Pinning and depinning of Wenzel-state droplets around inclined steps
Publication date: March 2020Source: Colloid and Interface Science Communications, Volume 35Author(s): Umut Ceyhan, Aslı Tiktaş, Mert ÖzdoğanAbstractDroplets moving over inclined heterogenous substrates may pin around rough spots. A simplified model of one of these spots having a backward facing step geometry over a chemically homogeneous inclined substrate reveals that the step is responsible from the pinning-depinning of the leading edge of the droplet in Wenzel-state. We consider a two-dimensional partially wetting droplet and model its motion by the evolution equation with a precursor film model. The phase diagrams ...

Two types of liquid marbles are formed by coating the dry mixture test material on pendant or sessile drops. The silver nanowire particles are separated from the graphite or talcum shell by entering into the liquid core of the marbles. The liquid core is extracted into capi...

Water adsorption and antibacterial activity studies for characterization of Ca-LTA zeolite/diatomite adsorbents
In this study, Ca-LTA Zeolite-diatomite-based adsorbents with purified diatomite loading rates of 15, 20 and 25 wt% are investigated by physicochemical, thermal and antibacterial characterizations. X-ray diffraction and FTIR spectroscopy analyses show that the purified diatomite is homogeneously dispersed into the Ca-LTA zeolite and that the zeolite crystalline structure is preserved. All analyses indicate that porous volumes, specific surface areas and initial water adsorption rates are affected by the mesoporosity nature of diatomite. Based on the water TPD profiles, the variation of the activation energy (Ea) and entha...

On the nature of colloidal aphrons
Publication date: January 2020Source: Colloid and Interface Science Communications, Volume 34Author(s): Yong-li Yan, Yang Zhang, Christian-chibuike UnaAbstractColloidal gas (liquid) aphrons (CGAs/CLAs) were originally proposed by professor Sebba to be unique and intriguing systems with structure different from general foams or emulsions. As a consequence of their fascinating colloidal properties, a number of investigators have exploited various industrial applications. However, the nature especially the interfacial structure of this colloidal dispersion is still disputed by many researchers. Here we demonstrate the differe...
