Spontaneous motion of liquid droplets can occur on hydrophobic, micro-structured, solid surfaces comprising a structural gradient. In this study, we examine such experimentally and explain our observations by invoking variable droplet–surface interactions (both actuation resistance forces) arising from the The oscillatory droplet constitutes an integral aspect behaviour is incorporated into ove...

The equilibrium contact angle of a droplet resting on solid substrate can reveal essential properties the solid's surface. However, when motion surface shows significant hysteresis, it is generally accepted that cannot be determined. Here, we describe method to measure tensions soft solids with strong wetting hysteresis. With independent knowledge tension fluid and linear-elastic response solid...

The aim of this research work was the evaluation feasibility to utilize industrial by-products, such as electric arc furnace steel slags, for sustainable concrete production. paper evaluated environmental and mechanical properties slags concrete, respectively. Specifically, release contaminants from investigated by leaching test fresh hardened were a mixture designed with partial substitution (...

Let W be a finite or an affine Coxeter group and Wc the set of all the fully commutative elements in W . For any left cell L of W containing some fully commutative element, our main result of the paper is to prove that there exists a unique element (say wL) in L ∩ Wc such that any z ∈ L has the form z = xwL with `(z) = `(x) + `(wL) for some x ∈ W . This implies that L is left connected, verifyi...

conclusions in conclusion, the suspension containing veegum 1%, sodium carboxy methyl cellulose 1%, glycerine 0.2%, sodium citrate 0.3% and sorbitol 20 % was chosen as the most physically stable formulation. results according to the results, glycerin (0.2%) and sodium citrate (0.3%) had the best effect on the suspension stability as wetting and flocculating agents, respectively. rheological pro...
