Interface inductive currents and carrier injection in hybrid perovskite single crystals
(AIP Publishing, 2017-10)
nterfaces between the absorbing perovskite and transporting layers are gaining attention as the key locus that governs solar cell operation and long term performance. The interplay of ionic and electronic processes, along ...
Viroporins: A new target for fighting viral infections
(SBE - Sociedad de Biofísica de España, 2017)
Over the last years an increasing number of viruses have jumped into the mass media and several
names or acronyms (Ebola, zika, SARS, MERS,…) have become familiar to the general public because of the high mortality rates ...
Direct retrieval method of the effective permittivity and permeability of bulk semi-infinite metamaterials by variable-angle spectroscopic ellipsometry
(OSA Publishing, 2019)
In this work, we present a simple method for the direct retrieval of the effective
permittivity and permeability of a bulk semi-infinite metamaterial from variable-angle spectroscopic ellipsometry measurements. Starting ...
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 ...
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 ...
Suppressing H2 Evolution and Promoting Selective CO2 Electroreduction to CO at Low Overpotentials by Alloying Au with Pd
(2019-03-11)
CO2 electroreduction is a promising technology to produce chemicals and fuels from renewable resources. Polycrystalline and nanostructured metals have been tested extensively while less effort has been spent on understanding ...
Counterbalance between Surface and Confinement Effects As Studied for Amino-Terminated Poly(propylene glycol) Constraint in Silica Nanopores
(American Chemical Society, 2019)
Broadband dielectric spectroscopy (BDS) and orthopositronium annihilation lifetime spectroscopy (PALS) are combined to study the
molecular dynamics and the free volume of poly(propylene glycol) terminated
with amino end ...
Valley Hall phases in kagome lattices
(American Physical Society, 2019)
We report the finding of the analogous valley Hall effect in phononic systems arising from mirror symmetry
breaking, in addition to spatial inversion symmetry breaking. We study topological phases of plates and
spring-mass ...
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 ...
Inhibition of light emission from the metastable tetragonal phase at low temperatures in island-like films of lead iodide perovskites
(Royal Society of Chemistry, 2019)
Photonic applications based on halide perovskites, namely CH3NH3PbI3 (MAPbI3), have recently attracted
remarkable attention due to the high efficiencies reported for photovoltaic and light emitting devices.
Despite these ...
