The structure of iodine monochloride (ICl) intercalated into graphite (GIC) has been revisited, and a stage 1 stoichiometry about 10 carbon atoms to ICl molecule is determined. Intercalation proceeds readily at room temperature without additional energy input. A chainlike alternating halogen species proposed for the intercalation layer based on detailed Raman spectroscopic analysis ab initio ca...

Significant progress has been achieved in the research on sodium intercalation compounds as positive electrode materials for Na-ion batteries. This paper presents an overview of the breakthroughs in the past decade for developing high energy and high power cathode materials. Two major classes, layered oxides and polyanion compounds, are covered. Their electrochemical performance and the related...

The RNA genomes of a number of pathogenic RNA viruses, such as HIV-1, have extensive folded conformations with imperfect A-form duplexes that are essential for virus function and could serve as targets for structure-specific antiviral drugs. As an initial step in the discovery of such drugs, the interactions with RNA of a wide variety of compounds, which are known to bind to DNA in the minor gr...

Three groups of doxorubicin and daunorubicin analogues, differing by their substituents on the chromophore and sugar moieties, were used in this study. The 3'-A'-unsubstituted (Group I), 3'-/V-acyl (Group 2), and .V-,V-alkyl (Group 3) analogues were tested for: (a) in vivo antitumor activity and in vitro cytotoxicity; (b) cellular or tissue uptake and meta bolic conversion; (c) strength of DNA ...

Flavonoids and other polyphenolic compounds have been shown to inhibit human topoisomerase IB (topo I) through both inhibition of relaxation activity and through stabilization of the cleavable complex (poisoning). Some flavonoids have also been shown to intercalate DNA, and an association of topoisomerase inhibition with intercalation has been noted. We surveyed 34 polyphenolic compounds, prima...

Tetraalkylammonium salts have larger ions than metal ions, which can greatly change the interlayer space and energy, and then potentially tune the properties of graphite. In this work, various graphite intercalation compounds (GICs) have been synthesized by intercalating tetraoctylammonium bromide (TOAB) ions into graphite through electrochemical interactions under different reduction potential...
