Removing Instability-Caused Low-Frequency Features in Small Perturbation Spectra of Perovskite Solar Cells
(American Chemical Society, 2020-06-29)
Small-perturbation frequency-domain techniques such as impedance spectroscopy and intensity-modulated photocurrent spectroscopy (IMPS) have become important methods for the investigation of the physical working mechanisms ...
Complex shaping of the depth of focus
(Optical Society of America, 2020)
In this manuscript an exact solution to the inverse problem of axial beam shaping along the focus of a convergent lens is found. This allows to extend, within the framework of the scalar theory of diffraction, the mathematical ...
State of the Art and Prospects for Halide Perovskite Nanocrystals
(American Chemical Society, 2021-06-17)
Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics ...
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 ...
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 ...
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 ...
Biphasic concentration patterns in ionic transport under nanoconfinement revealed in steady-state and time-dependent properties
(American Institute of Physics, 2023-02-08)
Ion permeation across nanoscopic structures differs considerably from microfluidics because of strong steric constraints, transformed solvent properties, and charge-regulation effects revealed mostly in diluted solutions. ...
Nanocomposition of PEDOT:PSS with metal phthalocyanines as promising hole transport layers for organic photovoltaics
(Elsevier, 2023)
PEDOT:PSS is one of the most widely used materials as a hole selective layer in organic photovoltaics due to its
easy processing and high reproducibility. Unfortunately, the material is limited when testing new ...
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
protonated H[Co(C2B9H11)2] named (H[COSANE]) and polybenzimidazole (PBI) for a high temperature
proton exchange membrane fuel ...
Inactivation of SARS-CoV-2 by a chitosan/α-Ag2WO4 composite generated by femtosecond laser irradiation
(Nature Research, 2022)
In the current COVID‑19 pandemic, the next generation of innovative materials with enhanced anti‑
SARS‑CoV‑2 activity is urgently needed to prevent the spread of this virus within the community.
Herein, we report the ...
