The Fate of Cycloruthenated Compounds: From C–H Activation to Innovative Anticancer Therapy

23 gennaio, 2017 - 00:00

 From C–H Activation to Innovative Anticancer Therapy

Cycloruthenated compounds have been shown to be amazingly stable and exciting anticancer drug candidates featuring original modes of action. The role of the C–Ru bond that is intramolecularly stabilized by dative bonds is highlighted, because the cytotoxicity of these compounds is often up to two or three orders of magnitude higher than that of structurally related species lacking the C–Ru bond.

Cell and Cell-Free Mechanistic Studies on Two Gold(III) Complexes with Proven Antitumor Properties

23 gennaio, 2017 - 00:00

Cell and Cell‐Free Mechanistic Studies on Two Gold(III) Complexes with Proven Antitumor Properties

Two Au–dithiocarbamato complexes are promising anticancer agents. Spectrometric studies revealed different patterns of interaction with HSA and ctDNA as model biomolecules, likely due to differences in redox chemistry. One complex was tested against A549 lung carcinoma cells using an xCELLigence Real-Time Cell Analysis system; measures of impedance by non-invasive Au microelectrodes showed that the complex inhibits cell proliferation after only 4 h.

Large Magnetic Anisotropy in Linear Co<sup>II</sup> Complexes – Ab Initio Investigation of the Roles of Ligand Field, Structural Distortion, and Conformational Dynamics

23 gennaio, 2017 - 00:00

Large Magnetic Anisotropy in Linear CoII Complexes – Ab Initio Investigation of the Roles of Ligand Field, Structural Distortion, and Conformational Dynamics

Linear CoII complexes with varying ligand-field strengths exhibit large effective barriers for magnetic anisotropy (up to 974 cm–1). Ab initio calculations reveal the effects of the steric crowding around the metal center, ligand-field strength, structural distortion, and conformational changes on the magnetic anisotropy barrier and, in particular, the mechanism of relaxation of magnetic moments.

Selective Extraction of Americium(III) over Europium(III) Ions with Pyridylpyrazole Ligands: Structure–Property Relationships

23 gennaio, 2017 - 00:00

 Structure–Property Relationships

The steric effects of the branched chains of a series of alkyl-substituted pyridylpyrazole ligands on the extraction of AmIII and EuIII ions were investigated in HNO3 medium. These ligands exhibit good selective extraction abilities for AmIII ions, and the steric effects of the branched chain have a significant impact on the distribution ratios (DAm and DEu) and the separation factor (SFAm/Eu).

Selective Hydrogenation of Nitriles to Primary Amines by using a Cobalt Phosphine Catalyst

Cobalt catalyzes it: A general procedure for the selective hydrogenation of (hetero)aromatic or aliphatic nitriles catalyzed by a cobalt-based system is described. A wide range of primary amines are synthesized in 61–99 % yield. Use of the tetradentate ligand tris[2-(dicyclohexylphosphino)ethyl]phosphine is key for the activity of the system.

Palladium(II)-Catalysed Aminocarbonylation of Terminal Alkynes for the Synthesis of 2-Ynamides: Addressing the Challenges of Solvents and Gas Mixtures

23 gennaio, 2017 - 00:00

 Addressing the Challenges of Solvents and Gas Mixtures

Safe and sound: The synthesis of 2-ynamides is possible through oxidative carbonylation catalysed by ligand-free PdII in low loadings. High yields are obtained with a variety of alkynes and amines, and the need to rely on dangerous solvents such as 1,4-dioxane is eliminated by the use of [NBu4]I, which allows the utilisation of the industrially recommended solvent ethyl acetate. O2 can be used as the terminal oxidant, and the catalyst can operate under safer conditions with low O2 concentrations.

