Perovskite iridates have emerged as a new paradigm for studying the strongly correlated electron physics with strong spin-orbit coupling. The “113” alkaline-earth iridates AIrO3 (A = Ca, Sr, Ba) display a rich variety of crystallographic and electronic states and are now attracting growing research interest. This chapter aims to provide an overview for these “113” iridates, including the materi...

The frequency response of quartz crystal microbalance loaded by single-drop liquid is studied in this paper. Previous studies have shown that the relationship between resonant frequency and properties of liquid by completely immersing one side of the crystal in liquid. In this work, only localized portion of crystal was wetted by liquid droplet. Repeated experiment shows the relationship betwee...

The aim of the present study was to evaluate the properties of linear andnonlinear optics of the Schiff base Salen. Crystal structure of nanoparticles wasdetermined by a Bruker make diffractometer, Cu-K X-rays of wavelength (=1.5406Å). The XRD patterns were recorded in the 2 range of 10–90o with a step width of 0.02s-1. The UV-Vis Spectra recorded on a computerized double - beam Shimadzu 255...

abstract: two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (h2l5), and 1,10-phenanthroline（phen） and 1,3-di(4-pyridyl)propane (bpp) as secondary ligands are reported. they are formulated as {[pb(hl5)2(phen)(h2o)]·h2o}n(1), [zn2(hl5)4(bpp)2]n(2). all the complexes are characterized by single-crystal x-ray diffractions. compoud 1 crystallizes in the triclini...
