Lewis acid catalyzed [4+2] annulation of bicyclobutanes with dienol ethers for the synthesis of bicyclo[4.1.1]octanes
Bicyclic carbocycles containing a high fraction of Csp3 have become highly attractive synthetic targets because of the multiple applications they have found in medicinal chemistry. The formal cycloaddition of bicyclobutanes (BCBs) with two- or three-atom p ...
Royal Soc Chemistry2024Dynamic nuclear polarisation of 1H in Gd-doped In(OH)3
David Lyndon Emsley, Michael Allan Hope, Yuxuan Zhang, Amrit Venkatesh
Dynamic nuclear polarisation (DNP) of solids doped with high-spin metal ions, such as Gd3+, is a useful strategy to enhance the nuclear magnetic resonance (NMR) sensitivity for these samples. Spin diffusion can relay polarisation throughout a sample, which ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Endogenous O-17 Dynamic Nuclear Polarization of Gd-Doped CeO2 from 100 to 370 K
David Lyndon Emsley, Michael Allan Hope, Moreno Lelli, Snaedis Björgvinsdóttir, Georges Guévork Jean-Jacques Menzildjian, Bowen Zhang, Zhuoran Wang
O-17 NMR is an invaluable tool to study the structure and dynamics of oxide materials but remains challenging to apply in many systems. Even with isotopic enrichment, studies of samples with low masses and/or concentrations of the active species, such as t ...
AMER CHEMICAL SOC2021Design of Ductile Rare-Earth-Free Magnesium Alloys
William Curtin, Binglun Yin, Zhaoxuan Wu, Rasool Ahmad
Pure Mg has low ductility due to a transition of < c+a > pyramidal dislocations to a sessile basal-oriented structure. Dilute alloying generally improves ductility. Enhancement of pyramidal cross-slip from the lower-energy pyramidal II plane to the higher- ...
SPRINGER INTERNATIONAL PUBLISHING AG2020Accessing the plus IV Oxidation State in Molecular Complexes of Praseodymium
Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic
Out of the 14 lanthanide (Ln) ions, molecular complexes of Ln(IV) were known only for cerium and more recently terbium. Here we demonstrate that the +IV oxidation state is also accessible for the large praseodymium (Pr) cation. The oxidation of the tetraki ...
2020Unconventional Spin Relaxation Involving Localized Vibrational Modes in Ho Single-Atom Magnets
Harald Brune, Stefano Rusponi, Marina Pivetta, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Aparajita Singha, Romana Baltic, Katharina Johanna Diller
We investigate the spin relaxation of Ho single atom magnets on MgO/Ag(100) as a function of temperature and magnetic field. We find that the spin relaxation is thermally activated at low field, while it remains larger than 1000 s up to 30 K and 8 T. This ...
AMER PHYSICAL SOC2020Colorimetry of Luminescent Lanthanide Complexes
Anne-Sophie Chauvin, Julien Alexandre Andres
Europium, terbium, dysprosium, and samarium are the main trivalent lanthanide ions emitting in the visible spectrum. In this work, the potential of these ions for colorimetric applications and colour reproduction was studied. The conversion of spectral dat ...
MDPI2020Corrosion behaviour of nitrided ferritic stainless steels for use in solid oxide fuel cell devices
Jan Van Herle, Manuel Bianco, Stéphane François Jean Poitel
Plasma nitriding was applied to ferritic stainless steel substrates to improve their performances as interconnects for solid oxide fuel cell devices. The samples underwent electrical conductivity test and SEM/EDS, TEM/EDS, environmental-SEM analyses. The f ...
2020Effect of oxygen defects blocking barriers on gadolinium doped ceria (GDC) electro-chemo-mechanical properties
Paul Muralt, Robin Nigon, Ahsanul Kabir
Some oxygen defective metal oxides, such as cerium and bismuth oxides, have recently shown exceptional electrostrictive properties that are even superior to the best performing lead-based electrostrictors, e.g. lead-magnesium-niobates (PMN). Compared to pi ...
