Journal ArticleDOI
Structure and NIR-luminescence of ytterbium(III) beta-diketonate complexes with 5-nitro-1,10-phenanthroline ancillary ligand: assessment of chain length and fluorination impact
Pablo Martín-Ramos,P. S. Pereira Silva,Víctor Lavín,Inocencio R. Martín,F. Lahoz,Pedro Chamorro-Posada,Manuela Ramos Silva,Jesús Martín-Gil +7 more
TL;DR: F fluorination of the ligands is only advised when the complexes are to be used for co-doping with isostructural Er(3+) complexes for optical amplifiers, since it leads to a slight decrease in luminescence intensity for the same β-diketonate chain length.
Journal ArticleDOI
First exposure to Arduino through peer-coaching
Pablo Martn-Ramos,Maria Joo Lopes,M. Margarida Lima da Silva,Pedro E.B. Gomes,P. S. Pereira Silva,Jos P.P. Domingues,Manuela Ramos Silva +6 more
TL;DR: The jeKnowledge academy courses to actively engage Portuguese high-school students in STEM education through hands-on projects based on the low-cost Arduino platform resulted in high degrees of satisfaction for both the student tutors and their tutees.
Journal ArticleDOI
Experimental and theoretical studies of the second- and third-order NLO properties of a semi-organic compound: 6-Aminoquinolinium iodide monohydrate
P. S. Pereira Silva,Hasnaa El Ouazzani,M. Pranaitis,Manuela Ramos Silva,Cláudia T. Arranja,Abilio J.F.N. Sobral,Bouchta Sahraoui,José A. Paixão +7 more
TL;DR: In this article, a new semi-organic compound, 6-aminoquinolinium iodide monohydrate (I), has been synthesized and characterized by single crystal X-ray diffraction, UV-vis absorption and fluorescence spectroscopy and nonlinear optical measurements.
Journal ArticleDOI
Active layer solution-processed NIR-OLEDs based on ternary erbium(III) complexes with 1,1,1-trifluoro-2,4-pentanedione and different N,N-donors
Pablo Martín-Ramos,Carmen Coya,Víctor Lavín,Inocencio R. Martín,M. Ramos Silva,P. S. Pereira Silva,Miguel García-Vélez,Ángel Luis Álvarez,Jesús Martín-Gil +8 more
TL;DR: Three new ternary erbium(iii) octacoordinated complexes have been synthesized and the best electroluminescence results correspond to the OLED based on the [Er(tfac)3(bath)], as a consequence of the superior electron transport capabilities of bathophenanthroline.
Journal ArticleDOI
Potent acetylcholinesterase inhibitors: Synthesis, biological assay and docking study of nitro acridone derivatives
Mehtab Parveen,Afroz Aslam,Shahab A.A. Nami,Ali Mohammed Malla,Mahboob Alam,Dong-Ung Lee,Sumbul Rehman,P. S. Pereira Silva,M. Ramos Silva +8 more
TL;DR: The in vitro efficacy of the compounds for their acetylcholinesterase (AChE) and antimicrobial inhibitory activities have been evaluated against the standard drugs Ampicillin and Gentamicin against Gram positive and Gram negative bacteria.
