Mesoporous titanium dioxide co-doped with boron and lanthanum has been prepared by template method using boric acid triethyl ester, lanthanum nitrate hexahydrate and tetrabutyl titanate as precursors and Pluronic P123 as template. The as-prepared photocatalyst is characterized by thermogravimetric differential thermal analysis, N2 adsorption-desorption measurements, X-ray diffraction, scanning ...

An in situ heparin-based forming hydrogel that cures under visible-light is formulated using eosin Y as a photoinitiator with triethanolamine as an electron donor to initiate reaction of thiolated-heparin with acrylate-ended poly(ethylene glycol). Formulations and irradiation conditions are presented for control of heparin content (1.6 to 3.3% w/v), modulus (100-10,000 Pa), and gelation time (3...

Four hybrid polyoxometalate–porphyrin copolymer films were obtained by the electrooxidation of zinc-β-octaethylporphyrin (ZnOEP) or 5,15-ditolylporphyrin (H2T2P) in presence organosilyl functionalized Keggin-type POMs TBA3[PW11Si2O40C26H16N2] (abbreviated Py-PW11Si2-Py) and Dawson-type TBA6[P2W17Si2O62C26H16N2] Py-P2W17Si2-Py) bearing two remote pyridyl groups. The electropolymerization process...
