This research aims to develop asphalt mixtures with new capabilities, namely photocatalytic, superhydrophobic, and self-cleaning capabilities. Different solutions were prepared combining nano-TiO 2 micro-PTFE on water, ethyl alcohol, dimethyl ketone different concentrations. The sprayed over the mixtures, photocatalytic superhydrophobic capabilities evaluated via decolourization of Rhodamine B ...

Hydrophobic surfaces and coatings have attracted more interest in recent years due to their broad applications diverse areas. In many cases, a metallic surface would demonstrate reversible wettability from hydrophilic state hydrophobic spontaneously. However, the wetting behavior mechanism of are far clear. this work, 304 stainless steel (SS) Ni–Cu–P been chosen investigate intrinsic transition...

The facile, simple, highly efficient, and fluorine-free fabrication of superhydrophobic surfaces on fabrics with high durability has attracted considerable attention because its urgent practical application. simple dip-coating method was adopted to make a stable durable polydimethylsiloxane/stearic acid/silica (PDMS/STA/SiO2) fabric. fabric’s surface morphology, roughness, composition were anal...

The Internet has tremendous amount of information to be readily gathered and mined. But lack of useful tools for gathering and mining information makes the information under-utilized. Also, it would be very nice if an individual could have his own information gathering and filtering system so that he can freely tweak information according to his own needs. But building and maintaining a reliabl...

We study the adsorption of a symmetric triblock copolymer of ethylene oxide, EO, and propylene oxide, PO, end-capped with quarternized poly(2-dimethylaminoethyl methacrylate), DMAEMA (DMAEMA(24)-EO(132)PO(50)EO(132)-DMAEMA(24)). Light scattering and tensiometry are used to measure the relative size of the associated structures and surface excess at the air-liquid interface. The adsorbed amount,...

Aim We present a model to account for self-assembly of the slough–ridge–tree island patterned landscape of the central Everglades in southern Florida via feedbacks among landforms, hydrology, vegetation and biogeochemistry. We test aspects of this model by analysing vegetation composition in relation to local and landscape-level drivers. Location We quantified vegetation composition and environ...

The development of materials with hydrophobic properties has been widely explored in areas such as textiles, healthcare, sports, and personal protective equipment. Hydrophobic that arise from nanoparticles (nPs) directly promote other valuable properties, including self-cleaning capabilities, decreased bacterial growth, increased comfort. In this study, biodegradable poly(?-caprolactone) (PCL) ...
