Separating bulk and surface processes in NiOx electrocatalysts for water oxidation
(Royal Society of Chemistry, 2020-08-10)
Nickel oxide-based catalysts currently represent the state of the art in electrochemical water oxidation in alkaline pH. However, much of their functionality remains poorly understood, particularly regarding catalytically ...
Methylammonium Lead Bromide Perovskite Battery Anodes Reversibly Host High Li-Ion Concentrations
(American Chemical Society, 2017-04)
Ions migrate through the hybrid halide perovskite lattice, allowing for a variety of electrochemical applications as perovskite-based electrodes for batteries. It is still unknown how extrinsic defects such as lithium ions ...
Boosting Long-Term Stability of Pure Formamidinium Perovskite Solar Cells by Ambient Air Additive Assisted Fabrication
(American Chemical Society, 2021-09-13)
Due to the high industrial interest for perovskite-based photovoltaic devices, there is an urgent need to fabricate them under ambient atmosphere, not limited to low relative humidity (RH) conditions. The formamidinium ...
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 ...
Gold(I) Metallo‐Tweezers for the Recognition of Functionalized Polycyclic Aromatic Hydrocarbons by Combined π–π Stacking and H‐Bonding
(Wiley, 2017)
Two gold(I)‐based metallo‐tweezers with bis(Au−NHC) pincers and a carbazole connector have been obtained and used for the recognition of polycyclic aromatic hydrocarbons (PAHs). In the case of the tweezer with pyrene–NHC ...
Cation-Driven Self-Assembly of a Gold(I)-Based Metallo-Tweezer
(Wiley, 2017-08-07)
A combination of self-complementary pi-pi-stacking interactions and metallophilic interactions triggered the self-assembly of a new digold(I) metallo-tweezer in the presence of several types of M+ ions. Titrations by ...
Categorical Variable Mapping Considerations in Classification Problems: Protein Application
(MDPI, 2023)
The mapping of categorical variables into numerical values is common in machine learning
classification problems. This type of mapping is frequently performed in a relatively arbitrary manner.
We present a series of four ...
Comparison between Trion and Exciton Electronic Properties in CdSe and PbS Nanoplatelets
(American Chemical Society, 2021-07-07)
The optoelectronic properties of metal chalcogenide
colloidal nanoplatelets are often interpreted in terms of excitonic
states. However, recent spectroscopic experiments evidence the
presence of trion states, enabled ...
Stability of dye-sensitized solar cells under extended thermal stress
(Royal Society of Chemistry, 2017)
In the last few decades, dye-sensitized solar cell (DSC) technology has been demonstrated to be a promising
candidate for low cost energy production due to cost-effective materials and fabrication processes. Arguably,
DSC ...
Platinum-Based Organometallic Folders for the Recognition of Electron-Deficient Aromatic Substrates
(Wiley, 2017-05-29)
A series of platinum complexes with cis-oriented polyaromatic N-heterocyclic carbene ligands were prepared and characterized. The relative disposition of the polyaromatic ligands about the metal cause these compounds to ...
