Boosting cycling stability through Al(PO) loading in a NaMnV(PO)/C cathode for high-performance sodium-ion batteries.

Mn-based NASICON-type NaMnV(PO) (NMVP) has been widely investigated as one of the most promising alternatives to NaV(PO) cathodes for sodium-ion batteries (SIBs) due to its higher energy density, higher abundance, and lower cost and toxicity compared to V. However, electrochemical performance for large-scale applications is limited by NMVP's inferior conductivity and structural degradation during cycling. Herein, a facile strategy to modify the surface/interphase properties of NMVP/C was reported using the thermally stable Al(PO) precursor with a wet process followed by heat treatment to enhance the interface stability of electrodes.

DNA Interaction, Photocleavage and Topoisomerase I Inhibition by Ru(II) Complex with a New Ligand Possessing Phenazine Unit.

A new ruthenium complex with a dppz-like ligand pyidppz, [Ru(bpy)2(pyidppz)](2+) (pyidppz = 2-(pyridine-2-yl)imidazo-[4,5-b]dipyrido-[3,2-a:2',3'-c]phenazine) has been synthesized and characterized by ES-MS, elemental analysis, (1)H NMR. Intercalative mode of the complex bound to calf thymus DNA has been supported by different spectroscopic methods and viscosity measurements. The introduction of phenazine unit may be one of the main reasons for the weak emission of Ru(II) complex in aqueous solution.

Study on DNA binding behavior and light switch effect of new coumarin-derived Ru(II) complexes.

A new ligand mhcip (mhcip=2-(4-methyl-7-hydroxyl-8-coumarinyl)imidazo[4,5-f]-[1,10]phenanthroline) and its ruthenium complexes, [Ru(L)2mhcip](2+) (L=bpy (2,2'-bipyridine), phen (1,10-phenanthroline)), have been synthesized and characterized. The introduction of coumarin ring may play an important role in the strong fluorescence of the complexes. Intercalative binding mode between both complexes and CT-DNA was determined by UV-visible spectroscopy, fluorescence spectroscopy and viscosity measurements.

Characterization of a functionally active recombinant 1-deoxy-D-xylulose-5-phosphate synthase from Babesia bovis.

The 1-deoxy-D-xylulose-5-phosphate synthase (DXS) enzyme has been characterized in other species, but not in the genus Babesia, which causes major losses in the livestock industries worldwide. Therefore, we isolated, cloned and expressed the wild-type B. bovis dxs cDNA in Escherichia coli and evaluated its enzymatic activity in vitro.

Synthesis, DNA-binding and photocleavage of "light switch" complexes [Ru(bpy)2(pyip)]2+ and [Ru(phen)2(pyip)]2+.

Two novel Ru(II) complexes [Ru(bpy)(2)(pyip)](2+)1 and [Ru(phen)(2)(pyip)](2+)2 (bpy=2,2'-bipyridine; phen=1,10-phenanthroline; pyip=2-(pyridine-2-yl)imidazo-[4,5-f][1,10]-phenanthroline), have been synthesized and characterized by elemental analysis, ES-MS, (1)H NMR, UV-Vis. The DNA-binding behaviors of both complexes were studied by spectroscopic methods and viscosity measurements. The results indicate that the two complexes can bind to CT-DNA in an intercalative mode, and also show that these two Ru(II) complexes can promote the photocleavage of pBR322 DNA.
