“…It follows from the results presented in Figure 8 that, after 20 minutes of exposure, the intensity of the band decreases by 80%. Similar results [24] have been reported for thin-layer structures of TiO 2 and SiO 2 obtained by the LbL technique. An equal decomposition ratio was achieved for thicker structures and longer irradiation time: 120 layers and 60 min correspondingly.…”

Layer-by-layer (LbL) synthesis of titanium dioxide was performed by an oxidation-reduction route using a Ti(OH)3colloid and NaNO2solutions. A model of chemical reactions was proposed based on the results of an investigation of synthesized nanolayers by scanning electron microscopy, electron microprobe analysis and X-ray photoelectron spectroscopy, and studying colloidal solution of Ti(OH)3with laser Doppler microelectrophoresis. At each cycle, negatively charged colloidal particles of[Ti(OH)3]HSO4-adsorbed onto the surface of substrate. During the next stage of treatment in NaNO2solution, the particles were oxidized to Ti(OH)4. Photocatalytic activity was studied by following decomposition of methylene blue (MB) under UV irradiation. Sensitivity of the measurements was increased using a diffuse transmittance (DT) method. The investigation revealed strong photocatalytical properties of the synthesized layers, caused by their high area per unit volume and uniform globular structure.

“…Photocatalytical properties of titanium dioxide layers synthesized on the surface of grinded quartz were studied applying standard method [24], which is based on analysis of degradation under UV irradiation of methylene blue adsorbed on the substrate. General characteristics of MB are presented in Table 1.…”

“… 142 Another method to alter the behavior of a typical TiO 2 thin film is the use of bilayers (ie, closely packed double layers of molecules). For example, Lin et al 143 used 120 bilayers to obtain a photocatalytic surface under visible light. However, the mechanical integrity is often poor due to the absence of polyelectrolytes that glue the multilayers together.…”

“…However, the mechanical integrity is often poor due to the absence of polyelectrolytes that glue the multilayers together. 143 Furthermore, hydrophilic surfaces can be created with nanostructures through microelectromechanical system (MEMS) fabrication techniques. Verma et al 144 observed that the WCA decreased with an increase in nanostructure height and thus surface roughness.…”

Review of Techniques to Achieve Optical Surface Cleanliness and Their Potential Application to Surgical Endoscopes

A clear visualization of the operative field is of critical importance in endoscopic surgery. During surgery the endoscope lens can get fouled by body fluids (eg, blood), ground substance, rinsing fluid, bone dust, or smoke plumes, resulting in visual impairment. As a result, surgeons spend part of the procedure on intermittent cleaning of the endoscope lens. Current cleaning methods that rely on manual wiping or a lens irrigation system are still far from ideal, leading to longer procedure times, dirtying of the surgical site, and reduced visual acuity, potentially reducing patient safety. With the goal of finding a solution to these issues, a literature review was conducted to identify and categorize existing techniques capable of achieving optically clean surfaces, and to show which techniques can potentially be implemented in surgical practice. The review found that the most promising method for achieving surface cleanliness consists of a hybrid solution, namely, that of a hydrophilic or hydrophobic coating on the endoscope lens and the use of the existing lens irrigation system.

“…However in some cases, a self-cleaning effect has been reported for superhydrophilic surfaces, like for TiO2-based compounds [12]. Self-cleaning property of TiO2 has been investigated by many authors and has been found to be also related to its photo-catalytic property [13,14]. Thanks to its superhydrophilicity, dusts and organic contaminants formed by UV decomposition of oils… etc.…”

Sputtered Ag thin films with modified morphologies: Influence on wetting property

Silver thin films with thickness ranging from 3 nm to 33 nm were sputter deposited onto silicon wafers and tungsten layers. Those W layers were previously synthesized in the same DC magnetron sputter deposition system with various experimental conditions (argon pressure, target to substrate distance) in order to stabilize different surface morphologies. SEM observations and AFM images showed that the growth mode of Ag films is similar on Si substrates and on the smoothest W layers, whereas it is modified for rough W layers made of sharp grains. The effect of the W layer morphology on Ag film growth was clearly evidenced when the deposition took place at high temperature. It is seen that performing the deposition onto substrates of various morphologies allows to tailor the wetting property of the Ag deposit.
