The role of oxygen vacancies in water splitting photoanodes
(Royal Society of Chemistry, 2020-12-01)
Photoelectrochemical water splitting has become one of the most reliable solar-energy conversion
technologies for clean hydrogen production. In the race of developing and understanding new
semiconducting materials for ...
Buried Interface Passivation of Perovskite Solar Cells by Atomic Layer Deposition of Al2O3
(American Chemical Society, 2023-04-14)
Despite having long excited carrier lifetimes and high mobilities in hybrid halide perovskite materials, conventional (n-i-p) devices exhibit significant interfacial nonradiative recombination losses that are little ...
Unraveling a Biomass-Derived Multiphase Catalyst for the Dehydrogenative Coupling of Silanes with Alcohols under Aerobic Conditions
(American Chemical Society, 2021)
Herein, a novel silver and chromium nanostructured N-doped carbonaceous material has been synthesized by a biomass-annealing approach using readily available chitosan as a raw material. The resulting catalyst AgCr@CN-800 ...
Chemi-Structural Stabilization of Formamidinium Lead Iodide Perovskite by Using Embedded Quantum Dots
(American Chemical Society, 2020-01-6)
The approaches to stabilize the perovskite structure of formamidinium lead iodide (FAPI) commonly result in a blue shift of the band gap, which limits the maximum photoconversion efficiency. Here, we report the use of PbS ...
Catalyst design for highly efficient carbon dioxide hydrogenation to formic acid under buffering conditions
(Elsevier, 2020-03-19)
We report on new ruthenium complexes as catalysts for the efficient transformation of CO2 into formic acid employing basic ionic liquids as buffering media. Remarkably, these complexes catalyze the hydrogenation of CO2 ...
A QM/MM study on the origin of retro-aldolase activity of a catalytic antibody
(The Royal Society of Chemistry, 2021-04-26)
The retro-aldolase mechanism of methodol catalysed by the catalytic antibody 33F12 is described based on the exploration of the free energy landscape obtained with QM/MM methods. The amino acids involved in the reaction ...
Two-Component Peptidic Molecular Gels for Topical Drug Delivery of Naproxen
(American Chemical Society, 2021-01-05)
Transdermal drug delivery (TDD) is an advantageous and effective approach for the localized delivery of drugs; however, overcoming the high impermeability of the outermost layer of skin, the stratum corneum, represents a ...
Shape-Adaptability and Redox-Switching Properties of a Di-Gold Metallotweezer
(WileyAsian Chemical Editorial Society (ACES)ChemPubSoc Europe, 2021-04-12)
The use of a carbazolyl-connected di-gold(I) metallotweezer for the encapsulation of several electron-poor organic substrates, and a planar Au(III) complex containing a CNC pincer ligand, is described. The binding affinity ...
Ultrafast loss of lattice coherence in the light-induced structural phase transition of V2 O3
(American Physical Society, 2022-12-12)
In solids, the response of the lattice to photoexcitation is often described by the inertial evolution on an impulsively modified potential energy surface which leads to coherent motion. However, it remains unknown if ...
Assessing the Drawbacks and Benefits of Ion Migration in Lead Halide Perovskites
(American Chemical Society, 2022-10-14)
Since the inception of the unprecedented rise of halide perovskites for photovoltaic research, ion migration has shadowed this material class with undesirable hysteresis and degradation effects, limiting its practical ...
