Metal-Stabilized Boronate Ester Cages
Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Erica Giraldi
Molecular cages with arylboronate ester caps at the vertices are described. The cages were obtained by metal-templated polycondensation reactions of a tris(2-formylpyridine oxime) ligand with arylboronic acids. Suited templates are triflate or triflimide s ...
2021Shape retaining self-healing metal-coordinated hydrogels
Esther Amstad, Alvaro Lino Boris Charlet, Raffaele Mezzenga
Metal-coordinated hydrogels are physical hydrogels entirely crosslinked by complexes between ligand decorated polymers and metal ions. The mechanical properties of these hydrogels strongly depend on the density and dynamics of metal-coordinated interaction ...
2021Color-tunable emitter material
Berend Smit, Fatmah Ebrahim, Christopher Patrick Ireland
The invention is directed to a color-tunable emitter material comprising a crystal containing complexes of luminescent biomolecule-based ligands and metal ions and to a method for preparing the color-tunable emitter material. Furthermore, the invention rel ...
2021Oxygen evolution reaction catalyzed by first-row transition metal oxides: stability and mechanism
Water splitting offers the opportunity for storing solar energy and, thus, producing carbon-neutral and renewable solar fuels. The process, known as artificial photosynthesis, is limited by the electrocatalytic conversion of water into molecular oxygen. El ...
EPFL2020Structure-Property Relationships of Microphase-Separated Metallosupramolecular Polymers
The structural, thermomechanical, and viscoelastic properties of metallosupramolecular polymers (MSPs) can be controlled through the choice of the multiligand monomer and the nature of the metal salt from which these materials are assembled. This versatili ...
AMER CHEMICAL SOC2020Development of a novel carboxamide-based off-on switch fluorescence sensor: Hg2+, Zn(2+)and Cd2+
Here, the carboxamide ligandN-(thiazole-2-yl) picolinamide (L) was synthesized in an ionic liquid tetrabutylammonium bromide (TBAB) as the benign reaction medium. The sensitivity ofLtowards different metal-ions was investigated, and a comprehensive, logica ...
2020Stability profiles of transition metal oxides in the oxygen evolution reaction in alkaline medium
The electrochemical water splitting reaction can convert renewable electricity into clean hydrogen fuel. The efficiency of water splitting is limited to a large extent by the sluggish oxygen evolution reaction (OER). Numerous transition metal oxides have b ...
ROYAL SOC CHEMISTRY2019Contaminant loading and competitive access of Pb, Zn and Mn(III) to vacancy sites in biogenic MnO2
Louise Helene Soegaard Jensen, Jasquelin Peña
The scavenging properties of MnO2 are largely attributed to sorption on layer vacancy sites. However, co-occurrence of Mn(II, III) with MnO2 can change mineral reactivity by modifying its Mn(III) content or number of free vacancy sites. These processes are ...
2018Zabinskiite, ideally Ca(Al0.5Ta0.5)(SiO4)O, a new mineral of the titanite group from the Pilawa Gorna pegmatite, the Gory Sowie Block, southwestern Poland
Zabinskiite, ideally Ca(Al0.5Ta0.5)(SiO4) O, was found in a Variscan granitic pegmatite at Pilawa Gorna, Lower Silesia, SW Poland. The mineral occurs along with (Al, Ta, Nb)-and (Al, F)-bearing titanites, a pyrochlore-supergroup mineral and a K-mica in co ...
2017Vertical changes of the Co and Mn speciation along a lateritic regolith developed on peridotites (New Caledonia)
Gabrielle Dublet, Vincent Noel
Because they can host significant amounts of Co, the Mn-oxides are commonly considered as the major Co-bearing mineral species in lateritic environments. However, little is known about the process leading to the formation and/or the weathering of these Co- ...
