University of California - San Diego Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published in in the early edition of the Proceedings of the National Academy of Sciences the week of May 26 and the May 30 issue of Physical Review Letters. DNA is a long, unwieldy molecule that tends to repel itself because it is negatively charged, yet it...

Novel Approach To Measuring Surface Properties With New NIST Nanoscale Indenter
2013-07-24 09:48:17

National Institute of Standards and Technology Researchers from the National Institute of Standards and Technology (NIST) and the University of North Carolina have demonstrated a new design for an instrument, a "instrumented nanoscale indenter," that makes sensitive measurements of the mechanical properties of thin films -- ranging from auto body coatings to microelectronic devices -- and biomaterials. The NIST instrument uses a unique technique for precisely measuring the depth of the...
