OBJECTIVE Western lifestyle and diet are major environmental factors playing a role in the development of IBD. Titanium dioxide (TiO2) nanoparticles are widely used as food additives or in pharmaceutical formulations and are consumed by millions of people on a daily basis. We investigated the effects of TiO2 in the development of colitis and the role of the nucleotide-binding oligomerisation do...

TiO2 nanostructures, including nanowires, highly ordered nanotube arrays, and single crystalline nanoplates, were obtained from electrochemically anodized Ti foil in a fluorine-containing ethylene glycol electrolyte. The TiO2 nanowires, formed by the electric field induced chemical splitting of TiO2 nanotubes by fluoride ions during a lengthy anodization can be isolated from the nanotube arrays...

TiO2 nanotube arrays on the surface of dental implants were fabricated by two-step anodic oxidation. Their effects on bone-implant contact were researched by a pilot in vivo study. The implants were classified into four groups. An implant group with TiO2 nanotube arrays and recombinant human bone morphogenetic protein-2 (rhBMP-2) was compared with various surface implants, including machined su...

Two different nanosized TiO2-based catalysts supported onto glass with tailored photocatalytic properties upon irradiation by UV light were successfully employed for the degradation of nalidixid acid, a widely diffused antibacterial agent of environmental relevance known to be non-biodegradable. Anatase rod-like TiO2 nanocrystals (TiO2NRs) and a semiconductor oxide-noble metal nanocomposite TiO...

The chemical bonding of particulate photocatalysts to supporting material surfaces is of great importance in engineering more efficient and practical photocatalytic structures. However, the influence of such chemical bonding on the optical and surface properties of the photocatalyst and thus its photocatalytic activity/reaction selectivity behavior has not been systematically studied. In this i...

Recently, two types of TiO2 nanotube arrays (NTAs) (blue- and black-colored TiO2 NTAs), which are easily fabricated by electrochemical self-doping, have gained much attention due particularly to their enhanced capacitive and oxidant-generating properties. These enhanced electrochemical properties mean that they have potential as basic materials for energy and environmental applications, such as...

Resumen. Se analizan las implicaciones que la posible sustitución de las tradicionales publicaciones científicas impresas por sus equivalentes electrónicas puede tener en el proceso de comunicación científica. En primer lugar se examinan las dos grandes ventajas que han favorecido el crecimiento de las publicaciones electrónicas y que afectan a las comunidades bibliotecaria y científica: las re...

Remarks: Neat Na-LAS was 16.1 % (w/w) active C11.6 LAS in an aqueous solution, average molecular weight = 342 g/mol; Ca-LAS was > 99 % active C11.6 LAS (crystalline), average molecular weight = 674 g/mol (Ca is bivalent and therefore, each Ca atom has 2 LAS molecules); Mg-LAS 94 % active C11.6 LAS (crystalline), average molecular weight = 658 g/mol (Mg is bivalent and therefore, each Mg atom ha...

There are currently great needs to develop low-cost inorganic materials that can efficiently perform solar water splitting as photoelectrolysis of water into hydrogen and oxygen has significant potential to provide clean energy. We investigate the Si/TiO2 nanowire heterostructures to determine their potential for the photooxidation of water. We observed that highly dense Si/TiO2 core/shell nano...
