Surfactant-free emulsion of epoxy resin/sodium alginate for achieving robust underwater superoleophobic coating via a combination of phase separation and biomineralization.

Underwater superoleophobic coatings exhibit promising prospects in the field of oil contamination resistance. However, their poor durability, stemming from the fragile structures and unstable hydrophilicity, greatly restricted their development. In this report, we proposed a novel strategy of combination water-induced phase separation and biomineralization to prepare the robust underwater superoleophobic epoxy resin-calcium alginate (EP-CA) coating by utilizing a surfactant-free emulsion of epoxy resin/sodium alginate (EP/SA).

Bio-inspired robust superhydrophilic/underwater superoleophobic coating with lubrication, anti-crude oil fouling and anti-corrosion performances.

The crude oil spill accidents cause numerous crude oil contaminations and oily wastewater. Underwater superoleophobic coating has excellent ability to resist crude oil contamination and separate oily wastewater. But it's hard to keep stable performance against the physical or chemical attack.

Measles epidemiology and survey of measles immunity level among healthy population in Baoji City, Shaanxi Province, China.

In this study, we analyzed the epidemiology of measles cases from January 2004 to December 2011 and measles immunity levels among a healthy population from January to June 2012, in Baoji, Shaanxi Province. This study aimed to identify susceptible populations to measles and to establish methods of measles prevention and control. Measles incidence was at the lowest level in 2011 (0.
