The X-ray diffraction shows that samples are in single rhombohedral phase. The Raman signals of LCO were quite small in comparison to LBCO, which exhibited a Raman peak above 675 cm−1. The band seen with a wavenumber of 484 cm−1 corresponds to the vibrational modes of E\u0000 g bending and Ba–O stretching. UV–DRS and photoluminescence spectra indicated broad absorption over the ultraviolet, visible, and near-infrared spectrums. Surface morphology and EDAX spectra corroborated the materials homogeneous size distribution and homogenous microstructure, with Ba indicating a more stable structure. XPS was used to study chemical states of LBCO and found Co (2p), La (3d), O (1s), and C (1s) elements in perovskite compounds. A peak beneath 300 eV indicated adventitious carbon on surface materials. XPS survey spectrum elements La, Ba, Co, and O had their own binding energies. The magnetization-field dependency of LBCO at 300 K showed that Ba insertion into the LCO switched it from paramagnetic to weak ferromagnetic. Ba considerably decreased magnetic saturation and coercivity, influencing magneto-crystallites’ anisotropy and coercive field.","PeriodicalId":506520,"journal":{"name":"Zeitschrift für Physikalische Chemie","volume":"163 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140249634","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}

Thermoelectric power generation is a promising technology by converting this irrecoverable waste heat directly into electricity without any greenhouse gas emission.

Interestingly, there is a less explored connection between obesity and compromised leptin function. Prior studies have highlighted the limited availability of drugs to address this issue hence, the relentless struggle against obesity persists and the need to develop new therapeutic strategies becomes necessary. In the present study, fatty acids from the seed of Cola lepidota were utilized to prevent antibody Fab fragment (9F8) (3VG0), an antagonist of leptin from binding to the leptin pocket of the human obesity receptor (ObR) thereby restoring ‘satiety’. This study is the first to investigate the effect of plant derived fatty acids from C. lepidota seed for the purpose of reversing leptin resistance in obesity condition. Our research employed experimental GCMS extraction technique and theoretical FT-IR and UV–vis analysis and compared result with those reported in literature. All computational methodologies were carried out within the framework of density functional theory (DFT) at the B3LYP/6-311++G(d,p) level of theory while molecular docking and pharmacokinetics studies were employed to investigate the biological activities and druglikeness of the compounds. Result shows that linoleic acid (LA), methylhexadecanoate (HXD), ocatadecanoic acid methyl ester (ODA) and Bis(2-ethylhexyl) phthalate (BISP) recorded energy gaps of 2.8216 eV, 7.4230 eV, 7.4244 eV, and 5.5849 eV respectively, suggesting that LA is the most reactive while BISP is the most stable as they recorded lowest and highest energy gaps respectively. The dipole moment (μ) result shows that LA recorded the highest dipole moment at 6.1119 Debye (D) indicating that it has the highest polarizability capacity. The order of polarizability is LA > BISP > HXD > ODA. The visualized electron localization function result shows that the red regions are electron rich, followed by yellow region then green and finally blue region. Electron density was distributed within the O and H atoms of the molecules indicating strong electronegativity nature of oxygen and hydrogen atoms of the compounds. LA, ODA and HXD absorbed light at the vacuum level UV region while BISP absorbed light at the UV visible region.
