Optical Amplification in Hollow-Core Negative-Curvature Fibers Doped with Perovskite CsPbBr3 Nanocrystals
(MDPI, 2019)
We report a hollow-core negative-curvature fiber (HC-NCF) optical signal amplifier
fabricated by the filling of the air microchannels of the fiber with all-inorganic CsPbBr3 perovskite
nanocrystals (PNCs). The optimum ...
Perovskite solar cells: a brief introduction and some remarks
(Sociedad Cubana de Física, 2017)
The spectacular and unprecedented rise of so-called perovskite
solar cells (PSCs) in conversion efficiency with low-cost
manufacturing processes has grabbed the attention of the scientific
community ...
Structural and functional insights into the delivery of a bacterial Rhs pore-forming toxin to the membrane
(Nature Research, 2023-11-28)
Bacterial competition is a significant driver of toxin polymorphism, which allows continual compensatory evolution between toxins and the resistance developed to overcome their activity. Bacterial Rearrangement hot spot ...

Ion Transport in Confined Geometries below the Nanoscale: Access Resistance Dominates Protein Channel Conductance in Diluted Solutions
(2017)
Synthetic nanopores and mesoscopic protein channels have common traits like the importance of electrostatic interactions between the permeating ions and the nanochannel. Ion transport at the nanoscale occurs under confinement ...
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 ...
Fluctuation-Driven Transport in Biological Nanopores. A 3D Poisson–Nernst–Planck Study
(MDPI, 2017)
Living systems display a variety of situations in which non-equilibrium fluctuations
couple to certain protein functions yielding astonishing results. Here we study the bacterial channel
OmpF under conditions similar to ...
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 ...
Tunable hysteresis effect for perovskite solar cells
(Royal Society of Chemistry, 2017-09-14)
Perovskite solar cells (PSCs) usually suffer from a hysteresis effect in current–voltage measurements,
which leads to an inaccurate estimation of the device e
fficiency. Although ion migration, charge trapping/
detrapping, ...
Electron trapping induced electrostatic adsorption of cations: a general factor leading to photoactivity decay of nanostructured TiO2
(Royal Society of Chemistry, 2017-02)
In this work, a mechanism of electron trapping induced electrostatic adsorption of electrolyte cations (ETIEA) is proposed to explain the general photoactivity decay of nanostructured TiO2 electrodes, usually occurring ...
