A penta-stranded helicate was obtained by combining Pd(CH3CN)42 with La(NO3)3 and a polydentate ligand. The helicate displays low symmetry, both in solution and in the solid state. A dynamic interconversion between the penta-stranded helicate and a ...

Quantification of magic angle spinning dynamic nuclear polarization NMR spectra

David Lyndon Emsley, Pierrick Berruyer, Andrea Bertarello

Dynamic nuclear polarization (DNP) allows to dramatically enhance the sensitivity of magic angle spinning nuclear magnetic resonance (MAS NMR). DNP experiments usually rely on the detection of low-γ nuclei hyperpolarized from 1H with the use of cross polar ...

Carbon dioxide reduction by dinuclear Yb(ii) and Sm(ii) complexes supported by siloxide ligands

Marinella Mazzanti, Farzaneh Fadaei Tirani, Davide Toniolo

Two dinuclear homoleptic complexes of lanthanides(II) supported by the polydentate tris(tertbutoxy) siloxide ligand ([Yb2L4], 1-Yb and [Sm2L4], 1-Sm, (L = (OtBu)3SiO−)) were synthesized in 70–80% yield and 1-Sm was crystallographically characterized. 1-Yb ...

CO2 and CO/H-2 Conversion to Methoxide by a Uranium(IV) Hydride

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone

Here we show that a scaffold combining siloxide ligands and a bridging oxide allows the synthesis and characterization of the stable dinuclear uranium(IV) hydride complex [K-2{U(OSi((OBu)-Bu-t)(3))(3)(mu-O)(mu-H)(2)}], 2, which displays high reductive ...

Fine-tuning the coordination atoms of copper redox mediators: an effective strategy for boosting the photovoltage of dye-sensitized solar cells

Chong Liu, Ulf Anders Hagfeldt, Mei Wang

Natural systems have marvelously utilized copper complexes featuring sulfur-coordinating ligands, known as blue copper proteins, as efficient electron-transfer mediators in biological processes. Copper complexes with sulfur-coordinating ligands have been a ...

A set of microRNAs coordinately controls tumorigenesis, invasion, and metastasis

Douglas Hanahan, Mohammad Sadegh Saghafinia, Iacovos Michael

MicroRNA-mediated gene regulation has been implicated in various diseases, including cancer. This study examined the role of microRNAs (miRNAs) during tumorigenesis and malignant progression of pancreatic neuroendocrine tumors (PanNETs) in a genetically en ...

A tetranuclear samarium(II) inverse sandwich from direct reduction of toluene by a samarium(II) siloxide

Marinella Mazzanti, Farzaneh Fadaei Tirani, Davide Toniolo, Rory Patrick Kelly

The dinuclear SmII complex, [Sm2L4(dme)] (L = OSi(OtBu)3), is easily obtained from the protonolysis reaction of [Sm{N(SiMe3)2}(thf)2] with HOSi(OtBu)3. This complex reacts slowly with toluene, resulting in the isolation of the triple-decker arene-bridged S ...

Highly selective immobilized bimetallic Ni-Au nanoparticle catalyst for the partial hydrogenation of m-dinitrobenzene

Paul Joseph Dyson, Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey, Oliver Anthony Beswick

Transition metal nanoparticles (NPs) are extensively used as catalysts for a wide and diverse range of organic transformations when immobilized on appropriate solid supports. We describe the development of a highly active and highly selective heterogeneous ...
