Sometimes a picture says it all.
If it's listed this way in the directory, it must be true.
Our major research goal this summer is to find out what conditions are necessary for reliable SERS of proteins. Lots of people are interested in this for many different reasons. Ours are to further collaborations with some colleagues in the biology department who are interested in finding out some structural information about proteins they are studying. Hopefully as we work on this we’ll be able to get some general information about what one needs to think about in doing SERS with proteins.
We’ve started by trying to reproduce literature results. You’d think that would be easy, but it isn’t turning out to be the case. As an example, consider lysozyme. I have four published reports of lysozyme SERS, and all four have markedly different SERS spectra. Each is reviewed in chronological order below the fold.
Teaching revision as encouraging interdependence does not mean withholding critique or going soft on students. But it does mean that more than deliver prescriptions or justify grades, teacher comments on drafts should challenge writers with options and spark further conversation.
Scientists Observe Liquid Water Below Freezing
In a their study, Dino Leporini of the University of Pisa in Italy and his colleagues at the Indian Institute of Science in Bangalore say they have seen two new phases of liquid water when the water is cooled to low temperatures and squeezed to high pressures.
