Design of Surface-Supported Bio-inspired Networks for CO2 and O2 Activation at Room Temperature

The structure of a biological system defines its function. Therefore, nature has developed sophisticated systems that catalyze chemical reactions that are vital for life on earth. For instance, the photosynthesis is a biological process that is partially r ...

Nanoscale Lithography and Thermometry with Thermal Scanning Probes

Samuel Tobias Howell, Samuel Zimmermann

Thermal scanning probe lithography (t-SPL) is an advanced lithography technique in which a heated atomic force microscope tip locally modifies a sample material. Due to the nanometer-sized tip apex diameter, t-SPL enables patterning of sub-10 nm structures ...

Efficient Electrochemical Production of Peroxodicarbonate Applying DIACHEM (R) Diamond Electrodes

Christos Comninellis

The electrochemical synthesis of peroxodicarbonate was performed on boron-doped DIACHEM((R)) diamond anodes (BDD). The influence of various parameters was studied and promising conditions were determined in an undivided cell design by CONDIAS GmbH. The bes ...

One-Pot Polyol Synthesis of Pt/CeO2 and Au/CeO2 Nanopowders as Catalysts for CO Oxidation

Christian Ludwig, Andrea Testino, Mohamed Tarik, Frank Pilger

The facile one-pot synthesis of CeO2-based catalysts has been developed to prepare a relatively large amount of nanopowders with relevant catalytic activity towards CO oxidation. The method consists of a two-steps process carried out in ethylene glycol: in ...

Size and Shape-controlled Pd Nanocrystals on ZnO and SiO2: When the Nature of the Support Determines the Active Phase

Lioubov Kiwi, Rocio Micaela Crespo Quesada

The structure sensitivity of acetylene hydrogenation was studied over size-controlled cubic and octahedral Pd nanocrystals (NCs) supported on ZnO and SiO2. Acetylene hydrogenation was found to be structure sensitive [with Pd(111) in octahedra being more ac ...

Desiccation shrinkage of non-clayey soils: multi-physics mechanisms and a microstructural model

Lyesse Laloui, Hervé Péron

Analysis of macroscopic desiccation shrinkage experiments indicates that most, but not all of the shrinkage during drying occurs while soil is still saturated. Shrinkage practically ceases and air starts to penetrate the soil, when the water content is sti ...

Nature of the Charge Carriers and Conduction Mechanism in Anatase TiO2

Jacim Jacimovic

The anatase phase of TiO2 is a key material in the third generation of photovoltaics and for photo-catalytic devices. The number of promising applications, where one would profit from the electronic degrees of freedom of the material, like in memristors, s ...

Nitrous Oxide Abatement over Fe-Zeolite : Mechanistic Study of Decomposition and Reactor Development

Bryan Bromley

The use of zeolites for catalytic reactions is a field in continuous development. Since it was demonstrated that metal-zeolites are efficient catalysts for NOx abatement, decomposition of nitrous oxide (N2O) over Fe-containing zeolites has attracted great ...

Insights into the Origin of Cooperative Effects in the Spin Transition of [Fe(NH(2)trz)(3)](NO3)(2): the Role of Supramolecular Interactions Evidenced in the Crystal Structure of [Cu(NH(2)trz)(3)](NO3)(2)center dot H2O

Christine Neuhausen

The thermally induced hysteretic spin transition (ST) that occurs in the polymeric chain compound Fe(NH(2)trz)(3)(2) (1) above room temperature (T-c(sic) = 347 K, T-c(sic) = 314 K) has been tracked by Fe-57 Mossbauer spectroscopy, SQUID magnetometry ...
