rn. In laboratory tests they found that one brand of Brazilian coffee contained almost 9 percent corn. Although noting that their results are preliminary, the scientists say their new method appears to be a significant improvement over existing tests to detect corn adulteration.

Nanomagnetic sponges to clean precious works of art
Chemists in Italy are reporting a real breakthrough in technology for cleaning and conserving priceless oil paintings, marble sculptures and other works of art in an article in the Aug. 14 issue of ACS Langmuir, a bi-weekly journal. In the report, Piero Baglioni and colleagues describe development and successful testing on artworks of nanomagnetic sponges that could have a range of other applications in cosmetics, detergents, and biotechnology.
Highlighting potential uses in art conservation, the report explains that conservators often use solvents and other cleaning agents in a gel formulation, somewhat similar in consistency to gelatin desert. Compared to liquids, gels have less of a tendency to soak deep into the surface of artwork and cause damage. Gels, however, are difficultPage: 1 2 3 4 5 6 7 8 Related biology news :1
