Breakthrough method in nanoparticle synthesis paves the way for new pharmaceutical and biomedical applications

...wet-chemical technique uses two different types of surfactant (a soluble chemical compound that reduces the surface tension between liquids). One surfactant acts as the template for mesoporous structure, while the other is used to limit the growth of the pa...

Roundup®highly lethal to amphibians, finds University of Pittsburgh researcher

...ate the waxy surfaces of plants. In Roundup®, that surfactant is a chemical called polyethoxylated tallowamine. Other herbicides have less dangerous surfactants: For example, Relyea's study found that 2,4-D had no effect on tadpoles. "We've repeated the experiment, so we're confident that this is, in fact, a r...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

...notable observations were that increased levels of surfactant apoprotein B protein normally caused by nicotine were reduced by vitamin C. In addition, elastin levels in the lungs appeared to be slightly impacted by vitamin C. This finding may be significant as elastin plays a key role in the expansion and contr...
