knock-offs are almost physically and chemically indistinguishable from the real thing. Scientists need a better way to identify adulterated honey, the researchers say.
Herbreteau and colleagues describe a new, highly sensitive test that uses a special type of chromatography to separate and identify complex sugars (polysaccharides) on their characteristic chemical fingerprints. To test their method, the scientists obtained three different varieties of pure honey from a single beekeeper and then prepared adulterated samples of the honeys by adding 1 percent corn syrup. They showed that the new technique accurately distinguished the impure honeys from the pure versions based on differences in their sugar content. MTS

New "smart" polymer reduces radioactive waste at nuclear power plants
Industrial & Engineering Chemistry Research
Scientists in Germany and India are reporting development of a new polymer that reduces the amount of radioactive waste produced during routine operation of nuclear reactors. Their study, which details a first-of-its-kind discovery, has been published in the ACS' Industrial & Engineering Chemistry Research, a bi-weekly journal.
Brje Sellergren and colleagues note that structural materials such as carbon steel in power plants' water cooling systems form deposits of metal oxides when they interact w