Covalent Surface Modification of Gallium Arsenide Photocathodes for Water Splitting in Highly Acidic Electrolyte

23 gennaio, 2017 - 00:00

Covalent Surface Modification of Gallium Arsenide Photocathodes for Water Splitting in Highly Acidic Electrolyte

Tunable, stable photoelectrodes: Covalent binding of fluorinated aryl groups to the surface of gallium arsenide (GaAs(1 0 0)) photocathodes shifts the onset potential for proton reduction by nearly 150 mV and results in electrodes that exhibit stable long-term performance in highly acidic (pH<0) electrolyte.

Metal–Organic Coaxial Nanowire Array Electrodes Combining Large Energy Capacity and High Rate Capability

Inside the wire: Metal–organic coaxial nanowire array electrodes exhibit a large capacity of 62.2 mF cm−2 and 11.6 F cm−3 at a fast charge/discharge rate of 5080 mA cm−3. The design of the nanowire electrodes imparts excellent rate capability to pseudocapacitors, and their energy density can be increased to a maximum value while maintaining a high-level power density.

Influence of Binders and Solvents on Stability of Ru/RuO<sub><i>x</i></sub> Nanoparticles on ITO Nanocrystals as Li–O<sub>2</sub> Battery Cathodes

23 gennaio, 2017 - 00:00

Influence of Binders and Solvents on Stability of Ru/RuOx Nanoparticles on ITO Nanocrystals as Li–O2 Battery Cathodes

Building better batteries: Indium tin oxide (ITO) nanocrystals with supported 1–2 nm Ru/RuOx nanoparticles (NPs) demonstrate efficient oxygen evolution reaction (OER) processes for Li–O2 battery cathodes. The Ru/RuOx NPs are most effective in DMSO electrolytes with a carboxymethyl cellulose (CMC) binder. ITO is found to be unstable from the first cycle and the Ru/RuOx NPs remain effective OER catalysts for efficient Li2O2 during cycling.

Identifying and Understanding Strong Vibronic Interaction Effects Observed in the Asymmetry of Chiral Molecule Photoelectron Angular Distributions

23 gennaio, 2017 - 00:00

Identifying and Understanding Strong Vibronic Interaction Effects Observed in the Asymmetry of Chiral Molecule Photoelectron Angular Distributions

Emerging chiral research direction? Photoionization of randomly oriented methyloxirane and trifluoromethyloxirane enantiomers by circularly polarized light leads to emission of photoelectrons in preferred directions. This chiral asymmetry is observed by using velocity map imaging photoelectron circular dichroism (background example). New studies demonstrate that the angular distributions are radically modified, and even reversed, when weak vibrational modes are excited in the ion.

Large‐Scale Quantum Many‐Body Perturbation on Spin and Charge Separation in the Excited States of the Synthesized Donor–Acceptor Hybrid PBI–Macrocycle Complex

The reliable calculation of the excited states of charge-transfer compounds poses a major challenge to the ab initio community. By applying the highly sophisticated many-body perturbation approach, the authors address the inconsistencies found by using standard time-dependent density functional theory.

Separation of Anti‐Phase Signals Due to Parahydrogen Induced Polarization via 2D Nutation NMR Spectroscopy

Hydrogenation: Two-dimensional nutation NMR experiments are demonstrated to be suitable for separating anti-phase 1H NMR signals caused by parahydrogen induced polarization (PHIP). The pairwise incorporation of parahydrogen into propene is investigated on platinum-containing silica using in situ 1H MAS NMR spectroscopy under continuous-flow conditions.

Theoretical Evaluation of Terahertz Sources Generated From SnGa4Q7 (Q=S, Se) as Infrared Nonlinear Optical Materials

So good it hertz: The infrared nonlinear optical crystals SnGa4Q7 (Q=S, Se) are evaluated as terahertz (THz) sources on the basis of a difference frequency generation process. Specifically, we find that a large nonlinear susceptibility or a large figure of merit results in large efficiency of the THz source. Furthermore, THz absorption reduces the efficiency of the THz source for the two materials.
