Synthesis and characterizations of N,N-bis(diphenylphosphino)ethylaniline derivatives and X-ray crystal structure of palladium (II), platinum (II) complexes

Rosario Scopelliti, Zhaofu Fei, Wee Han Ang

N,N-Bis(diphenylphosphino)ethylaniline compounds, Ph2PN-C6H4-C2H5, with ethyl groups at the ortho- and para-positions have been synthesized. Oxidation of the aminophosphines with hydrogen peroxide, elemental sulfur and selenium gave the corresponding ...

Two-Dimensional Magnetic Droplet Manipulation Platform for Miniaturized Bioanalytical Applications

Martinus Gijs, Ulrike Lehmann, Virendra Kumar Parashar, Caroline Vandevyver

We present a new approach for the manipulation of small liquid samples for the miniaturization of bioanalytical systems. In our system, minute liquid volumes are manipulated via the interaction of a changeable magnetic field and magnetic microparticles con ...

Ferrocene-Containing Optically Active Liquid-Crystalline Side-Chain Polysiloxanes with Planar Chirality

Toralf Scharf

Optically active liquid-crystalline side-chain polysiloxanes have been prepared by grafting planar chiral ferrocene-based vinyl monomers onto commercially available polyhydrosiloxane. Two ferrocene monomers have been synthesized: a linear-type monomer, whi ...

Synchrotron X-ray absorption of LaCoO3 perovskite

Rudolf Paul Wilhelm Jozef Struis

LaCoO3 perovskite was prepared at 700degreesC using citrate precursors. The product was then characterized with X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS). The powder XRD pattern indicates rhomboliedral (R (3) over barc) or its monocli ...
