Industrial oil spills into aquatic environments can have catastrophic environmental effects. First responders to oil spills along the coast of the Gulf of Mexico in the southern United States have used spunbond nylon fabric bags and fences to separate spilled oil and oil waste from contaminated water. Low area mass density spunbond nylon is capable of sorbing more than 16 times its mass in low ...

The major sesquiterpene constituents of East-Indian sandalwood oil (Z)-α- and (Z)-β-santalols have shown to be responsible for most of the biological activities and organoleptic properties of sandalwood oil. The work reported here describes the strategic use of medium pressure liquid chromatography (MPLC) for the separation of both α- and β-santalenes and (Z)-α- and (Z)-β-santalols. Silver nitr...

Superoleophobic surfaces are of interest for anti-fouling, self-cleaning, anti-smudge, low-drag, anti-fog, and oil-water separation applications. Current bioinspired surfaces are of limited use due to a lack of mechanical durability. A so-called layer-by-layer approach, involving charged species with electrostatic interactions between layers, can provide the flexibility needed to improve adhesi...

Electrospun cellulose acetate nanofibers (CA-NF) have been modified with perfluoro alkoxysilanes (FS/CA-NF) for tailoring their chemical and physical features aiming oil-water separation purposes. Strikingly, hybrid FS/CA-NF showed that perfluoro groups are rigidly positioned on the outer surface of the nanofibers providing superhydrophobic characteristic with a water contact angle of ∼155°. De...

Usage of herbal medicine has been under so much attention for many years. They are gradually replacing synthetic drugs in pharmaceutical fields due to their fewer side effects. Nowadays, essential oils are widely used for the treatment of diseases as well as being applied as pesticide. In this study, 32 components of Zingiber essential oil were identified representing 97.42% of the extracted oi...

A new approach to the separation of multiple stacked cards is presented. Separation of multiple stacked cards is a key operation in many mechatronic devices such as copy machines and cash dispensers. Separation must be performed in small operation area despite of water and oil on the cards. In this article, we will develop a new system to separate multiple stacked cards using an array of absorp...

Thermally induced phase separation (TIPS) and thermal imidization were used to prepare PI-based monoliths in sequence. The hybridized PI (PI-co-POSS) exhibit potential liquid diode application achieve oil–water separation.
