Engineering Frustrated Lewis Pair Active Sites in Porous Organic Scaffolds for Catalytic CO2 Hydrogenation
Shubhajit Das, Rubén Laplaza Solanas, Jacob Terence Blaskovits
Frustrated Lewis pairs (FLPs), featuring reactive combinations of Lewis acids and Lewis bases, have been utilized for myriad metal-free homogeneous catalytic processes. Immobilizing the active Lewis sites to a solid support, especially to porous scaffolds, ...
Amer Chemical Soc2024System and method for single cell phenotypical profiling and deterministic nanoliter-droplet encapsulation and deterministic droplet consortia assemblies
Bart Deplancke, Jörn Pezoldt, Johannes Julius Bues
The present invention concerns a system for phenotypical profiling of at least one object and deterministic nanoliter-droplet encapsulation, comprising sample supplying means, buffer supplying means; a microfluidic chip comprising an encapsulation area or ...
2023Enhanced Leaching of Zinc Ferrite by the Formation of a Solid Solution With Magnetite in Hydrochloric Acid Solution
The high zinc and iron contents of electric arc furnace (EAF) dust in the forms of zinc ferrite (ZnFe2O4) and magnetite (Fe3O4) make it a valuable secondary source of these metals. ZnFe2O4 and Fe3O4 are known to form a solid solution at all compositions, a ...
SPRINGER2023Zinc hybrid sintering for printed transient sensors and wireless electronics
Danick Briand, Nicolas Francis Fumeaux
Transient electronics offer a promising solution for reducing electronic waste and for use in implantable bioelectronics, yet their fabrication remains challenging. We report on a scalable method that synergistically combines chemical and photonic mechanis ...
2023Low-Temperature Dynamics of Water Confined in Unidirectional Hydrophilic Zeolite Nanopores
Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno
The dynamical properties of water molecules confinedin the unidirectionalhydrophilic nanopores of AlPO4-54 are investigated withquasi-elastic neutron scattering as a function of temperature downto 118 K. AlPO4-54 has among the largest pores known foralumin ...
AMER CHEMICAL SOC2023Water Orientation at the Anatase TiO2 Nanoparticle Interface: A Probe of Surface pK(a )Values
Arianna Marchioro, Marie Bischoff
The acid-base properties of surfaces significantly influence catalytic and (photo)electrochemical processes. Estimation of acid dissociation constants (pK(a )values) for colloids is commonly performed through electroanalytical techniques or spectroscopic m ...
AMER CHEMICAL SOC2022Recent Advances in Group 14 and 15 Lewis Acids for Frustrated Lewis Pair Chemistry
Frustrated Lewis pairs (FLP) which rely on the cooperative action of Lewis acids and Lewis bases, played a prominent role in the advancement of main-group catalysis. While the early days of FLP chemistry witnessed the dominance of boranes, there is a growi ...

Arianna Marchioro, Marie Bischoff
The acid-base properties of surfaces significantly influence catalytic and (photo)electrochemical processes. Estimation of acid dissociation constants (pKa values) for colloids is commonly performed through electroanalytical techniques or spectroscopic met ...
AMER CHEMICAL SOC2022How Robust Is the Reversible Steric Shielding Strategy for Photoswitchable Organocatalysts?
Simone Gallarati, Raimon Fabregat I De Aguilar-Amat, Veronika Juraskova, Théo Pierre Jaffrelot Inizan
A highly appealing strategy to modulate a catalyst's activity and/or selectivity in a dynamic and noninvasive way is to incorporate a photoresponsive unit into a catalytically competent molecule. However, the description of the photoinduced conformational ...
AMER CHEMICAL SOC2022Acid-base-induced fac → mer isomerization of luminescent iridium(iii) complexes
Kay Severin, Farzaneh Fadaei Tirani, Albert Ruggi, Anastasia Gitlina, Carolina Luciana Plaice
Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...
