The dye structure was designed with N, N-dimethylaniline as a donor, fluorophenyl as an π-conjugated bridge, and cyanoacetic acid as an anchoring and acceptor group. The fluorine substituents are strong electron-withdrawing groups, introducing different numbers and positions of fluorine atoms (ortho and meta) that were expected to the ability of the acceptor parts of the dye. The results showed that adding the fluorine mono-substitution in the ortho position can enhance the efficiency of the solar cells in comparison with the meta-substitution and unsubstituted one. However, the di-substitution by fluorine atoms in two ortho positions and ortho, meta positions reduced the performance of the solar cells. The reason was related to the effect of π-conjugation between the fluorine substituent and the carbonyl group of the carboxylic acid. The DSSCs based on dye 14 achieved the best results with power conversion efficiency (PCE) = 3.33%, (Jsc = 5.43 mA cm-2, Voc = 0.81V and FF = 75.85%) under standard conditions with I3-/I- as the electrolyte.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136184131","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}

Cyclization of 5- floro-2-furaldehyde, ethyl acetoacetate, and urea or thiourea by LaCl3.7H2O, addition of hydrazine to form amine derivatives were performed, and respective Schiff base derivatives (L1, L2) were produced by adding acetyl coumarin in an ethanolic solution at ambient temperature. New ligands and its complexes of the V (IV), Fe (III) and Mn (II) ions were characterized using (FT-IR, UV, MS) and nuclear magnetic resonance (1H-NMR) as well as elemental analysis (CHN). The synthesized complexes chelate with ligands L1, L2 via (N, O2) atoms. The structural geometry of the complexes was illustrated in the solid phase using FT-IR and UV-VIS spectroscopy, elemental analysis (CHNS), and flame atomic absorption, in addition to magnetic susceptibility and conductivity measurement. The antibacterial activity of the newly prepared ligands and their metal complexes was evaluated against Pseudonomous aerugionosa as a gram negative and Bacillus subtilis as a gram positive microorganism. Moreover, the antifungal activity against two fungi Aspergillus flavus, and Saccharomyces cerevisiae was studied for all compounds. The coordinated ligands significantly increased their bactericidal and fungicidal action compared to the free ligands, which did not exhibit any activity against the selected fungal and bacterial strains.

The preparation of PLGA-PEG/HAP composite films was achieved using a simple methodology, including mixing, sonication, and casting-drying stages. Characterization analyses, including FTIR, SEM, TGA-DSC, and XRD, were conducted to assess the properties of the composite films. The results showed that the PEG polymer decreased the glass transition temperature of the composite, while the HAP did not change. Further, weight remaining (%) values of HAP, PLGA-PEG, and PLGA-PEG/HAP were found as 94.04, 88.28, and 90.57, respectively. Thus, it can be concluded that HAP improves the thermal stability of PLGA-PEG. The outcomes of the analysis, encompassing the evaluation of physical, morphological, and thermal properties, demonstrate that the composite structure comprising PLGA and PEG polymers along with HAP ceramic material may attain the intended quality. Moreover, fluorescence microscopy was employed to visualize the interaction between cells and the composite films following DAPI staining to evaluate cell adhesion and proliferation on the PLGA-PEG/HAP composite films. PLGA-PEG/HAP composite films have no adverse effects on cells, such as toxicity, and they have also exhibited a favorable influence on cell proliferation, supporting an augmentation in cellular growth and adhesion. Overall, the results indicate that the synthesized PLGA-PEG/HAP composite films may hold the potential to serve as a promising candidate for applications in the field of bone tissue engineering.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135131788","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 determination of the surface properties of a solid material is extremely important for the industrial use of the material and the improvement of material properties. Therefore, in this study, this plant was used as a stationary phase, and its surface characterization was performed by inverse gas chromatography technique. In this context, firstly, the plant was prepared with several pretreatments to be used in the experimental tests. The V_N values were found from the retention data obtained by passing organic solvents over the plant filled into the chromatographic column in the temperature range of 303.2–328.2 K and linear retention diagrams were drawn. The γ_S^D of the plant was calculated according to Schultz, Dorris-Gray, and Donnet-Park methods, and the suitability of the methods was compared. The 〖∆G〗_A^S values were calculated with the data obtained from the Schultz method, and the 〖∆H〗_A^S values were calculated using these data. The acidity and basicity of the plant surface were examined. According to the K_D⁄K_A value (0.93), it was determined that the surface of the plant was acidic.","PeriodicalId":17402,"journal":{"name":"Journal of the Turkish Chemical Society, Section A: Chemistry","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136072474","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}
