Use of Graphite as a Highly Reversible Electrode with Superior Cycle Life for Sodium-Ion Batteries by Making Use of Co-Intercalation Phenomena

Use of Graphite as a Highly Reversible Electrode with Superior Cycle Life for Sodium-Ion Batteries by Making Use of Co-Intercalation Phenomena

In contrast to the general view, graphite can be used as an electrode material in sodium-ion batteries by taking advantage of the formation of ternary graphite intercalation compounds. The important features of this electrode reaction are the small irreversible capacity, the low overpotentials, and the superior cycle life. With a capacity close to 100 mAh g−1, the electrode is attractive for stationary applications.

A Practical Approach for the Oxidation of Unactivated Csp3-H Bonds with o-Nitro(diacetoxyiodo)benzene as an Efficient Hypervalent Iodine(III)-Based Oxidizing Agent

A bit hyper: A practical approach for the oxidation of unactivated Csp3-H bonds by o-nitro(diacetoxyiodo)benzene is presented. The nitro group coordinates to the adjacent iodine center through dipolar interaction, which leads to a single substitution of the acetate ligand by tert-butyl hydroperoxide (TBHP). As a result, a strong iodanyl radical is formed, which can activate the inert Csp3-H bonds in a highly efficient manner.

Better than ‘Super’: Compounds that elicit cytoprotective and anti-inflammatory effects are promising candidates for chemoprevention. Analogues of 1-methyl-3-(2-oxopropylidene)indolin-2-one (‘supercinnamaldehyde’) were synthesized and evaluated for their ability to induce Nrf2-mediated cytoprotection and suppress NF-κB-directed inflammation. Lead compound 6 (R1: Me; R2: Ph), with the supercinnamaldehyde scaffold, has the potential to yield derivatives with even greater chemopreventive activity.

Alkenyl-Alkynylgermanes Functionalised by Lewis Acids: Intramolecular Aluminium– and Gallium–Alkyne Interactions and Potential Ge–C Bond Activation

Alkenyl-Alkynylgermanes Functionalised by Lewis Acids: Intramolecular Aluminium– and Gallium–Alkyne Interactions and Potential Ge–C Bond Activation

Bond activation by intramolecular interactions of alkynyl carbon with highly Lewis acidic aluminium atoms was observed for functionalised alkenyl-alkynylgermanes. Such mixed germanium–aluminum or –gallium compounds were obtained by hydrometallation of dialkynylgermanes and are promising candidates for secondary reactions such as cyclisation or insertion.

Trinuclear [CoIII2–LnIII] (Ln=Tb, Dy) Single-Ion Magnets with Mixed 6-Chloro-2-Hydroxypyridine and Schiff Base Ligands

Trinuclear [CoIII2–LnIII] (Ln=Tb, Dy) Single-Ion Magnets with Mixed 6-Chloro-2-Hydroxypyridine and Schiff Base Ligands

SIM-ply the best! A new type of 3d–4f single-ion magnet (SIM) with a diamagnetic cobalt(III) ion as the 3d metal is constructed. The large steric hindrance of the cobalt(III) segments in the SIM minimize the number of intermolecular magnetic interactions, and because of the presence of mononuclear LnIII magnetic systems, the magnetic anisotropy can be easily modified, which results in remarkable anisotropic barriers.

Electrically Controlled Eight-Spin-Qubit Entangled-State Generation in a Molecular Break Junction

Electrically Controlled Eight-Spin-Qubit Entangled-State Generation in a Molecular Break Junction

Tale of entanglement: An eight-spin-qubit quantum entangled state can be realized in a dinuclear Fe(II) complex which (under a specific set of quantum-logic-gate operations) can act as a source of multi-qubit generation. The large decoherence time with high quantum fidelity factor makes the system an efficient quantum-computing object.

Insight into the Recognition, Binding, and Reactivity of Catalytic Metallodrugs Targeting Stem Loop IIb of Hepatitis C IRES RNA

Insight into the Recognition, Binding, and Reactivity of Catalytic Metallodrugs Targeting Stem Loop IIb of Hepatitis C IRES RNA

Metal with mettle: Catalytic metallodrugs are a new compound class with potential for high therapeutic activity and low toxicity. The Cu-GGHYrFK-amide complex was reported earlier to catalytically inactivate stem loop IIb of the HCV internal ribosomal entry site RNA, and to show significant antiviral activity in a cellular HCV replicon assay. Herein we describe our studies focused on understanding the cleavage mechanism and the relationship of catalyst configuration to structural recognition and site-selective cleavage of the structured RNA motif.
