In Silico Atom Labeling for the Reconstruction of Atom-mapped Metabolic Networks

Vassily Hatzimanikatis, Jasmin Maria Hafner, Noushin Hadadi

Field of atom mapping of metabolic networks is lacking an automated approach, which accounts for the information of reaction mechanism for atom mapping and is extendable from atom-mapped reactions to atom-mapped reaction networks. We developed “iAM.NICE” ( ...

Photo-Ionic Cells: Two Solutions to Store Solar Energy and Generate Electricity on Demand

Hubert Girault, Pekka Eero Peljo, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon

A solar energy conversion concept based on the photo-induced separation of a pair of redox species in a biphasic liquid cell is presented. The redox pair is subsequently discharged in an electrochemical flow cell to generate electricity. To illustrate this ...

Interfacial Self-Assembly as Catalytic Platform for Multielectron Redox Reactions

Astrid Johana Olaya Avendano

In Nature, many vital biological processes take place across the interface formed between two dielectric media. For instance, photosynthesis and aerobic respiration involve a series of redox reactions occurring across energy-transducing membranes, in charg ...

Subtle Changes, Dramatic Effects: Homogeneous Catalysis of the Oxygen-Reduction Reaction

Micheal Diarmaid Scanlon

A just cause: Fukuzumi and co-workers have employed experimental methods to tease out “cause and effect” relationships between subtle modification of the catalyst design or reaction conditions and the resultant changes in the homogeneous oxygen-reduction m ...

Chromium Poisoning

Josef Andreas Schuler

This thesis focuses on Cr-poisoning in solid oxide fuel cells (SOFC), which currently presents a key challenge for the development of this technology. By the implementation of dedicated experimental tools, this work offers a new access to, and comprehensio ...

Effect of the spectral properties of TiO2, Cu, TiO2/Cu sputtered films on the bacterial inactivation under low intensity actinic light

César Pulgarin, Juan Kiwi, Sami Rtimi, Rosendo Sanjines, Oualid Baghriche

Bacterial inactivation by TiO2, Cu and TiO2/Cu DC-magnetron sputtered thin films was systematically investigated in the dark and under low intensity visible/actinic light. Low intensity actinic light led to a fast 6log10 (complete) bacterial inactivation w ...

Promotional Effect of Ni in the Selective Gas-Phase Hydrogenation of Chloronitrobenzene over Cu-based Catalysts

Lioubov Kiwi, Javier Perez-Ramirez, Fernando Cardenas Lizana

We present 100?% selectivity to p-chloroaniline through the continuous gas-phase (atmospheric pressure; T=393523 K) catalytic hydrogenation of p-chloronitrobenzene over an activated Cu?Al (molar Cu/Al ratio 3:1) hydrotalcite. The synthesis by continuous co ...

RedOx Stability of Anode Supported Solid Oxide Fuel Cells

Antonin Faes

The weakness of nickel-based solid oxide fuel cell anodes is their low ability to withstand re-oxidation at working temperature, especially for the anode-supported cell design. The volume expansion coming along with nickel (Ni) oxidation induces stresses i ...

Investigation of the photoinduced electron injection processes for p-type triphenylamine-sensitized solar cells

Ulf Anders Hagfeldt

We have carried out theor. investigation aiming at modeling the assessment of mechanisms of photoinduced processes in a recent p-type org. metal-free dye derived from the triphenylamine (P-1) structure. In the P-1 system, one uses the triphenylamine moiety ...

Graphene Nanoplatelet Cathode for Co(III)/(II) Mediated Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Ladislav Kavan

Graphene nanoplatelets (GNP) in the form of thin semitransparent film on F-doped SnO2 (FTO) exhibit high electrocatalytic activity for Co(L)(2); where L is 6-(1H-pyrazol-1-yl)-2,2'-bipyridine. The exchange current densities for the Co(2+/)3(+)(L)(2) redox ...
