Reports from University of Toulouse Provide New Insights into Chemical Physics (Tuning the spin crossover in nano-objects: From hollow to core-shell particles)

By a News Reporter-Staff News Editor at Physics Week -- Researchers detail new data in Chemical Physics. According to news reporting from Toulouse, France, by VerticalNews journalists, research stated, "Core-shell nanoparticles displaying spin crossover (SCO) effect on the shell and/or on the core are studied using Monte Carlo simulations of an elastic microscopic Ising-like model. In this Letter we demonstrate that the SCO transition temperature can be controlled by adjusting the width of the shell and the width of the core as well as the misfit between the lattice constants."

The news correspondents obtained a quote from the research from the University of Toulouse, "An original coupled system with a SCO active shell and an active core with another SCO material is proposed. Inducing the transition of the core by the spin transition of the shell results in a hysteresis in the thermal spin transition of the shell."

According to the news reporters, the research concluded: "This new type of memory effect in SCO compounds is based on the engineering of particle morphology."
