Radio emission of SN1993J. The complete picture: II. Simultaneous fit of expansion and radio light curves

open access: yes, 2010
We report on a simultaneous modelling of the expansion and radio light curves of SN1993J. We have developed a simulation code capable of generating synthetic expansion and radio light curves of supernovae by taking into consideration the evolution of the

Evaluating past and future building operational emissions: improved method

open access: yesBuildings & Cities
A simple method is presented to improve the evaluation of past and/or future CO2 emissions of heating and/or cooling a building. The degree-day—energy emission coefficient (DD-EEC) method relies on two established techniques.

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...
