Chemical and structural heterogeneity and the resulting interaction of coexisting phases can lead to extraordinary behaviours in oxides, as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. However, such phenomena are rare in metallic alloys. Here we show that, by tuning the presence of structural heterogeneity(More)
1,3-bis{2-(4-methylpyridyl)imino}isoindoline (4-MeInH) reacts with copper(II) acetate and 2,4,6-trimercaptotriazine (H3TMTA) to yield [Cu(4-MeIn)]3(TMTA), a trinuclear propeller complex composed of three Cu(4-MeIn) ‘‘blades’’ coordinated to a 2,4,6-trimercaptotriazine (TMTA) ‘‘hub’’. Each copper(II) center is coordinated via a exocyclic sulfur and a ring(More)

We have used the near-field scanning microwave microscopy (NSMM) technique in the 1-10 GHz range to monitor the free water content of skin. The water content is interpreted from the measured dielectric properties of the epidermis. The finger skin was first hydrated by soaking in water at 37 degrees C for 30 min followed by monitoring of water content as the(More)
A monophasic sample of Ag2MnSn3S8 has been prepared by heating stoichiometric amounts of the constituent metals and sulfur in evacuated silica tubes at 670° C. Structural analysis of Ag2MnSn3S8 using Rietveld refinement of powder X-ray diffraction data shows that it crystallizes in the Fd3%m space group with a — 10:6984ð2Þ A. Magnetization measurements in(More)
