The family of anticancer complexes that include the transition metal copper known as Casiopeínas® shows promising results. Two of these complexes are currently in clinical trials. The interaction of these compounds with DNA has been observed experimentally and several hypotheses regarding the mechanism of action have been developed, and these include the generation of reactive oxygen species, p...

We compare the accuracy of conventional semilocal density functional theory DFT , the DFT+U method, and the Heyd-Scuseria-Ernzerhof HSE06 hybrid functional for structural parameters, redox reaction energies, and formation energies of transition metal compounds. Conventional DFT functionals significantly underestimate redox potentials for these compounds. Zhou et al. Phys. Rev. B 70, 235121 2004...

The key to develop earth-abundant energy storage technologies sodium- and potassium-ion batteries (SIBs PIBs) is identify low-cost electrode materials that allow fast reversible Na+/K+ intercalation. Here, we report an intercalation-type material TiNb24O62 as a versatile anode for SIBs PIBs, via synergistic strategy of oxygen vacancy carbon incorporation enhance ion electron diffusion. TiNb24O6...

Kaolinite (K), a polar and layered aluminosilicate mineral, was used as the host; ethanolamine (EOA) and ethylene glycol (EG) were inserted into the kaolinite interlayer to give the intercalated supramolecular compounds kaolinite-ethanolamine (K-EOA) and kaolinite-ethylene glycol (K-EG), respectively. The intercalation of EOA and EG resulted in an increase in the d(001)-value by 3.4 and 3.68 Å,...

The reduction of tungsten hexachloride with lead powder was investigated by differential scanning calorimetry (DSC) combined with X-ray diffraction (XRD) studies. Intermediate compounds along the way of the reduction of W6+ to W2+ were detected, prepared by solid-state synthesis, and structurally characterized by X-ray diffraction techniques. Five new compounds, namely Pb0.5WCl6, PbW2Cl10, Pb1....
