Unraveling the complexity of oxygen reactions on Pt surfaces

Rainer Beck, Ana Gutiérrez González

Platinum (Pt) is a key material in automotive catalytic converters used to clean up the exhaust of the combustion engine. Pt particles in a ceramic matrix serve as an oxidation catalyst to eliminate toxic carbon monoxide (CO) and unburned hydrocarbons (CxH ...

Multispectral Near-Infrared Optical Tomography for Cancer Hypoxia Study in Mice

Scott Anthony Lindner, Matthias Wolf, Jingjing Jiang, Markus Rudin

Oxygenation of a tumor is one of the most important predictive factors: hypoxia is associated with aggressive tumors and substantially lower survival rate. Despite this high relevance of tumor oxygenation, there is currently no bedside technique available ...

Hazard and risk assessment of earthquake-induced landslides-case study

Landslides as secondary seismic effects are causing some patterns of soil failure that are often considered among the most destructive ones. In fact, the impact from triggered landslides has sometimes exceeded damage directly related to strong shaking and ...

Photoinduced disinfection in sunlit natural waters: Measurement of the second order inactivation rate constants between E-coli and photogenerated transient species

César Pulgarin, Stefanos Giannakis, Jean Arnaud Troyon

This work uncovers the implications of the estimation of exogenous inactivation rates for E. coli after the initial lag phase, and presents a strategy for the determination of the second-order inactivation rate constants (k2nd) of these bacteria with relev ...

Negligible interaction of [Ru(Phen) 3 ] 2+ with human serum albumin makes it promising for a reliable in vivo assessment of the tissue oxygenation

Georges Wagnières, Veronika Huntosova

The interaction between a ruthenium - based water soluble oxygen probe ([Ru(Phen)3]2+, phen - phenanthroline) and human serum albumin (HSA) was investigated with the aim of describing the influence of HSA on the [Ru(Phen)3]2+ luminescence properties. Nowad ...

In vivo measurement of the tissue oxygenation by time-resolved luminescence spectroscopy of protoporphyrin IX: Strategies to minimize artefacts associated with photoproducts

Georges Wagnières, Emmanuel Louis Arthur Gerelli, Veronika Huntosova

The determination of the oxygen partial pressure (pO(2)) in real time in living biological tissues is of high interest for numerous therapeutics, including photodynamic therapy (PDT) and radiotherapy. The minimally invasive and real-time measurement of the ...

Surviving anoxia in marine sediments: The metabolic response of ubiquitous benthic foraminifera (Ammonia tepida)

Anders Meibom, Stéphane Laurent Escrig, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

High input of organic carbon and/or slowly renewing bottom waters frequently create periods with low dissolved oxygen concentrations on continental shelves and in coastal areas; such events can have strong impacts on benthic ecosystems. Among the meiofauna ...

Oxygen depletion in Lake Geneva

Robert Vincent Schwefel

Low oxygen concentrations remain a global concern for the ecological health of lakes. High nutrient inputs and climate-induced changes in stratification and mixing are anthropogenic threats which largely impact aquatic oxygen budgets and overall ecosystem ...

Effect of PpIX photoproducts formation on pO2 measurement by time-resolved delayed fluorescence spectroscopy of PpIX in solution and in vivo

Georges Wagnières, Emmanuel Louis Arthur Gerelli, Matthieu Philippe Emmanuel Zellweger, Veronika Huntosova

The measurement of Protoporphyrin IX delayed fluorescence lifetime is a minimally invasive method for monitoring the levels of oxygen in cells and tissues. The excitation of Protoporphyrin IX during this measurement can lead to the formation of photoproduc ...
