Magma flowing upward to form fresh crust along the axis of plate spreading does not appear to come exclusively from a narrow zone directly beneath the axis. Rather, molten material is distributed along the ridge in a region more than 100 km wide and over 100 km deep. Moreover, the melt zone is centered to one side of the axis—beneath the faster moving plate.
In a drive to help the US semiconductor industry, researchers are developing x‐ray spectrometers that will be able not just to identify any element in microscopic contaminants, but also to yield information about the element's chemical state.
The ability of ferroelectric materials to switch robustly from one polarization state to another forms the basis of a new thin film technology for storing data.
The demand for more sophisticated sensors and actuators in industrial equipment and consumer products is behind today's push for new transducer materials and geometries.
Schrodinger intended his gedanken experiment of a hapless cat mortally entangled with a quantum trigger as a reductio ad absurdum. But nowadays such experiments are being realized in laboratories—without offending the antivivisectionists
