With millions of years of natural evolution, organisms have achieved sophisticated structures, patterns or textures with complex, spontaneous multifunctionality. Among all the fascinating characteristics observed in biosystems, self-cleaning ability is regarded as one of the most interesting topics in biomimicry because of its potential applications in various fields such as aerospace, energy c...

Advanced coatings are essential to modern technologies as they optimise surface characteristics for different application scenarios. Transparent and self-cleaning increasingly used protective various applications, such foldable touchscreens, windows, solar panels. Moreover, incorporating other functionalities high hardness, wear resistance, flexibility into transparent is important broadening t...

In this work, two electrically conductive samples based on polypyrrole (PPy) and (PPy/TiO2) were synthesized via mini-emulsion polymerization. Synthesized used as functional fillers to formulate different screen-printing pastes (pastes A B) obtain the multi-purpose printed films with excellent properties, including electrical conductivity, antibacterial, photocatalytic activity, self-cleaning. ...

Background Social support and school play a pivotal role in the development of oral health-related behaviors among students. This study was conducted to determine the relationship between stages of dental cleaning behavior change based on Trans-theoretical model with school role and social support in Iranian students. Materials and Methods In a cross-sectional study, 525 male and female student...

Many methods have been reported to improving the photocatalytic efficiency of organic pollutant and their reliable applications. In this work, we propose a facile pathway to prepare three different types of magnetic iron oxides/TiO2 hybrid nanoparticles (NPs) by seed-mediated method. The hybrid NPs are composed of spindle, hollow, and ultrafine iron oxide NPs as seeds and 3-aminopropyltriethylo...

The exceptionally adhesive foot of the gecko remains clean in dirty environments by shedding contaminants with each step. Synthetic gecko-inspired adhesives have achieved similar attachment strengths to the gecko on smooth surfaces, but the process of contact self-cleaning has yet to be effectively demonstrated. Here, we present the first gecko-inspired adhesive that has matched both the attach...

Tungsten trioxide (WO₃) nanorods are synthesized on the surface of graphene (GR) sheets by using a one-step in-situ hydrothermal method employing sodium tungstate (Na₂WO₄·2H₂O) and graphene oxide (GO) as precursors. The resulting WO₃/GR nanocomposites are characterized by X-ray diffraction, Raman spectroscopy, transmission electron microscopy, scanning electron microscopy and X-ray photoelectro...

An indoor air purification technique, which combines unipolar ion emission and photocatalytic oxidation (promoted by a specially designed RCI cell), was investigated in two test chambers, 2.75 m3 and 24.3 m3, using nonbiological and biological challenge aerosols. The reduction in particle concentration was measured size selectively in real-time, and the Air Cleaning Factor and the Clean Air Del...
