Single-walled carbon nanotubes (SWNTs) are currently the focus of extensive interdisciplinary studies because of their unique physical and chemical properties and potential electronic applications, for example, in making sensors and fieldemission devices. Processing of SWNT-based materials into engineered macroscopic materials is still in its infancy; the most successful methods so far have bee...

Our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (Nano-CS), for the first time. The second objective was to compare and contrast such penetrations to those of chitosan (CS) itself, as well as sodium hypochlorite (NaOCl), chlorhexidine (CHX) and ethylenediamintetraacetic acid (EDTA), at the routinely used concentrations. Molar roots were split l...

Wide used technique of patterning surfaces with solid particles utilizes the evaporation of colloidal droplets from a substrate. In particular, evaporation of liquid samples is a key problem in the development of microarray technology (including labs-on-a chip), especially in the case of open reactors [1]. A plenty of works are devoted to the evaporation of the sessile droplets [2–5]. One assum...

Water infiltration into granular soils and the associated pore water pressure increase reduction in shear strength can trigger landslides, instability of vertical cuts failure retaining walls. Water-repellent reduce to maintain soil suction. Recent research has demonstrated creation synthetic water-repellent using chemical methods. This paper investigates a biological treatment for creating san...

Cyclic olefin copolymer (COC) is a novel type of thermoplastic polymer gaining the attention scientific community in electronic, optoelectronic, biomedicine and packaging applications. Despite benefits use COC such as undoubted optical transparency, chemical stability, good water–vapor barrier biocompatibility, its original hydrophobicity restricts wider applicability optimization performances....

Nanoflower is anticipated to become a very smart material due its unique properties such as high surface volume ratio. A hydrothermal method was used in this study prepare the zinc oxide (ZnO) nanoflower and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) Fourier transform infrared spectroscopy (FT-IR). The average particle size of ZnO calculated 21nm according Deby...

This paper deals with investigation of changes in geopolymer wettability increasing mass fraction high-carbon fly ash and surface treatment by cold atmospheric plasma (CAP) to determine the influence on whether it is a viable method increase for further treatment. In this study, multiple samples geopolymers were prepared, including those 16% 32% from coal-fired power station. Wettability was th...

The shape of a sessile drop on horizontal substrate depends upon the Bond number $Bo$ and contact angle $\alpha$ . Inspired by puddle approximations at large (Quéré, Rep. Prog. Phys. , vol. 68, 2005, p. 2495), we address here limit small angles fixed volume arbitrary It readily leads to pancake approximation, where height radius scale as $\alpha ^{-1/2}$ respectively, with capillary forces bein...
