New technique excites atoms and molecules using pulsed laser

The best method to obtain the most precise information on the inner structure of atoms and molecules is to excite them by means of resonant laser light. Unfortunately, just this laser light (above a certain intensity) can ...

New method for imaging defects in magnetic nanodevices

(Phys.org)—A team of researchers from the NIST Center for Nanoscale Science and Technology, the Royal Institute of Technology, Stockholm, and the University of Maryland have demonstrated a microscopy method to identify ...

Unique approach to materials allows temperature-stable circuits

(Phys.org) -- Sandia National Laboratories researcher Steve Dai jokes that his approach to creating materials whose properties won’t degenerate during temperature swings is a lot like cooking — mixing ingredients ...

Toppling Raman shift in supercritical carbon dioxide

(PhysOrg.com) -- Just as a wine glass vibrates and sometimes breaks when a diva sings the right note, carbon dioxide vibrates when light or heat serenades it. When it does, carbon dioxide exhibits a vibrational puzzle known ...

Innovation promises expanded roles for microsensors

Researchers have learned how to improve the performance of sensors that use tiny vibrating microcantilevers to detect chemical and biological agents for applications from national security to food processing.

New biosensor is based on a nanowire crystal array

(PhysOrg.com) -- A quick, inexpensive and highly sensitive test that identifies disease markers or other molecules in low-concentration solutions could be the result of a Cornell-developed nanomechanical biosensor, which ...
