Investigation of 2R-Cell Degradation under Thermal Cycling and RedOx Cycling Conditions by Electrochemical Impedance Spectroscopy

Jan Van Herle, Stefan Diethelm, Vaibhav Singh

A 2R-cell with a 10 cm2 active area LSCF cathode on a CGO buffer layer was tested at 780°C under thermal and RedOx cycling conditions; 20 thermal cycles were performed between 780°C and 100°C, using 200°C/h heating ramps and natural cooling, followed by 20 ...

Influence of crustal dust and sea spray supermicron particle concentrations and acidity on inorganic NO3- aerosol during the 2013 Southern Oxidant and Aerosol Study

Satoshi Takahama, Robin Lewis Modini

Inorganic aerosol composition was measured in the southeastern United States, a region that exhibits high aerosol mass loading during the summer, as part of the 2013 Southern Oxidant and Aerosol Study (SOAS) campaign. Measurements using a Monitor for AeRos ...

Organic nitrate aerosol formation via NO3 + biogenic volatile organic compounds in the southeastern United States

Satoshi Takahama, Christine Mohr

Gas- and aerosol-phase measurements of oxidants, biogenic volatile organic compounds (BVOCs) and organic nitrates made during the Southern Oxidant and Aerosol Study (SOAS campaign, Summer 2013) in central Alabama show that a nitrate radical (NO3) reaction ...

NanoSIMS isotopic imaging - Deciphering the nature of coral-symbiont metabolic interactions

Anders Meibom, Isabelle Domart-Coulon, Christophe Kopp, Thomas Krüger, Maoz Fine

The ability of endosymbiotic Symbiodinium to fix inorganic nutrients and their translocation to the coral host is considered a key element for the growth of coral reefs in tropical coastal waters and has been a fundamental research topic for over 50 years. ...

Effects of endogeic earthworms on the soil organic matter dynamics and the soil structure in urban and alluvial soil materials

Pascal Turberg, Jean-Michel Gobat, Renée-Claire Le Bayon

Earthworms are considered as key actors of soil processes at different spatial and temporal scales and provide essential ecosystem services linked to climate regulation or primary production. However, little is known about their basic functional roles (e.g ...

Effect of TiO2 Nanoparticles and UV Radiation on Extracellular Enzyme Activity of Intact Heterotrophic Biofilms

Kristin Schirmer, Laura Sigg, Hannah Inka Schug

When introduced into the aquatic environment, TiO2 NP are likely to settle from the water column, which results in increased exposure of benthic communities. Here, we show that the activity of two extracellular enzymes of intact heterotrophic biofilms, bet ...

Impacts by dams: From water quality modelling to management optimization

Alfred Johny Wüest

Dams are prone to causing negative effects on downstream ecosystems by their potential to alter riverine water quality. In the case of Itezhi-Tezhi Reservoir (Zambia), a nutrient-poor wetland located downstream is affected by low oxygen concentrations owin ...

Controls on diurnal streamflow cycles in a high altitude catchment in the Swiss Alps

Marc Parlange, Steven Vincent Weijs, Marc Calaf Bracons, Holly Jayne Oldroyd, Raphaël Mutzner

We study the diurnal streamflow cycles in a high altitude catchment where a large field campaign has been undertaken. In one monitored sub-basin, the cycle is evapotranspiration-dominated, in another, the cycle is icemelt-dominated. The two processes happe ...

Unified Strategy to Monoterpene Indole Alkaloids: Total Syntheses of (±)-Goniomitine, (±)-1,2-Dehydroaspidospermidine, (±)-Aspidospermidine, (±)-Vincadifformine, and (±)-Kopsihainanine A

Qian Wang, Jieping Zhu, Zhengren Xu, Olivier Wagnières

Total syntheses of (±)-goniomitine, (±)-1,2-dehydroaspidospermidine, (±)-aspidospermidine, (±)-vincadifformine, and (±)-kopsihainanine A were achieved featuring two common key steps: (1) a palladium-catalyzed decarboxylative vinylation that provides quick ...
