A combined synchrotron X-ray diffraction, Raman scattering, and infrared spectroscopy study of the pressure-induced changes in H3BO3 to 10 GPa revealed a new high-pressure phase transition between 1 and 2 GPa followed by chemical decomposition into cubic H ...
By using an oriented electric field in a scanning tunneling microscope, one can locally control the condensation of boronic acids at the liquid/solid interface. The phase transition between self-assembled molecular networks and covalent organic frameworks ...
This thesis focuses on the design and the synthesis of mono- and dinuclear iron clathrochelate complexes and their applications in materials science.
Dinuclear iron clathrochelate complexes can be synthesized in different oxidation states: i. as negative ...
Arsenic occurs in the +III oxidation state as a metastable species in oxic waters. Under oxic conditions, As(III) is both more mobile in natural waters and less efficiently removed by water treatment processes than As(V). Other oxidants, however, can react ...
A new one-pot synthesis of sulfoxides is presented. It involves the bora-ene reaction of sulfur dioxide and prop-2-ene-1-boronic esters, giving mixed anhydrides of sulfinic and boric acids. The latter react chemoselectively at the sulfur center with Grigna ...
Silicon dioxide (SiO2) films grown on silicon monocrystal (Si) substrates form the gate oxides in current Si-based microelectronics devices. The understanding at the atomic scale of both the silicon oxidation process and the properties of the Si(100)-SiO2 ...
The crystal structure of the new synthetic compound Ba-5[B20O33(OH)(4)] . H2O was established by the methods of X-ray diffraction (a Stoe IPDS diffractometer, lambda MoKalpha, 1860 independent reflections, anisotropic refinement, R = 1.95%, localization of ...
Microcrystalline silicon (μc-Si:H) layers deposited by the very high-frequency-glow discharge technique at a radio-frequency excitation of 70 MHz are observed to be basically slightly 〈n〉 type. By doping (so-called]] microdoping") with boron in the gas pha ...
Starting from phloroglucinol and resorcinol alpha ,alpha '-bichalcone I (R = H, MeO) was synthesized in three steps. The key step is the simultaneous condensation of one mole of 1,4-diketone II with two moles of anisaldehyde catalyzed with boric acid. [on ...
