“…Water absorption in wool is significantly affected by the presence of nano TiO 2 on it and photocatalytic decomposition of methylene blue is pronounced due to the TiO 2 embedded in the wool. Other systems include TiO 2 /SiO 2 composite film over cotton fabrics, silicon modified TiO 2 coated wool fibers, aluminum oxide on non-woven and woven fabrics and low temperature processed ZnO nanorod arrays [50][51][52][53][54][55][56][57][58]. Apart from TiO 2 , there is work reported on the use of other oxides such as Al 2 O 3 , ZnO and some nanocomposites [59][60][61][62][63][64].…”

Abstract. Surfaces that exhibit reversible wettability toward water are extremely important for a variety of technological applications. In this context, the development of superhydrophobic and superhydrophilic surfaces for self-cleaning applications has been receiving a great deal of attention in the last few years. In this review, an overview of the current state-of-science and technology of self-cleaning surfaces is presented. The current understanding of physics of wetting leading to surfaces with predictive, controllable and reversible wettability is first presented. The review then focuses on materials, mainly metal oxides and their composites, employed for self-cleaning applications. It is shown that, although conventionally oxides and polymers are considered for self-cleaning applications, recent developments point toward the use of artificially engineered surfaces with hierarchical roughness. Applications of self-cleaning films in nonconventional areas such as protection of fabrics, solar cells and structures related to cultural heritage are discussed. The review ends with an outlook for the future in terms of science and technology of self-cleaning surfaces.

“…The cellulose structures might also react as templates in wet-chemical coating processes such as layer-by-layer deposition. The sol-gel process was used to coat cellulose fibres with photoactive TiO 2 films [28], cellulose nanocrystals with TiO 2 [29] and cellulose nanorod nematic suspensions with SiO 2 , leading to a mesoporous replica upon template removal [30]. We recently reported on the templated formation of silica nanotubes on molecular polysaccharide derivates by polycondensation of silicic acid [31] and sol-gel processing [32], figure 3.…”

The generation of biominerals and hard tissue in nature is directed and templated by biomacromolecules. In many systems, polysaccharides play a significant role during the assembly of the inorganic phase. Polysaccharides exhibit a hierarchical multiscale order as well as self-assembly properties and they appear in a large variety of structures. The directed deposition of inorganic phases on polysaccharide templates is an interesting approach for the manufacturing of patterned functional materials. This paper highlights our recent developments on the bioinspired deposition and formation of inorganic phases on polysaccharide templates. Polysaccharides can be used at various structural levels from the molecular scale to three-dimensional parts in the millimetre range. The versatility of polysaccharide templating capabilities will be shown on onedimensional cellulose nanocrystals for formation of luminescent inorganic nanotubes for optoelectronic applications. The replication of complex plant tissue and processed lignocellulosic materials such as paper and cardboard into carbide based engineering and functional ceramics will be presented. The developed methods for the mineralisation of inorganic phases on polysaccharides are adapted for an innovative bioinspired route involving phototactic microorganisms, which are useful for the light-induced fabrication of hierarchically structured functional materials.

“…Some amazing properties of metals are used in order to improve the photocatalytic activities of semiconductors, such as TiO 2 and SiO 2 , which are among the most efficient ones, resulting in better photocatalytic properties, even under visible rays [5]. Some noble metals, such as Ag [6], Au [7] and Pd [8] have stood the test of time in the field of producing nanocomposites.…”

Titanium dioxide nanoparticles have been used to control corrosion of mild steel in well water in the absence and presence of an aqueous May flower extract. As the concentration of TiO 2 increases, the inhibition efficiency also increases. 100 ppm of TiO 2 offers 84 % inhibition efficiency. The addition of 10mlof May flower extract enhances the inhibition efficiency to 95 %. Adsorption of TiO 2 on the metal surface follows Langmuir adsorption isotherm. Polarization study reveals that the flower extract-TiO 2 system functions as mixed type of inhibitor, controlling both anodic and cathodic reactions. AC impedance spectra reveal the formation of a protective film on the metal surface. This technology may find application in cooling water systems and concrete technology.
