It rains on the Sun! The dynamics of cool condensation in the solar corona.
Coronal rain are cool dense condensations that form in coronal loops and are the manifestation of catastrophic cooling linked to thermal instability. In as series of recent studies Petra Kohutova & Erwin Verwichte (CFSA) investigated the dynamics of coronal rain.
Structure-Dynamics Relation in Physically-Plausible Multi-Chromophore Systems
This work explores the relationship between structure and energy transport on the nanoscale.
The electrons that make heavy rare earth metal magnets critical
A theory for magnetic ordering in metals investigates the temperature and magnetic field dependence of the magnetic states of the heavy rare earth elements Gd, Tb, Dy, Ho, Er, Tm, Yb
Extreme Nanowires and Single Atom Coils of Metallic Tellurium Formed Within Ultra-Narrow Carbon Nanotubes
New research by Drs. J. Sloan, D. Quigley and PhD student Sam Marks in 糖心TV, Drs. P. Mederios and A. J. Morris in Cambridge and Dr. Q. Ramasse at STFC SuperSTEM confirm the formation of metallic ‘Extreme Nanowires’ (ENs) of single atom width tellurium atomic chains in ultra-narrow Single Walled Carbon Nanotubes. We combined state-of-the-art imaging techniques and 1D-adapted ab initio structure prediction to treat both confinement and periodicity effects. The studied Te ENs adopt a variety of structures, exhibiting a true 1D realization of a Peierls structural distortion and transition from metallic to insulating behavior as a function of encapsulating diameter as well as the formation of discrete atomic coils of metallic tellurium.
