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, ...
Big dynorphin is a neuroprotector scaffold against amyloid β-peptide aggregation and cell toxicity
(Elsevier, 2022)
Amyloid β-peptide (Aβ) misfolding into β-sheet structures triggers neurotoxicity inducing Alzheimer’s disease (AD). Molecules able to reduce or to impair Aβ aggregation are highly relevant as possible AD treatments since ...
Diffraction-Based Phase Calibration of Spatial Light Modulators With Binary Phase Fresnel Lenses
(IEEE, 2016)
We propose a simple and robust method to determine the calibration function of phase-only spatial light modulators (SLMs). The proposed method is based on the codification of binary phase Fresnel lenses (BPFLs) onto an ...
Molecular Characterization of the Viroporin Function of Foot-and-Mouth Disease Virus Nonstructural Protein 2B
(American Society for Microbiology, 2018-12)
Nonstructural protein 2B of foot-and-mouth disease (FMD) virus (FMDV) is comprised of a small, hydrophobic, 154-amino-acid protein. Structure-function analyses demonstrated that FMDV 2B is an ion channel-forming protein. ...
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 ...
The P. aeruginosa effector Tse5 forms membrane pores disrupting the membrane potential of intoxicated bacteria
(Nature Research, 2022)
The type VI secretion system (T6SS) of Pseudomonas aeruginosa injects effector proteins into neighbouring competitors and host cells, providing a fitness advantage that allows this opportunistic nosocomial pathogen to ...
Lead-Free Perovskite Solar Cells

Visualizing time: how linguistic metaphors are incorporated into displaying instruments in the process of interpreting time-varying signals
(2017)
Spatial visualization is a well-established topic of education research that has allowed improving science and engineering students’ skills on spatial relations. Connections have been established between visualization as ...
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 ...
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 ...
