Spin-crossover (SC) materials are transition metal complexes with 3d n, where n=4…7, electronic configurations which can exist in thermal equilibrium in the high-spin (HS) or low-spin (LS) ground state depending on the strength of octahedral ligand field.
This material was synthesized via a sol-gel transition.
An important feature of metal-filled polymeric materials is a transition from insulating to conducting behaviour over a narrow range of the volume fraction of the conductive filler.
"There were transition zones.
That's transition being better.
The use of superconductors in magnets is limited by the fact that strong magnetic fields above a certain critical value, depending upon the material, cause a superconductor to revert to its normal, or nonsuperconducting, state, even though the material is kept well below the transition temperature.
Consequently precipitate-free zones, referred to as "β flecks", remain within the beta matrix when the material is solution treated above the transition temperature and subsequently aged at temperatures between 454 °C and 538 °C.
The aim of this work is to describe a numerical framework for reliably and robustly simulating the different kinematic conditions exhibited by granular materials while spreading – from a stagnant condition, when the material is at rest, to a transition to granular flow, and back to a deposit profile.
In the temperature interval between a liquidus and glass transition temperature, the material is a supercooled liquid with the same property behavior as that of the melt above the melting temperature.
Specifically, it was found that by increasing the PLA PEG ratio, the degree of water uptake and the mechanical strength of the material is significantly decreased, while the glass transition temperature and degradation of the PEG PLA polymers are delayed.
