The complexes of some 2-spirothiazolid-4-one derivatives have been prepared with Cu(II), N i(II), Co(II) and Cd(II) salts. The complexes all have a metal to ligand ratios of 1:1 or 1:2 and are all believed to have tetrahedral structures with chelating ligands. Their structures are suggested on the basis of analysis, X-ray diffraction techniques, spectral (UV-VIS, IR, XH NM R), and thermal decom...

Economic and powerful olefins separation is the most important technology for the energy optimisation and reduction of fossil fuel in petrochemical industry. On account of that the specific structures of olefins will make some influences on the separation, in this work, by means of density functional theory, we perform a theoretical estimation of the olefin-structure-induced effects on the reac...

The efficiency of photodynamic therapy is limited mainly due to low selectivity, unfavorable biodistribution of photosensitizers, and long-lasting skin sensitivity to light. However, drug delivery systems based on nanoparticles may overcome the limitations mentioned above. Among others, dendrimers are particularly attractive as carriers, because of their globular architecture and high loading c...

Most studies of the organic complexation of Cu in natural waters have focused on distributions and processes in the water column, where a significant fraction of Cu-complexing ligands may be biologically produced. We present direct evidence for a flux of Cu-complexing ligands from estuarine sediments, demonstrating that sediments are a significant, yet previously unrecognized source of the liga...
