The porous structure is the result of aggregation-induced particle formation. The inherent fluorescence is assigned to coordinatively unsaturated Zr4+ ions at the sol{\textendash}{}gel derived ZrO2 surface. After physico-chemical characterization of the native zirconia particles carboxyl and/or amine bearing drug molecules (D,L-\ensuremath{\alpha}-difluoromethylornithine {\textendash}{} DFMO, ursolic acid {\textendash}{} UA and doxorubicin {\textendash}{} DOX) were adsorbed onto their surface, and the products were analyzed with Fourier-transform infrared spectroscopy (FTIR), thermogravimetry (TG), small-angle X-ray scattering (SAXS), fluorimetry and zeta potential vs. pH measurements. We have found that DOX complexes coordinatively unsaturated Zr4+ ions without dislocating them, while carboxyl-bearing drugs interact with basic surface Zr{\textendash}{}OH sites eliminating some of the carbonate species. The adsorption of UA at the zirconia surface shifts considerably the isoelectric point of the surface and thus provides kinetic stability to the particles at physiological pH.

Wacker type supported Pd/VOx/SBA-15 catalysts were obtained by introducing Pd into VOx/SBA-15 samples using conventional impregnation method. The activity of the catalysts was tested in the gas phase partial oxidation of ethylene by O2 in the presence of H2O (Wacker oxidation). VOx/SBA-15 sample was obtained by micelle-templated synthesis using vanadium-containing synthesis gel. The vanadium became incorporated in the silica structure from the gel in near to atomic dispersion. This catalyst was quite active in ethylene oxidation to CO2 but had low Wacker activity. Isolated, polymeric and bulk vanadia species were identified in the VOx/SBA-15 prepared by wet impregnation/calcination method. The specific surface area of the sample was found to be smaller than that of the neat SBA-15 support because some pores were blocked by vanadia agglomerates. The corresponding Pd/VOx/SBA-15 catalyst showed high selectivity for acetaldehyde formation but the activity was relatively low due to low accessible active surface. A third VOx/SBA-15 sample was obtained by applying directed surface reaction between silanol groups of dehydrated SBA-15 and anhydrous solution of vanadyl acetylacetonate. Large number of accessible Pd/VOx sites were present in the corresponding Pd/VOx/SBA-15 catalyst. Latter catalyst induced ethylene oxidation to acetaldehyde with high yield at temperatures <=160~{\textdegree}C and with good yield to acetic acid at temperatures >=160~{\textdegree}C.}, keywords = {H2-TPR, Pd/V catalysts, SBA-15, UV{\textendash}Vis, Wacker oxidation}, isbn = {1387-1811}, url = {http://www.sciencedirect.com/science/article/pii/S1387181115000050}, author = {Barthos, R{\'o}bert and Hegyessy, Andr{\'a}s and Kl{\'e}bert, Szilvia and Valyon, J{\'o}zsef} } @article {125, title = {Effect of metal oxide on surface area and pore size of water-dispersible colloids from three {German} silt loam topsoils}, journal = {Geoderma}, volume = {235-236}, year = {2014}, pages = {260{\textendash}270}, keywords = {CREDO}, issn = {00167061}, doi = {10.1016/j.geoderma.2014.07.017}, url = {http://linkinghub.elsevier.com/retrieve/pii/S0016706114002882}, author = {Jiang, Canlan and S{\'e}quaris, Jean-Marie and Andr{\'a}s Wacha and B{\'o}ta, Attila and Vereecken, Harry and Klumpp, Erwin} } @article {104, title = {Mechanical Stability and Fibrinolytic Resistance of Clots Containing Fibrin, DNA, and Histones}, journal = {Journal of Biological ChemistryJournal of Biological Chemistry}, volume = {288}, year = {2013}, month = {03/08/2013}, pages = {6946-6956}, abstract = {

Neutrophil extracellular traps are networks of DNA and associated proteins produced by nucleosome release from activated neutrophils in response to infection stimuli and have recently been identified as key mediators between innate immunity, inflammation, and hemostasis. The interaction of DNA and histones with a number of hemostatic factors has been shown to promote clotting and is associated with increased thrombosis, but little is known about the effects of DNA and histones on the regulation of fibrin stability and fibrinolysis. Here we demonstrate that the addition of histone-DNA complexes to fibrin results in thicker fibers (increase in median diameter from 84 to 123 nm according to scanning electron microscopy data) accompanied by improved stability and rigidity (the critical shear stress causing loss of fibrin viscosity increases from 150 to 376 Pa whereas the storage modulus of the gel increases from 62 to 82 pascals according to oscillation rheometric data). The effects of DNA and histones alone are subtle and suggest that histones affect clot structure whereas DNA changes the way clots are lysed. The combination of histones + DNA significantly prolongs clot lysis. Isothermal titration and confocal microscopy studies suggest that histones and DNA bind large fibrin degradation products with 191 and 136 nm dissociation constants, respectively, interactions that inhibit clot lysis. Heparin, which is known to interfere with the formation of neutrophil extracellular traps, appears to prolong lysis time at a concentration favoring ternary histone-DNA-heparin complex formation, and DNase effectively promotes clot lysis in combination with tissue plasminogen activator.
