During the 2010 Deepwater Horizon oil well accident in Gulf of Mexico, an treatment agent, normally used for slicks spread on sea surface, was sprayed into water first time world. However, details how it were unclear. Subsequently, experimental and theoretical studies use agents conducted Norway United States．At same time, authors a series this issue. The purpose spraying to combat spilled from...

SERS detection of quinacridone quinone (QAQ), an insoluble synthetic organic pigment relevant to modern artworks, is reported here. The use of ionic liquids (BMIMCl and TBAN) as dispersing agents has allowed us to carry out electrochemical SERS experiments of QAQ in aqueous solution using a Cu electrode. No SERS spectra were obtained either from the ionic liquids (ILs) or from QAQ when silver/g...

Coupling agents in wood fiber and polymer composites (WFPC) play a very important role in improving the compatibility and adhesion between polar wood fibers and non-polar polymeric matrices. In this paper, we review coupling agents, pretreatment, and mixing technology for wood fiber and polymer currenrly used in the manufacture of WFPC. So far, over forty coupling agents have been used in produ...

Anionic polyurethane dispersants APUDs were used as dispersing agents in formulation of waterborne paints. The APUDs were synthesized by three steps. In the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diisocyanate IPDI, dimethylol propionic acid DMPA in presence of acetone as solvent and dibutyltin dilaurate DBTDL as catalyst. Then, carboxylic polyure...
