Sommario/riassunto |

"Seeking to re-imagine the meaning and significance of the international border, Opening the Floodgates makes a case for eliminating the border as a legal construct that impedes the movement of people into this country. Open migration policies deserve fuller analysis, as evidenced by President Barack Obama's pledge to make immigration reform a priority. Kevin R. Johnson offers an alternative vision of how U.S. borders might be reconfigured, grounded in moral, economic, and policy arguments for open borders. Importantly, liberalizing migration through an open borders policy would recognize that the enforcement of closed borders cannot stifle the strong, perhaps irresistible, economic, social, and political pressures that fuel international migration. Controversially, Johnson suggests that open |

borders are entirely consistent with efforts to prevent terrorism that have dominated immigration enforcement since the events of September 11, 2001. More liberal migration, he suggests, would allow for full attention to be paid to the true dangers to public safety and national security."-from Amazon.com |

Sommario/riassunto |
|
Molecular magnets show many properties not met in conventional metallic magnetic materials, i.e. low density, transparency to electromagnetic radiation, sensitivity to external stimuli such as light, pressure, temperature, chemical modification or magnetic/electric fields, and others. They can serve as "functional" materials in sensors of different types or be applied in high-density magnetic storage or nanoscale devices. Research into molecule-based materials became more intense at the end of the 20th century and is now an important branch of modern science. The articles in this Special Issue, written by physicists and chemists, reflect the current work on molecular magnets being carried out in several research centers. Theoretical papers in the issue concern the influence of spin anisotropy in the low dimensional lattice of the resulting type of magnet, as well as thermodynamics and magnetic excitations in spin trimers. The impact of external pressure on structural and magnetic properties and its underlying mechanisms is described using the example of Prussian blue analogue data. The other functionality discussed is the magnetocaloric effect, investigated in |

coordination polymers and high spin clusters. In this issue, new molecular magnets are presented: (i) ferromagnetic high-spin [Mn6] single-molecule magnets, (ii) solvatomagnetic compounds changing their structure and magnetism dependent on water content, and (iii) a family of purely organic magnetic materials. Finally, an advanced calorimetric study of anisotropy in magnetic molecular superconductors is reviewed. |
