Innovative nanostructured treatments for stone conservation, based on dispersions of photoactive TiO2 nanoparticles, recently studied in our research group, provided interesting results after laboratory testing. Unfortunately, it is almost impossible to accurately reproduce in the lab the complexity of field exposure conditions. It is then of crucial importance to evaluate the behaviour and dur...

Infections caused by microorganisms are a global public health problem that continually demands new antimicrobial strategies. The generation of reactive oxygen species (ROS) photocatalytic materials is an attractive approach to combat microbes. Along these lines, titanium dioxide (TiO2) constitutes outstanding light-driven ROS generator. However, the wide bandgap this semiconductor limits its u...

The process of removing indium ions from aqueous solutions by applying capacitive deionization (CDI) is reported in this manuscript. First, a modified carbon material was prepared incorporating titanium dioxide (TiO2) into activated (AC). A microwave-assisted ionothermal synthesis (MAIS) method used to produce evenly distributed nanostructured anatase TiO2 on the surface AC. polyurethane (PU) e...

Adv. Mater. 2010, 22, 2329–2332 2010 WILEY-VCH Verlag G Since the advent of dye-sensitized solar cells (DSCs), which have achieved 11% of power conversion efficiency (PCE) in TiO2-based photoelectrodes, a lot of efforts have been devoted to make low-cost, light-weight, high-performance photovoltaic devices. Nanostructured metal oxides are one of key factors in determining the PCE of DSCs, becau...

We report the use of nanostructured TiO2 (NST) as porous cellular adhesion interfaces for microsystems. Integrated NST films and pad arrays with sponge-like morphology were fabricated by aqueous oxidation of Ti films followed by thermal annealing. Cell culture studies indicate significantly (t < 0.02 from the student’s t-test) greater initial attachment of mouse fibroblast cells on porous NST t...

Nanostructured titanium compounds have recently been applied in the design of gas sensors. Among compounds, oxides (TiO2) are most frequently used sensing devices. Therefore, this review, we paying significant attention to variety allotropic modifications oxides, which include anatase, rutile, brukite. Very recently, applicability non-stoichiometric oxide (TiO2−x)-based layers for sensors was d...

Semiconductor photocatalysts have important applications in the fields of renewable energy and environmental remediation. Of these, TiO2 stands out as one of the most investigated compounds in contemporary material science. Because of its unique physical and chemical properties, TiO2 is extensively used in photoelectrochemical applications including photocatalysis and photovoltaics. In this Rev...
