The radiation hardness and thermal stability of the electrical characteristics of atomic layer deposited Al2O3 layers to be used as passivation films for silicon radiation detectors with slim edges are investigated. To directly measure the interface charge and to evaluate its change with the ionizing dose, metal-oxide-silicon (MOS) capacitors implementing differently processed Al2O3 layers were...

We have developed a characterization of the geological evolution of the Earth’s atmosphere and surface in order to model the observable spectra of an Earth-like planet through its geological history. These calculations are designed to guide the interpretation of an observed spectrum of such a planet by future instruments that will characterize exoplanets. Our models focus on planetary environme...

Development of photofragmentation-based diagnostic concepts for studying H2O2, H2O, HO2 and O3 in three different measurement environments, i.e. a flow of vaporized H2O2/H2O, a premixed laminar methane/air flame and a plasma, produced by a gliding arc discharge, are reported in this thesis project. In addition, quantitative NO2 laser-induced fluorescence, LIF, measurements in a plasma generated...

[1] In order to validate the reported precision of space‐based atmospheric composition measurements, validation studies often focus on measurements in the tropical stratosphere, where natural variability is weak. The scatter in tropical measurements can then be used as an upper limit on single‐profile measurement precision. Here we introduce a method of quantifying the scatter of tropical measu...

Upper tropospheric and lower stratospheric measurements from the Aura Microwave Limb Sounder (MLS), the Aura High Resolution Dynamics Limb Sounder (HIRDLS), and the Atmospheric Chemistry Experiment-Fourier transform spectrometer (ACE-FTS) are used to present the first global climatological comparison of extratropical, nonpolar trace gas distributions in double-tropopause (DT) and single-tropopa...

[1] Error covariances and vertical resolutions are reported for Tropospheric Emission Spectrometer (TES) nadir-view retrievals of surface temperature, atmospheric temperature, H2O, O3, CO, and CH4. These error covariances are computed as a result of selecting spectral windows that maximize the information content of simulated, TES nadir-view atmospheric retrievals of four regions representative...

In a fundamental process throughout nature, reduced iron unleashes the oxidative power of hydrogen peroxide into reactive intermediates. However, notwithstanding much work, the mechanism by which Fe(2+) catalyzes H2O2 oxidations and the identity of the participating intermediates remain controversial. Here we report the prompt formation of O=Fe(IV)Cl3(-) and chloride-bridged di-iron O=Fe(IV) · ...

Methylenedisalicylic acid was prepared as reported by the condensation reaction of salicylic acid with formaldehyde under acidic conditions. The complexes were prepared by refluxing ethanolic solutions of Methylenedisalicylic acid and some metal (II) salts. The ligand and its divalent metal complexes were characterized by solubility, melting point/decomposition temperature, molar conductance, a...

Two coordination polymers involving Cd(II), i.e., [Cd2(IDPA)2(bpe) (H2O)2]n·2n(H2O) (1) (H2IDPA is 5-(1-oxoisoindolin-2-yl)isophthalic acid, bpe 1,2-bis(4-pyridyl)ethane, 4-bpmh N, N-bis-pyridin-4-ylmethylene-hydrazine), and [Cd(IDPA)(4-bpmh)0.5(H2O)2]n·n(H2O) (2) are prepared under solvothermal conditions via tuning the auxiliary ligand from to 4-bpmh. Moreover, as-prepared complexes 1–2 revea...
