A mission to discover and characterise Earth-sized planets and super-Earths orbiting Sun-like stars in the habitable zone of the solar system – scientifically led by the University of Warwick - has been given the go-ahead today by the European Space Agency (ESA).
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.
This work explores the relationship between structure and energy transport on the nanoscale.
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 Warwick, 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.
The shock fronts of waves and plasma motions in the Sun'’s atmosphere produce radio emission via accelerated electrons. We analyse a series of quasi-periodic waves and the related radio features.
