Underwater superoleophobic graphene oxide coated meshes for the separation of oil and water.
Hydrophilic graphene oxide (GO) nanosheets can be easily coated onto stainless steel meshes. Compared to neat meshes, GO coated meshes become more hydrophilic in air and superoleophobic under water. Taking advantage of this completely opposite wettability, GO coated meshes were used for gravity-driven oil-water separation.
متن کاملA self-cleaning underwater superoleophobic mesh for oil-water separation
Oil-water separation has recently become a global challenging task because of the frequent occurrence of oil spill accidents due to the offshore oil production and transportation, and there is an increasing demand for the development of effective and inexpensive approaches for the cleaning-up of the oily pollution in water system. In this study, a self-cleaning underwater superoleophobic mesh t...
متن کاملCharge separation from the bursting of bubbles on water.
Film droplets formed from the bursting of 2.4 mm diameter bubbles on the surface of pure water are predominantly negatively charged. The charge generated per bubble varies chaotically; a few bubbles generate more than -3 × 10(6) elementary charges (e) but the vast majority generate much less. The average is -5 × 10(4)e/bubble, and it is not significantly affected by bubbling rate or temperature...
متن کاملControl of Laminar Separation Bubbles
In the present paper active separation control of a transitional laminar separation bubble is investigated by means of direct numerical simulations. The specific influence of different forcing amplitudes and disturbance modes on the size and shape of the laminar separation bubble are illustrated. These consist of steady and unsteady twoand three-dimensional Tollmien– Schlichting-(TS)-like bound...
متن کاملGas Separation
Gas separation only became a major industrial application of membrane technology in the past 30 years, but the study of gas permeation through membranes has a long history. Systematic studies began with Thomas Graham who, over a period of 20 years, measured the permeation rates of all the gases then known, through every diaphragm available to him [1]. This was no small task because his experime...
