Structure and Magnetic Properties of a Series of Uranium Bis-Siloxide Complexes

Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic, Luciano Barluzzi

Despite their synthetic interest and potential attractive properties, the preparation of heteroleptic U(III) complexes containing monodentate ligands remains challenging. Here we report the synthesis, structure and magnetic properties of three heteroleptic ...

Dynamic competition between Cooper pair and spin density wave condensation

Henrik Moodysson Rønnow

Quantum matter phases may coexist microscopically even when they display competing tendencies. A fundamental question is whether such a competition can be avoided through the elimination of one phase while the other one condenses into the ground state. Her ...

Non-equilibrium control of biomolecular condensates

Alexandra Shelest

Biomolecular condensates are cellular organelles without a membrane, which have come into the scientific focus about 15 years ago. They are made from a mix of proteins and RNAs. It is hypothesized that they maintain their shape and function through liquid- ...

Supramolecular Materials from Sustainable Polyesters: Structure, Dynamics, and Performance

Sophia Thiele

The global plastic waste crisis remains a fundamental challenge for mankind to address, as vast amounts of plastic continue to accumulate in the environment, threatening ecosystems and human health. Biobased and biodegradable plastics, particularly materia ...

Tandem Deacetalization−Knoevenagel Condensation Reactions for the Synthesis of Benzylidene Malononitrile Using Ruthenium(II) Cymene Complexes

Paul Joseph Dyson, Farzaneh Fadaei Tirani

In this study, we report the synthesis and full characterization of five novel ruthenium(II) cymene complexes with the general formula [Ru(cym)(L’)Cl], featuring N,O- and N,N-coordinating pyrazolone-based hydrazone ligands. We have characterized these comp ...

Light-Induced 1H NMR Hyperpolarization in Solids at 9.4 and 21.1 T

David Lyndon Emsley, Michael Allan Hope, Federico De Biasi, Máté Visegrádi, Marcel Levien

The inherently low sensitivity of nuclear magnetic resonance (NMR) spectroscopy is the major limiting factor for its application to elucidate structure and dynamics in solids. In the solid state, nuclear spin hyperpolarization methods based on microwave-in ...

Electronic excitations and spin interactions in chromium trihalides from embedded many-body wavefunctions

Oleg Yazyev, Ravi Yadav

Although chromium trihalides are widely regarded as a promising class of two-dimensional magnets for next-generation devices, an accurate description of their electronic structure and magnetic interactions has proven challenging to achieve. Here, we quanti ...

Increasing Precursor Reactivity Enables Continuous Tunability of Copper Nanocrystals from Single-Crystalline to Twinned and Stacking Fault-Lined

Noah Isaac Bussell, Raffaella Buonsanti, Anna Loiudice, Petru Pasquale Albertini, Jari Leemans, Coline Marie Agathe Boulanger, Krishna Kumar, Ludovic Emile Frédy Zaza

Colloidal nanocrystals (NCs) are active materials in different applications, wherein their shape dictates their properties, such as optical or catalytic properties, and, thus, their performance. Hence, learning to tune the NC shape is an important goal in ...

Effect of annealing on flexoelectricity in hafnium oxide (HfO2)

Luis Guillermo Villanueva Torrijo, Daniel Moreno Garcia

Flexoelectricity is universal in all dielectrics, effective at high temperatures, and a promising transduction technique for nanoelectromechanical systems (NEMS). However, as flexoelectricity is still in its early stages, many aspects require further inves ...

Spectroscopic fingerprints of iron-coordinated cobalt and iron porphyrin layers on graphene

Francesco Armillotta

Achieving control in the design of monolayer 2D functional catalysts represents a significant challenge. If that challenge is surmounted, coordinated single-metal-atom sites can offer tailored electronic configuration, ligation geometries, chemical activit ...

Orbital-selective metal skin induced by alkali-metal-dosing Mott-insulating Ca2RuO4

Henrik Moodysson Rønnow, Gianmarco Gatti

Doped Mott insulators are the starting point for interesting physics such as high temperature superconductivity and quantum spin liquids. For multi-band Mott insulators, orbital selective ground states have been envisioned. However, orbital selective metal ...
