1. Because the surfaces of nanocrystallines are coated by oleophilic long alkyl chain, they are incompatible with water surroundings to form some repulsion.

2. Oleophilic: Oil receptive property such as image areas of printing plates.

3. To achieve this, pellets containing nutrients and an oleophilic ( hydrocarbon soluble ) preparation have been used.

4. This can provide reference for the oleophilic modification of porous ceramics filtering ball and the treatment of wastewater containing oil by coalescence filtration technique.

5. One unique pretreatment with carbonate or bicarbonate of the raw materials results in hydrophilic oleophilic bi-functional products.

6. In various reasons, it is a main reason that oleophilic, low -molecular weight substances which lower surface tention concentrate at the wod surfaces during storage.
