The capillary rise technique has been used to experimentally study the “surface tension” of liquid marbles formed by encapsulating water droplets with polytetrafluoroethylene (PTFE) powder of 1, 35, and 100 μm particle size. In a typical experiment, a glass capillary tube was inserted into a water marble to measure the capillary rise of the water. The Laplace pressure exerted by the water marbl...

Background and purpose: Taguchi method is a powerful design in experimental studies. This method, with the minimum number of test factors affecting the process, will save cost and time. This study was done using the Taguchi method to optimize the adsorption of fluoride from aqueous solutions by an adsorbent prepared from marble powder. Material and methods: Marble powder was supplied from Hama...

This paper investigates the friction coefficient of a moving liquid marble, a small liquid droplet coated with hydrophobic powder and floating on another liquid surface. A floating marble can easily move across water surface due to the low friction, allowing for the transport of aqueous solutions with minimal energy input. However, the motion of a floating marble has yet to be systematically ch...

Liquid marbles are micro reservoirs of fluid surrounded by a powder shell. Their unique properties show promise for high-value technological applications in the medical, biotechnology, chemical and pharmaceutical industries. In this study, liquid marbles were prepared from six mixtures of water and glycerol by releasing droplets from different heights onto a loosely packed powder bed using a 1m...

Ionic liquids (ILs)-stabilized iron oxide (Fe(2)O(3)) nanoparticles were synthesized by the ultrasonic decomposition of iron carbonyl precursors in [EMIm][BF(4)] without any stabilizing or capping agents. The Fe(2)O(3) nanoparticles were isolated and characterized by X-ray powder diffraction, transmission electron microscopy and susceptibility measurements. The physicochemical properties of ILs...

Background and Objective: Finding a low-cost adsorbent as well as discovering a simple modification technique to increase the efficiency of adsorbent for the removal of environmental pollutants is always important. Therefore, this study aimed to evaluate the effectiveness of the calcination to increase the efficiency of raw marble powder in the removal of Acid Orange 7 dye from aqueous solu...
