An ionic liquid (B4PBF₄) was synthesized and characterized using spectroscopic techniques, incorporating it in different proportions (0.25, 0.5, 1.5% w/w) into thin perovskite films. The results show that 1.5 % concentration significantly improves the optical properties by minimizing trap states preventing charge recombination. XPS analysis indicates a strong interaction between lead halides at this proportion. Additionally, photovoltaic devices fabricated with percentage achieved higher...
The incorporation of new quaternized theophylline and BF 4 additives in MAPbI 3 perovskite solar cells increases efficiency stability controlled humidity.
Water-soluble Carbon Quantum Dots (CQDs) featured with blue fluorescence were prepared by electrochemical synthesis at room temperature using carbon electrodes as a source and encapsulated in liposomes of DMPC (1,2-dimyristoyl-sn‑glycero-3-phosphocholine) single quick step. The system liposome-CQDs was characterized UV–vis absorption spectroscopy, microscopy, scanning electron Fourier transform infrared spectroscopy epifluorescence microscopy. Electrochemical studies, such cyclic voltammetry...
In this work, two oligophenyleneimines type pentamers with terminal aldehydes, designated as DAFCHO (4,4'-((((((2,5-bis(octyloxy)-1,4-phenylene)bis(methanylylidene))bis(azanyl ylidene))bis(9H-fluorene-7,2-diyl))bis(azanylylidene))bis(methanylylidene))bis(2,5-bis(octyloxy) benzaldehyde)) and FDACHO (4,4'-((((((2,5-bis(octyloxy)-1,4-phenylene)bis(methanylylidene))bis (azanylylidene))bis(4,1-phenylene))bis(azanylylidene))bis(methanylylidene))bis(2,5-bis(octyloxy) were synthesized by...

En este trabajo de investigación se sintetizaron polvos Fe(Cr, Al)2O4 , a partir sobrantes acero inoxidable y latas aluminio por los métodos disolución metales, coprecipitación calcinación, en una atmósfera ausencia aire, el composite obtenido forma polvo presentó un color café obscuro con propiedades magnéticas. La caracterización DRX reveló la obtención Al)2O4, su estructura cristalina tipo espinela.
In the present work, three aqueous media were used: sodium acetate (NaC2H3O2), potassium nitrate (KNO3) and (NaNO3) at two different scanning speeds, i.e. 50 100 mVs−1, to evaluate bandgap of conjugated oligophenylenimine called DAFCHO by cyclic voltammetry (CV). was synthesised solid-phase mechanosynthesis from 2,7-diaminofluorene 2-5-bisocycloxyterephthaldehyde deposited as a film on glass substrate. The results showed an electrochemical range 2.39 2.47 eV mVs−1 2.59 2.68 which are close...
