Italian researchers show that acrylic polymers usually employed in works of art (or architecture) conservation and highly insoluble inorganic deposits containing organic materials can be solubilized in an oil-in-water microemulsions from nonionic surfactants and that a complete cleaning of an acrylic-contaminated painting can be successfully achieved.
With a nod to one of nature's best surface chemists - an obscure desert beetle - polymer scientists have devised a convenient way to construct test surfaces with a variable affinity for water, so that the same surface can range from superhydrophilic to superhydrophobic, and everything in between.
Imagine being able to rapidly identify tiny biological molecules such as DNA and toxins using a system that can fit on a microchip or in a drop of salt water. Itâ€™s closer than you might think, say a team of researchers.
Prof. Rip's talk, entitled "Addressing Societal Implications of Nanotechnology - and Their Ambivalencies," will provide an overview of the science and its impacts to society, and as well as identify eight key ambivalencies that arise as a result of nanotechnology's rapid growth and progress.
