIF":5.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146035585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting nanoceramics were examined through a range of spectroscopic and analytical techniques to comprehensively evaluate their particle size, morphology, crystallinity, thermal behaviour, surface characteristics, and magnetic responses. X-ray diffraction (XRD) confirmed the formation of well-defined crystalline phases, revealing a tetragonal structure for the undoped sample and a gradual transition toward a cubic spinel structure with increasing Er³⁺ substitution. The lattice parameter was found to increase as more Er³⁺ ions were incorporated into the lattice. Fourier transform infrared spectroscopy (FTIR) and Raman spectra exhibited the characteristic asymmetric stretching vibrations associated with the AB₂O₄ spinel framework. Field Emission Scanning Electron Microscopy (FE-SEM) micrographs provided insight into the microstructure, while Energy-Dispersive X-ray Spectroscopy (EDX) and Inductively Coupled Plasma Optical Emission spectroscopy (ICP-OES) verified the presence of the constituent elements and elemental mapping confirmed the uniform distribution of the elements in the synthesized samples.

Overall, the results indicated that the catalyst performed efficiently in promoting heterogeneous oxidation.
