Lead-free FASnI3 laser amplifiers integrated in flexible waveguides
(Optica Publishing Group, 2022)
A FASnI3 lead-free perovskite is integrated in a flexible waveguide to demonstrate Amplified Spontaneous Emission. An extremely low threshold, 1 µJ/cm2, is observed together with the formation of narrow random lasing lines ...
Inorganic Surface Engineering to Enhance Perovskite Solar Cell Efficiency
(American Chemical Society, 2017-03-29)
The photoconversion efficiency of perovskite solar cells (PSCs) is enhanced by the deposition of inorganic nanoparticles (NPs) at the interface between the compact TiO2 electron-selective contact and the mesoporous TiO2 ...
Triumphing over Charge Transfer Limitations of PEDOT Nanofiber Reduction Catalyst by 1,2-Ethanedithiol Doping for Quantum Dot Solar Cells
(American Chemical Society, 2017)
Charge transfer between a conducting polymer-based counter electrode (CE) and a polysulfide (S2–/Sn2–) electrolyte mediator is a key limitation to improvements of solar energy conversion efficiency (ECE) in quantum-dot-sensitized ...
Effect of metallacarborane salt H[COSANE] doping on the performance properties of polybenzimidazole membranes for high temperature PEMFCs
(Royal Society of Chemistry, 2020-07-31)
In this paper, a series of composite proton exchange membranes comprising a cobaltacarborane

Molecular relaxation and ionic conductivity of ionic liquids confined in apoly(vinylidenefluoride) polymer matrix: Influence of anion and cation type
(Elsevier, 2019)
Blends of poly(vinylidenefluoride) (PVDF) and ionic liquids (ILs) with different cations and anions have beenprepared by solvent casting. The IL content was the same in all blends of the series. Molecular relaxation andionic ...
Corneal relaxation time estimation as a function of tear oxygen tension in human cornea during contact lens wear
(John Wiley & Sons, 2019-12-03)
The purpose is to estimate the oxygen diffusion coefficient and the relaxation time of the cornea with respect to the oxygen tension at the cornea–tears interface. Both findings are discussed. From the experimental data ...
Interfacial Effects on Dielectric Propertiesof Polymethylmethacrylate-TitaniaMicrocomposites and Nanocomposites
(Wiley, 2017)
It is discussed that dielectric properties of polymethylmethacrylate (PMMA) composites are influenced by the particle size of titania as a result of changes in the structure and dynamics of polymer chains in the interphase ...
Improvement of Photovoltaic Performance of Colloidal Quantum Dot Solar Cells Using Organic Small Molecule as Hole-Selective Layer
(American Chemical Society, 2017-04)
A novel organic small molecule bis-triphenylamine with spiro(fluorene-9,9′-xanthene) as the conjugated system, named BTPA-4, is successfully synthesized and employed as the hole-selective layer (HSL) in colloidal quantum ...
High reduction of interfacial charge recombination in colloidal quantum dot solar cells by metal oxide surface passivation
