Protein phosphorylation controls many cellular processes and activities. One of the major challenges in the proteomic study of phosphorylation is the enrichment of substoichiometric phosphorylated peptides from complex mixtures. Titanium dioxide (TiO2)-based chromatography is now widely applied to isolate phosphopeptides because of its efficiency and flexibility. In this study, a novel TiO2 coa...

In recent years, dye-sensitized solar cells (DSSCs) based on nanocrystalline mesoporous TiO2 films have attracted much attention as a potential low-cost alternative to single or polycrystalline p–n junction silicon solar cells. DSSCs can reach electrical energy conversion efficiencies ≈12% [154, 284]. The traditional mesoporous TiO2 electrode composed of the TiO2 nanoparticles offer insufficien...

mesoporous tio2 has been prepared using a nonionic block copolymer (pluronic p-123) as structure-directing agent with sol-gel method. characterization of the product was carried out by means of x-ray diffraction (xrd), scanning electron microscopy (sem), thermogravimetry-differential scanning calorimetry (tg-dsc), nitrogen sorption isotherms, and uv-vis absorption spectroscopy. these analyses s...

A single-molecule microscopy study of the interaction dye-modified alkanes, alkenes, and alkynes with nanostructured catalysts based on TiO2 reveals significant differences in desorption kinetics probe molecules depending chemical nature catalyst. comparison materials decorated palladium (Pd@TiO2) or molybdenum/cobalt (MoCo@TiO2) kinetic that part justify better performance MoCo@TiO2 semihydrog...

In this article, we have proposed a nanostructured photovoltaic device based on the ZnO nanostructures/poly(3-hexylthiophene)(P3HT):TiO2 nanorod hybrid by solution processes at low temperature. An array of ZnO nanorods with a larger size of y50 nm in diameter and y180 nm in length are grown to provide direct pathways for efficient charge collection. TiO2 nanorods with a size of y5 nm in diamete...

Photocatalytic ceramic membranes have attracted considerable attention for industrial wastewater treatment. However, morphological control of the membrane surface to improve its photocatalytic reactivity for the degradation of organic pollutants remains a challenge. Herein, we report a new nanostructured TiO2/Al2O3 composite ceramic membrane prepared from a poly(oxyethylene methacrylate) (POEM)...

A novel design has been proposed for a facile and rapid build-up of highly tailorable nanostructured multishells on metal oxide particles (graphene/TiOx@TiO2) under dry inert atmosphere to maximize the visible-light photocatalytic performance. We also thoroughly systematically investigated as-prepared particle surface mechanisms extraordinary in-situ graphene growth TiOx@TiO2 nanoparticles achi...

a  commercial  ti-nanoxide  was  deposited  on  in-doped  sno2 (ito) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (dsscs).  ruthenium  dye  was adsorbed on each tio2 film for 24 h. the resulting photoelectrodes were used to form flexible dsscs in combination with elec...
