Due to the dynamic nature and low stoichiometry of protein phosphorylation, enrichment of phosphorylated peptides from proteolytic mixtures is often necessary prior to their characterization by mass spectrometry. Several phosphopeptide isolation strategies have been presented in the literature, including immobilized metal ion affinity chromatography. However, that technique suffers from poor se...

titanium dioxide is one kind of important materials, which has been extensively investigated because of its unique electronic and optical properties. a large number of efforts have been made to synthesize tio2 materials with different methods. in this review paper, we summarize the synthesis pathways, morphology, as well as crystallization of the nanostructured tio2. in addition, we also mentio...

Titanium dioxide (TiO2) is one of the most widely studied photocatalysts during the past decades due to its ability to photo-oxidize harmful chemicals in both air and water to CO2 in the presence of UV light. TiO2 also shows promise for energy applications such as water splitting [1], as well as in photochemical solar cells [2]. TiO2 use has also been extended to large scale commercial producti...

The conditions for photocatalytic degradation of ethylenediaminetetraacetic acid (EDTA) in aqueous solution with Fe-doped titanium dioxide (TiO2) were optimized. The degradation efficiencies with Fe-doped TiO2 were better, compared with those obtained with bare TiO2 and Pt-doped TiO2. The effect of various experimental factors, such as photocatalytic dosage, temperature, solution pH and light i...

A new type of nonstoichiometric rutile titanium dioxide (TiO2) film with around 15 at% oxygen vacancies homogeneously distributed throughout the bulk was prepared. The resultant films, when used as a photoelectrode, showed a photoelectrochemical water splitting activity 1.7 times that of stoichiometric TiO2 at a bias of 0.9 V vs. Ag/AgCl. This is believed to result from the synergistic effect o...

It is well known that clinical bleaching can be achieved with a solution of 30% hydrogen peroxide (H2O2) or H2O2/titanium dioxide (TiO2) combination. This study examined the hypothesis that TiO2 coated with hydroxyapatite (HAp-TiO2) can generate reactive oxygen species (ROS). ROS are generated via photocatalysis using electron spin resonance (ESR). The bleaching properties of HAp-TiO2 in the pr...

Columns packed with microsized titanium dioxide particles have been used effectively as precolumns for enriching phosphopeptides from complex mixtures. Nanosized titanium dioxide particles have a higher specific surface area and, hence, potentially higher trapping capacities toward phosphopeptides than do microsized particles. Thus, in this study, we employed TiO2-coated magnetic (Fe3O4/TiO2 co...

Selective synthesis of titanium dioxide (TiO2) polymorphs including anatase, rutile, brookite and TiO2(B) by solvothermal treatment of water-soluble titanium complexes is described with a special focus on their morphological control. The utilization of watersoluble titanium complexes as a raw material allowed us to employ various additives in the synthesis of TiO2. As a result, the selective sy...
