High-performance hydrogen sulfide gas sensor based on Pd/Fe 2 O 3 –Zr 4 MnO 10 : working conditions optimization by response surface methodology J. Iran. Chem. Soc. (IF 1.552) Pub Date : 2020-08-05 Wenjuan Zhang, Fuxiu Yang, Hong Wang, Chunxiu Gu, Yun Lu, Kaowen Zhou
Sensitive materials in gas sensors sometimes need to be activated at a certain high temperature. High working temperature, however, is one of the main obstacles of fabricating gas sensor. In this paper, a hydrogen sulfide gas sensor based on cataluminescence at lower temperature than 150 °C was reported. The sensitive material, Pd-doped Fe2O3–Zr4MnO10, was synthesized via precipitation and impregnation

Self-association process of tetracycline antibiotic in different aqueous solutions: a joint experimental study and molecular dynamics simulation J. Iran. Chem. Soc. (IF 1.552) Pub Date : 2020-08-04 Mahtab Nabavi, Mohammad Reza Housaindokht, Mohammad Reza Bozorgmehr, Abbas Sadeghi
Tetracycline is one of the most commonly used antibiotics in a wide range of antibacterial drugs. Self-association of drugs (e.g. antibiotics) causes problems, such as increasing toxicity and reducing penetration of drugs through cell membranes. In this study, the self-association process of tetracycline was investigated experimentally and theoretically in aqueous, ethanol, and salt solutions. Spectroscopy

Studies of the photocatalytic and electrochemical performance of the Fe 2 O 3 /TiO 2 heteronanostructure J. Iran. Chem. Soc. (IF 1.552) Pub Date : 2020-08-03 Abdelhak Othmani, Salah Kouass, Thamer Khalfi, Sabrine Bourchada, Fathi Touati, Hassouna Dhaouadi
The α-Fe2O3/TiO2 nanostructure material, synthesized on FTO (fluorine-doped tin oxide) substrate using the hydrothermal method at 180 °C for 5 h, exhibits an enhanced performance in the photocatalytic degradation of an organic dye. The optical band gap was found to decrease compared to the TiO2 one. The photocatalytic performances of the as-prepared heterojunction were evaluated with the degradation

MP2/aug-cc-pVDZ calculations were employed to interpret the molecular interactions of iminophosphorane (IP) and HSX (X = F, Cl and Br). The halogen bond (X···N), hydrogen bond (H···N, H···X, H···S) and S···N interactions were found for complex formation between IP and HSX molecules. Among the predicted models, the S···N and H···N interactions have been recognized as important types of these interactions
