Synchrotron based Transmission x-ray microscopy reveals smectite fine structure in an aqueous environment
Synchrotron Transmission x-ray microscopy reveals smectite fine structure aqueous environment
2012/3/30
The unusual behaviour of smectites, the ability to change volume when wetted (swelling) or dried (shrinking), make soil containing smectites very unstable and hazardous for the building industry due t...

Synchrotron radio emission in radio-quiet AGNs
Synchrotron radio emission radio-quiet AGNs
2011/1/11
The basic mechanism responsible for radio emission in radio-loud active galactic nuclei (AGNs) is assumed to be synchrotron radiation. We suggest here that radio emission in radio-quiet objects is als...
