Synthesis and Characterization of Functionalized Spacer Cations for the Incorporation in Layered Perovskites

Layered hybrid organic-inorganic perovskite (LHOIP) materials are an emerging class of semiconductors endorsed as a more stable alternative compared to the more widely investigated 3D hybrid organic-inorganic halide perovskites (HOIP). Consisting of altern ...

Integrated Aerodynamic/Electrochemical Microsystem for Collection and Detection of Nanogram-level Airborne Bioaccessible Metals

Jian Wang, Christian Ludwig, Tianyu Cen, Jiukai Tang

The soluble fraction of aerosol particulate matter containing trace metals has the potential to engender toxicity and exacerbate the adverse health effects of particulate matter. In this study, an inertial-impaction-based fluidic chip integrated with elect ...

Tuning Napththalenediimide Cations for Incorporation into Ruddlesden–Popper-Type Hybrid Perovskites

Jacques-Edouard Moser, Kevin Sivula, Jun Ho Yum, Simon Nussbaum, Liang Yao, Etienne Christophe Socie

Layered hybrid organic−inorganic perovskite (LHOIP) materials constructed with low-band-gap chromophore-based organic spacer cations are anemerging class of materials that promise unique tunability of their optoelectronic properties. However, the large siz ...

A Strategy to Conjugate Bioactive Fragments to Cytotoxic Diiron Bis(cyclopentadienyl) Complexes

Paul Joseph Dyson, Mouna Hadiji, Silvia Schoch, Sarah Alexandra Pais Pereira

A series of bioactive molecules were synthesized from the condensation of aspirin or chlorambucil with terminal alkynes bearing alcohol or amine substituents. Insertion of the resulting alkynes into the iron-carbyne bond of readily accessible diiron bis(cy ...

Surface Reconstruction Engineering with Synergistic Effect of Mixed‐Salt Passivation Treatment toward Efficient and Stable Perovskite Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Yeonju Kim, Ulf Anders Hagfeldt, Filippo de Angelis, Hui-Seon Kim, Bowen Yang, Jiajia Suo

Surface passivation treatment is a widely used strategy to resolve trap-mediated nonradiative recombination toward high-efficiency metal-halide perovskite photovoltaics. However, a lack of passivation with mixture treatment has been investigated, as well a ...

Hybrid multiple-site mass closure and source apportionment of PM2.5 and aerosol acidity at major cities in the Po Valley

Athanasios Nenes, Spyros Pandis

This study investigates the major chemical components, particle-bound water content, acidity (pH), and major potential sources of PM2.5 in major cities (Belluno, Conegliano, Vicenza, Mestre, Padua, and Rovigo) in the eastern end of the Po Valley. The measu ...

Potential bioavailability of inorganic compounds from Tire and Road Wear Particles to fish in simulated gastric and intestinal fluids

Florian Frédéric Vincent Breider, Benoît Jean Dominique Ferrari, Thibault Béranger Masset

The potential impact of Tire and Road Wear Particles (TRWP) on aquatic organisms has recently gained attention since the occurrence of TRWP in the aquatic environment has been demonstrated in surface water and sediments of numerous regions. However, data r ...

A smart low molecular weight gelator for the triple detection of copper (II), mercury (II), and cyanide ions in water resources

Rosario Scopelliti

Novel supramolecular gelators based on quinoline-indolin-2-one structure were synthesized. These gelators formed stable organogels in a mixture of DMSO/H2O (1:1). The scanning electron microscopy (SEM), IR and NMR spectroscopies, and rheological measuremen ...

Heterogeneous catalyst preparation by liquid-phase atomic layer deposition

Benjamin Pierre Le Monnier

Heterogeneous catalyst preparation has been performed for close to a century but has been rapidly evolving spurred by the evolution in synthetic techniques and growing needs in energy, chemicals and materials. An increasing number of catalyst synthesis str ...
